* qatar/master:
Partially merged:flvdec: Allow parsing keyframes metadata without seeking in most cases
  Error out if vaapi is not found
  avio: undeprecate av_url_read_fseek/fpause under nicer names
  libvo-*: Don't use deprecated sample format names and enum names
DUPLICATE  flvdec: Fix support for flvtool2 "keyframes based" generated index
DUPLICATE  libavcodec: Use "const enum AVSampleFormat[]" in AVCodec initialization
  Fix the conversion of AV_SAMPLE_FMT_FLT and _DBL to AV_SAMPLE_FMT_S32.
  Convert some undefined 1<<31 shifts into 1U<<31.
