[FFmpeg-devel] [PATCH 0/5] avutil/qsv add hwcontext_qsv

[nablet developer]

added hwcontext_qsv (Intel QuickSync video)
it will handle MFX session initialization and deinitialization,
and will allow to share that code between libavcodec and libavfilter
without adding new API calls for QSV, and also using similar approach
to CUDA & VAAPI
(VPP filter patch is postponded with suggestion to implementa hwcontext_qsv)

nablet developer (5):
  avutil/qsv: move ff_qsv_error function from libavcodec into libavutil,
    because it's going to be shared between libavcodec (existing QSV
    encoders & decoders), libavfilter (upcoming QSV VPP filter) and
    libavutil itself (upcoming hwcontext_qsv implementation). prefix
    changed to avpriv since it's now shared between multiple libraries.
  avutil/qsv: add hwcontext_qsv (QuickSync Video)
  avcodec/qsvdec: use hwcontext_qsv instead of
    ff_qsv_init_internal_session
  avcodec/qsvenc: use hwcontext_qsv instead of
    ff_qsv_init_internal_session
  avcodec/qsv: remove no longer needed functions
    ff_qsv_init_internal_session & ff_qsv_close_internal_session,
    structure QSVSession, since they are now replaced by
    avutil/hwcontext_qsv
