No, I didn’t tested it with MacOS.

In my iOS, I’m using this ffmpeg to get the video frame and decoding from UDP and for this
I use avcodec_decode_video2 well under 3.0.5.

Only thing what I need to know is that what make this avcodec_decode_video2 get slowdown
for 3.1 not 3.0.5.

May testing it with ffmpeg -i output be meaningful for this case? In this case we couldn’t check
the delay correctly for avcodec_decode_video2 or avcodec_send_packet.

Thanks.
