Hi,
I've got same issue with Logitech C910 as it was described in 2011:
http://www.lavrsen.dk/foswiki/bin/view/Motion/SupportQuestion2011x01x09x193606
Anyone knows if a solution have been developed for this issue?

Looks like the MJPEG is good, but some junk also appears in the buffer,
which does not affect the picture.
By changing motion code I was able to make Logitech C910 working:
diff --git a/video_common.c b/video_common.c
index 54569c6..f98154f 100644
--- a/video_common.c
+++ b/video_common.c
@@ -394,7 +394,7 @@ int mjpegtoyuv420p(unsigned char *map, unsigned char
*cap_map, int width, int he
if (ret == 1) {
MOTION_LOG(CRT, TYPE_VIDEO, NO_ERRNO, "%s: Corrupt image ...
continue");
- ret = 2;
+ ret = 0;
}
return ret;
}
Basicaly, motion should ignore the decode warning.
I will report this issue in Mr-Dave fork
Thanks

Hello
Thank you but I found another solution. Now I use Picamera which use
python.
So now I can record in full HD and at the same time in 320x200 (for
streaming) and I can extract images (1 per minutes).
After I use vlc for streaming the flux on web pages.
It is very easy to use.
Thank you
