Chris,

It appears as capture source is not detected. Is the set-up working for capture-encode demo ?

Second point For DEI both ports must be connected to some component. If only one port is used, other should be terminated such that buffers received in that port are recycled back. else DEI component would not work.

Vimal,

         Thanks for your reply.

         Yes,the capture-encode demo  is work, you can see the demo is under the same dir "/usr/test/".

         For the second point,  I try to put the dei component second output port buffer to recycle to capture component, but the code I change is still not work.

         Can you give some detail avdvice on how to change this?

         Best Regards

chris
