"Timebase not supported" error in transcoding.
Posted: 01 Apr 2007 00:42
Hello there chaps!
I'm using VLC 0.8.6 on Ubuntu 6.10 Server. It also has ffmpeg installed too.
Basically, I am trying to transcode a divx video file to a mpeg-4 video file and mpga audio and then stream via HTTP.
However, I am hitting a major snag as for some reason, VLC can't seem to encode in MPEG-4.
Here is the log file in question -> here.
However, one specific part, where VLC appears to start to try encoding video this happens:
Can anyone help me figure this out?

This has puzzles me as I have ffmpeg and support for MPEG-4 installed. The only clue to my mind is that it complains that timebase is not supported by mpeg 4 standard and that ffmpeg cannot open encoder.stream_out_transcode debug: creating video transcoding from fcc=`mp4v' to fcc=`mp4v'
