Browse can't reproduce html5 video

[manuq]

Environment: XO-1.75, os 13.2.0 build 13 (latest one)

TestCase:

• start Browse
• navigate to ​http://www.quirksmode.org/html5/tests/video.html
• try to play any of the test videos

The sound can be heard, but the video is frozen. The video updates only after several seconds.

I attach two test scripts.

• videoweb1.py opens the testpage mentioned above with WebKit1, the same used by Browse. The same symptoms are shown.
• videoweb2.py tries to use WebKit2, but returns with a segfault. WebKit2 was in development when Fedora 18 was released.

It would be great to check if the WebKit in F20 fixes this. We need an XO build with F20 for that.

Another possibility might be video drivers.

Testing on a xo-4 with 13.3.0 (Au image) with vmeta the examples from ​http://www.quirksmode.org/html5/tests/video.html:

• H264/MP4: video not displayed

• WebM: very slow (may be one frame by second)

• Ogg/Theora: slow, but better than WebM

Thanks. Interesting. 13.2.0-13 does not include VMeta. XO-1.75 performance is quite different to XO-4. Are the VMeta components installed on the XO-1.75 laptop? ​http://wiki.laptop.org/go/Vmeta

Is this a sugar bug? Shouldn't this be on the OLPC bug tracker?

Not until it is proven that it isn't a Browse problem. That can be done by using the WebKit GTK launchers, /usr/libexec/webkitgtk{,3}/GtkLauncher ... if the problem persists, then it isn't Browse, but is instead WebKit, or graphics drivers. Fedora 20 does change all this.

WebKit2 based Browse-200 and later from git does fix this on generic hardware, closing.
