  avcodec/libsvtav1: unbreak build with latest svtav1
  
  SVT-AV1 made a change in their public API in 988e930c but without a
  version bump or any other accessible marker, thus breaking ffmpeg build
  with current versions of SVT-AV1.
  
  They have finally bumped versions a month later, so check added.

  ffv1enc_vulkan: disable autodetection of async_depth
  
  The issue is that this could consume gigabytes of VRAM at higher
  resolutions for not that much of a speedup.
  Automatic detection was not a good idea as we can't know how much
  VRAM is actually free.
  Just remove it.

  avformat/hls demuxer: Add WebVTT subtitle support
  
  This add support for WebVTT subtitles in HLS streams.
  Just like for separate audio streams, it supports all available
  WebVTT streams in all renditions.
  No new options are added, it just works and provides subtitles streams
  like any other demuxer.
  The code prevents downloading subtitle segments which are farther
  in the future than the main segments, to avoid loading hundreds
  of subtitle segments in advance.
