theora - Aug 2009 - Black borders on resized videos

Hi there,

I've been playing around with Beta 2 of ffmpeg2theora, or rather the  
macosx build provided at http://firefogg.org/nightly/

Thanks for all the hard work - its great to see some really noticeable  
improvements.

I have one bug to report: upon resizing (down) all manner of content  
(all h.264, however) I am noticing thin black borders - about 4 or 5  
pixels large, sometimes just on one border, sometimes on more than  
one, and apparently random in the side on which they appear. Besides  
being annoying, the presence of the borders also destroys the feeling  
of 'crispness' of the transcoded video by introducing a fuzzy external  
border.

Is this bug known?

Thanks,
Torrance

P.S. I can provide examples both of the commands given and the  
resulting videos if necessary.

What are you using for a player?  Theora video is required to be at 
sizes that are multiples of 16 pixels.  Videos not at those sizes are 
done by having black borders and the player is supposed to crop the 
video viewing area.  Some players don't support that.

Firefox 3.5 does properly support that - it's a good test case to see if 
it's a player issue or a transcoding issue.
