[linuxtv-softmpeg] Current libavcodec not source compatible with current softmpeg

[Peter Urbanec <linuxtv.org.dvb@urbanec.net>]

I decided to have a go with libsoftmpeg and am working with current CVS 
versions of most things.

It would appear that on 20-Oct-2003, version 1.236 of avcodec.h in 
ffmpeg changed the definition of aspect ratio from "float aspect_ratio" 
to "AVRational sample_aspect_ratio", presumably to support a more 
precise representation.

Changing the softmpeg code to use the new definition is non-trivial, 
since these changes propagate via "resize_callback" and supporting both 
the old and new representations would probably result in a horribly 
convoluted mess of ifdef code and conversions leading to a further loss 
of precision.

I would like to know what the development policy for softmpeg is in 
terms of which versions of libs are chosen. So far I am finding that I 
can only get softmpeg configured with CVS versions of FusionSound and 
DirectFB, yet CVS version of ffmpeg won't cut it.

Should I downgrade my ffmpeg or provide patches for softmpeg to compile 
with the current CVS version of ffmpeg (breaking source compatibility 
with previous versions of ffmpeg in process) ?
