1138790 - Can't seek while in waiting mode

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect, P3)

For this video ms.EndOfStream() isn't called.

When we reach 10s playback, video.waiting is fired. From that point on we can't seek any longer, the spinner will always be shown.

Expected:
When we seek where we have data, spinner disappear and playback resume

bug 1135170 will almost certainly fix this, but we may need a solution for branches.

It's interesting that when I play http://people.mozilla.org/~jyavenard/tests/mse_mp4/bipbop.html?eos=1&eosat=-1&duration=-1&init=0

The same as above, but with EndOfStream() called, if I attempt to seek back to 0, waiting event is fired and again can't start playback or seek from that point on

Bobby, should this be blocking?

If we don't have any reason to believe that it happens a lot in practice on YouTube, I think it's unlikely that we'd want to fix this on spec for YouTube 37.

This does still seem to be a problem even without bug 1135170, so we still do need to look at it.

Jean-Yves - does this issue still exist?

Not this is fixed in the new MSE stack + MediaFormatReader
