What steps will reproduce the problem?
(1) Build Chromium with 'proprietary_codecs = true' and 'ffmpeg_branding = "Chrome"'
(2) Play any MP4 video (MSE or not)
(3) Check chrome://media-internals to make sure GpuVideoDecoder is selected
(4) Perform a seek

[18944:21428:0404/090921.473:FATAL:gpu_video_decoder.cc(854)] Check failed: bitstream_buffers_in_decoder_.empty().
