Re: flicker/jumpy at the bottom of the video

2009-12-23 Thread Olivier Lorin
Hi,

one of the sensors managed by the gspca_gl860 has some weird
resolutions : 800 x 598 and 1600 x 1198. To set these resolutions to
800 x 600 and 1600 x 1200 causes a flickering effect because of both
missing lines of data from the sensor. Thus a stupid question, does
the resolutions are these chip are well known ?

 But otherwise there is no issue with video.

 Hello Purush,

 Sorry for the delay. We know that some webcams with Z-Star chips have
 such a problem, but it is a hardware problem and we did not find yet a
 way to fix it correctly...

 Best regards.

flicker/jumpy at the bottom of the video

2009-11-23 Thread Purushottam R S
Hi ,

I am using latest gspca driver from dvb for camera driver. But I see bottom of 
the video has flickering/jumping effect.

I have Zippys web camera, which is from Z-Star.  I have loaded the following 
drivers.
1. gspca_zc3xx 44832 0 - Live 0xbf01f000
2. gspca_main 23840 1 gspca_zc3xx, Live 0xbf014000
3. videodev 36672 1 gspca_main, Live 0xbf006000
4. v4l1_compat 14788 1 videodev, Live 0xbf00

But otherwise there is no issue with video.

I tested using gst-launch pipeline.

Purush
