Bug 30462 – MediaPlayer doesn't set properties on new privates

• Status: RESOLVED
• Resolution: FIXED
• Component: Media

[Benjamin Otte]

When constructing a new MediaPlayerPrivate object, the MediaPlayer does not set properties like rate, volume, visible on the private instance, so the instance will use default values, which might be wrong.

I'm not sure what the best way to handle them is - add them to the constructor of the private objects or provide a getter on the MediaPlayer objects so the privates can just query them?
I'm also not sure what the best way to test this is since the MediaElement doesn't know that the private has wrong values.

[Benjamin Otte]

I'm just seeing there is getters already, so it looks like this is only an issue with the GStreamer elements.

Agreed, it is the responsibility of the media engine to query the element's state when it is instantiated.

You could take the oportunity to fix this weird space here =).

You should use static_cast<double>() here, mind the space.

These changes look unrelated, can they go in a separate patch?

Just so it's crystal clear: this is being removed because the mute logic is already handled by HTMLMediaElement? I'll say r- mainly because of the unrelated changes above, but otherwise looks fine to me, so should be good to land after fixing the nits.

Here's an updated patch. Sorry about the cairo_paint() - I'll file a separate bug for that.

I've had a look and setMuted() is gone from the other MediaPlayerPrivate implementations. The HTMLMediaElement takes care of it these days.

This failure looks unrelated.  Not sure what's going on yet.

It's a real failure, but not your fault.  The bots are just way behind.  bug 30098.
