From: Haihao Xiang <haihao.xi...@intel.com> This allows a downstream element stores more frames from VAAPI decoders and fixes the broke cases for the driver/hardware combination which doesn't rely on fixed surface-array.
For example: $ ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi \ -i input.mp4 -c:v hevc_vaapi -f null - ... [h264 @ 0x557a075a1400] get_buffer() failed [h264 @ 0x557a075a1400] thread_get_buffer() failed [h264 @ 0x557a075a1400] decode_slice_header error [h264 @ 0x557a075a1400] no frame!
