Directly drive 3d TV in FullHD?
Posted: Thu Apr 08, 2021 8:18 am
Hi all,
has anyone tried to output the dual-camera video to a 3D TV directly?
I know it can be done using raspivid's preview mode eg in SBS mode when the TV supports that. But would that be possible in FullHD (1920x1080) as well?
The Raspi3 framebuffer is limited to 1920x1080, so it cannot hold 2 FullHD images in SBS or TB mode. But in theory, it is capable of generating an HDMI 1.4 compatible 3D frame-packing output in FullHD. At least omxplayer supports doing this, see https://www.raspberrypi.org/forums/view ... p?t=131954
But I guess raspivid cannot do that. Or can it?
BTW: I was looking for the source code for StereoPi's modified raspivid, but could not find it. Can someone point me in the right direction?
Best regards
Andreas
