NAME
tcdecode - read multimedia streams from medium, decode to raw format and print to standard output SYNOPSIS
tcdecode -i name [ -x codec ] [ -t package ] [ -g WxH ] [ -s c,f,r ] [ -C s-e ] [ -y codec ] [ -Y ] [ -Q mode ] [ -A flag ] [ -d verbosity ] [ -v ] COPYRIGHT
tcdecode is Copyright (C) by Thomas Oestreich. DESCRIPTION
tcdecode is part of and usually called by transcode. However, it can also be used independently. tcdecode 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. tcdecode reads streams from file or from stdin. -g WxH video frame width and height [720x576] -C s-e decode and print out only this frame interval (video) or bytes (audio) [all]. -x codec source codec, if not detected of reading from stdin. This option also specifies video and audio context of the source for decoding. Currently, supported parameter for codec are mp3 MPEG audio (lame) ac3 AC3 audio (liba52) dv Digital Video DV (libdv) mpeg2 MPEG video (libmpeg2) yv12 Y'CbCr YUV mov Quicktime (libquicktime) -t package Currently only argument supported is "lavc". Use the codec by -x from this package. Available (-x) codecs for lavc are: mpeg2, divx3, divx, divx4, mp42, mjpg, rv10, svq1, svq3, vp3, 4xm, wmv1, wmv2, hfyu, indeo3, h263p, h263i -y codec target codec. tcdecode only decodes to raw format suitable for transcode. Valid option parameter for codec are rgb RGB 24bit yv12 Y'CbCr YUV yuy2 4:2:2 YUV pcm SIGNED LE 16bit PCM -s c,f,r audio gain for AC3 downmixing [1.0,1.0,1.0] -Y decoded Digital Video (raw) YUV frame is in YUY2 (packet) format using libdv. Downsample frame to YV12. PAL users should compile libdv with --with-pal-yuv=YV12 to avoid this option [off] -A flag audio flag for AC3/A52 decoder [none]. This flag determines the down-mixing configuration. Valid choices for flag are determined by the following bits set: drc off 1 demux 2 dolby off 4 Add those numbers to turn multiple options on. -Q mode decoding quality. Certain codecs, e.g., DV with libdv allow for changing this parameter if speed is prefered over quality. Valid parameter are 1=fastest-5=best [5]. -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. NOTES
tcdecode is a front end for decoding various sources and is used in transcode(1)'s import modules. EXAMPLES
The command tcdecode -i foo.mp3 -x mp3 decodes an MPEG audio stream and prints raw PCM data to stdout. The command tcextract -i foo.avi -x mp3 | tcdecode -x mp3 extracts an MPEG audio track from the AVI-file foo.avi and pipes the frames into the decoder AUTHORS

NAME
tcprobe - probe multimedia streams from medium and print information on the standard output SYNOPSIS
tcprobe -i name [ -B ] [ -M ] [ -T title ] [ -b bitrate ] [ -H n ] [ -f seekfile ] [ -d verbosity ] [ -v ] COPYRIGHT
tcprobe is Copyright (C) by Thomas Oestreich. DESCRIPTION
tcprobe is part of and usually called by transcode. However, it can also be used independently. tcprobe 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. You can specify a file, directory, device, mountpoint or host address as input source. tcprobe usually handles the different types correctly. -B Binary output to stdout for use in transcode. -M Use EXPERIMENTAL mplayer probe, useful for streams that tcprobe doesn't recognize elsewhere. With this option enabled, tcprobe merely acts as a frontend for mplayer; of course mplayer binary needs to be installed and avalaible somewhere in PATH. -T title Probe for DVD title -H n This option tells tcprobe to scan n MB of input data. Default is to scan 1 MB. To detect all subtitles and audio tracks (if avail- able) it is highly recommended that this n should be at least increased to 10 or even higher. Very often only some audio tracks start during the first MB of a VOB or DVD file so transcode cannot detect them if not called with a higher value. Please note that transcode(1) has a similar -H option as well which has the same meaning. -s n Skip the first n bytes of the input stream. Default is to skip no bytes. -b bitrate Set audio encoder bitrate to bitrate -f seekfile Read index/seek information from seekfile. This is especially useful for AVI files when it takes a long time to probe when there is no index in the AVI available. Also see aviindex(1). -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. NOTES
tcprobe is a front end for probing various source types and is used in transcode's import modules. EXAMPLES
The command tcprobe -i foo.avi will print interesting information about the AVI file itself and its video and audio content. AUTHORS
