* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* 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.

* h264: define FF_PROFILE_H264_HIGH_444 to the correct valueJanne Grunau2011-02-08
| | | | | It was removed in fe9a3fb since it had the wrong value. Add profile name for it.

* Move ff_emulated_edge_mc() into DSPContext.Ronald S. Bultje2011-01-28

* 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>
* Make ff_h264_find_frame_end static to h264.c; delete h264_parser.hDiego Elio Pettenò2011-01-25
| | | | | | | The header is empty after making the function static, so delete it and drop its usage. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>

* Fix crash on resolution change (issue 2393).Ronald S. Bultje2011-01-22
| | | | | | | | Don't free RBSP tables (containing decoded NAL units) on resolution change, because we actually need this data to decode the frame after reiniting (with new resolution). Fixed issue 2393. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
* Remove H.264 encoder fragmentsAlex Converse2011-01-22
| | | | | | | It's incomplete, no one is working on it, and when someone asks about working on it we advise them not to. Signed-off-by: Mans Rullgard <mans@mansr.com>

* H.264/SVQ3: make chroma DC work the same way as luma DCJason Garrett-Glaser2011-01-15
| | | | | | | No speed improvement, but necessary for some future stuff. Also opens up the possibility of asm chroma dc idct/dequant. Originally committed as revision 26349 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Port SVQ3 to use the new mb_luma_dc method of storing luma DC coefficients.Jason Garrett-Glaser2011-01-15
| | | | | | | Doesn't help speed as there isn't an asm implementation yet, but consistency is a good thing. Originally committed as revision 26348 to svn://svn.ffmpeg.org/ffmpeg/trunk
* H.264: Remove useless arg to chroma_dc_dequant_idct_cJason Garrett-Glaser2011-01-14
| | | | Originally committed as revision 26345 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Fix SVQ3Jason Garrett-Glaser2011-01-14
| | | | | | Regression in r26336-7. Originally committed as revision 26341 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Reindent after r26337.Jason Garrett-Glaser2011-01-14
| | | | Originally committed as revision 26338 to svn://svn.ffmpeg.org/ffmpeg/trunk
* H.264: switch to x264-style tracking of luma/chroma DC NNZJason Garrett-Glaser2011-01-14
| | | | | | | Useful so that we don't have to run the hierarchical DC iDCT if there aren't any coefficients. Opens up some future opportunities for optimization as well. Originally committed as revision 26337 to svn://svn.ffmpeg.org/ffmpeg/trunk
* H.264: split luma dc idct out and implement MMX/SSE2 versionsJason Garrett-Glaser2011-01-14
| | | | | | | | | | About 2.5x the speed. NOTE: the way that the asm code handles large qmuls is a bit suboptimal. If x264-style dequant was used (separate shift and qmul values), it might be possible to get some extra speed. Originally committed as revision 26336 to svn://svn.ffmpeg.org/ffmpeg/trunk
* H.264: eliminate non-transposed scantable support.Jason Garrett-Glaser2011-01-14
| | | | | | | | | | It was an ugly hack to begin with and didn't give any performance. NOTE: this patch opens up some future simplifications to be made (such as removing some of the scantables from H264Context) but doesn't take advantage of them yet. Originally committed as revision 26329 to svn://svn.ffmpeg.org/ffmpeg/trunk
* H.264: fix grayscale decoding with explicit wpredJason Garrett-Glaser2011-01-10
| | | | Originally committed as revision 26306 to svn://svn.ffmpeg.org/ffmpeg/trunk
* SVQ3: Allow decoding if thread_count is > 1Alexander Strange2010-12-15
| | | | | | | svq3 still doesn't support multithreading, but it's simpler for clients if they can enable threading for all codecs by default. Originally committed as revision 26015 to svn://svn.ffmpeg.org/ffmpeg/trunk
* In h264 decoder, fix decoding when nal end sequence is presentBaptiste Coudurier2010-11-23

* H.264 decode: support cropping up to 28 pixels in interlaced mode.Reimar Döffinger2010-11-03
| | | | | | | | Contrary to progressive, just being able to crop up to 14/15 pixels is not enough to encode all supported resolutions, and the new behaviour is also consistent with e.g. MPEG-2 etc. Originally committed as revision 25669 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Do not assume PIX_FMT_YUV420P will remain the only supported output format ↵Carl Eugen Hoyos2010-10-05

* Try to fix crashes introduced by r25218Jason Garrett-Glaser2010-09-28
| | | | | | | r25218 made assumptions about the existence of past reference frames that weren't necessarily true. Originally committed as revision 25243 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Improve error concealment of lost framesJason Garrett-Glaser2010-09-27
| | | | | | If a frame is lost, replace it with data from the previous valid frame. Originally committed as revision 25218 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename h264_idct_sse2.asm to h264_idct.asm; move inline IDCT asm fromRonald S. Bultje2010-09-14
| | | | | | | | | | | | | h264dsp_mmx.c to h264_idct.asm (as yasm code). Because the loops are now coded in asm instead of C, this is (depending on the function) up to 50% faster for cases where gcc didn't do a great job at looping. Since h264_idct_add8() is now faster than the manual loop setup in h264.c, in-asm idct calling can now be enabled for chroma as well (see r16207). For MMX, this is 5% faster. For SSE2 (which isn't done for chroma if h264.c does the looping), this makes it up to 50% faster. Speed gain overall is ~0.5-1.0%.

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Move static function fill_filter_caches() from h264.h to h264.c.Diego Biurrun2010-04-13
| | | | | | | | The function is only used within that file, so it makes sense to place it there. This fixes many warnings of the type: h264.h:1170: warning: ‘fill_filter_caches’ defined but not used Originally committed as revision 22876 to svn://svn.ffmpeg.org/ffmpeg/trunk
* H264: Copy h264dsp when creating new slice threadsAlexander Strange2010-03-31

* Move H264 dsputil functions into their own structMåns Rullgård2010-03-16
| | | | | | | | | | | This moves the H264-specific functions from DSPContext to the new H264DSPContext. The code is made conditional on CONFIG_H264DSP which is set by the codecs requiring it. The qpel and chroma MC functions are not moved as these are used by non-h264 code. Originally committed as revision 22565 to svn://svn.ffmpeg.org/ffmpeg/trunk
