James Almer	13b1bbff0b	avcodec: deprecate Lossless and Intra Only encoder capabilites Both are codec properties and not encoder capabilities. The relevant AVCodecDescriptor.props flags exist for this purpose. Signed-off-by: James Almer <jamrial@gmail.com>	5 years ago

Paul B Mahol	d64cbd4fda	remove CHAR_MIN/CHAR_MAX usage It is not needed at all.	5 years ago
Andreas Rheinhardt	198081efb7	avcodec/proresenc_anatoliy: Fix invalid left shift of negative number This fixes ticket #7997 as well as the vsynth-prores_# FATE-tests (where ranges over { 1, 2, 3, _lena } and # over { , _int, _444, _444_int }). (Given that prev_dc is in the range -0xC000..0x3FFF, no overflow can happen upon multiplication with 2.)

Martin Vignali	ff3b4f91cd	avcodec/prores_aw : add support for prores 444 with alpha only 16b alpha is supported (not 8 bits) following official encoder, alpha data doesn't impact yuv plane quality. So the alpha data encoding is done after the yuv part. It's also avoid to loose quality in yuv part when alpha is not uniform. the alpha encoding funcs is mainly take from prores_ks encoder, except for the alpha data reorganization	6 years ago

Martin Vignali	105891cd58	avcodec/prores_aw : change src pix_fmt and alpha description use b64a as src pix fmt (doesn't seems to have an impact on decoding) but it's the value use by official encoder	6 years ago

Dyami Caliri	50833c9f7b	Fix buffer_size argument to init_put_bits() in multiple encoders. Several encoders were multiplying the buffer size by 8, in order to get a bit size. However, the buffer_size argument is for the byte size of the buffer. We had experienced crashes encoding prores (Anatoliy) at size 4096x4096.	10 years ago

Michael Niedermayer	b3c3996212	avcodec: rename prores encoders Using the first names of authors sounds somewhat unprofessional and might be considered offensive which is not intended. The new names use the initials of the authors due to simplicity and the possibility to apply it consistently without the need to find political correct names for each future case where alternative codecs might exist. Also its shorter ... If someone has a better idea, like maybe 2 random letters and people prefer it then iam happy to switch to that ...
