fwrite on Video M3

Jayakrishnan

I am integrating a custom encoder on IPNC RDK. The encoder is able to process frames in real time, but the decoded frames turn out be just black frames. So I am debugging the issue. I want to ensure that the encoder gets proper frames at the input. For this I would like to use fwrite() to dump the frames on M3 Video side. While this is compiling, it fails to dump frames. Is there any other method to dump frames on M3 Video? Why fwrite() is not working? I have no problems dumping frames on A8 side. Pls answer.

Hi,

You can do file operations only on A8 and neither on M3 nor DSP.

So you can modify the use case to route the frames to A8 then save them to file.

If it is only for debug purpose then save the frame from memory location to a fine in CCS.

Hi Anand,

Yes, for debugging purpose only.

My H.264 encoded stream has some problem. After decoding using Codec Visa , the first frame (IDR) has lot of noise in it. But the second frame ( a P frame) is relatively better. What could be the issue?
