Hi,
First of all, thank you for your help regarding yesterday's session, After switching to a different de-serialiser I have a reading from i2c of the camera.
The next step I am trying to achieve is streaming the video to HDMI and save to SD card, but I am having trouble with Media control command.
and gst.
edit Update - I have managed to receive a video stream using the following gst line:
gst-launch-1.0 v4l2src device="/dev/video2" ! video/x-raw, width=1280, height=720, framerate=30/1 ! kmssink driver-name=tidss
but as you can tell this is not the full resolution and quality
the following message after running ./init_script.sh (notice the error)
root@tda4vm-sk:/opt/edge_ai_apps# ./init_script.sh
Unable to setup formats: Invalid argument (22)
CSI Camera 0 detected
device = /dev/video2
name = ar0234 8-0044
format =
subdev_id = 2
isp_required =
I am trying to run:
media-ctl -d /dev/media0 --set-v4l2 '"ar0234 8-0044":0[fmt:UYVY2X8/1280x720]'
and I get:
VY2X8/1280x720]'opt/edge_ai_apps# media-ctl -d /dev/media0 --set-v4l2 '"ar0234 8-0044":0[fmt:UYV [ 7732.377916] Skipping Previous mode set ...
I have double checked, the media port is 0, i2c address is right.
Also if I try to run gst command:
gst-launch-1.0 v4l2src num-buffers=-1 device=/dev/video2io- mode=5 ! “video/x-raw,width=1280,height=720,format=UYVY”!fpsdisplaysink video-sink=autovideosink text-overlay=falsesync=false -v
I receive:
sink text-overlay=falsesync=false -vght=720,format=UYVY�”!fpsdisplaysink video-sink=autovideosmo
-sh: !fpsdisplaysink: event not found
please check the following logs for debug:
