2014-12-29ff_audio_decoder: add AAC ADTS probing and parsing v2.Torsten Jager
Some MPEG-TS streams dont align ADTS to TS-PES, pad ADTS frames to (nearly) fixed bitrate, and/or wrongly flag all this as LATM. Now the probing is more safe against ambigous input. Somebody please test whether this still breaks real LATM.

Lavc v54,55 seems to ignore request_sample_fmt anyway, but that need not stay that way forever.
2013-10-04ff_audio_decoder: add ATRAC 3 support, and fix some COOK audio trouble.Torsten Jager
I dont wanna lose my early 2000's videoteque. Maybe this needs my upcoming demux_real audio fix for full functionality.

2013-08-10ff_audio_decoder: fix multichannel playbackTorsten Jager
* Observe channel configuration immediately after av_decode_audio* (). Do not try to access nonexistant channels after a 5.1 -> 2.0 switch for example. * Add NULL plane pointer paranoia. * Assume generic channel layout when no detailled one provided. Needed for wma2. * Follow user speaker arrangement changes on the fly. * Defer opening audio out until we have something to play. * Do not reopen audio out with identical settings. This and the previous item should help avoiding waiting on some drivers. * Hard wire output to int16_t. Some of the code did assume that, and we are converting to that anyway. * Do not read sample format from bits_per_coded_sample. Decoders neither alter that field, nor do they force its value to their output. * Rename some vars for better readability.
2013-03-27Reenable MPEG4 audio with fix for failure case.Torsten Jager
Audio out was opened with bogus settings (1Hz != 0) which failed. This prevented a retry after first audio frame came in and corrected the settings (48k/6 channels). Once ao _is_ open successfully, everything works same as before, including further stream conf changes.

2011-08-13ffmpeg audio crash fix (sse2 alignment)Torsten Jager
Certain ffmpeg audio decoders use 32 bit float samples internally (wma, eac3, ...). They are then exported to the calling application as 16 bit integer. That conversion is done by faster sse2 code if your processor supports it. However, sse2 instructions require data buffers to be 16 byte aligned, or hit a segfault otherwise. Plain malloc() / realloc() ensures only 8 byte alignment, giving a 50% chance of a crash. FFmpeg internally uses aligned buffers a lot. It seems to be a good idea to do likewise for input buffers as well, even if current version does not strictly need it yet. Libavutil/av_realloc() has a bug that can break the alignment when enlarging an existing buffer. Thus I included a fixed version of it within ff_audio_decoder.c.

audio channels. So we must keep discarding packets that cannot be used to initialise the codec until we receive one that can be.

This is a backport of the 1.2 code that was commited to utilize the new API provided by FFmpeg for awhile now but this is especially important because the old API has been eliminated all together from said copies of FFmpeg.
