| | | | | | | | | | | constraint_set5_flag These bits are reserved in earlier versions of the H.264 spec, and some poor hardware decoders require they are zero.

* avfilter/vf_guided: support single inputXuewei Meng2021-06-29
| | | | | | | | | | | | Support single input for guided filter by adding guidance mode. If the guidance mode is off, single input is required. And edge-preserving smoothing is conducted. If the mode is on, two inputs are needed. The second input serves as the guidance. For this mode, more tasks are supported, such as detail enhancement, dehazing and so on.

HDR10+ should be passed to packet side data an stored in the container (mkv) for VP9. This CL is taking HDR10+ from AVFrame side data in libvpxenc and is passing it to the AVPacket side data.

* lavfi/vf_vpp_qsv: fix the time_base for outlinkHaihao Xiang2021-06-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 89ffcd1, the status pts of the output link is set to a value in the input link time base, not in the output link time base when EOF is reached. Usually this pst value is larger than the required one because the output link time base is more greater than the input link time base. When "-vf vpp_qsv,fps" is used, user has to wait a long time for the ending of the pipeline because fps filter output a huge number of frames until the wrong status pts is hit. The issue can be triggered with the command below (use a clip with 1000 frames in this case): $> time ffmpeg -hwaccel qsv -c:v hevc_qsv -i input.h265 -vf "vpp_qsv=w=1920:h=1080,fps=fps=30" -f null - ...

* avcodec/ccaption_dec: Make real-time latency configurablePavel Koshevoy2021-06-18
| | | | | | | | | | | Un-hardcode the 200ms minimum latency between emitting subtitle events so that those that wish to receive a subtitle event for every screen change could do so. The problem with delaying realtime output by any amount is that it is unknown when the next byte pair that would trigger output will happen. It may be within 200ms, or it may be several seconds later -- that's not realtime at all.
