Hi all,
I have a Trust WB-5400, which apparently is the same as a Medion
MD85572.
Both are 0c45:624e and have a SN9C201 bridge and SOI968 sensor.
(Hence I added the Trust to the list-of-known-microdia-webcams.)
According to the project status, it should be supported.
However, I only get flickering output: some frames are ok, but lots
are garbled.
In such a garbled frame, part of the image is in the right place, but
other blocks of the image (remains of the previous frame?) are at a
wrong position.
I would post a screenshots, but I didn't find how to attach files and
apparently I can't email directly to the group?
Anyway, this is mplayer output:

Any ideas?
