About the FEC restoration issue

[xiuer-1573]

At present, when the data of each P-frame is less than 20 packets, the number of FEC packets is 1, so how to combat the situation that two packets are lost in a video frame? When more than one packet is lost, I found that the effect is good on ALVR, may I ask what is done on the client

I'm not quite sure how the FEC code works. That was inherited from polygraphene/ALVR. I might put my hands on it soon (moving it to Rust) and so I might have a chance to study it.
