Carl Eugen Hoyos	2828f5b0d8	lavc/r210enc: Fix undefined behaviour encoding r10k. Fixes the following ubsan error: libavcodec/r210enc.c:69:28: runtime error: left shift of 522 by 22 places cannot be represented in type 'int' Fixes ticket #7982.	6 years ago
Paul B Mahol	3d8d8c7199	avcodec/r210: use correct pixel format	6 years ago
Tobias Rapp	205b8fd078	avcodec: estimate output bitrate for uncompressed video codecs Allows to get a more realistic total bitrate (and estimated file size) in avi_write_header. Previously a static default value of 200k was assumed. Adds an internal helper function for bitrate guessing.

Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Clément Bœsch	546d69eb43	avcodec: use av_frame_free() for coded_frame	10 years ago
Reimar Döffinger	035180901d	r210enc.c: Simplify and never store more than 10 bits. The r10k and avrp decoders would previously store 12 bit precision for the blue channel, which is inconsistent and probably not a desirable behaviour. Now the 2 unused extra bits are set to 0. This is possibly not ideal either as RGBA1010102 format has the same layout but stores alpha in these bits, thus explicitly setting them to 1 might be preferable.
