Thank you for the link!

Will the platform based on OpenRISC be suitable for a Linux system
with DirectFB and a video framework e.g. GStreamer?

Thanks for the suggestion. I will ping the community there.

I will be eagerly waiting for the videos once the actual event is
finished on the 21st of April.

Thank you once again for your help.

Warm regards,
