Jean-Yves, we're a couple of betas away from RC - what are the options here?  Can you identify a fix?  What's the user impact of backing out 1130450 vs. shipping this regression?
If you back out bug 1130450, these specific MP4s will be not decoded anymore due to a previous regression fixed by bug 1130450. So broken seeking has probably less impact.
How can this be a regression when the video wouldn't have even started or played previously?
I will have a look

Bug 1057879 broke the playback of MP4s with Apple QT extension (no decoding).
Bug 1130450 has fixed this regression, but incompletely: the playback works again but seeking is broken.
This current bug is about broken seeking.

Jean-Yves - Did you have a chance to look into this?

For 37, I tend to agree that the situation has improved even though it it still not working as expected. As we're very late in the 37 cycle, I'm marking this as wontfix for 37.

will work on this today.. hopefully won't take long
You simply can't seek here because doesn't support range request  

Let the video fully buffer, and then you'll be able to seek.

Or host the file to another server that does support range request

BTW, exactly same behaviour with chrome
Untracking since this appears not to be a bug.
