* h264: Integrate clear_blocks calls with IDCTRonald S. Bultje2013-04-10
| | | | | | | | | The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

* lavc: stop setting AVFrame.motion_subsample_log2Anton Khirnov2013-03-08
| | | | | It is not used inside lavc anywhere and now it makes no sense to export it.

* h264/svq3: Stop using draw_edgesRonald S. Bultje2013-02-19
| | | | | | | | | | | Instead, only extend edges on-demand when the motion vector actually crosses the visible decoded area using ff_emulated_edge_mc(). This changes decoding time for cathedral from 8.722sec to 8.706sec, i.e. 0.2% faster overall. More generally (VP8 uses this also), low-motion content gets significant speed improvements, whereas high-motion content tends to decode in approximately the same time.

* svq3: unbreak decodingMatti Hamalainen2013-02-18

* h264: deMpegEncContextizeAnton Khirnov2013-02-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | Most of the changes are just trivial are just trivial replacements of fields from MpegEncContext with equivalent fields in H264Context. Everything in h264* other than h264.c are those trivial changes. The nontrivial parts are: 1) extracting a simplified version of the frame management code from mpegvideo.c. We don't need last/next_picture anymore, since h264 uses its own more complex system already and those were set only to appease the mpegvideo parts. 2) some tables that need to be allocated/freed in appropriate places. 3) hwaccels -- mostly trivial replacements. for dxva, the draw_horiz_band() call is moved from ff_dxva2_common_end_frame() to per-codec end_frame() callbacks, because it's now different for h264 and MpegEncContext-based decoders. 4) svq3 -- it does not use h264 complex reference system, so I just added some very simplistic frame management instead and dropped the use of ff_h264_frame_start(). Because of this I also had to move some initialization code to svq3.

* mpegvideo: split ff_draw_horiz_band().Anton Khirnov2013-02-15
| | | | Split out dependency on MpegEncContext.
* svq3: remove a pointless if()Anton Khirnov2013-02-15
| | | | The H264 context is always uninitialized at this point.
* dsputil: Move ff_svq3 function declarations to a separate headerDiego Biurrun2013-02-07

* Drop DCTELEM typedefDiego Biurrun2013-01-22
| | | | | | It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-20
| | | | | | | | Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* svq3: make slice type value unsigned to match svq3_get_ue_golomb return typeJanne Grunau2012-12-09
|
* golomb: use unsigned arithmetics in svq3_get_ue_golomb()Janne Grunau2012-12-08
| | | | | | | | | | This prevents undefined behaviour of signed left shift if the coded value is larger than 2^31. Large values are most likely invalid and caused errors or by feeding random. Validate every use of svq3_get_ue_golomb() and changed the place there the return value was compared with negative numbers. dirac.c was clean, fixed rv30 and svq3.

* h264: disallow constrained intra prediction modes for luma.Ronald S. Bultje2012-02-09
| | | | | | | | | | | Conversion of the luma intra prediction mode to one of the constrained ("alzheimer") ones can happen by crafting special bitstreams, causing a crash because we'll call a NULL function pointer for 16x16 block intra prediction, since constrained intra prediction functions are only implemented for chroma (8x8 blocks).

| | | | | | | | If done before, some parameters aren't known yet. With svq3/rtp, initializing before some parameters are known can lead to calling av_malloc(0), which on OS X currently returns broken pointers.
