DESCRIPTIONtcextract is part of and usually called by transcode. However, it can also be used independently. tcextract reads source (from stdin if not explicitely defined) and prints on the standard output.
OPTIONS-i name Specify input source. If ommited, stdin is assumed. tcextract reads streams from file or from stdin. -C s-e extract and print out only this frame interval (video) or bytes (audio) [all]. This option is only supported if the source contains proper information to perform a selective extraction. -t magic source file magic. This option is used to identify the source file format if reading is performed from stdin or tcextract fails to identify the source file format. Supported formats are labeled with magic: avi RIFF AVI-file vob MPEG program streams m2v MPEG elementary video stream vdr MPEG digital video recording raw raw bitstream wav RIFF WAVE audio yuv4mpeg mjpeg-tools stream header format -x codec source pdeudo-codec, if not detected when reading from stdin. Currently, supported parameter for codec are mp3 MPEG audio ac3 AC3 audio a52 A52 audio dv Digital Video DV mpeg2 MPEG video yv12 Y'CbCr YUV rgb RGB 24-bit ps1 MPEG private stream (subtitles) pcm raw audio stream -a track extract selected audio or video track from source. -d level With this option you can specify a bitmask to enable different levels of verbosity (if supported). You can combine several levels by adding the corresponding values: QUIET 0 INFO 1 DEBUG 2 STATS 4 WATCH 8 FLIST 16 VIDCORE 32 SYNC 64 COUNTER 128 PRIVATE 256 -v Print version information and exit.
NOTEStcextract is a front end for extracting various raw or encoded audio/video tracks from a source and is used in transcode's import pipeline.
EXAMPLESThe command tcextract -i foo.avi -x mp3 -a 3 extracts MPEG audio track 3 from the AVI-file foo.avi and prints the bitstream to stdout.
