Effects with GStreamer:

The following error message may occur in rare cases due the current 
GStreamer version:
(gst-launch-0.10:1125): WARNING **: videoscale0: size 315359 is not 
a multiple of unit size 921600

The effect is, that sometimes the first buffer in the GStreamer 
pipeline is incomplete. This is a problem of GStreamer. 
With an application software this effect will not exist.

- USB-CAM-004H (with UVC Firmware update)
- USB CAM 104H (with UVC Firmware update)
