[FFmpeg-devel] [PATCH V7 0/3] enable multi-slices in vaapi_h264/265 encoder

[Jun Zhao]

V7: - Fix h264 first_mb_in_slice setting issue. (root cause by Mark)
    - Refine the error handle

V6: - Use rectangular slices and refine the code.

V5: - In h265_vaapi encoder, when setting slice number > max slice number
      supported by driver, report error and return. Same as h264_vaapi.
    - Clean the logic when setting first_slice_segment_in_pic_flags.
  
V4: - Change the array malloc function.
    - Clean the pointless condition check when free the memory.

V3: - Making pic->slices be VAAPIEncodeSlice* instead of VAAPIEncodeSlice**. 
    - Fix resource (vaBuffer) lead when realloc pic->param_buffers fail. 
    - Adjust max_slices location in VAAPIEncodeContext. 
    - Re-work distributing the macro-blocks for multi-slices function.
 
V2: - Change the slice/parameter buffers to dynamic alloc and split the mutil-slice support for AVC/HEVC.

Jun Zhao (3):
  lavc/vaapi_encode: Add max slices number query.
  lavc/vaapi_encode_h264: respect "slices" option in h264 vaapi encoder
  lavc/vaapi_encode_h265: respect "slices" option in h265 vaapi encoder
