* 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: ARM optimised decode_block_coeffs_internalMans Rullgard2011-02-11
| | | | | | Approximately 5% faster on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>
* VP8: optimized mv prediction and decodingJason Garrett-Glaser2011-02-10
| | | | | Merge find_near_mvs and mv bitstream decoding: don't do prediction steps until absolutely necessary.
* VP8: idct_mb optimizationsJason Garrett-Glaser2011-02-08
| | | | Currently uses AV_RL32 instead of AV_RL32A, as the latter doesn't exist yet.
* VP8: slightly faster loopfilter sharpness logicJason Garrett-Glaser2011-02-04
|
* VP8: faster deblock strength calculationJason Garrett-Glaser2011-02-04
| | | | Convert hev_thresh logic to a LUT, simplify mbedge_lim calculation.
* VP8: faster filter_level clipJason Garrett-Glaser2011-02-03
|
* VP8: simplify lf_delta mb mode logicJason Garrett-Glaser2011-02-03
|
* VP8: merge chroma MC callsJason Garrett-Glaser2011-01-31
| | | | | Adds some duplicated code, but avoids duplicate edge checks and similar. ~0.5% faster overall on Parkjoy test sample.
* Slightly simplify VP8 inter_predictJason Garrett-Glaser2011-01-30
| | | | Merge an if and a switch.
* Move ff_emulated_edge_mc() into DSPContext.Ronald S. Bultje2011-01-28

* Fix VP8 aliasing problems.Ronald S. Bultje2011-01-28
| | | | Replace * (uint32_t *) buf accesses with AV_WN32A/AV_COPY32.
* 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.

| | | | | | av_check_image_size() instead. Originally committed as revision 24711 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: fix bug in prefetchJason Garrett-Glaser2010-08-05

* VP5/6/8: eliminate CABAC dependencyJason Garrett-Glaser2010-08-04
| | | | | | | Create a custom table for VP5/6/8's renorm to avoid depending on H.264's. Saves one instruction in the arithmetic decoder as well. Originally committed as revision 24701 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: partially inline decode_block_coeffsJason Garrett-Glaser2010-08-04
| | | | | | Avoids a function call in the case of empty DCT blocks (most of the time). Originally committed as revision 24691 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix 100L in r24689Jason Garrett-Glaser2010-08-04
| | | | | | Accidentally committed some timing code. Originally committed as revision 24690 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: simplify decode_block_coeffs to avoid having to track nonzero coeffsJason Garrett-Glaser2010-08-04
| | | | | | Slightly faster. Originally committed as revision 24689 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: slightly faster DCT coefficient probability updateJason Garrett-Glaser2010-08-03

* VP8: eliminate a dereference in coefficient decodingJason Garrett-Glaser2010-08-02
| | | | Originally committed as revision 24671 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: much faster DC transform handlingJason Garrett-Glaser2010-08-02
| | | | | | | | | | A lot of the time the DC block is empty: don't do the WHT in this case. A lot of the rest of the time, there's only one coefficient: make a special DC-only transform for that case. When the block is empty, don't incorrectly mark luma DCT blocks as having DC coefficients. Originally committed as revision 24670 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: move zeroing of luma DC block into the WHTJason Garrett-Glaser2010-08-02
| | | | | | | Lets us do the zeroing in asm instead of C. Also makes it consistent with the way the regular iDCT code does it. Originally committed as revision 24668 to svn://svn.ffmpeg.org/ffmpeg/trunk

* VP8: Inline traversing vp8_small_mvtreeDavid Conrad2010-07-23

* Decode DCT tokens by branching to a different code path for each branchDavid Conrad2010-07-23
| | | | | | | | | | on the huffman tree, instead of traversing the tree in a while loop. Based on the similar optimization in libvpx's detokenize.c 10% faster at normal bitrates, and 30% faster for high-bitrate intra-only Originally committed as revision 24468 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | Also add Ronald to maintainers. Originally committed as revision 24464 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: always_inline some things to force gcc to do the right thingJason Garrett-Glaser2010-07-23
| | | | | | Mostly seems to help in the MC code, which gets a hundred cycles faster. Originally committed as revision 24463 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: use AV_RL24 instead of defining a new RL24.Jason Garrett-Glaser2010-07-23
