If you’re delivering audio and video separately the blocking is irrelevant for needing to solve synchronization. That’s why some amount of buffering (a few frames of video at least) on the receiver is needed to hide the jitter between packets / make sure you have the video. You can go super low latency with no buffering but then you need to drop out video / audio when issues occur and those will be visible as glitches - depends on how good your network is.
