Hello Laurent,
I've tried the USB capture thing... Used SnoopyPro, and because of the
size of the files i will attach them only to you personally... The
reason for the big file size is that i started capture before plugging
the cable, then i tested the video stream in Media Player Classics for a
secund or two... The reason because there are two files is that there
were two devices in SnoopyPro, with similar IDs, but somewhat similar
capture results;
USB\Vid_0474&Pid_0722&Rev_0000&MI_00,USB\Vid_0474&Pid_0722&MI_00 - USB
Video Device
and
USB\Vid_0474&Pid_0722&Rev_0000,USB\Vid_0474&Pid_0722 - USB Composite
Device
What is the deal with these two?
I also have to mention that when i plug this phone into USB, I get the
menu on it, where i select if it should work as USB camera, Storage
Device, USB Print device or Direct Comm. Transfer mode. Prior to
selecting USB camera mode there is no activity on USB, afaik...
Thanks again! I just hope we will come up with something...
