DM365 Display Initialization

Woody Douglass

Hello! I am trying to develop a streaming video device based on a DM365 kit from Z3 technologies. I have made my streamer, a derivative of the DM365 'encode' demo that ships with the dvsdk. After stripping out the UI and adding a display thread (similar to the one in the 'encodedecode' demo but without the pause functionality) I am seeing an interesting behavior.

My application works just fine when run after the encodedecode demo, but if i run it from a cold boot, nothing shows up on the display. The streaming and UI stuff i added works just fine, however.

To me, this looks like an initialization issue. Are the steps to initialize the display within DMAI documented anywhere? how can i debug the initialization state of the system?

Thanks a lot,

Woody

Hello,

Please note that DMAI display module does not configure attribute window (/dev/fb2). Are you configuring attribute window (i.e transparency) from your application ? Please look at the dvsdk demo - it does set the attribute window so that you can see the video plane.

Thanks

Thanks a lot...that was the answer. I missed it because ui.c was in the parent directory to the demo.

Thanks again.
