Hi NV,

When running ./sample_camera_gmsl --write-file=/home/nvidia/Desktop/test.h264, I got the error message as follows:

NvMediaEglStreamWrapperInitializeEgl: Cannot find function NvMedianvmEglStProducerCreateCommon:Wrapper Initialization failed
NvMediaEglStreamProducerCreate: Failed to Create Producer
[04-07-2017 16:03:35] StreamProducerNvMediaImage: could not create stream producer!
[04-07-2017 16:03:35] DriveWorks exception thrown: DW_CANNOT not create NvMedia Image stream producer.

Can you help to fix this error?

Thanks!

Dear songwen.huang,

Could you please me know the following?
-. What version of DriveWorks/PDK are you using?
-. What kind of camera are you using?
-. What happens if you just run the ./sample_camera_gmsl command?

I can run the command without any issue with DriveWorks 2.0.

Dear SteveNV,

-. What version of DriveWorks/PDK are you using? DriveWorks 2.0
-. What kind of camera are you using? AR0231 RCCB Rev7.
-. What happens if you just run the ./sample_camera_gmsl command? Will try this and keep you posted.

Dear songwen.huang,
Any update on the issue?

Dear SteveNV,

After executing ./sample_camera_gmsl, I got the same error:

NvMediaEglStreamWrapperInitializeEgl: Cannot find function NvMedianvmEglStProducerCreateCommon:Wrapper Initialization failed
NvMediaEglStreamProducerCreate: Failed to Create Producer
[04-07-2017 16:03:35] StreamProducerNvMediaImage: could not create stream producer!
[04-07-2017 16:03:35] DriveWorks exception thrown: DW_CANNOT not create NvMedia Image stream producer.

Do I need to modify any setting in Xavier to fix this?

Dear songwen.huang,

Could you please re-boot(cold re-boot) the system and re-try to run it? Thanks.

Hi songwen.huang,

Have you managed to get the sample running?
Any result can be shared?

Hi kayccc,

The issue was fixed after typing the command:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib:/usr/lib/aarch64-linux-gnu
