I am using this pipeline with gstreamer 1.4.5 and current media branch but I am
getting very poor performance 1-2 fps when playing 800x400 video. Is it possible
that fbdevsink is too slow for that? Does anyone know what is going wrong?
In this context, you most likely have a conversion happening in
videoconvert followed by a copy at fbdevsink. Framebuffer device is not
a very good solution if performance matter (no possible zero-copy).
Specially if the selected framebuffer color format does not match the
decoded format.
