[gst-devel] Initialization Time Reducing!

[ensonic]

hi,

when gstreamer is started the first time or new plugins have been installed
it creates a registry cache (e.g. ~/.gstreamer-0.10/registry.*). If it
can't write the cache the registry will be rescanned each time. Is that
happening in your case.

Next, as Edward already suggested, the binary registry will help. Build
core from cvs using --enable-binary-registry. Additionally you can search
the list archives. I previously wrote a mail about which components can be
disbled to slim down the lib sizes.

Finally, remove all plugins you don't need.
