Dear Experts,
I have a MIstral DM8148 and I want to utilize the existing demo Decode->Display (demo_vdec_vdis.c) to use the encoder also, for this purpose I want to disconnect one of the DUP element connections which goes to display and send it to the encoder and then write the encoded stream to the file.
But seems that I misunderstanding the concept of buffers and data flow between components, I will appreciate any help, to be more specific can any body draw me a flow from DUP to Encoder to Save Stream, which include buffer and link types.
Thanks in advance.
Ilia.
Below is code part example of what I tried to do, but it not working.
