Anton Khirnov 8a49d2bcbe xxan: fix invalid memory access in xan_decode_frame_type0()
The loop a few lines below the xan_unpack() call accesses up to
dec_size * 2 bytes into y_buffer, so dec_size must be limited to
buffer_size / 2.

Alex Converse 7181c4edee cosmetics: Remove extra newlines at EOF 2012-01-27 17:19:09 -08:00
Diego Biurrun 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.

Anton Khirnov ec6402b7c5 lavc: use designated initialisers for all codecs.
It's more readable and less prone to breakage.
