Re: [Linux-uvc-devel] webcam MANTA MM353 Plako on chip ARK3188
Andrew Hi,
By default vlc uses libv4l, just like most other software, when this
fails it reverts to direct v4l2 access, (you probably should also
check your libv4l version and update it if needed)
vlc seems to be able to open a MJPG stream after a few failed
attempts, I can't really understand why it fails with the other
software (it returns a I/O error when trying to set the stream
format).
Can you increase the driver verbosity and check for error messages with dmesg ?
Regards,
Paulo
2010/6/23 Andrew V Kuzmin freeg...@mail.ru:
Got the latest version, but error still happened (logs below)
Have you seen the vlc logs?
It seems that cam not supported by гмс drivers - direct kernel v4l2 -
what does it means?
