Mans Rullgard	bb59156606	vp8: fix signed overflows In addition to avoiding undefined behaviour, an unsigned type makes more sense for packing multiple 8-bit values. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Baptiste Coudurier	231a6df9ea	h264dec: h264: 4:2:2 intra decoding Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 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	3c432e1186	doxygen: Fix documentation for some VP8 functions.	14 years ago
Diego Biurrun	24c9babaaf	doxygen: Fix parameter names to match the function prototypes.	14 years ago
Ronald S. Bultje	9ebcf7699b	vp8: fix segmentation race during frame-threading. Fixes occasional failure of make fate-vp8-test-vector-010 with frame-multithreading enabled.	14 years ago

Mans Rullgard	1550f45a89	Add av_clip_uintp2() function Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Jason Garrett-Glaser	1eeca88691	VP8: optimize VP8Context struct ordering Shaves at least 3KB off code size on x86, should improve cache utilization. This would probably be useful to do for other decoders/encoders as well.	14 years ago

Jason Garrett-Glaser	628b48db85	VP8: use a goto to break out of two loops A break statement was supposed to break out of two loops, but only broke out of one. Didn't affect output, just could have been marginally slower.	14 years ago

Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
