11.2% regression in video_WebRtcCamera at 33830001055300000:33900001055400000

I haven't looked too deeply into where and how total_num_frames is calculated, but I browsed through the CLs and picked out a few candidates.

https://webrtc.googlesource.com/src.git/+log/8058fbbd6bc0..448f4d50dc75 (Some CLs related to rate allocation and frame dropping.)
https://chromium-review.googlesource.com/c/chromium/src/+/963642 (Enable GPU memory buffer for video. Not sure if this affects capture, renderer or both.)

Also not sure how much time we should spend on this. https://bugs.chromium.org/p/chromium/issues/detail?id=813522 suggests that total_num_frames isn't a very interestingmetric on it's own.

I don't think any of my commits (which are all about VP9 SVC) could cause this regression.

Downgrading P2s that haven't been modified in more than 6 months, which have no component or owner.

Available, but no owner or component? Please find a component, as no one will ever find this without one.
