      avformat/dashenc: only write video streams into HLS master playlist · f7affc6f
      Jian Yang authored 
      Tool mediastreamvalidator reports error "Variant media_[N].m3u8 is
missing audio group" for audio streams in HLS master playlist. As audio
streams are already listed in audio group, skip them as variant media
streams in master playlist.

      lavu/qsv: make a copy as libmfx alignment requirement for uploading · 681aa7d1
      Zhong Li authored 
      Libmfx requires 16 bytes aligned input/output for uploading.
Currently only output is 16 byte aligned and assigning same width/height to
input with smaller buffer size actually, thus definitely will cause segment fault.

Can reproduce with any 1080p nv12 rawvideo input:
ffmpeg -init_hw_device qsv=qsv:hw -hwaccel qsv -filter_hw_device qsv -f rawvideo -pix_fmt nv12 -s:v 1920x1080
-i 1080p_nv12.yuv -vf 'format=nv12,hwupload=extra_hw_frames=16,hwdownload,format=nv12' -an -y out_nv12.yuv

It can fix #7418

      lavu/hwcontext_qsv: Add support for AV_PIX_FMT_BGRA. · a5e1cb9e
      Zhong Li authored 
      RGB32(AV_PIX_FMT_BGRA on intel platforms) format may be used as overlay with alpha blending.
So add AV_PIX_FMT_BGRA format support.

One example of alpha blending overlay: ffmpeg -hwaccel qsv -c:v h264_qsv -i BA1_Sony_D.jsv
-filter_complex 'movie=lena-rgba.png,hwupload=extra_hw_frames=16[a];[0:v][a]overlay_qsv=x=10:y=10'
-c:v h264_qsv -y out.mp4

Rename RGB32 to be BGRA to make it clearer as Mark Thompson's suggestion.

V2: Add P010 format support else will introduce HEVC 10bit encoding regression.
    Thanks for LinJie's discovery.
