Does the Windows 7 computer stream at the full 25fps when stream-copying
from the camera to youtube?
You could try streaming the .mkv file to youtube from a different Windows 7
computer, and see if that works. Maybe will help narrow down if it's
Youtube, your ffmpeg command, or your computer.
Personally, I used to stream to youtube with Windows 10, but switched to
Ubuntu because there's less extra stuff included with the OS, etc. Just
seems simpler. I'm streaming 6 cameras to youtube now from one Ubuntu
computer and it's really stable.
