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?
