Martin Storsjö	aa0dd52434	xxan: Disallow odd width Decoded data is always written in pairs within this decoder. This fixes writes out of bounds. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

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. CC:libav-stable@libav.org	12 years ago

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.	13 years ago
Reimar Döffinger	371e165443	Try to set AVFrame.reference to correct values. I am not sure these new values are correct, not am I sure the semantics are a good idea since we do not seem to make any use of them but they caused a lot of confusion, but this seems to make things closer to matching the documentation.
