In doing the roll for M60, the following ffmpeg_regression_tests failed:

8 tests failed:

1 test had unknown result:
    FLAKY_Cr100464/FlakyFFmpegRegressionTest.BasicPlayback/0 (../../media/ffmpeg/ffmpeg_regression_tests.cc:386)

However, using the M59 version of ffmpeg resulted in the same failures, so these tests have been broken for a while.

Note that the tests don't produce any ASAN errors, which is good. However, the tests should be fixed (or marked as flaky).
