aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name. 
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

c4f5c2d6f4 Move some mpegaudio functions to new mpegaudiodsp subsystem 
This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

4bac1bbc3b mpegaudio: add _fixed suffix to some names 
This adds a _fixed suffix to the fixed-point versions of things
with both float and fixed-point variants.  This makes it more

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

"Google Summer of Code participation" on the mailinglist.
