[FFmpeg-cvslog] Only test the first frame for missing aac_adtstoasc bistream filter.

[Carl Eugen Hoyos]

ffmpeg | branch: release/1.0 | Carl Eugen Hoyos <cehoyos at ag.or.at> | Tue Mar 26 15:16:07 2013 +0100| [fe995dcd84c6e2aca3216a10a996ecfbba964b6c] | committer: Carl Eugen Hoyos

Only test the first frame for missing aac_adtstoasc bistream filter.

Many players ignore broken aac frames, so don't abort mov or flv
muxing when encountering one, just print a warning instead.

Fixes ticket #2380.
(cherry picked from commit 1741fece7073f51efdd837a4f307ea2cdf3d1cfb)
