Video can't be seeked if hosted on Cloudfront with SSL

• Component: Media
• Status: NEW ---

[Zeno Crivelli]

Steps to Reproduce:
-------------------
1) Visit the following link on WebKit Nightly, Safari 5 or 6:
https://d31j8lt3uybmqs.cloudfront.net/temp/midnight_sun_sv1_360p.mp4

2) Quickly seek to a point *ahead* of the buffer

Actual Results:
---------------
Video freezes, sometimes the whole buffer bar disappears and video playback can't be resumed. Other times the buffer bar doesn't disappear but it's frozen, playhead starts to advance for a couple of seconds and then it starts "looping", but in any case video playback is corrupted. 

Expected Results:
-----------------
Video starts loading from the seeked point and playback is resumed automatically, this can be seen by simply changing https:// to http:// in the URL above.

On the one hand this is probably something Amazon should fix, because if the same video is hosted on another server/CDN (with a different SSL certificate) the issue can't be reproduced, but on the other hand this works fine on other browsers (Chrome, IE9, and also with a Flash player), so there is probably an issue to fix in Safari too.

To clarify, are you saying that there is a regression aspect here?

Using Safari 5.1.7, I'm seeing some badness, and some weird behavior, like non-contiguous buffer display in progress track.

I actually tested this on a very old iBook G4 with Tiger and Safari 4.1.3, and I can't reproduce the issue.

So there might be a regression aspect here.

Interesting fact: if I open the source via "Open Location..." in QuickTime Player 10 (on my MacBook Pro running Lion) I can observe the same bug, while if I load it in QuickTime Player 7 (which I've also installed on my MacBook) it works correctly. This seems to explain why there's no issue on Safari 4 on the old iBook G4 (PPC/Tiger) where HTML5 Video - I suppose - is "powered by QuickTime 7" (but correct me if I'm wrong).

Hi,

Is there any news about the status of this issue? I can confirm it (with a screencast if need be).

Would it be possible that at least someone mark it as confirmed so that it might be addressed in a (hopefully) near future?

Thanks very much in advance.

This seems to be fixed now. I'm not able to reproduce the problem anymore (Safari 6.0.2). 

I don't know if you changed something in WebKit or if Amazon changed something on their side... but this is good news.
