Thank you for your help @tpm and @Honey_Patouceul . I managed to resolve the issue by removing VideoWriter from OpenCV and using GStreamer instead. I’m really enjoying working with GStreamer! I still feel like I’m looking at the iceberg from outside, thus I appreciate your guidance more than ever.
There are few more issues to address, so I’ve created a new post to keep things organized. Could you please take a look at my latest post here?
I’m looking forward to your suggestions. Thanks again!
