Hi,
I am using qt-everywhere-opensource-src-4.8.5 and cross compiled it for ARM Ti-Am335x processor.
I am able to run some qt example & demos . Right now can I inteface a usb camera in qt4.8.5.
I am running Linux on development board and Ubuntu 12.04 on my system.

Hi,

You should have a look at the QtMultimedia module for that.

Hope it helps

root@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@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.
