I use 64bit OpebSuSE 11.2 with CV 2.1.
I use high quality JVC footage for a project that consists of tod files.
They are HDV 1920x1080. I converted them first to mpg using the ffmpeg
command:
ffmpeg -i input1.tod -acodec copy -vcodec copy output1.mpg
ffmpeg -i input2.tod -acodec copy -vcodec copy output2.mpg
and so on.
These are put in the timeline. The project settings are:
1920 x 1088
YUVA-8 Bit
Rendering to .m2v using file format YUV4MPEG video with pipe:
ffmpeg -f yuv4mpegpipe -i - -y -r 25 -b 28000000 -f mpeg2video %
Audio to mp3 using file format mpeg audio 384kb/s layer II
Muxing them with the command:
ffmpeg -i rendered.m2v -i rendered.mp3 -vcodec copy -acodec copy output.mpg
gives:

File 'output.mpg' already exists. Overwrite ?
After typing 'y' I get an endless list of errors like these:

There still is an output file but sound and video are not synchronized.
The longer I play it with smplayer, the worse it gets.
I am surprised that even if ffmpeg has been used three time in this sequence:
1. to convert the tod files to mpg files
2. in the render pipe
3. to mux sound and video.
the result is still not OK.
Has anyone experienced this too?
