Black flashes during video playback on another sd card

Hi!

I am using a raspberry pi 3 for OSMC. I wanted to try out a multiboot set-up and bought another sd card. So I installed a vanilla version of OSMC along side retropi. I am using the same version (latest) for both installations. Everything works fine except to weird things:

  • Black flashes during playback after a few seconds in the movie / show. The screen goes black for a very short time. Audio continues. The flashes are random and continue forever until I stop the video. It seems like the tv loses its connection for a fraction of a second.
  • The resolution when OSMC is booting is only 640x480. I have to set 1080p manually in the system settings. My other installation but directly in 1080p.

This does not happen with my first OSMC installation on the same pi with the same movie files. If I change back the card, everything works fine on the same hardware. It has to be some kind of configuration.

The last part might have anything to do with it. I mirrored all settings regarding playback (sync refresh rate to display, etc) Any idea? I will upload logs soon! But my assumption is that the logs will not show anything.

To get a better understanding of the problem you are experiencing we need more information, including logs from you. Please see How to submit a useful support request - General - OSMC for advice on how to help us.

Sorry. I editied the first post and will provide you with logs asap.

I figured it out. I used noobs for the installation of the second sd card. Noobs generated this /boot/config.txt:

gpu_mem_1024=256 hdmi_ignore_cec_init=1 disable_overscan=1 start_x=1 disable_splash=1 dtoverlay=lirc-rpi hdmi_force_hotplug=1 hdmi_edid_file=1 config_hdmi_boost=4 overscan_left=24 overscan_right=24 overscan_top=16 overscan_bottom=16 disable_overscan=0 gpu_mem_256=112 sdtv_aspect=1 dtparam=gpio_in_pin=18 gpu_mem_512=144 dtparam=gpio_out_pin=17

After I put this in the config.txt and everything is fine again:

gpu_mem_1024=256 hdmi_ignore_cec_init=1 disable_overscan=1 start_x=1 disable_splash=1 dtoverlay=lirc-rpi gpu_mem_256=112 sdtv_aspect=1 dtparam=gpio_in_pin=18 gpu_mem_512=144 dtparam=gpio_out_pin=17
