Too late for a fix for 53. We might still be able to take a patch for 54.

Comment 3

[Gerry Chang [:gchang]]

This is too late for 54 and it's not a new regression. Mark 54 won't fix.

Comment 4

[Gyula Palko[:gpalko]]

This issue is still reproducible on Nightly 64.

Bug 1490971 got closed as I was looking at it. I'll post the log I got so far. It starts as the seek completes and ends at the first sight of a video demuxing error.
