Leo Izen	40bd65a72a	MAINTAINERS: add my new PGP key Adding my new gpg key that I will be using from now on. This key is ed25519, which is more secure than the old rsa4096. Signed-off-by: Leo Izen <leo.izen@gmail.com>	10 months ago
Clément Bœsch	af509f9957	avcodec/proresenc_anatoliy: do not write into chroma reserved bitfields The layout for the frame flags is as follow: chroma_format u(2) reserved u(2) interlace_mode u(2) reserved u(2) chroma_format has 2 allowed values: 0: reserved 1: reserved 2: 4:2:2 3: 4:4:4 interlace_mode has 3 allowed values: 0: progressive 1: tff 2: bff 3: reserved 0x80 is what we expect for "422 not interlaced", and the extra 0x2 from 0x82 is actually writing into the reserved bits.	10 months ago
Clément Bœsch	21f7a814ea	avcodec/proresenc_anatoliy: do not write into alpha reserved bitfields This byte represents 4 reserved bits followed by 4 alpha_channel_type bits. alpha_channel_type currently has 3 differents defined values: 0 (no alpha), 1 (8b alpha), and 2 (16b alpha), all the other values are reserved. The 4 initial reserved bits are expected to be 0.	10 months ago
Clément Bœsch	6d35911667	avcodec/proresenc_kostya: do not write into alpha reserved bitfields This byte represents 4 reserved bits followed by 4 alpha_channel_type bits. alpha_channel_type currently has 3 differents defined values: 0 (no alpha), 1 (8b alpha), and 2 (16b alpha), all the other values are reserved. This part is correctly written (alpha_bits>>3 does the correct thing), but the 4 initial bits are reserved.	10 months ago
Clément Bœsch	aa7ccd0ce9	avcodec/proresenc_kostya: use a compatible bitstream version Quoting SMPTE RDD 36:2015: A decoder shall abort if it encounters a bitstream with an unsupported bitstream_version value. If 0, the value of the chroma_format syntax element shall be 2 (4:2:2 sampling) and the value of the alpha_channel_type element shall be 0 (no encoded alpha); if 1, any permissible value may be used for those syntax elements. So if we're not in 4:2:2 or if there is alpha, we are not allowed to use version 0.	10 months ago
