NAME

       avifix - fix header of AVI-file

SYNOPSIS

       avifix [ -i name [ -F string ] [ -f val1,val2 ] [ -N 0x NN ] [ -b bitrate ] [ -e rate[,bits[,channels]] ] [ -a num ] [ -v ] ]

DESCRIPTION

       avifix fixes the header of an AVI-file with the supplied parameters.

OPTIONS

       -i name
	      Specify the name of the AVI-file.

       -F string
	      Specify the video codec as FourCC.
	      Possible values are RGB, RIFF and TIFF. ???

       -f val1,val2
	      Use this option to change the frame rate and scale information in the header of the AVI-file.  Both values must not be < 0.

       -N 0xnn
	      Use this option to change the audio format identifier in the header of the AVI-file.  Here are some possible values:

	      0x1    PCM uncompressed audio

	      0x50   MPEG layer-2 aka MP2

	      0x55   MPEG layer-3 aka MP3

	      0x2000 AC3 audio

       -b bitrate
	      Use this option to change the encoder bitrate in the header of the AVI-file.  bitrate has to be given in units of kbps.

       -e rate[,bits[,channels]]
	      Use this option to change the audio stream parameters of in the header of the AVI-file.

       -a num Use this option to change the audio stream parameters of audio track number num in the header of the AVI-file.

       -v     Print version information and exit.

EXAMPLES

       The command

       avifix -i my_file.avi -f 30,1

       changes the header of the file my_file.avi and sets the frame rate to 30 fps.

NAME

       tcextract - read multimedia file from medium, extract or demultiplex requested stream and print to standard output

SYNOPSIS

       tcextract
	      -i name [ -x codec ] [ -t magic ] [ -a track ] [ -C s-e ] [ -d verbosity ] [ -v ]

COPYRIGHT

       tcextract is Copyright (C) by Thomas Oestreich.

DESCRIPTION

       tcextract 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.

NOTES

       tcextract is a front end for extracting various raw or encoded audio/video tracks from a source and is used in transcode's import pipeline.

EXAMPLES

       The 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.
