[PD] [GEM] pix_film mjpeg crash
hi, been reading some previous discussions, and it seems like the best codec for pix_film is mjpeg, as in not-cpu-expensive. if i encode my movies with ffmpeg with parameters -an -vcodec mjpeg -sameq pd crashes when trying to open that avi in pix_film. pix_film reports on creation: pix_film:: quicktime support pix_film:: libmpeg3 support pix_film:: libaviplay support there is no error on stderr apart from [pix_film]: opening video-mjpeg.avi with format 1908 [pix_film]: ... [pix_film]: ... [pix_film]: ... socket receive error: Connection reset by peer (104) Segmentation fault if anyone would have an idea how can i make Gem work with mjpeg videos it would be greatly appreciated. l. -- sujet est machinique!

hallo, i had a similar problem with mjepeg movies on ubuntu maverick, 1. test if you can play files: lqtplay mjpeg.mov in my case it crashed, 2. my fix: i recompiled libquicktime http://libquicktime.sourceforge.net/ best, alex hi, been reading some previous discussions, and it seems like the best codec for pix_film is mjpeg, as in not-cpu-expensive. if i encode my movies with ffmpeg with parameters -an -vcodec mjpeg -sameq pd crashes when trying to open that avi in pix_film. pix_film reports on creation: pix_film:: quicktime support pix_film:: libmpeg3 support pix_film:: libaviplay support there is no error on stderr apart from [pix_film]: opening video-mjpeg.avi with format 1908 [pix_film]: ...

I have tried the encode just now with the pix_film example.

Re: [PD] [GEM] pix_film mjpeg crash
Oh what I actually wanted to say, are you sure your libquicktime actually supports mjpeg? I am on Gentoo linux here, and my libquicktime is compiled as following : X aac alsa dv encode ffmpeg gtk jpeg mmx opengl png schroedinger vorbis x264 -doc -lame (which basically means I get everything inside beside the documentation (which is mirrored online mostly anyway) and the MP3 encoding support (but I hardly ever use audio in video material)) Unfortunately, I have no clue if Ubuntu has anything similar to this, maybe different versions you can pick from the repository? -- buZz http://puikheid.nl/ ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] [GEM] pix_film mjpeg crash
I've been using mjpeg encoded .avi video and that's worked the best for me with GEM on Ubuntu. However, I highly recommend installing GEM with gmerlin (gavl) support as it drastically sped up playback on my machine. I had to compile it in myself but I think there might be a daily build .deb floating around somewhere. To compile, I got gavl libraries etc. from Roman's PPA https://launchpad.net/~reduzierer/+ppa-packages https://launchpad.net/~reduzierer/+ppa-packages-martin On Sun, Feb 13, 2011 at 5:41 PM, Bastiaan van den Berg b...@spacedout.nlwrote: Oh what I actually wanted to say, are you sure your libquicktime actually supports mjpeg?
