Hi ,
I want to run gstreamer as a embedded multimedia framework. But I feel its no so good for embedded platforms as it memory footprint is big as well as it consumes lot of cpu. Hence ,I am trying to optimize the core , but unable to find the starting point.
; Can someone help, as to how can gstreamer be used effectively on embedded platforms? or may be give few pointers as to how can one go around , for optimizations.
Thanks
cheers

Hi,
for sure you won't be able to run on an embedded platform each and
every GStreamer plugin. But, by simply cutting out plugins you don't
need, you can end up with a suitable embedded-friendly Gstreamer
framework. Nokia 770 and N800 devices are running Gstreamer without a
problem.
In our experience Gstreamer is not CPU hungry, on the contrary. For
example, you could not notice any CPU load difference comparing a
mad-based mp3 application decoder using gstreamer and madplay.

The N700 and N800 are not small devices. 128Mb/256Mb of
flash
respectively is much larger than most consumer electronics
devices
which are more likely to ship with 4-8Mb of flash total
(that's
megabytes btw).

Yes, but at that point you requirements from GStreamer are
also quite
small so maybe all you need is 2-3 audio decoding plugins
for instance.

Hi,
you can slim down the core a bit by disabling features. Try
enabling
the binary registry, disabling loadsave,index,trace. You can
also
optimize on the glib level by doing adding these to you
cflags for a
release build:
G_DISABLE_ASSERT, G_DISABLE_CHECKS,
G_DISABLE_CAST_CHECKS
Then of course only ship the plugins you need.

unless it needs to resample .... in which case it might burn
30% of the
total CPU on a moderately modern opteron. sometimes,
licenses hurt in
deep ways ...
