* vp8: fix overflow in segmentation map caching.Ronald S. Bultje2011-10-28

* vp8: fix up handling of segmentation_maps in reference frames.Ronald S. Bultje2011-10-21
| | | | | | | | | 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.

* vp8: fix signed overflowsMans Rullgard2011-10-08
| | | | | | | 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>
* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.

* Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 ↵Oskar Arvidsson2011-05-10
| | | | | | | | | | | | | | | | | 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>

* VP8: fix other function declarationJason Garrett-Glaser2011-03-12
| | | | Was missed in 3efbe137.
* VP8: optimize VP8Context struct orderingJason Garrett-Glaser2011-03-12
| | | | | 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.
* VP8: fix function declarationJason Garrett-Glaser2011-03-12

* VP8: use a goto to break out of two loopsJason Garrett-Glaser2011-03-12
| | | | | 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.
* VP8: init one less near_mvJason Garrett-Glaser2011-02-17
| | | | This one didn't actually need to be initialized.

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | 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.

* VP8: idct_mb optimizationsJason Garrett-Glaser2011-02-08

* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Don't do edge emulation unless the edge pixels will be used in MC.Ronald S. Bultje2011-01-25
| | | | | | 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.
