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
