Hello,
I'm using the MPEG4_HDVICP encoder (v2.00.00) from the DVSDK 3.10 on a DM368. The implementation was strait forward and finally I succeeded creating a MPG4 stream.
But now I observe two problems were I need help. Maybe this problems are related to each other.
First of all I get an annoying CMEM error each time I encode an image i.e. when calling VIDENC1_Process().
...
CMEM Error: getPhys: Failed to get physical address of 0

All prior calls like VIDENC1_create(...) or VIDENC1_control(..) succeed without any error or warning. I checked the buffers that I pass to the codec but there is no NULL pointer. The generated MPEG streams looks OK.
My other problem is the low performance of the codec. Currently it takes 58ms to encode an image of 1280x960 so I can achieve 17fps only . But maybe this is related to the CMEM error.
Here are my parameters:
