Unfortunately I have to correct something I wrote in my earlier message. It seems that Monty's patched version of cinelerra has trouble with some of my mpeg2 files, that were correctly handled by the "original" cinelerra (from git://git.cinelerra.org/j6t/cinelerra.git) : some frames at the beginning and at the end of the video are blank (black) and framerate is not correctly detected.

I could build your patched version of cinelerra after applying two other patches from my distribution (Archlinux), which is using gcc-4.5 and libpng-1.4 : http://repos.archlinux.org/wsvn/community/cinelerra-cv/trunk/cinelerra-gcc45.patch http://repos.archlinux.org/wsvn/community/cinelerra-cv/trunk/libpng14.patch The build was successful with included ffmpeg but also with a recent external ffmpeg version (SVN-r23619). The program built with included ffmpeg complained about missing shared libraries. I got it running after : # cd /usr/lib # ln -s libavcodec.so.52 libavcodec-cinelerra.so.52 # ln -s libswscale.so.0 libswscale-cinelerra.so.0 # ln -s libavutil.so.50 libavutil-cinelerra.so.50 # ln -s libavformat.so.52 libavformat-cinelerra.so.52 (But I don't know if it's a good idea.) I tried both versions (included ffmpeg / external ffmpeg) with mpeg2 and AVCHD footage from my camcorder. With mpeg2 no problem, and I had also partial success loading and editing directly AVCHD files (the "original" cinelerra-cv crashed when I tried to load them, so your patched version is much better) : - cinelerra can now open and edit AVCHD files, - but some frames at the beginning and at the end of these clips are not displayed correctly in the viewer/compositor, and also not rendered correctly. It seems that cinelerra with included ffmpeg processes AVCHD slightly better than with external ffmpeg. In both cases the terminal is full of messages like : [swscaler @ 0x7f3657abd590]No accelerated colorspace conversion found from yuv420p to rgb24. [h264 @ 0x7f3625ce6c40]number of reference frames exceeds max (probably corrupt input), discarding one [h264 @ 0x7f3625ce6c40]Cannot parallelize deblocking type 1, decoding such frames in sequential order With external ffmpeg, the first and last frames of a clip are black or look like video noise when they're rendered. With internal ffmpeg, same problem but more frames are displayed/rendered properly. I know AVCHD is not a good format for editing, so problems with it are not really relevant. I just report them as testing results.

I've also needed to fix a few bugs in ffmpeg itself. In order to disseminate the patches a bit more seamlessly, I've put up a copy of my working GIT repository for now: http://git.xiph.org/?p=users/xiphmont/cinelerraCV.git;a=summary The goal is to continue debugging and see this rolled into mainline, so this is not intended to be a permanent source. But it will be around for a while. I've also stashed the individual patches to date at: http://people.xiph.org/~xiphmont/cinelerra/patches/ Monty _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
