Hi all,
I have been trying to integrate a Logitech webcam (Pro 9000 or c200) into an
embedded linux environment. It is running 2.6.20 kernel on MIPS arch.
# cpuinfo
system type : INCAIP2
processor : 0
cpu model : MIPS 4Kec V4.0
BogoMIPS : 130.66
wait instruction : yes
microsecond timers : yes
tlb_entries : 16
extra interrupt vector : yes
hardware watchpoint : yes
VCED exceptions : not available
VCEI exceptions : not available
I can successfully compile and load v4l2 modules and uvc. However, when I
try to use an application to capture video (ffmpeg or famous v4l2 video
capture example) it stucks and gives no repsonse ("select timeout"). What I
get from syslog and dmesg are messages like (lots of them):
<7>uvcvideo: Dropping payload (error bit set).
<7>uvcvideo: Dropping payload (error bit set).
<7>uvcvideo: Dropping payload (error bit set).
<7>uvcvideo: Dropping payload (error bit set).
<7>uvcvideo: Dropping payload (error bit set).
<7>uvcvideo: Dropping payload (out of sync).
<7>uvcvideo: Dropping payload (out of sync).
<7>uvcvideo: Dropping payload (out of sync).
<7>uvcvideo: Dropping payload (out of sync).
<7>uvcvideo: Unknown status event type 10.
<7>uvcvideo: Unknown status event type 4.
Do you think the kernel version is too old ? I googled for the error
messages but could not find any usable information. I need to solve the
problem soon. Thanks for your help.
