Christophe Gisquet	cb530dda7d	utvideoenc: properly set slice height/last line Mimic decoder and obey sampling. Does not affect fate tests for utvideo. Fixes ticket #3949. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Diego Biurrun	c67b449beb	dsputil: Split bswap*_buf() off into a separate context	11 years ago
Michael Niedermayer	637093a2db	avcodec/utvideoenc: skip unused huffman entries This very slightly improves compression Found-by: Christophe Gisquet <christophe.gisquet@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	334aafe565	avcodec/huffman/ff_huff_gen_len_table: support skiping stat=0 entries This is probably not the simplest solution but as this is needed for a bugfix, simplification is left for later. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Carl Eugen Hoyos	c528d833a9	lavc/utvideoenc: Enable frame-threading.	11 years ago
Diego Biurrun	512f3ffe9b	dsputil: Split off HuffYUV encoding bits into their own context Also shorten HuffYUV context member names to avoid clutter.	11 years ago
Michael Niedermayer	0a8c90202b	avcodec/utvideoenc: fix slice_bits size Fixes assertion failure Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Jan Ekström	efec857c9f	utvideoenc: Enable support for multiple slices and use them The official Ut Video decoder only threads with slices, thus until now any files encoded by the libavcodec encoder have only been decodable with a single thread. The default slice count is now set to subsampled_height / 120. Also sets slices to 1 for the Ut Video encoder tests to keep them green.

Jan Ekström	5de64bb34d	utvideoenc: Add support for the new BT.709 FourCCs for YCbCr With cli usage the decoder might have not set the colorspace during encoder init, manual colorspace override might be needed in such cases. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Anton Khirnov	231fd1ed39	utvideoenc/v410enc: do not set AVFrame.reference. That field will be deprecated.	12 years ago
Michael Niedermayer	0fa26bd470	utvideoenc: fix theoretical integer overflow The image sizes needed for this overflow to happen are currently not supported in lavc, thus this should have no effect execpt making the code more robust in light of future changes.

Michael Niedermayer	729b2d02af	utvideoenc: align mangled buffer starts. This is essential for fast SIMD accesses. The same should be done with the predict output. Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	f92f4935ac	utvideoenc: use ff_generate_len() 19% faster smaller files this may also fix possible integer overflows due to previous 32bit useage Tested with libutvideo and our utvideo decoder, this patch does not change decoder output in the test Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
