  vulkan: use a single command buffer per command buffer pool
  
  We violated the spec, which, despite the actual command buffer pool
  *not* being involved in any functions which require external synchronization
  of the pool, *require* external synchronization even if only the
  command buffers are used.
  
  This also has the effect of *significantly* speeding up execution
  in case command buffers are contended.

  avformat/movenc: fix VVC encoding with leading pictures
  
  The default behavior for VVenC (since v1.10.0) is to create an IDR with
  leading pictures for the first picture in decoding order (POC 32). This
  leads to FFmpeg generating an edit list with an empty entry, skipping
  the leading pictures.
  
  This patch fixes the calculation for the start_pts, while the DTS is
  negative (as produced by vvenc).
