I just modified a V4L2 test app on AR.Drone to dump one video frame from:MAPGPS wrote:/dev/video0 and /dev/video1 are V4L2 camera interface, with YUV420 format.
front camera (/dev/video0) with 640*480
bottom camera (/dev/video1) with 176*144
And use YUV Player Deluxe:
http://www.yuvplayer.com/" onclick="window.open(this.href);return false;
To display the raw YUV video frame in file test.yuv on Windows XP.
The raw image of 640*480 has nice resolution, far better than what I have ever seen from my AR.Drone camera!
Code: Select all
# cd /data/video # killall program.elf # ./v4l2_test driver = p6_camif.0, card = p6_camif, version = 5, capabilities = 0x4000001 Buffer count = 4 Buffer: index = 0 # ls -l *.yuv -rw-r--r-- 1 root root 460800 Jan 1 00:01 test.yuv #
