Seems like the whole thing about HTML5 and video/audio formats is not done yet, three years after my cursing at Quassel due to qt-webkit because Qt-Webkit decided to bring in GStreamer to support HTML5 video.
This time, the issue is with both Firefox and Thunderbird, both of which come with a webm USE flag that, if disabled, make them fail to build.
I start to wonder, why people insist that for HTML5 compliance you have to support viewing the video? All that you got to do is be able to parse the element and act on it; showing a “This content is not available with your current browser” is quite fine, if I don’t want WebM support!
No technical content for today, it’s Sunday and I’m fighting with getting Thunderbird to work.
