Are there any issues with playing graphene videos on other devices? We see sluggish/playback issues when playing videos on other devices. Maybe our video settings are wrong?
video recordings
What does "graphene videos" mean? Videos recorded in the grapheneos camera application? Screen recordings? Some other 3rd party software you are running on grapheneos?
If you're talking about "sluggish" playback, that sounds to me like it could be that the other device you're using simply doesn't have the capacity, this would happen, for instance, if you record a 4k video and encode it with HEVC and try to play it back on a device that lacks an HEVC decoder, or a decoder capable of handling the high resolution.
First thing to try is lowering the resolution to no more than 1080p. Second, I'm not sure if the GraphenOS camera application can make videos using h.264, but maybe try to find a camera application that can.
