IGEP SMARC i.MX6

IGEP SMARC i.MX6 has support for IGEP CAM OV5640, download firmware or compile latest Yocto Project 1.8 - Poky 13.0.y "Fido".

The following steps and results has been tested with IGEP SMARC Expansion (BASE0040).

Resolutions and frame rates for IGEP SMARC i.MX6

The following table shows the available resolutions:

Resolution: Capture mode: Available frame rates per second: Max captured frame rates per second:
QCIF (176x144) 7 15/30 30
QVGA (320x240) 1 15/30 30
VGA (640x480) 0 15/30 27,41
NTSC (720x480) 2 15/30 30
PAL (720x576) 3 15/30 30

720p (1280x720) 4 15/30 28,44
1080p (1920x1080) 5 15 14
QSXGA (2592x1944) 6 15 6,5

Gstreamer pipes for IGEP SMARC i.MX6

IMPORTANT NOTES:

See available fps-n parameters into Available frame rates per second column from table Resolutions and frame rates for IGEP SMARC i.MX6.

See available capture-mode parameters into Capture mode column from table Resolutions and frame rates for IGEP SMARC i.MX6.

  • Stream video to main display output in mode 3 (PAL): 
export DISPLAY=:0.0; gst-launch imxv4l2src fps-n=30 capture-mode=3 device=/dev/video0 ! imxv4l2sink
  • Stream video to main display output in mode 4 (720p):
