Kostya Shishkov	0b0953baec	proresenc: alpha coding support	12 years ago
Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Anton Khirnov	716d413c13	Replace PIX_FMT_* -> AV_PIX_FMT_*, PixelFormat -> AVPixelFormat	12 years ago
Martin Storsjö	e6153f173a	avopt: Store defaults for AV_OPT_TYPE_INT in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	124134e424	avopt: Store defaults for AV_OPT_TYPE_CONST in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	cc86bd4ccc	proresenc: Don't free a buffer not owned by the codec The data in coded_frame isn't allocated using get_buffer, but is copied from the input frame to the encoder, so we should not try to free it ourselves. This fixes an assert failure when running in debug mode. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	6d9e74cd41	proresenc: Write the full value in one put_bits call Previously, the put_bits call writing the value wrote a value larger than the number of bits specified, failing asserts in debug mode. There was no actual bitstream writer corruption, since the overwritten bit already always was set to 1. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Maksalov Boris	c0f4cf7798	prores: interlaced ProRes encoding Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Boris Maksalov	cee03436e6	proresenc: use the edge emulation buffer Prevents reading past the end of frame buffer. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	12 years ago
Mans Rullgard	1c2c64edac	proresenc: make a variable local to the loop where it is used This moves the mbs_per_slice declaration inside the only loop where it is used. Fixes a dead assignment. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Kostya Shishkov	83632cbb11	proresenc: multithreaded quantiser search	13 years ago
Kostya Shishkov	6acac061ab	prores: allow user to set fixed quantiser	13 years ago
Kostya Shishkov	4db4b53dc8	proresenc: give user a possibility to alter some encoding parameters This allows user to select quantisation matrix from different profile, stamp frames with custom vendor string and change target bitrate.	13 years ago
Kostya Shishkov	12b812d2e5	prores: store and retrieve extended colourspace information Based on the patch by Phil Barrett.	13 years ago
Phil Barrett	c7084182e8	proresenc: correct edge emulation Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Kostya Shishkov	235d693286	prores: handle 444 chroma in right order ProRes codes chroma blocks in 444 mode in different order than luma blocks, so make both decoder and encoder read/write chroma blocks in right order. Reported by Phil Barrett	13 years ago
Christophe GISQUET	b5696ff2b8	prores: use natural integer type for the codebook index The operations that use it require it to be promoted to a larger (natural) type and thus perform sign extension on it. While an optimal compiler may account for this, gcc 4.6 (for x86 Windows) fails. Using the natural integer type provides a 2% speedup for Win64 and 1% for Win32.

Kostya Shishkov	6d702dc072	proresenc: force bitrate not to exceed given limit Apple ProRes Format Specifications mentions target data size for every frame, so make sure frame meets it. This also allows encoder to demand much smaller packet sizes for output.	13 years ago
Kostya Shishkov	17b11ffec7	proresenc: initialise 'sign' variable	13 years ago
Kostya Shishkov	1a265f6187	prores encoder	13 years ago
