Ronald S. Bultje	4ffe5e2aa5	huffyuv: add padding to classic (v1) huffman tables. We slightly overread the input buffer, so we require padding at the end of the buffer, as is documented in the get_bits API. Without padding, we'll read uninitialized data or beyond the end of the .rodata, which may crash. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Justin Ruggles	560f773c7d	avcodec: change number of plane pointers from 4 to 8 at next major bump. Add AV_NUM_DATA_POINTERS to simplify the bump transition. This will allow for supporting more planar audio channels without having to allocate separate pointer arrays.	13 years ago

Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Stefano Sabatini	01042d4123	lavc: set defaults in internal codec frames This is required specifically for setting frame->format to -1, otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading the format from the output decoded frame will get misled. In particular fix regressions occurring with the pending vsrc_buffer patch.	14 years ago
