[theora] Ogv file only plays in VLC / Can't be used by most tools.

Fri Apr 30 14:27:24 PDT 2010

Hi,

I'm new here - thanks for having me. (Sorry if I'm in the wrong place or a noob.)

I downloaded the Theora encoder sample (ver 1.1.1), modified it to encode a sequence of bitmaps, and created an OGV file.

The OGV file plays fine in the latest VLC (1.0.5), but I can't do much else with it:

I tried uploading to YouTube, and the video just comes out really corrupt:  http://www.youtube.com/watch?v=sHaMG6mcWu0
I tried using ffmpeg to convert to another format, but it gives errors (listed below).
I tried using MEncoder264 and it failed too. The log is below the FFmpeg log. A potentially useful line of the log is: "Theora header parsing failed: -23"
I also tried using VLC to convert, but it created a zero sized file too.

It seems like the OGV file is bad in some way, but VLC is somehow 'luckily' able to play it.

Does anyone have any suggestions on what might be going on, or how to further diagnose the problem?

I'd like to have a 'more robust' OGV file, which I can easily upload to YouTube or convert to other formats.

In case anyone want's to inspect the OGV file, I've uploaded it here: http://cid-0b8a3e1016031fcd.skydrive.live.com/self.aspx/Public/Out.ogv

Thanks very much for any help,
Mark.
