[FFmpeg-soc] [soc]: r1741 - in eac3: ac3dec.c ac3dec.h eac3dec.c

[Bill Crowley]

Justin,

The last compile that worked for me was a couple of days ago, with output
as follows (BTW -- I am unable to get any video output for this particular
sample which shows a video stream recognized as an mpeg2video @ 90000 fps!
Any thoughts on that particular issue would be much appreciated, thanks):

However, when I compiled the changes made to the soc/eac3 directory ealier
today and tried to play the same sample, this is what I got instead:

Because it is an EAC3 audio stream, I of course received the following 
errors:

[liba52 @ 0xa88100]ac3dec: AC3 Source channels are less than specified: 
output to 4 channels.. (frmsize: 896)
[liba52 @ 0xa88100]Error decoding frame
.....

Any suggestions would be appreciated.

Thanks,

Bill.
