Log message:
ffmpeg, ffplay - re-disable optimizations, pending more discussion

Log message:
ffplay4, ffmpeg4: don't disable optimizations.

these are runtime-detected as far as I can see (for multiple archs), so
I don't think there's any harm in enabling them.

bump PKGREVISION.

Log message:
ffmpeg4: add pulseaudio option to enable libpulse support.

With this option and xcb option (for x11grab) I can capture X11 applications
that use pulseaudio by the following ffmpeg4 command options:
% ffmpeg4 -y -f x11grab -video_size 800x600 -r 24 -i :0.0+0,0 \
  -f pulse -i oss_output.audio.monitor -pix_fmt yuv420p capture.mp4
