I am using Jacinto 6 ES 1.0 (DRA7xx) in order to stream Android Auto video from USB connection, for the purpose I simply read the payload and write it to a video buffer, this runs smoothly on many platforms including Raspberry Pi. However, when run on Jacinto 6 ES 1.0, with SDK 5.0.0.01, I am having diffculties with its poor performance as the video is a lot of the time frozen. I think this is because of the fact that ducati gstreamer plugins somehow do not work in my case. To my understanding gstreamer's playbin is optimized in such embedded boards so I only have to make sure gst pipes and plugins are working correctly.
Here is the log:
GST_DEBUG=3 /usr/bin/app -platform eglfs
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).

I should also add that I have customized tisdk-rootfs-image.bb to have the following. But I think it's only enough to have the "packagegroup-arago-tisdk-multimedia" package for ducati plugins.IMAGE_INSTALL += "\
packagegroup-arago-base \
packagegroup-arago-console \
packagegroup-arago-base-tisdk \
packagegroup-arago-test \
packagegroup-arago-test-addons \

"
I would appreciate if anybody could give me ideas how to fix this problem. May it be patching or appending to yocto packageconfigs for ducati-gst.
Thank you in advance.
