Bug 45101 – [GStreamer] ::buffered() should return multiple ranges in some cases

• Component: Media
• Status: RESOLVED FIXED

[Philippe Normand]

If on-disk buffering is enabled and if the user seeks to a non-downloaded region, the ::buffered() result should reflect this by returning more than one timerange.

This bug highly depends on https://bugzilla.gnome.org/show_bug.cgi?id=623121

Not marked for review yet, I should write a layout test and probably wait the GStreamer features needed by this patch are released ;)

Looks good overall. I'd just recommend doing the check for having exactly 2 buffered ranges, like we discussed on IRC.

> +            rangeRect.setLocation(IntPoint(trackRect.x() + (start / mediaDuration)* totalWidth , trackRect.y()));

I believe you should not need the parens here, or else put the multiplication inside it, any of them would make the code more obvious to me. Also, there's a rogue space before the ',' =)

This is a bad idea.  Please don't do this.

Unless mod_bw comes installed in a normal Apache distribution, you're asking that *every* webkit developer install mod_bw in order to run the layout tests.

This is not acceptable.

I don't think mod_php comes with normal Apache distribution and still we require it.

Oh well at least on Debian apache2.2-common depends on libapache2-mod-php5 ... So, I'll have a look at automagically download mod_bw with the auto-install stuff like you suggested..

Why is mod_bw necessary for this?  Couldn’t a similar result be achieved by having a script feed up the file in the desired manner?

A discussion on the mailing list led us in this direction - Philippe is working on getting this done with a cgi that is already in use today as a base instead.

Note: Gstreamer core and plugins-base 0.10.31 have been released. Bots might need an update of these packages when this patch lands or the test will fail.

[Philippe Normand]

Ok the bots have been upgraded to latest GStreamer packages! :) Can we give this patch a shot Gustavo?
