Subject: v4l2-ctl does not show all parameters for HVR-1900
Date: Mon, 5 Sep 2016 21:01:25 +0200 (CEST) [thread overview]
Message-ID: <611282171.287911096.1473102085377.JavaMail.root@telenet.be> (raw)
In short:
Is it normal that I can use the v4l2-ctl command to adjust brightness, saturation, hue, etc but not to adjust more interesting parameters like bitrate, aspect ration, etc?
Working:
pi@raspberrypi:~ $ cat /sys/class/pvrusb2/sn-4034395926/ctl_hue/cur_val
0
pi@raspberrypi:~ $ v4l2-ctl -c hue=1
pi@raspberrypi:~ $ cat /sys/class/pvrusb2/sn-4034395926/ctl_hue/cur_val
1
Not working:
pi@raspberrypi:~ $ cat /sys/class/pvrusb2/sn-4034395926/ctl_video_bitrate/cur_val
6000000
pi@raspberrypi:~ $ v4l2-ctl -c bitrate=6000000
unknown control 'bitrate'
pi@raspberrypi:~ $ v4l2-ctl -c video_bitrate=6000000
unknown control 'video_bitrate'
pi@raspberrypi:~ $ v4l2-ctl -c ctl_video_bitrate=6000000
unknown control 'ctl_video_bitrate'
the pvrusb2 driver has created all sysfs parameters and they work using the "echo" method but I thought this was also the purpose of the v4l2-ctl command, correct?
Some details, let me know if you need more.
Regards,
Koen
