Hi all,
when i query available video device nodes with “v4l2-ctl --list-devices” then some times it is showing encoder and some times it using decoder as shown below
This is happening on reflashing the bootimage.
root@linaro-alip:~# v4l2-ctl --list-devices
Qualcomm Venus video decoder (platform:qcom-venus):
/dev/video0
/dev/video1
root@linaro-alip:~# v4l2-ctl --list-devices
Qualcomm Venus video encoder (platform:qcom-venus):
/dev/video0
/dev/video1
As i’m working on venus decoder driver this is making me annoyed since i’m concerned only with decoder.since the video device node sometimes representing encoder, the decoder ioctls calls are not happening thus it forcing me to reflash the bootimage again and again till i can see the decoders device node.
anyone knows,what might be the reason for this?
Regards,
Laxman
