Hello Mike, Is there an existing roadmap to address these issues? regards, Koen ----- Oorspronkelijk bericht ----- Van: "Hans Verkuil" <hverkuil@xxxxxxxxx> Aan: "de witte koen" <de_witte_koen@xxxxxxxxxx>, linux-media@xxxxxxxxxxxxxxx Cc: "Mike Isely" <isely@xxxxxxxxx> Verzonden: Dinsdag 6 september 2016 12:00:06 Onderwerp: Re: v4l2-ctl does not show all parameters for HVR-1900 On 09/05/16 21:01, de_witte_koen@xxxxxxxxxx wrote: > > 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. The problem here is that the pvrusb2 driver predates the V4L2 control framework for handling controls. Instead it has its own implementation and that is known to be buggy. For a variety of reasons it is not easy to rework this driver to use the control framework. I've CC-ed the maintainer, perhaps he can make a patch that at least exposes these controls through the QUERYCTRL ioctl (they don't seem to turn up when enumerating the controls, which is why the above fails).
