>vaapi_encode seems to be using send/receive API, though, and not encode2.
>I see ff_vaapi_encode_receive_packet() -> vaapi_encode_output(), and the former is the callback function used in all vaapi encoders as AVCodec.receive_packet, so this patch in not needed.

Hi James,

vaapi_encode uses encode2 API as well, such as vaapi_h264:

AVCodec ff_h264_vaapi_encoder = {
    .encode2        = &ff_vaapi_encode2,

Whether encoder2 or send_frame/receive_packet, the upper callers are the same avcodec_send_frame/avcodec_receive_packet pair, which calls send_frame/receive_packet if exist, or calls encode2 instead. Please correct me if I am wrong.

And would you please review the other patch "[PATCH v13 1/2] lavc/svt_hevc: add libsvt hevc encoder wrapper" for another time? I have updated it again. Thanks a lot in advance!

Sun, Jing
