I currently have a magic jack app on the machine but it is blinking terribly and as a result, I am unable to use my Magicjack phone. Where can I find the software? I think I just need to reinstall it. What do you think? Can you please assist? Please see my previous response. The ethernet cable is used for connecting directly to your router.
It is not used for connecting to your computer. That may solve a lot of frustration. Use only the USB connector to connect to your computer. AC adapter and ethernet cable are not required in this mode. Angel, You should not have any trouble connecting. The firmware should automatically install and connect. Usually, is an internet connection error.
Try a standard network reboot: 1. Power off your modem, router and magicJack. Wait two minutes. Turn on the power to the modem. Wait one minute. Connect modem to router if applicable. Connect magicJack to router. Check on your laptop to see if you can connect to any random website.
If you can view a website, make a call on magicJack. Try calling again. Your magicJack AC adapter should be just over five volts, but it may be either under or over charge. The software should auto-install. If none of these work, check with magicJack chat support. Im trying to find a driver for a majicJack bought about 4 years ago,.. You might consider updating it on a windows 7 or 8 machine — it should do it automatically when you plug it into the windows computer USB port.
The firmware on the device should then be updated. You could then try putting into the USB port on a mac OS10 to see if the firmware will at least recognize the mac machine and upgrade for the mac firmware automatically.
Alternatively, contact chat support at my. That way, ostensibly you could keep your number from your broken device and put it on a working device. This is apparently no longer working with magicJack devices and finding the executable has become rather difficult, so the question may be moot. I have used the magicjack classic usb one for years, actually i use on windows 8. You may want to hold off. Additionally, while some 8.
You may have to reboot before updated firmware takes effect. It is without doubt that this Magic Jack one of the best thing happened to me in communication. I have it for the past year. Now I am having a problem. I am now in Egypt. Thank you. Error 23 means you have to reserve an IP address for your magicJack, assuming your router is directly connected via Ethernet.
That way, whenever you connect your magicJack to the router, it will automatically use that IP. If you cannot reserve the IP, another method may be to disconnect and reconnect the power supply of your magicJack when you start getting the error.
The magicJack device has no such password interface. Unfortunately, this means that when you log off, your magicJack will no longer be granted access either. Hi Chris, Greetings from India! Since Feb I was having a problem connecting with MJ.
After fixing it I decided to read the other hits and found your website. You have given awesome support to so many people with MJ problems. Next time I have an issue I know where to look :- Cheers. Are you using the app on your cell phone or the physical device on your ethernet with a corded or cordless phone?
Perhaps, if you can provide specifics we can get to the heart of the matter. Richard Wiker: I have a dial tone, but not really a connection since the dialtone does not go away when I press the phone keypad. The best thing I can do for you now is to pass your Comment and suggestion to Appropriate Department. Richard Wiker: THat is fine to include my name. Please email me when the fix is made. Richard, Thank you so much for spearheading this. I tried uninstalling MJ with Terminal Commands and restart, then reinstall and still no luck.
The app just continues to hangs on launch. Paul, Again, thanks for your comments. I can not use magic jack with El Capitan either and i have no clue how to fix this.
Any suggestions. Cynthia, thanks so much for your comment. You and others are mentioned as a thank you on a new post on the subject. Hopefully magicJack will resolve this soon. As an input option, blocks all video streams of a file from being filtered or being automatically selected or mapped for any output. As an output option, disables video recording i. Select the pass number 1 or 2. It is used to do two-pass video encoding. The statistics of the video are recorded in the first pass into a log file see also the option -passlogfile , and in the second pass that log file is used to generate the video at the exact requested bitrate.
On pass 1, you may just deactivate audio and set output to null, examples for Windows and Unix:. This is an alias for -filter:v , see the -filter option. Automatically rotate the video according to file metadata.
Enabled by default, use -noautorotate to disable it. Automatically scale the video according to the resolution of first frame. Enabled by default, use -noautoscale to disable it. Therefore, it is not recommended to disable it unless you really know what you are doing.
Disable autoscale at your own risk. Set pixel format. If the selected pixel format can not be selected, ffmpeg will print a warning and select the best pixel format supported by the encoder. Rate control override for specific intervals, formatted as "int,int,int" list separated with slashes. Two first values are the beginning and end frame numbers, last one is quantizer to use if positive, or quality factor if negative. Use this option if your input file is interlaced and you want to keep the interlaced format for minimum losses.
The alternative is to deinterlace the input stream by use of a filter such as yadif or bwdif , but deinterlacing introduces losses. If the argument consists of timestamps, ffmpeg will round the specified times to the nearest output timestamp as per the encoder time base and force a keyframe at the first frame having timestamp equal or greater than the computed timestamp. Note that if the encoder time base is too coarse, then the keyframes may be forced on frames with timestamps lower than the specified time.
If one of the times is " chapters [ delta ]", it is expanded into the time of the beginning of all chapters in the file, shifted by delta , expressed as a time in seconds. This option can be useful to ensure that a seek point is present at a chapter mark or any other designated place in the output file.
For example, to insert a key frame at 5 minutes, plus key frames 0. If the argument is prefixed with expr: , the string expr is interpreted like an expression and is evaluated for each frame.
A key frame is forced in case the evaluation is non-zero. If the argument is source , ffmpeg will force a key frame if the current frame being encoded is marked as a key frame in its source.
In cases where this particular source frame has to be dropped, enforce the next available frame to become a key frame instead. Note that forcing too many keyframes is very harmful for the lookahead algorithms of certain encoders: using fixed-GOP options or similar would be more efficient. Initialise a new hardware device of type type called name , using the given device parameters.
The set of devices can also be filtered using the key-value pairs to find only devices matching particular platform or device strings. If device is an integer, it selects the device by its index in a system-dependent list of devices. If device is any other string, it selects the first device with a name containing that string as a substring. Initialise a new hardware device of type type called name , deriving it from the existing device with the name source.
Pass the hardware device called name to all filters in any filter graph. This can be used to set the device to upload to with the hwupload filter, or the device to map to with the hwmap filter. Other filters may also make use of this parameter when they require a hardware device.
Note that this is typically only required when the input is not already in hardware frames - when it is, filters will derive the device they require from the context of the frames they receive as input. Use hardware acceleration to decode the matching stream s. The allowed values of hwaccel are:. Unlike most other values, this option does not enable accelerated decoding that is used automatically whenever a qsv decoder is selected , but accelerated transcoding, without copying the frames into the system memory.
For it to work, both the decoder and the encoder must support QSV acceleration and no filters must be used. This option has no effect if the selected hwaccel is not available or not supported by the chosen decoder.
Note that most acceleration methods are intended for playback and will not be faster than software decoding on modern CPUs. Additionally, ffmpeg will usually need to copy the decoded frames from the GPU memory into the system memory, resulting in further performance loss. This option is thus mainly useful for testing. This option only makes sense when the -hwaccel option is also specified. List all hardware acceleration components enabled in this build of ffmpeg.
Actual runtime availability depends on the hardware and its suitable driver being installed. Set the number of audio frames to output. This is an obsolete alias for -frames:a , which you should use instead. Set the audio sampling frequency. For output streams it is set by default to the frequency of the corresponding input stream.
For input streams this option only makes sense for audio grabbing devices and raw demuxers and is mapped to the corresponding demuxer options. Set the number of audio channels. For output streams it is set by default to the number of input audio channels.
As an input option, blocks all audio streams of a file from being filtered or being automatically selected or mapped for any output. As an output option, disables audio recording i. Set the audio sample format. This is an alias for -filter:a , see the -filter option. If some input channel layout is not known, try to guess only if it corresponds to at most the specified number of channels.
For example, 2 tells to ffmpeg to recognize 1 channel as mono and 2 channels as stereo but not 6 channels as 5. The default is to always try to guess. Use 0 to disable all guessing. As an input option, blocks all subtitle streams of a file from being filtered or being automatically selected or mapped for any output.
As an output option, disables subtitle recording i. Fix subtitles durations. For each subtitle, wait for the next packet in the same stream and adjust the duration of the first to avoid overlap. This is necessary with some subtitles codecs, especially DVB subtitles, because the duration in the original packet is only a rough estimate and the end is actually marked by an empty subtitle frame. Failing to use this option when necessary can result in exaggerated durations or muxing failures due to non-monotonic timestamps.
Note that this option will delay the output of all data until the next subtitle packet is decoded: it may increase memory consumption and latency a lot. Designate one or more input streams as a source for the output file. Both indices start at 0. The first -map option on the command line specifies the source for output stream 0, the second -map option specifies the source for output stream 1, etc. A - character before the stream identifier creates a "negative" mapping.
It disables matching streams from already created mappings. A trailing? Note the map will still fail if an invalid input file index is used; such as if the map refers to a non-existent input.
For example, if you have two audio streams in the first input file, these streams are identified by "" and "". You can use -map to select which streams to place in an output file. For example:. For example, to select the stream with index 2 from input file a.
To map the video and audio streams from the first input, and using the trailing? Allow input streams with unknown type to be copied instead of failing if copying such streams is attempted. Map an audio channel from a given input to an output. For example, assuming INPUT is a stereo audio file, you can switch the two audio channels with the following command:.
The following example splits the channels of a stereo input into two separate streams, which are put into the same output file:. It is therefore not currently possible, for example, to turn two separate mono streams into a single stereo stream. However splitting a stereo stream into two single channel mono streams is possible.
If you need this feature, a possible workaround is to use the amerge filter. For example, if you need to merge a media here input. To map the first two audio channels from the first input, and using the trailing?
Set metadata information of the next output file from infile. Note that those are file indices zero-based , not filenames. A metadata specifier can have the following forms:. In an input metadata specifier, the first matching stream is copied from.
In an output metadata specifier, all matching streams are copied to. These default mappings are disabled by creating any mapping of the relevant type. A negative file index can be used to create a dummy mapping that just disables automatic copying. For example to copy metadata from the first stream of the input file to global metadata of the output file:. Note that simple 0 would work as well in this example, since global metadata is assumed by default. If no chapter mapping is specified, then chapters are copied from the first input file with at least one chapter.
Use a negative file index to disable any chapter copying. Show benchmarking information at the end of an encode. Shows real, system and user time used and maximum memory consumption. Maximum memory consumption is not supported on all systems, it will usually display as 0 if not supported. Show benchmarking information during the encode. Its value is a floating-point positive number which represents the maximum duration of media, in seconds, that should be ingested in one second of wallclock time.
Default value is zero and represents no imposed limitation on speed of ingestion. Value 1 represents real-time speed and is equivalent to -re. Mainly used to simulate a capture device or live input stream e. Should not be used with a low value when input is an actual capture device or live stream as it may cause packet loss. Video sync method. For compatibility reasons old values can be specified as numbers.
Newly added values will have to be specified as strings always. Frames are passed through with their timestamp or dropped so as to prevent 2 frames from having the same timestamp. As passthrough but destroys all timestamps, making the muxer generate fresh timestamps based on frame-rate. Note that the timestamps may be further modified by the muxer, after this.
With -map you can select from which stream the timestamps should be taken. You can leave either video or audio unchanged and sync the remaining stream s to the unchanged one. Frame drop threshold, which specifies how much behind video frames can be before they are dropped. In frame rate units, so 1. The default is One possible usecase is to avoid framedrops in case of noisy timestamps or to increase frame drop precision in case of exact timestamps.
Audio sync method. Pad the output audio stream s. This is the same as applying -af apad. Argument is a string of filter parameters composed the same as with the apad filter. Do not process input timestamps, but keep their values without trying to sanitize them. In particular, do not remove the initial start time offset value. Note that, depending on the vsync option or on specific muxer processing e.
This means that using e. Specify how to set the encoder timebase when stream copying. The time base is copied to the output encoder from the corresponding input demuxer. This is sometimes required to avoid non monotonically increasing timestamps when copying video streams with variable frame rate. Set the encoder timebase.
This field can be provided as a ratio of two integers e. Timestamp error delta threshold. Assign a new stream-id value to an output stream. This option should be specified prior to the output filename to which it applies. For the situation where multiple output files exist, a streamid may be reassigned to a different value.
Set bitstream filters for matching streams. Use the -bsfs option to get the list of bitstream filters. Specify Timecode for writing. Define a complex filtergraph, i. For simple graphs — those with one input and one output of the same type — see the -filter options. An unlabeled input will be connected to the first unused input stream of the matching type. Output link labels are referred to with -map. Unlabeled outputs are added to the first output file. Here [0:v] refers to the first video stream in the first input file, which is linked to the first main input of the overlay filter.
Similarly the first video stream in the second input is linked to the second overlay input of overlay. Assuming there is only one video stream in each input file, we can omit input labels, so the above is equivalent to. Furthermore we can omit the output label and the single output from the filter graph will be added to the output file automatically, so we can simply write. As a special exception, you can use a bitmap subtitle stream as input: it will be converted into a video with the same size as the largest video in the file, or x if no video is present.
Note that this is an experimental and temporary solution. It will be removed once libavfilter has proper support for subtitles. This option enables or disables accurate seeking in input files with the -ss option. It is enabled by default, so seeking is accurate when transcoding. This option enables or disables seeking by timestamp in input files with the -ss option. It is disabled by default.
If enabled, the argument to the -ss option is considered an actual timestamp, and is not offset by the start time of the file. This matters only for files which do not start from timestamp 0, such as transport streams. This option sets the maximum number of queued packets when reading from the file or device. By default ffmpeg only do this if multiple inputs are specified.
Print sdp information for an output stream to file. Requires at least one of the output formats to be rtp. Allows discarding specific streams or frames from streams. Any input stream can be fully discarded, using value all whereas selective discarding of frames from a stream occurs at the demuxer and is not supported by all demuxers. Set fraction of decoding frame failures across all inputs which when crossed ffmpeg will return exit code Crossing this threshold does not terminate processing.
Range is a floating-point number between 0 to 1. While waiting for that to happen, packets for other streams are buffered. This option sets the size of this buffer, in packets, for the matching output stream.
The default value of this option should be high enough for most uses, so only touch this option if you are sure that you need it. This is a minimum threshold until which the muxing queue size is not taken into account.
Defaults to 50 megabytes per stream, and is based on the overall size of packets passed to the muxer. If filter format negotiation requires a conversion, the initialization of the filters will fail.
Conversions can still be performed by inserting the relevant conversion filter scale, aresample in the graph. Check the presets directory in the FFmpeg source tree for examples. The fpre option takes the filename of the preset instead of a preset name as input and can be used for any kind of codec.
For the vpre , apre , and spre options, the options specified in a preset file are applied to the currently selected codec of the same type as the preset option. The argument passed to the vpre , apre , and spre preset options identifies the preset file to use according to the following rules:.
First ffmpeg searches for a file named arg. For example, if the argument is libvpxp , it will search for the file libvpxp. For example, if you select the video codec with -vcodec libvpx and use -vpre p , then it will search for the file libvpxp.
They work similar to ffpreset files, but they only allow encoder- specific options. When the pre option is specified, ffmpeg will look for files with the suffix. For example, if you select the video codec with -vcodec libvpx and use -pre p , then it will search for the file libvpxp. If no such file is found, then ffmpeg will search for a file named arg. Note that you must activate the right video source and channel before launching ffmpeg with any TV viewer such as xawtv by Gerd Knorr.
You also have to set the audio recording levels correctly with a standard mixer. The Y files use twice the resolution of the U and V files. They are raw files, without header. They can be generated by all decent video decoders. You must specify the size of the image with the -s option if ffmpeg cannot guess it.
Each frame is composed of the Y plane followed by the U and V planes at half vertical and horizontal resolution. Converts a. Furthermore, the audio stream is MP3-encoded so you need to enable LAME support by passing --enable-libmp3lame to configure. The mapping is particularly useful for DVD transcoding to get the desired audio language.
This will extract one video frame per second from the video and will output them in files named foo Images will be rescaled to fit the new WxH values. If you want to extract just a limited number of frames, you can use the above command in combination with the -frames:v or -t option, or in combination with -ss to start extracting from a certain point in time.
It is the same syntax supported by the C printf function, but only formats accepting a normal integer are suitable. The resulting output file test FFmpeg adopts the following quoting and escaping mechanism, unless explicitly specified.
The following rules are applied:. Note that you may need to add a second level of escaping when using the command line or a script, which depends on the syntax of the adopted shell language. Time is local time unless Z is appended, in which case it is interpreted as UTC. If the year-month-day part is not specified it takes the current year-month-day. HH expresses the number of hours, MM the number of minutes for a maximum of 2 digits, and SS the number of seconds for a maximum of 2 digits.
The m at the end expresses decimal value for SS. S expresses the number of seconds, with the optional decimal part m. Specify the size of the sourced video, it may be a string of the form width x height , or the name of a size abbreviation. Specify the frame rate of a video, expressed as the number of frames generated per second. A ratio can be expressed as an expression, or in the form numerator : denominator. It can be the name of a color as defined below case insensitive match or a [0x ]RRGGBB[AA] sequence, possibly followed by and a string representing the alpha component.
The alpha component may be a string composed by "0x" followed by an hexadecimal number or a decimal number between 0. A channel layout specifies the spatial disposition of the channels in a multi-channel audio stream. To specify a channel layout, FFmpeg makes use of a special syntax. Each term can be:.
Before libavutil version 53 the trailing character "c" to specify a number of channels was optional, but now it is required, while a channel layout mask can also be specified as a decimal number if and only if not followed by "c" or "C". Two expressions expr1 and expr2 can be combined to form another expression " expr1 ; expr2 ". Return 1 if x is greater than or equal to min and lesser than or equal to max , 0 otherwise. The results of the evaluation of x and y are converted to integers before executing the bitwise operation.
Note that both the conversion to integer and the conversion back to floating point can lose precision. Round the value of expression expr upwards to the nearest integer.
For example, "ceil 1. Round the value of expression expr downwards to the nearest integer. For example, "floor Return the greatest common divisor of x and y. If both x and y are 0 or either or both are less than zero then behavior is undefined. Evaluate x , and if the result is non-zero return the result of the evaluation of y , return 0 otherwise. Evaluate x , and if the result is non-zero return the evaluation result of y , otherwise the evaluation result of z.
Evaluate x , and if the result is zero return the result of the evaluation of y , return 0 otherwise. Evaluate x , and if the result is zero return the evaluation result of y , otherwise the evaluation result of z. Load the value of the internal variable with number var , which was previously stored with st var , expr. The function returns the loaded value. Print the value of expression t with loglevel l. If l is not specified then a default log level is used.
Returns the value of the expression printed. Return a pseudo random value between 0. Find an input value for which the function represented by expr with argument ld 0 is 0 in the interval When the expression evaluates to 0 then the corresponding input value will be returned. Round the value of expression expr to the nearest integer. For example, "round 1. Compute the square root of expr. Store the value of the expression expr in an internal variable.
The function returns the value stored in the internal variable. Note, Variables are currently not shared between expressions. Evaluate a Taylor series at x , given an expression representing the ld id -th derivative of a function at 0. It supports recording system sound, microphone voice, and both of them. The settings in "Options" helps you to adjust the volume. Step 3. Click on the "REC" button to start recording.
