Bug 113107 – [WK2][GTK] MiniBrowser won't display video controls in <embed> tag

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKitGTK

[Philippe Normand]

Linked page displays fine in ephy/wk1 but nothing in ephy/wk2, the plugin process successfully scans the NPAPI Totem plugins though.

[Philippe Normand]

In my ephy/wk2 about:plugins page I can see a plugin handling video/divx so it should be used.

I can see the totem player, but not the media controls, it seems like the clip rectangle is wrong.

Patch

I'm not sure this patch fixes this bug because the summary and description are a bit confusing to me. The summary says the video doesn't play and the description says nothing is shown. I can see the totem window in MiniBrowser, but the media controls are not rendered because it's clipped. With this patch, the right clip region is used and I can see the media controls and play the content (content doesn't really play for me because I don't have the required codecs for the test case, though)

Looks good to me.

The issue I have here is that the PluginProcess crashes:

The parameters and mimetype are correctly passed to NPP_New, I'd need a debug build to continue to investigate this further...
