Aaron Colwell	e02dec25ab	vp8: flush buffers on size changes.	13 years ago
Justin Ruggles	f3a29b750a	avcodec: move some AVCodecContext fields to an internal struct. A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.	13 years ago

Baptiste Coudurier	76741b0e56	h264: 4:2:2 intra decoding support Signed-off-by: Diego Biurrun <diego@biurrun.de> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	ce42a04884	vp8: fix up handling of segmentation_maps in reference frames. Associate segmentation_map[] with reference frame, rather than decoding instance. This fixes cases where the map would be free()'ed on e.g. a size change in one thread, whereas the other thread was still accessing it. Also, it fixes cases where threads overwrite data that is still being referenced by the previous thread, who thinks that it's part of the frame previously decoded by the next thread.	13 years ago

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
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	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	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.

Ronald S. Bultje	44002d8323	Don't do edge emulation unless the edge pixels will be used in MC. Do not emulate larger edges than we will actually use for this round of MC. Decoding goes from avg+SE 29.972+/-0.023sec to 29.856+/-0.023, i.e. 0.12sec or ~0.4% faster.	14 years ago
