* vp4: prevent unaligned memory access in loop filterPeter Ross2019-10-30
| | | | | | | | | | | | VP4 applies a loop filter during motion compensation, causing the block offset will often by unaligned. This produces a bus error on some platforms, namely ARMv7 NEON. This patch adds a unaligned version of the loop filter function pointer to VP3DSPContext. Reported-by: Mike Melanson <mike@multimedia.cx> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avcodec/vp3dsp: add 10 coefficient version of the VP3 IDCTPeter Ross2019-01-26
| | | | | | This version of the IDCT is used by the VP6 decoder. Signed-off-by: Peter Ross <pross@xvid.org>

| | | | | | This is also used by the VP6 decoder. Signed-off-by: Peter Ross <pross@xvid.org>
* avcodec/mips: [loongson] optimize theora decoding in vp3dsp.gxw2018-12-27
| | | | | | | | | | | | | | Optimize theora decoding with msa in functions: 1. ff_vp3_idct_add_msa 2. ff_vp3_idct_put_msa 3. ff_vp3_idct_dc_add_msa 4. ff_vp3_v_loop_filter_msa 5. ff_vp3_h_loop_filter_msa 6. ff_put_no_rnd_pixels_l2_msa Theora decoding speed improved about 36%(from 22fps to 30fps, Tested on loongson 2K1000).

|\ | | | | | | | | | | | | * commit '6892df9294d93322d43255ada299507465bc93c8': vp3: Change type of stride parameters to ptrdiff_t Merged-by: Clément Bœsch <u@pkh.me>
| * vp3: Change type of stride parameters to ptrdiff_tDiego Biurrun2016-08-26
| | | | | | | | | | | | | | This avoids SIMD-optimized functions having to sign-extend their stride argument manually to be able to do pointer arithmetic. Also adjust parameter names to be "stride" everywhere.

| * Remove all Blackfin architecture optimizationsDiego Biurrun2014-06-02
| | | | | | | | | | | | Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.
| * vp3: Use full transpose for all IDCTsRonald S. Bultje2013-04-15
| | | | | | | | | | | | | | | | | | | | | | This way, the special IDCT permutations are no longer needed. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Also remove the unused type == 0 cases from the plain C version of the idct.

| | | | | | | | | | | | | | | | This way, the special IDCT permutations are no longer needed. Bfin code is disabled until someone updates it. This is similar to how H264 does it, and removes the dsputil dependency imposed by the scantable code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
