Description
Currently, we open ffmpeg io via avio_open2, and then fallback to opening by QFile.
The main reason for the fallback is the ticket https://bugreports.qt.io/browse/QTBUG-122224.
We need to investigate using QFile for all cases.
Some unclear points:
- does avio_open2 handle network protocols that QFile doesn't?
- which buffer size should we set to opening with QFile to ensure the best performance?
