In the documentation on SourceForge...

They list these options:
`-padtop size'
set top pad band size (in pixels)
`-padbottom size'
set bottom pad band size (in pixels)
`-padleft size'
set left pad band size (in pixels)
`-padright size'
set right pad band size (in pixels)
`-padcolor color'
set right pad band size (hex). The value for pad color is expressed as a six digit hexidecimal number where the first two digits represent red, middle two digits green and last two digits blue. Defaults to 000000 (black)
But ffmpeg does not recognize them. What's the story with this? Aren't these implemented? If ffmpeg could do this, it would be the perfect solution to transcoding anamorphic files.

OK, so here's what I found out. Those features were added after 0.4.8, and are available in the current CVS source code. So, I downloaded the code and compiled it.
The padding works beautifully, letterboxing the image and encoding very quickly as ffmpeg does. However, at least when encoding a FILM source, the output was very choppy with duplicated and skipped frames, as if ffmpeg is decoding the wrong ones.
Anyone else working with this?
