Hi! I'm fiddling around a bit with PDP, and it's great! Just one thing: How can I convert my non-mov videos to a pdp_qt-compatible format with a linux-based tool? I've tried, like, all codecs I could think of in ffmpeg without any succes. How do you do it?

VLC is good for converting videos. Check the "Wizard" on the file menu.

hi
since i don't know ffmpeg that much, i can't tell you how to do it with ffmpeg, but i know how with mencoder. from my experience, movies in the mov container and encoded with mjpeg seem to be the most portable ones. mjpeg is a) a simple codec and b) it does only intraframe compression, which is faster to decode and also makes it easier to access frames randomly.
the command line i am using:
mencoder input.<whatever> -o output.mov -nosound -ovc lavc -lavcopts vcodec=mjpeg -of lavf -lavfopts format=mov
not only pdp, but also [pix_film] from Gem and [#in] from gridflow seem to like this format.

hola,
mencoder input.<whatever> -o output.mov -nosound -ovc lavc -lavcopts vcodec=mjpeg -of lavf -lavfopts format=mov
and if you want to play or see youtube videos ( specially thinking here of people who don't have the flash plugin, like those using linux on a ppc ) :
download http://www.arrakis.es/~rggi3/youtube-dl/
and :
youtube-dl http://www.youtube.com/watch?v=AGPZY3GhtWA mencoder AGPZY3GhtWA.flv -o AGPZY3GhtWA.mov -oac pcm -ovc lavc -lavcopts vcodec=mjpeg -of lavf -lavfopts format=mov -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames

which mencoder version do you use for this? i am currently thinking about writing an flv-decoder for pdp for a project. naive re-coding with mencoder always results in intolerable filesizes.

ah i see: MEncoder dev-SVN-rUNKNOWN-4.2.1 (C) 2000-2007 MPlayer Team
which doesn't know the "i_certify_that_my_video_stream_does_not_use_b_frames" option.
probably i should go and read the manual...

yo, the binary releases of mplayer/mencoder are actually quite old. since you seem to use an actual svn checkout, you don't need the option anymore. this option was mandatory to use, when writing into other containers than avi, because lavf was broken for quite a long time and could not handle streams containing b-frames correctly.

Do you know of a quality option in mencoder so that the transcoded filesize stays within reasonable, when we use the vcodec=mjpeg option? ++ O.

Ha ha. An EULA in a command line option?
