ksvideosrc generates slow and dark input

Ilya Aleshkov
Hi,

ksvideosrc generates extremally slow (1 fps!) and dark input for laptop’s integrated cameras (Microsoft Surface Pro 6). But for external webcams everything works great.
Any suggestions?

Thanks,
Ilya

I'd like to provide more details:

My test pipeline:

gst-launch-1.0 ksvideosrc ! video/x-raw,format=NV12,width=640,height=480,framerate=15/1 ! videoconvert ! autovideosink

gst-device-monitor-1.0 output about laptop’s front camera:

Could it be a timestamp issue, as per the caps, this resolution/rate
should not be a problem. Maybe do a quick test disabling frame
synchronization ? (autovideosink sync=0)

I wonder what IANV color format is, this isn't mapped in libgstvideo
for sure, so this format won't be usable.

Hi Nicolas,
 
Maybe do a quick test disabling frame
synchronization ? (autovideosink sync=0)

Thank you! Unfortunately, it doesn't change anything.
