--- Comment #12 from Víctor Manuel Jáquez Leal <vjaquez at igalia.com> ---
I had some time to test this. A couple comments

1. With the patches from bug 796169 and the proposed patch here, the artifacts
are lesser than before (the stream was impossible to see)

2. Perhaps I doing something wrong, but I don't perceive the jittery as stated
in comment 11

3. Neither the "use after free" in valgrind (again, I might not doing it
correctly)

4. Oddly playing this stream, with the patch, nothing is rendered using
glimagesink, meanwhile using vaapisink or xvimagesink it is OK.

The problem with the stream is that, in certain point it announces two views,
but they are not available, only one. Thus, imho, the patch looks correct but
we need to ignore max_views changes when there aren't those views available, if
this is possible.
