* checkasm: add hscale testJosh de Kock2020-05-15
| | | | | | | This tests the hscale 8bpp to 14/18bpp functions with different filter sizes. Signed-off-by: Josh de Kock <josh@itanimul.li>
* checkasm: add function to check and diff memoryMartin Storsjö2020-05-15
| | | | | | This was ported from dav1d (c950e7101bdf5f7117bfca816984a21e550509f0). Signed-off-by: Josh de Kock <josh@itanimul.li>
* swscale: fix NEON hscale initJosh de Kock2020-05-15
| | | | | | | | | | | | | The NEON hscale function only supports X8 filter sizes and should only be selected when these are being used. At the moment filterAlign is set to 8 but in the future when extra NEON assembly for specific sizes is added they will need to have checks here too. The immediate usecase for this change is making the hscale checkasm test easier and without NEON specific edge-cases (x86 already has these guards). Signed-off-by: Josh de Kock <josh@itanimul.li>
* avcodec/nvenc: use framerate if availableZachariah Brown2020-05-15
| | | | | | | | | | | | The h264_nvenc and hevc_nvenc encoders aren't respecting the framerate in the codec context. Instead it was using the timebase which in our use-case was 1/1000 so the encoder was behaving as if we wanted 1000fps. This resulted in poor encoding results due to an extremely low bitrate. Both the amf and qsv encoders already contain similar logic to first check the framerate before falling back to the timebase.

* avformat/tls_schannel: immediately return decrypted data if availableJan Ekström2020-05-13
| | | | | | | | | | | | | | Until now, we would have only attempted to utilize already decrypted data if it was enough to fill the size of buffer requested, that could very well be up to 32 kilobytes. With keep-alive connections this would just lead to recv blocking until rw_timeout had been reached, as the connection would not be officially closed after each transfer. This would also lead to a loop, as such timed out I/O request would just be attempted again. By just returning the available decrypted data, keep-alive based connectivity such as HLS playback is fixed with schannel.
* avformat/tls_schannel: always decrypt all received dataJan Ekström2020-05-13
| | | | | | | | | | | | | The dec_buf seems to be properly managed between read calls, and we have no logic to decrypt before attempting socket I/O. Thus - until now - such data would not be decrypted in case of connections such as HTTP keep-alive, as the recv call would always get executed first, block until rw_timeout, and then get retried by retry_transfer_wrapper. Thus - if data is received - decrypt all of it right away. This way it is available for the following requests in case they can be satisfied with it.
* pixblockdsp, avdct: Add get_pixels_unalignedMartin Storsjö2020-05-13
| | | | | | | | | | | | | Use this in vf_spp.c, where the get_pixels operation is done on unaligned source addresses. Hook up the x86 (mmx and sse) versions of get_pixels to this function pointer, as those implementations seem to support unaligned use. This fixes fate-filter-spp on armv7.

| | | | | | | | | | | | | | | | | Set DEPRECATED flag to option cabac, replace with coder. The priority logic is: 1. s->coder; then 2. avctx->coder_type; then 3. s->cabac.

| | | | | | Only warn instead. API users can find out which extensions were unavailable by using the enabled_inst_extensions and enabled_dev_extensions fields. This eliminates having to trial-and-error to find which extensions were missing.
* hwcontext_vulkan: use the maximum amount of queues for each familyLynne2020-05-12
| | | | | | | | | | Due to our AVHWDevice infrastructure, where API users are offered a way to derive contexts rather than always create new one, our filterchains, being supported by a single hardware device context, can grow to considerable size. Hence, in such situations, using the maximum amount of queues the device offers can be benefitial to eliminating bottlenecks where queue submissions on the same family have to wait for the previous one to finish.
