--- Begin Message ---Package: liquidsoap Version: 0.9.2-2 Severity: normal When using liquidsoap to process a Ogg Theora file, the resulting video is full of hickups. I am using this liquidsoap script: set("log.file.path","/tmp/fulltest.log") set("frame.video.channels",1) # http://www.nuug.no/pub/video/frikanalen/1241.ogv = /tmp/input.ogv stream = single("/tmp/input.ogv") output.file.theora(reopen_on_metadata=true, "/tmp/output.ogv",stream) When playing the inputfile with kaffeine, the video flows just fine, but when playing output.ogv, the video hangs for seconds several times. Also, the output file have lost resolution compared to the input file. It seem to have a quarter of the size of the original resolution. -- System Information: Debian Release: squeeze/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing') Architecture: i386 (i686) Kernel: Linux 2.6.32-3-686 (SMP w/2 CPU cores) Locale: LANG=nb_NO.UTF-8, LC_CTYPE=nb_NO.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages liquidsoap depends on: ii adduser 3.112 add and remove users and groups ii libao4 1.0.0-3 Cross Platform Audio Output Librar ii libasound2 1.0.22-2 shared library for ALSA applicatio ii libc6 2.10.2-6 Embedded GNU C Library: Shared lib ii libcamomile-ocaml-da 0.7.2-2 Unicode data for OCaml ii libgavl1 1.1.2-1 low level audio and video library ii libgcc1 1:4.4.2-9 GCC support library ii libjack0 0.118+svn3796-2 JACK Audio Connection Kit (librari ii libmad0 0.15.1b-5 MPEG audio decoder library ii libmagic1 5.04-1 File type determination library us ii libogg0 1.1.4~dfsg-2 Ogg bitstream library ii libpcre3 7.8-3 Perl 5 Compatible Regular Expressi ii libportaudio2 19+svn20071022-3+b1 Portable audio I/O - shared librar ii libpulse0 0.9.21-1 PulseAudio client libraries ii libsamplerate0 0.1.7-3 Audio sample rate conversion libra ii libsdl-mixer1.2 1.2.8-6+b1 mixer library for Simple DirectMed ii libsdl-ttf2.0-0 2.0.9-1 ttf library for Simple DirectMedia ii libsdl1.2debian 1.2.13-5 Simple DirectMedia Layer ii libsoundtouch1c2 1.3.1-2 sound stretching library ii libspeex1 1.2~rc1-1 The Speex codec runtime library ii libstdc++6 4.4.2-9 The GNU Standard C++ Library v3 ii libtagc0 1.6.1-1 TagLib Audio Meta-Data Library (C ii libtheora0 1.1.1+dfsg.1-3 The Theora Video Compression Codec ii libvorbis0a 1.2.3-3 The Vorbis General Audio Compressi ii libvorbisenc2 1.2.3-3 The Vorbis General Audio Compressi ii libvorbisfile3 1.2.3-3 The Vorbis General Audio Compressi ii perl 5.10.1-11 Larry Wall's Practical Extraction ii sox 14.3.0-1.1+b1 Swiss army knife of sound processi ii wget 1.12-1.1 retrieves files from the web Versions of packages liquidsoap recommends: ii logrotate 3.7.8-5 Log rotation utility ii mp3gain 1.5.1-3 Lossless mp3 normalizer with stati ii vorbis-tools 1.2.0-6 several Ogg Vorbis tools ii vorbisgain 0.36-3.1 add Replay Gain volume tags to Ogg Versions of packages liquidsoap suggests: pn faad <none> (no description available) ii festival 1.96~beta-10 General multi-lingual speech synth ii flac 1.2.1-2+b1 Free Lossless Audio Codec - comman pn icecast2 <none> (no description available) pn liguidsoap <none> (no description available) pn mplayer <none> (no description available) -- no debconf information

--- Begin Message ---Source: liquidsoap Source-Version: 0.9.2-3 Hi ! Sorry, I should have commented. The real bug you reported was the video that hangs. It was in fact a wrong bitrate set to 800 when using the quality-based encoding. The problem of the resolution is not a bug bur a feature. The size of the video frames in liquidsoap is a global setting. When processing several video, the resulting output will have a constant size and you have to decide how you want to merge video that have different size. This is also a requirement because we want to be able to manipulate video streams, for instance by merging to video streams. In this case, the merged streams need to have the same size. You can read more online in our documentation: http://savonet.sourceforge.net/doc-0.9.2/video.html The parameters you are looking at are: set("frame.video.width",320) set("frame.video.height",240) set("frame.video.fps",25) Please note that liquidsoap 0.9.2 does not handle frame rate conversion so all video must have the same frame rate. Most of the limitations listed in the above web page are lifted in the current SVN. The video size is still a global parameter, though. If you want to discuss more in detail, you are welcom to join one of our mailing list. Romain
