[AG-TECH] AG in a virtual machine

[Jon Johansson]

Hi Doug,

When I select the V4L2 device and then select Transmit, I get:
jonj at ubuntu:~$ vic 234.5.6.7/12000
Attached to V4L device: V4L-USB Camera (046d:08ad) /dev/video0
Attached to V4L2 device: V4L2-USB Camera (046d:08ad) /dev/video0
Segmentation fault

When I select the V4L device and then select Transmit, I get:
jonj at ubuntu:~$ vic 234.5.6.7/12000                              
Attached to V4L device: V4L-USB Camera (046d:08ad) /dev/video0  
Attached to V4L2 device: V4L2-USB Camera (046d:08ad) /dev/video0
ioctl VIDIOCSYNC: Invalid argument                              
Syncerror SyncCount 1                                           
ioctl VIDIOCSYNC: Invalid argument                              
Syncerror SyncCount 1                                           
ioctl VIDIOCSYNC: Invalid argument                              
Syncerror SyncCount 1
...

and there is a video stream displayed (NTSC) but it's green as
shown in the attached image. Trying Pal and Secam doesn't change
this.

With a bit more care adding services to the venue client, 
I can add either a VideoService, or a VideoProducerService pointing
at the V4L source, but the producer vic doesn't start - I do get
a consumer vic though, just "Waiting for video...". 
Disabling and enabling the video results in a vic window appearing
briefly, just a flash of the frame, and then it disappears. 

Thanks,
Jon.

Hi Jon,

What is the console output of vic? i.e. start vic on the command-line
and then click transmit in the GUI, e.g.:
   vic 234.5.6.7/12000

The error output might give a hint.
