I’m using i.MX8M Mini with “BSP 7 Downstream Linux Reference Multimedia” (7.1.0+build.3) image.
When I ran the following GStreamer pipeline with VPU encoder element(vpuenc_h264):
And then, I got the following logs including errors.

Also, I ran the same pipeline with the BSP6 image (BSP 6 Downstream Linux Reference Multimedia 6.8.1+build.15), it worked fine.
Could someone please tell me how to use the VPU encoder with a BSP7 image?

Hello!
I’m sorry to hear you’re experiencing issues with the VPU encoder on your Verdin iMX8M Mini using BSP 7. Let’s explore some steps that might help resolve this:
Review BSP Changes:
Check the release notes for BSP 7 to see if there are any changes related to the VPU or GStreamer that could impact the encoder’s functionality.
Verify VPU Driver and Firmware:
Ensure that the VPU driver and firmware are correctly installed and compatible with BSP 7. Sometimes, updates in the BSP require corresponding updates in the VPU firmware.
Check GStreamer Plugin Compatibility:
Make sure the GStreamer plugins you are using are compatible with BSP 7. There might be updates or changes in the plugin versions that could affect functionality.
Examine Pipeline Configuration:
Double-check your GStreamer pipeline configuration for any syntax errors or deprecated elements that might not be supported in the new BSP version.
Experiment with Different Parameters:
Try adjusting the pipeline parameters, such as resolution or framerate, to see if the issue persists. This can help identify if the problem is related to specific settings.
Investigate Known Issues:
Look into any known issues or errata for BSP 7 that might relate to the VPU or GStreamer. This information can sometimes provide insights into unresolved bugs or workarounds.
I hope these steps help you get the VPU encoder working with BSP 7. If the issue persists, examining the specific error messages and logs in more detail might provide further clues.
Best regards,

Dear Kyohei @k_ichi , thanks for the additional information. I don’t see any open ticket on this regard so let us check more in detail. The information you have provided is very useful.
I hope I can report back to you in 1-2 weeks.
Sorry for the inconvinience but thank you for your patience.
Thanks for the info @Urs . Our internal team is checking on it. However I checked before in a Toradex Multimedia reference image with a Verdin iMX8M Plus:
Dear @k_ichi@Urs , we believe this is an issue introduced in a recent patch from NXP Downstream and that it can be reproduced in IMX8MM-LPDDR4-EVK: IMX8MM-LPDDR4-EVK Help Request
We will try to reach out to NXP to see if they can patch in the shorter term.
Dear @Urs , @k_ichi , I received confirmation that the issue was patched within NXP / Toradex BSP and that it should be fixed in the latest 7.3.0 Nighly version of the BSP.
Feel free to check within our CI/CD feeds or just wait until we release the next Monthly version.
We will publish more details in our Issue Tracker. The reference will be ELB-6418.
Sorry for the inconvenience but thank you for your patience in this matter.
