android r10.3 + adv7180 have "combing and feature artefacts" issue

Discussion created by Jacky Huang on Mar 25, 2012

By default,  after porting the adv7180 driver to android r10.3 on mx53, you will get the "rolling screen".

we solve the "rolling screen" issue with  teammate's effort .

However,  we get the "combing and feature artefacts" issue.

so, I porting the unit_test  mxc_v4l2_tvin to android platform and run by android console,

I found the mxc_v4l2_tvin test program can run normally, there is no "combing and feature artefacts" issue!!!

so I compare the ioctl calling between the mxc_v4l2_tvin and android r10.3 camera hal + overlay hal,

then I add the ioctl which isn't appear in the android hal but not appear in the mxc_v4l2_tvin to the android hal.

However,  there is no any improvement.

I can't find the key point about this issue.

anyone can get me some suggestion?


Thanks advance!
