I was banging my head against wall for quite some time - every yuv4mpeg rendering consisted of garbage. Finally, I just rebuilt Cinelerra by disabling external-ffmpeg and now everything is OK. By superficially looking at git's log output (not familiar with git at all) I suspect the problem might be with the following patch: commit 954a91e72bba1ed1ce641b5faee7d4c5f318c074 Author: David Arendt <[email protected]> Date: Sat Dec 27 12:02:20 2008 +0100 Add support for the dnxhd codec. In order to use dnxhd, a recent ffmpeg should be intalled and cinelerra must be compiled with ./configure --with-external-ffmpeg (cinelerra can also be compiled with builtin ffmpeg only dnxhd can't be decoded) Only decoding is handled by this patch. Encoding dnxhd can be done using YUV4MPEG Stream and using the following pipe: ffmpeg -f yuv4mpegpipe -i - -vcodec dnxhd -b 115Mbps %. Remember that dnxhd can not handle every resolution. All tests have been done with 1080p50. Can someone confirm that disabling external-ffmpeg solves the problem?
