Hi Edward,
Thanks for the inputs!
Since I am facing the same problem on scratchbox (As I explained in my first
mail), I tried GST_DEBUG ... on scratchbox environment (No debug enabled in
:-( my 770).
I am not getting any clue from the logs. I have attached the generated logs.
Can you please help me?
Thanks and regards,
Sharath

Hi,
First REMOVE your registry (~/.gstreamer-0.10/registry*), then run the
following :
# GST_DEBUG=2 gst-inspect-0.10 > log 2>&1
You can then look through the 'log' file to see the reason why your
plugin isn't being loaded. If you don't see anything regarding your
plugin, that means that it is located in the wrong path.
BTW, I think debugging was disabled on the N770 gstreamer by
default... so I hope you have a debug-enabled version of gstreamer else
you will not be able to go very far.
