Comment (by fulinjie):

 Patch has been sent to fix this:
 https://patchwork.ffmpeg.org/patch/13340/

 Previous version of patch and discussion with Mark:
 https://patchwork.ffmpeg.org/patch/13323/

 Media driver will return 2 buffers in fact. The first buffer is
 VACodedBufferSegment
 buffer which includes encoded output. And the second buffer is extra
 VACodedBufferVP9Status.
