I've tried both the libass ad assrender plugins. Seems like assrender is more
cpu-intensive than libass - e.g. I am unable to play HD videos with assrender,
while they play fine with either mplayer or libass. The pipeline I use for
assrender is 
filesrc location=<filename> ! matroskademux name=v v.subtitle_00 ! queue ! sub.
v.video_00 ! queue ! decodebin ! ffmpegcolorspace ! assrender name=sub !
ffmpegcolorspace ! videoscale ! xvimagesink v.audio_00 ! queue ! decodebin !
pulsesink

On the other hand assrender is able to use fonts attached to the stream which
is a big advantage for me.

Is there a way to persuade e.g. totem to use the assrender plugin? It's
suboptimal to have to use gst-launcher...
