What steps will reproduce the problem?
1. You need VP9 SVC enabled in browser and a player able to play back the attached RTPDump to the browser in a loop.

What is the expected result?
Video stream should be displayed without errors.

What do you see instead?
"Aw snap" when the attached video is played back the 2nd time.

What version of the product are you using? On what operating system?
e. g. Chrome 68.0.3409.2 (Official Build) dev (64-bit) on Windows 10

Please provide any additional information below.
Browser crashes with "Aw snap" sporadically when switching between VP9 SVC video streams in an external switcher.
I'm able to reproduce the crash if I play the attached RTPDump video twice.
The first repeated packet crashes the browser here:

void RtpFrameReferenceFinder::FrameReceivedVp9(uint16_t picture_id,
                                               GofInfo* info) {
  int last_picture_id = info->last_picture_id;
  size_t gof_size = std::min(info->gof->num_frames_in_gof, kMaxVp9FramesInGof);

gof seems the be null.
