Hendrik Leppkes	f9150c8ac0	lagarith: frame multithreading About 2x speedup going from 1 to 2 threads. 1.7s to 0.85s on foreman CIF. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Ronald S. Bultje	7191e1c490	lagarith: fix color plane inversion for YUY2 output.	13 years ago
Ronald S. Bultje	98d0d19208	lagarith: pad RGB buffer by 1 byte. For left HFYU prediction, we predict from the buffer buf+1 using 8- or 16-byte reads. This means that aligning the buffer by 16 bytes is in itself not sufficient, because if the width itself is 16- or 8-byte aligned, the buffer will not be padded, and thus a read of size 16 at buf+1 will overflow boundaries at the right edge. Padding the buffer by 1 byte is sufficient to not overflow its boundaries. Fixes bug 342.	13 years ago
Kostya Shishkov	464e9ab011	lagarith: add YUY2 decoding support Unlike other variants, for YUY2 we need to use different prediction: * on line 0 for luma we should left predict starting from the second pixel * on line 1 we should left predict first 4 pixels for luma and 2 for chroma * median prediction employed here is taken directly from HuffYUV	13 years ago

Kostya Shishkov	1fdb5649d9	lagarith: make offset array type unsigned This is logical and also fixes checking for the fourth plane offset.	13 years ago
Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Nathan Caldwell	39616fc307	lagarith: Add correct line prediction for RGB Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Diego Biurrun	adbfc605f6	doxygen: Consistently use '@' instead of '\' for Doxygen markup. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Diego Biurrun	f25a2ece76	Drop explicit filenames from @file Doxygen tags. The filename is unnecessary and brittle across file renames.	14 years ago

Anton Khirnov	b2ed95ec48	Replace remaining occurrences of CODEC_TYPE_* with AVMEDIA_TYPE* Tested to compile with lavc major bump. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reimar Döffinger	b0c8b8a69d	Lagarith: fix decoding of one-coloured frames by reading the per-plane color value instead of always taking 0 (resulting in green frames). Fixes issue issue2531. Originally committed as revision 26363 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Carl Eugen Hoyos	d267b339e4	Lagarith decoder by Nathan Caldwell, saintdev at gmail Originally committed as revision 26270 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
