theora - Oct 2009 - ffmpeg2theora 0.25 synchronization issues when converting from .mov

Has anyone noticed this?  I have a video made with Final Cut Pro,  
which I convert to .mov via Compressor.  This .mov file plays back  
fine in Quicktime.  But when I then use ffmpeg2theora to convert to  
ogv, the video seems to play back too fast compared to the audio (I'm  
using VLC 1.0.2, the latest I believe, to play back the ogv file, and  
I also have an app that uses the recently released libtheora 1.1, and  
I see the same sped-up video as with VLC).

I'm wondering if it's a known problem, or if I'm the first to see
this.

I've not seen that and I just re-encoded all my stuff to take advantage 
of 2 pass (using static x86_64 linux bin) - but I have seen audio/video 
issue going from mjpeg to ogv. I solved that issue by importing the 
mjpeg avi into kino and saving as dv and then using ffmpeg2theora.

I assume by .mov you mean h.264 w/ AAC ??

What happens when you export from FCP to mpeg2 and then run 
ffmpeg2theora on that?

For the record, I've not had any problems using older libtheora based 
players on ogv made with latest ffmpeg2theora.

Yes, I have the same problem. I have tested versions 0.24 and 0.25.

Please see thread "[theora] Accelerated video output with ffmpeg2theora
0.24" in the archives of this mailing list.

I have an AVI container with this stream:

    Stream #0.0: Video: rawvideo, yuyv422, 720x576, 25.02 tbr, 25.02 tbn, 25.02

I tried to find a binary of ffmpeg2theora 0.15 for Linux, but all I could find
was ffmpeg2theora-0.15.exe from
http://www.videohelp.com/download/ffmpeg2theora-0.15.exe so I decided to try
with it using Wine.

However, I was not able to convert my test files at all. In the first case no
streams were found and in the second case the video stream was not converted. Am
I missing some options perhaps??? Or is it the Wine?

A Linux binary of 0.15 is available at
http://v2v.cc/~j/ffmpeg2theora/ffmpeg2theora-0.15.linux.bin.bz2. The
URLs seem to follow a predictable pattern, so
http://v2v.cc/~j/ffmpeg2theora/ffmpeg2theora-0.16.linux.bin.bz2 grabs
0.16 for example. A similiar thing can be done for 0.17.

While doubtful that it might have happened, it would regardless be
interesting to know if there was any difference in the output from the
Linux and Windows binaries.

The output from Linux and Windows binaries were identical. So I could not
convert either of my two test cases with version 0.15.

I may just try to install Quicktime 7 on Snow Leopard and go back to  
using the Xiph Quicktime Components to do my video conversions.  I  
notice that the last official build is 0.1.9, released on 6/14/2009.   
Is there a more recent build using libtheora 1.1 available?

Nevermind.  Sorry.  I think I found the snapshot.  Latest one does  
have libtheora built into it.

Oops.  Didn't send to the whole mailing list.  Resending.

But I agree - a new release would be a good idea.

Cheers,
