Not working with GPIO based screens #6

Closed ambanmba closed 5 years ago

ambanmba commented 5 years ago

Describe the bug The window that opens with the video stream will not open on a screen that is attached via the GPIO pins. These screens use a driver such as this one to output the video via GPIO instead of HDMI. https://github.com/goodtft/LCD-show

To Reproduce Steps to reproduce the behavior:

  1. Install per README.md
  2. Configure my feeds in layout.conf.default
  3. Run 'sudo displaycameras start'
  4. Image is not displayed on the main screen connected via GPIO and from which the command was run, instead it appears only on the HDMI screen with no way to "move" the window back to the GPIO screen.

Expected behavior Expected the sudo displaycameras start command to display output on the screen connected to the GPIO.

GPIO screens, being rather small are not really the targeted use case. Expectation is an HDMI display.

Try to prepend your feeds with "--display=4 "

Anonymousdog commented 5 years ago

If that throws errors during testing, replace /usr/bin/displaycameras with this version, https://raw.githubusercontent.com/Anonymousdog/displaycameras/layers/displaycameras

Thanks for that... I replaced /usr/bin/displaycameras with the version you suggested (otherwise it was throwing errors).

--display=4 stopped showing the display on the HDMI, but was not showing on the GPIO screen. I tried --display=n where n=1-5 and in all cases except n=4 the image was showing on the HDMI. With n=4 the display wasn't showing anywhere.

No idea. Unless there's some command line parameter we can pass to omxplayer to get it to display video on that screen, you're out of luck.

ambanmba commented 5 years ago

I'll do a bit of research on this one and get back.

Dependency constraint: omxplayer's --display parameter doesn't support CPIO displays.
