pyav version not found

[nanfangxiansheng]

在requirements.txt中的pyav模块下载不对，应当改为av==12.2.0

pip does not have any pyav package, the package name is actually av.
So replace in the requirements.txt file the line pyav==12.2.0 with av==12.2.0
Equivalently: sed -i 's/^pyav==12\.2\.0$/av==12.2.0/' requirements.txt
