dm368 1080p performance issue

From the log it looks like you are running in DDR_IN mode.

PLease run it in AVSERVER_CAPTURE_RAW_IN_MODE_ISIF_IN mode to get maximu performance, you cna use resizer 1 for 10810p and other for D1.

In DDR IN mode, due to extra DDR copy the performance drop will be seen

Also, Can you check you codec params to get the best performance for 1080p+D1 config?

Raghu

few checks for create params

encodingPreset = XDM_HIGH_SPEED

Hi Raghu,

Thank you for the reply.

We are using a camera module which outputs 1080p data in 16-bit YUV 4222 format. When we use the AVSERVER_CAPTURE_RAW_IN_MODE_ISIF_IN mode we do not get proper video. It is a green screen with noise.

My question is , can we run in "AVSERVER_CAPTURE_RAW_IN_MODE_ISIF_IN"  mode to capture 16-bit YUV 422 format?

Also according to the document "Suggested settings for (1080P + D1) - 30fps on DM368E" from TI , it says performance can be achieved by running on the fly resize to D1.

Can you direct us as to what part of the IPNC ref desing code to modify to run in this mode?

Thanks in advance.

Hi

I am having same issue can any body tell me what is difference between "AVSERVER_CAPTURE_RAW_IN_MODE_ISIF_IN" and "DDR_IN" mode ?

And in which file I need to look for, to change captureRawInMode ?

Thanks,

Jignesh

Hi Padmini Vijayakumar 

I am curious to know whether you were able to achieve the desired 30 fps and 

also whether you got the AVSERVER_CAPTURE_RAW_IN_MODE_ISIF_IN capture mode working.

Thanks 

Ashok

Hi Ashok,

We were able to achieve 30 fps and we were also able to get AVSERVER_CAPTURE_RAW_IN_MODE_ISIF_IN working.

how to set the other clock without arm、ddr and HDVICP？
