Hey, I am looking for an example of how to stream video data in RAM to HDMI output on ZCU104 board (with FB Read, HDMI TX, and Video PHY). It looks like there is a video_cmd application that is supposed to do this, but it seems like it is only being distributed in binary. I was wondering if there was source code for video_cmd that I could look at or if there is another example of how to use Linux software to coordinate the DMA transaction to get the video data into the PL to the HDMI output.

Will this solution work running on APU on ZCU104? I know that there is a Silicon Labs chip at the end of the pipeline that I wasn't sure was on the ZCU102 or if this software needs to account for it.
Also a major source of confusion for me is why the app is not built into the PetaLinux distribution. Why is it compiled separately. I am used to building apps that show up in /usr/bin or a directory like that in the filesystem the PetaLinux tools generates.
