Predator and CL could not provide any possible suspects. Using the code search for the file, “frame_loader.cc” assigning to concern owner from GIT revision log. Suspecting Commit# https://chromium.googlesource.com/chromium/src/+/df3ea35f363255ed60698f5e951522beac51c7c0 @dgozman -- Could you please look into this issue, kindly reassign if it has nothing to do with your changes. Thank You.

The repro case fails for me in debug in "avformat_find_stream_info". Interestingly, it does not fail without <video> tag in the attached repro. Could this be a media issue? CC'ing alokp@ and servolk@ who had commits in media/filter in the regression range.
