NAME
pia - play media files SYNOPSIS
pia [ options ] movie DESCRIPTION
pia is a small X11 tool which playes movie files. OPTIONS
pia understands the usual toolkit options (-geometry + friends). Additional options are: -h display help text -v be verbose. -debug enable debug messages. -dsp <dev> Use OSS device <dev> for sound. -noxv Disable Xvideo extention. -nogl Disable OpenGL. -noaudio Don't play sound. -novideo Don't play video. -slow n Slowdown video playback by factor n. n=2 doubles playback time, ... This also turns off audio playback. SUPPORTED MOVIE FORMATS
Main purpose of this utility is to playback movie files recorded by xawtv, motv and streamer. It should be able to playback every AVI or QuickTime movie written by one of the mentioned utilites. Feel free to submit a bug report if this doesn't work for some file. QuickTime pia uses libquicktime to decode quicktime movies, thus it should be able to decode and playback all movies with codecs supported by libquicktime. AVI AVI support is very limited. Video: uncompressed RGB data (15 and 24 bpp) and mjpeg is supported. Audio: only uncompressed PCM data works. WAV WAV files are playable too, with the same limitation like AVI audio: only uncompressed PCM data. AUTHOR
