WAbstractMedia::setAlternativeContent not used on iPad
In WStreamingVideoWidget, the fallback to MJPEG doesn't work on iPad.
I narrowed it to the followig environment:
- WVideo with 2 sources of different mime types. With the first, the data transfer fails, the second, the mime type is unsupported.
- Safari on iPad iOS 4
- An alternative widget placed using setAlternativeContent
- This alternative widget is put in the DOM tree, data for it is being fetched, but it is not rendered
WVideo with 1 source => works
WVideo with 2 sources with the same mime type => works
iOS 5+ => unknown
No data to display
