I did realize that I had to download the newer ffmpeg X Binaries, and that did allow me to use the Play option, which triggered MPlayer. Is either of them the one you selected? And do you have any idea how come this thing is still processing (I set it to one minute as you suggested.) I do note that the AVI option is not actually in the drop down list but instead there is DivX mencoder and DivX ffmpeg. I tried your steps and after more than 10 minutes, it reads 19120 % !? And counting. The files it is producing are not recognizable by QT. The mystery to me now is how come the encoding process just went on and on.Īnyway Judy,Judy.ooops, I mean JulieJuilieJulie, thanks. Then I went back to the file and, viola, it played in QT. Then I decided to stop progress and quit ffmpeg (see what was going oon below). What's below is what I started to write, and did post. $ mkvextract timecodes_v2 input.mkv 2:timecodes-track2.txt If you need the timecodes for all the blocks of track 2 from a file then you can let mkvextract create a timecode v2 format file like this: $ mkvextract tracks movie3.mkv -fullraw 1:extracted.mpeg In this case you can use a track flag like this: Sometimes the raw data of a track might even be useful, e.g. $ mkvextract tracks movie2.mkv 1:extracted.rm 3:extracted.rm This is possible for RealMedia files by using the same output name for those tracks that you want to end up in the same file: Let’s further assume you want only need the video and the RealAudio track but both in the same output file. The identification output might look like this: Let’s assume you have a Matroska file with one RealVideo v10 track, one Vorbis audio track and one RealAudio (COOK) track. $ mkvextract tracks movie.mkv 3:audio.ogg 4:subtitles.srtĪnother example. Track ID 1: video (V_MS/VFW/FOURCC, DIV3) So first fire up mkvmerge with the -identify option: Let’s assume you’ve made a Matroska file with one video track, two audio tracks and two subtitle tracks, and you need the second audio track and the first subtitle track. The extraction to other formats (v1 and v3) is not supported. Timecodes are first sorted and then output as a timecode v2 format compliant file ready to be fed to mkvmerge. Alternatively a stripped-down version can be output in the simple OGM style format. This format is the same that mkvmerge supports for reading chapters. No conversion whatsoever is done.Ĭhapters are converted to a XML format. This format is the same that mkvmerge supports for reading tags.Īttachments are written to they output file as they are. SSA and *** text subtitles will be written as SSA/*** files respectively. Simple text subtitles will be written as SRT files. Please note that due to Matroska’s limited timecode precision the extracted file’s header will be different regarding two fields: data_length (the total number of samples in the file) and the CRC. TrueAudio tracks are written to TTA files. RealAudio tracks are written to RealMedia files. Vorbis audio will be written into an Ogg/Vorbis file. ![]() The ADTS headers will not contain the deprecated emphasis field. Raw PCM data will be written to a WAV file.Īll MPEG2 AAC files will be written into an AAC file with ADTS headers before each packet.Īll MPEG4 AAC files will be written into an AAC file with ADTS headers before each packet. ![]() These will be extracted to raw MP3 and AC3 files. RealVideo tracks are written to RealMedia files. MP4Box from the GPAC package.įixed FPS video tracks with this CodecID are written to AVI files. ![]() H.264 / AVC video tracks are written to H.264 elementary streams which can be processed further with e.g. The following track types are supported at the moment: The decision about the output format is based on the track type, not on the extension used for the output file name.
