* swscale/x86/output: add AVX2 version of yuv2nv12cXNelson Gomez2020-06-14
| | | | | | | | | | 256 bits is just wide enough to fit all the operands needed to vectorize the software implementation, but AVX2 is needed to for a couple of instructions like cross-lane permutation. Output is bit-for-bit identical to C. Signed-off-by: Nelson Gomez <nelson.gomez@microsoft.com>
* swscale: make yuv2interleavedX more asm-friendlyNelson Gomez2020-06-14
| | | | | | | | | Extracting information from SwsContext in assembly is difficult, and rearranging SwsContext just for asm access didn't look good. These functions only need a couple of fields from it anyway, so just make them parameters in their own right. Signed-off-by: Nelson Gomez <nelson.gomez@microsoft.com>

* lavf/prompeg: prompeg_write() must report data all was writtenDavid Holroyd2020-06-14
| | | | | | | | | | | | | | | | Previously, prompeg_write() would only report to caller that bytes we written when a FEC packet was actually created. Not all RTP packets are expected to generate a FEC packet however, so this behavior was causing avio to retry writing the RTP packet, eventually forcing the FEC state machine to send a FEC packet erroneously (and so breaking out of the retry loop). This was resulting in incorrect FEC data being generated, and far too many FEC packets to be sent (~100% FEC overhead). fix #7863 Signed-off-by: David Holroyd <david.holroyd@m2amedia.tv>

* avutil/internal: remove FF_ALLOCx{_ARRAY}_OR_GOTO macrosLimin Wang2020-06-13
| | | | | | | | | | | | | | | | | These functions have a terrible design, let us fix them before extending them. First design mistake: no error code. A helper function for testing memory allocation failure where AVERROR(ENOMEM) does not appear is absurd. Second design mistake: printing a message. Return the error code, let the caller print the error message. Third design mistake: hard-coded use of goto. http://ffmpeg.org/pipermail/ffmpeg-devel/2020-May/262544.html Signed-off-by: Limin Wang <lance.lmwang@gmail.com>
