DM365 jpegenc sample code: hanging in process call

Chris Meng

Hi,

My customer complained that the DM365 Jpegenc made the image blur (reduce the shapness) compared with original YUV or the jpeg file encoded by PC. So I want to try the file to file jpegenc sample code to check this issue.

I used the FC 2.4 and the other tools in ipnc 2.6 (kernel 2.6.18) and can build the jpgenc-r well. But when I run the app, it hangs in process call. I added the print info before and after the process call and I only see the print before process call is printed out.

With same environment, the h264dec sample code can work ok.

Would you pls kindly advise what I missed?

Below is the log info.

Chris,

Are you using a DM365 EVM for your tests? What is the customer platform? Is the customer using an SDK from TI? Which one?

thanks

Hi Chris,

You can try executing only " ./jpgenc-r".

If you want to try sample jpeg_E, I would suggest you to try with standalone code Or dvsdk_3_10_00_19.

Cesar，

I am testing the jpgenc on DM36x IPNC HW. Same HW can work ok with DM36x h264dec cdoec sample code.

Customer didn't know which version of jpgenc they are using due to the engineers leaving. They are not using TI' sdk, but 3rd party's OS.

Prashanth,

Yes. I have tried " ./jpgenc-r" and changed to use basic param config, but met same problem. I am trying to encode a YUV file from customer to jpeg file to see if I can reproduce customer's blur problem. Any other suggestion?

Hi,

What is the quality factor of JPEG? JPEG Encoder can accept quality factor from 1 to 100. You can increase the quality factor and encode. Please attach input and encoded snaps for better understanding.

Hi Chris,
Is the issue still open?

Prashanth,

No. I still can't run DM36x jpegenc sample code well.

Chris,
On DM36x EVM - standlaone set up with below components its working fine at my side. I don't see hang.
− Framework Component (FC) version 2.23
− XDC version 3.15.01.59
− LSP version 2.10

You can try this sample code
