Verdin iMX8MP Gstreamer issue with encoder and decoder

Technical Support

I am trying to run a gstreamer pipeline on the Verdin iMX8MP mounted on the Dahlia Carrier Board. However, when running the pipeline, I am coming up against the error “vpuenc_h264-0: Could not initialize supporting library”.

I built a custom Yocto image using the tdx-reference-multimedia-image and a few minor customizations.

The pipeline I am trying to run:

gst-launch-1.0 videotestsrc ! video/x-raw, format=I420, width=640, height=480 ! vpuenc_h264 ! filesink location=videotestsrc.mp4

I also tried other pipelines, including one suggested in another topic and was getting the same message for vpudec.

Hi @dandresky,

I’ve never seen this issue before on my side (cc: @henrique.tx), but found some links that might be useful (one from NXP):

Can you please check if this is not related to your custom image? Could you please try one of our images?

Best Regards,
Hiago.

Hi @dandresky !

There was indeed some problem with Gstreamer and Verdin iMX8M Plus recently: Toradex System/Computer on Modules - Linux BSP Release, ELB-4699

I just installed the latest image available:

And I could run your pipeline without issue. Could you please also test on your side?

On a side note, please see that the support for Verdin iMX8M Plus is still not complete on BSP 6:

Best regards,

Thanks @henrique.tx

I just tried the prebuilt images for both the 6.0 BSP (kirkstone) and 5.7 BSP (dunfell). I see the issue with 6.0 but 5.7 works as it should. Is there an issue I can follow that tracks progress for BSP 6.0 support on the Verdin board?

Hi @dandresky,

We have the issue tracker here: Toradex System/Computer on Modules - Linux BSP Release.
And also the roadmap that gets updated once we enable more features (in the link that @henrique.tx shared with you).

Best Regards,
Hiago.
