Hello,
Something funny is happening...
We're using using IPNC RDK 3.8 on DM8127.
We built an application using a custom resolution for a fish-eye lens (1200x1200).
I noticed short (48 pixel wide) black stripes whenever there is motion in the frame. I copied a RAW frame by using the following console code:
/opt/ipnc/bin# ./mem_rdwr.out --fsave B0800000 2247168 /opt/ipnc/dsp.yuv
0xB0800000 - the address of the buffer that saves RAW, unchanged frames in the DSP in order to perform our Video Analytics algorithm.
2247168 - the 1232x1216x1.5 - size of 1200x1200 frame when using the noise filter
Attached is what is received after viewing using YUVplayer.exe
As you can see there are lines on the left side of the screen. These lines disappear when the scene is static. Only when there's motion do they appear.
What module is responsible for these lines? It must be some function in the Ducati - one of the M3 cortexes.
My hunch that it may have something to do with motion detection - maybe for DMVA applications?
Any ideas would be appreciated.
Thanks,
Mechi
