[FFmpeg-soc] [soc]: r339 - in eac3: ac3.c ac3.h ac3tab.c ac3tab.h eac3.h eac3_parser.c eac3dec.c ffmpeg.patch

[Justin Ruggles]

First off, I want to let everyone else know that I recommended to Bartek 
to merge his changes with the AC-3 decoder patch since it's not in 
FFmpeg SVN yet.  Once it is, the files here will change accordingly.

Although, you seem to be using an old version of the patch and comparing 
against an old version of FFmpeg.  ac3.c, ac3.h, ac3tab.c, and ac3tab.h 
are already in current SVN.  I don't see any modifications to those, so 
they don't need to be here.

I'll review the actual code separately.  Here is what I think should 
change about the structure.

I think that eac3_parser.c should be merged with eac3dec.c.  It's not 
actually a true AVParser, and the naming conventions you've used could 
be misleading.  Also, I don't think you need eac3.h.  Just put the 
decoding context into eac3dec.c.  It should be ok to add the 
E-AC3-specific #define's to ac3.h.  If it gets to be too much when more 
features are added, then maybe it could be split off to its own header.
