Gstreamer stuck on FSL Community BSP version

yaolinchang · ‎11-23-2015

Hi All,

We download FSL Community BSP source code as below:

repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b fido

and execute gstreamer for camera capture.

Our command as below:

gst-launch-1.0 imxv4l2src device=/dev/video1 ! 'video/x-raw, format=(string)NV12, width=1920, height=1080, framerate=(fraction)60/1' ! imxvideoconvert_g2d rotation=3 ! video/x-raw,format=RGB16,width=1080,height=1920 ! autovideosink &

However, gstreamer will be stuck.

The log as below:

root@imx6qsabresd:~# WARNING: erroneous pipeline: could not link imxv4l2videosrc0 to imxvideoconvert_g2d0

hy,

maybe you have chosen the false "capture-mode". i thoght that it is not possible to capture in "full HD" from ov5640. is you pipeline running without that filter stuff: 'video/x-raw, format=(string)NV12, width=1920, height=1080, framerate=(fraction)60/1' ??

cheers

Hello,

The message "ERROR: v4l2 capture: slave not found!" - may mean, that

camera hardware is not supported in the selected software configuration.

Please check, using the gst-inspect command what cams and features are supported

in Your configuration. Perhaps "device=/dev/video1" is not correct selection.

Have a great day,
Yuri
