Tool/software: Linux

Hello, i have omap-l138 and tvp5150 and i want to capture a frame with yavta or gstreamer (or anything that works)

my SDK version is mcsdk_1 and using linux 3.3.0.

after some tries and changes (this link)  finally i am able to capture image and video with gstreamer and yavta.

now my problem is that captured image is half size in height.

for example i caputerd a frame with this command:

gst-launch v4l2src num-buffers=1 ! jpegenc ! filesink location=ti.jpg

the image format is UYVY in sd resolution.

i attached raw image also.(i changed postfix to 123 because cant upload yuv file )

can you help me to find out the problem?

thank you.
