I have been using mplayer from a year old snapshot, and it was playing file
with AAC audio with no problems.
Now I have taken a snapshot from 05_02, and it doesn't recognize input
bitrate, and consumes 100% cpu, possibly for printing error messages.
I am cross compiled on MIPS, FAAD is compiled with fixed point. Here is the
good (old) output, and a new one, plus a media info from the video file.
I created the file with "SUPER" converter.
I can provide any additional info as needed. Please help.
Thanks.
This is good playback:
