playbin2 and mpeg2 elementary stream: perfomance issue

[Christophe Oosterlynck]

I forgot to mention that I've tried the HEAD of the 0.10 branch already as
I saw some performance fixes there. However, it doesn't make any
difference. Would 0.11 make a big difference?

The fact that inserting a queue between the filesrc and the mpegvideoparse
element solves my problem, is not relevant? I shouldn't be focussing on
that but rather on performance issues in mpegvideoparse? It probably won't
be any other element as I have the same result when using fluvadec +
fluvasink instead of mpeg2dec + xvimagesink.
