Hi,
When I run encode demo on dm6467, I find a strange problem. There is a sudden drop of framerate in the process of encoding.
The output information is as follow:
# ./encode -v 1.264 -a 1.aac
Encode demo started

This is quite strange as the dspload goes down at the same time.
Who can explain this?
I want to get a stable framerate of encoding. Can anyone help me?
