Change RTPVideoTypeHeader to absl::variant and move RTPVideoHeader into its own h/cc file. by philipel@webrtc.org - https://webrtc.googlesource.com/src/+/1a4746a56370c6a1643a420184a5de047feb878f

Predator and CL could not provide any possible suspects.

Using Code Search for the file, "internal/raw_logging.cc" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/f4f0f0e2af28098ac58f8548b13d1a1f46d7c846

mbonadei@ -- Could you please look into this issue.

Thanks!

I don't think https://chromium.googlesource.com/chromium/src/+/f4f0f0e2af28098ac58f8548b13d1a1f46d7c846 is the culprit.

It is more likely that https://webrtc-review.googlesource.com/c/src/+/87561 triggered this error.

Assigning to philipel@ for triaging.
