[FFmpeg-user] External UVC Camera Video Streaming/Image Capturing using ffmpeg

[s.rawat]

Hi,
I am trying to perform the image /video capturing using ffmpeg for an
external uvc camera connected to my arm device/board.I have compiled the
source code using ndk5 and i have got ffmpeg lib whcih I have placed in the
system/lib folder and issuing the following command

ffmpeg -y -t 25 -f video4linux2 -r 15 -s 320*240 -pix_fmt yuyv422 -i
 /dev/video1 -an -f avi Test_QVGA1.avi

But I am the following output/error(see in *Bold* at last) -->

My aim is to stream the video up to the Android UI and display it using the
android media player.
It would be great  if some one could guide me some direction towards this.
Thanking you with great faith and hope in this community.
