Hello,
I am having an issue much the same as in the related thread.
When attempting to run any gstreamer pipelines on the AM57X in linux, I get the following:
gst-launch-1.0 filesrc location=/test.yuv ! videoparse width=352 height=288 format=nv12 ! queue ! ducatih264enc ! h264parse ! queue ! ducatih264dec
Setting pipeline to PAUSED ...

The related thread indicated that in his/her case, that /dev/rpmsg-dce was not created. In my case, however, that device does exist. I checked the resource table/config file and compared the memory map to what is in my device tree, and that matched:
ipu2_cma_pool: ipu2_cma@9B800000 {
compatible = "shared-dma-pool";
reg = <0x0 0x9B800000 0x0 0x3800000>;
// size = <0x0 0x3800000>;
reusable;
status = "okay";
};

PM_DATA: { name: "PM_DATA", base: 0x95070000, len: 0x00020000, space: "data", access: "RWX" }
Are there any other ideas of what to look at here?
