I am trying to configure gstreamer to capture video and display it to the LCD on a DM3730. I have the camera capture working, but the problem appears to be DRM related. I am able to stream video to fbdevsink, but it doesn't appear to route to kmssink. When I run modetest, it shows the following: Connectors: id encoder status name size (mm) modes encoders 45 44 connected DPI-1 105x67 1 44 modes: name refresh (Hz) hdisp hss hse htot vdisp vss vse vtot) 480x272 60 480 483 525 527 272 274 285 288 9000 flags: phsync, pvsync; type: preferred, driver props: 1 EDID: flags: immutable blob blobs: value: 2 DPMS: flags: enum enums: On=0 Standby=1 Suspend=2 Off=3 value: 0 5 link-status: flags: enum enums: Good=0 Bad=1 value: 0 6 non-desktop: flags: immutable range values: 0 1 value: 0 4 TILE: flags: immutable blob blobs: value: 20 CRTC_ID: flags: object value: 46 There is more but I think that's the connector-id that I am supposed to use. I have been trying to force the connector ID with g-streamer: GST_DEBUG=2 gst-launch-1.0 -v v4l2src device=/dev/video6 ! videoconvert ! kmssink force-modesetting=true connector-id=45 Unfortunately, I get an error that shows # GST_DEBUG=2 gst-launch-1.0 -v v4l2src device=/dev/video6 ! videoconvert ! kmss ink force-modesetting=true connector-id=45 Setting pipeline to PAUSED ... 0:00:05.130981445 251 0x115f20 WARN kmssink gstkmssink.c:835:gst_kms_sink_start:<kmssink0> error: Could not open DRM module (NULL) 0:00:05.131469726 251 0x115f20 WARN kmssink gstkmssink.c:835:gst_kms_sink_start:<kmssink0> error: reason: No such file or directory (2) 0:00:05.132263183 251 0x115f20 WARN basesink gstbasesink.c:5367:gst_base_sink_change_state:<kmssink0> error: Failed to start ERROR: Pipeline doesn't want to pause.

I get the following message while booting, but I don't know if it's related: [ 7.279083] omapdrm omapdrm.0: DMM not available, disable DMM support Does anyone have any suggestions? adam
