* 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.

* ffbuild: Avoid using the --preprocessor argument to windresMartin Storsjö2021-06-18
| | | | | | | | | | | | | | | | | | | Instead use --preprocessor-arg; in binutils 2.36, the --preprocessor flag was changed so that it no longer accepts a string containing multiple arguments, but the whole --preprocessor argument is treated as the path to the preprocessor executable (where the path can contain spaces). It's currently unclear whether this behaviour will stay or if it is going to be reverted in the future, see discussion at [1]. Just to be safe, avoid using the --preprocessor argument. Don't redeclare the full preprocessing command, but just add the $(CC_DEPFLAGS) options. Based on a patch by Kyle Schwartz.

* dashenc: Write out DASH manifest immediately in streaming modeKevin LaFlamme2021-06-14
| | | | | | | | | | | | | | When streaming mode is enabled with fMP4/CMAF for DASH output, the segment files are available to read by players as soon as the first byte is written instead of only after the file is fully written. The DASH manifest currently only gets written when the final write to the segment file occurs. This means that players cannot stream the first segment while it is being written. When -lhls is enabled with MP4 segments the HLS manifest is written immediately to advertise the in-flight segments. This change adds the same behavior for the DASH manifest so players can stream it immediately.
