raspivid -3d sbs seems to only overlay one of the two camera captures when the preview is turned on. How can I enable a full side by side preview or is this just not possible?
If you want to just view the two images side by side, then you'll need to reconfigure the mmal_connection from camera to video_render to MMAL_ENCODING_I420 instead of MMAL_ENCODING_OPAQUE. Opaque inherently includes the two channels as independent images.You will need to instruct TVService to switch your TV into a stereoscopic mode before running your camera command if you want to view the stereoscopic output. For me that is something liketvservice -m CEA will give you a list of the modes your TV supports.
Code: Select all
tvservice --explicit="CEA_3D_TB 4" tvservice --explicit="CEA_3D_SBS 16"
