i.mx53 ADV7180+Gstreamer Video Scrolling

[tomorroworld]

We used ADV7180 to capture the video signal of  one PAL camera.

When run the mxc_v4l2_tvin.out in the unit_tests folder, the video was very good and stable. 

But if using the gstreamer pipeline to streaming/recording/reviewing the video, the video always scrolled vertically. Can you help me for this problem? Thank you!

My gstreamer pipeline:

gst-launch-0.10 -v mfw_v4lsrc capture-width=720 capture-height=576 ! queue ! mfw_vpuencoder codec-type=std_avc bitrate=4000 gopsize=10 ! avimux  ! queue ! filesink location=adv7180_camera.avi sync=false async=false 

And the video recorded is attached.

Maybe it´s the difference between PAL and NTSC, not the preview.

Thank you! Jacky! It worked well!

I am confused why the video turned to be stable when the preview was set?

Thanks again!

you can try the command as below 

gst-launch-0.10 -v mfw_v4lsrc capture-width=720 capture-height=576 sensor-width=720 sensor-height=288 typefind=1 preview=1 preview-width=720 preview-height=576 bg=1

as I deduce, you video source is PAL,  the command as above I succeed for NTSC video source

yes! All related topics on imxcommunity had been read through. But I still have no idea how to solve the problem.

Sorry for my poor english understanding. Maybe I have not catch the ideas of the topics. 

Do I need to modify the ADV7180 driver?

Thank you!

There is a lot of imx53 + ADV7180 topics on imxcommunity. 

Would it be enough?
