Hi,NVIDIA
We want to translate the NvmediaImage to EGLImage because we could only get NvMediaImage from the producer and our algorithm could only process with EGLImage.
I have refer to “EGLStream” in drive-linux/samples/nvmedia, but it couldn’t work well.

Hi,Nvidia

Hi,bro
My business mail is gaojy0408@thundersoft.com but I couldn’t log in with this count.
I also report a case on NVOnline but it seems has no progress so I submit a topic on forum.

Is there any suggestion about this question?

Dear @932315769,
Could you confirm if you are using DRIVE AGX Xavier/ DRIVE AGX Orin platform?

Dear @932315769,
Please confirm the DRIVE release on target. May I know why you are looking for EGLImage only? Did you check nvm_eglstream sample if it can be used in your use case to share data across APIs.

Hi,bro
My platform is DRIVE AGX Orin and the os version is 6.0.1.
My requirement is get the NvMediaImage from producer(done) and translate the buffer to EGLImage(todo) then post the buffer to render(done).

Dear @932315769,
just to clarify, DRIVE OS does not have NvMediaImage → EGLImage conversion APIs.

Hi,bro
Yes I knew,but I found some function to complete this action.
I use the eglStreamImageConsumerConnectNV and NvMediaEglStreamProducerCreate,NvMediaEglStreamProducerPostImage to post the NvMediaImage to the producer and then use eglQueryStreamConsumerEventNV to acquire the EGLStream and EGLImage from the consumer.
Could this method work?

Please see if the usage in wetson wayland compositor implementation can help with your use case.
