I would try removing both repositories, downgrading everything to

hth& regards,

Thanks for the repositories Carl. It looks like I may have run into a cinelerra bug new in cinelerra-2.1.5cv20110222-1.pm. I have been able to render my video with both mpeg2enc and ffmpeg, but only using:

ffmpeg -f yuv4mpegpipe -i - -y -target ntsc-dvd -f mpeg2video %

will allow ffmpeg to work. Using 'dvd -ilme -ildct -hq' fails with the int YUVStream:: write_frame(uint8_t**):write_frame() failed:system error (failed read/write) error.

The problem I am having (on both openSuSE and Arch) is that the rendered video (.m2v files) is garbage, see:

I just talked with the cinelerra devs and tested exporting the video as 'raw dv' which worked fine, so there is something wrong with either the defaults in cinelerra or in ffmpeg itself. The video I'm working with is digital video which for some reason will not render even though it plays perfectly in cinelerra. So I'm still stuck at the render stage. I was able to render the collection of stills I had with both mpeg2enc and ffmpeg - both fine.

Cinelerra is a fantastic editor, so I'm motivated to get the rendering to work. No to figure out how to encode it with ffmpeg from the cli...
