J784S4XEVM: unable to dump debug images in multicam application

Hi Darshan,

You may have to make (mkdir) the output folder manually first.

I recall there is some issue in multi-cam app for dumping images after some previous tiovx update.
Only some combinations may be supported.
So, you may have to try turning on each of the flags individually (not together).

# enable writing final output 0-disable, 1-enable

en_out_img_write 1

I don't think this is needed.
You may keep it as 0.

DARSHAN S said:

# enable writing csix output 0-disable, 1-enable

en_out_capture_write 1

This is for sensor raw image.

DARSHAN S said:

# enable writing viss output 0-disable, 1-enable

en_out_viss_write 1

This is for VISS output yuv image.

Hi Gang Hua,

I created the directory using mkdir .

Now I am able to dump raw image from multiple channels when i enable en_out_img_write 1 alone , but when i enable en_out_viss_write 1 alone the fps becomes zero and the application crashes when press "s" to save frames. 

Can you please help me fix this?

Thanks,

Darshan S

Yes, that should work.

That seems what I recall as well for mutli-cam app.

I typically use the single-cam app the capture/dump raw and yuv images.

I am not familiar with tiovx s/w details unfortunately.
We have filed a bug previously and have to wait for it to be prioritized.

While doing that, could you disable raw image dumping?

That seems working for me, but it only captures VISS output for the first camera on my j722s evm with SDK 11.

Hi Gang Hua ,

Yes i am disabling the raw image dump and only enabling viss dump , the fps becomes zero and application crashes.

I am using 10.1 sdk.

Thanks,

Darshan S

Ok, thanks for the confirmation.
There might be some tiovx update between 10.1 and 11.1.

BTW, j722s SDK 11.0 has the same behavior as 11.1.
