Hi,
this is re-posting of below message.
http://ffmpeg.org/pipermail/ffmpeg-devel/2017-November/219643.html
I believe the patch format is correct this time around.
In order to encode with low latency in Intel QSV, we need to fix
libavcodec/qsvenc.c like below diff info.
I don't understand why q->async_fifo would be set to q->async_depth "+1".
If you know about that or have any comments or suggestions, please tell me.
Thank you.
