hi,

I dont know whether it is the right forum to post this. I not I am sorry.

I am using qt-gstreamer to record and stream webcam. I am using usb camera.
 In x86 I am using ubuntu12.04 and i can able to capture the video using
webcam.

and  i can stream webcam in x86.
 Now coming to ARM.


I cross-compiled qt-gstreamer for ARM cortex-a8 procesor(TIAM335x). I am
running linux in arm.

when i am trying to record from webcam i am getting following error.

in terminal

root at Wega-AM335x:~:$ ./recorder -qws

recorder:749): GStreamer-CRITICAL **: gst_caps_get_structure: assertion
`GST_IS_CAPS (caps)’ failed

(recorder:749): CRITICAL **: No headers or buffers on pad
oggmux0:sink_1538339170

I am not able to stop the video. when i give ctrl+c. the file is empty file
without any data.

And when i am playing the player

In terminal

root at Wega-AM335x:~:$ ./player -qws
start: could not open overlay


In lcd
 video is palying but i cant see the video.

I am saying  video is playing because playing time is moving. I could able
to forward the video playing time . But i cant see the video.

Thanks & Regards
