[theora] Accelerated video output with ffmpeg2theora 0.24

[Juhani Jaakola]

When I converted two files with ffmpeg2theora their duration changed shorter - they seem to play back with accelerated speed. When I play one of them with VLC, the video stops at 99 seconds but audio continues until 170 seconds. The other file is 120 seconds long but it is played back in 80 seconds.

Here is ffmpeg2theora output:

I have tried with and without options "--optimize --inputfps 25 -F 25", no change.
