Hi Androidphan,
My Beagle(ARM based board) is working camcorder and camera app with
your v4l2 camera.
Points in my environment,
1. change permission of video device. (or change owner?)
chmod 666 /dev/video0
2. free space of 1st dos partition on the SD card is made 4Gbyte or
less.
AuthorDriver and MediaRecorder are failed with max-filesize error.
3. change resolution to 352x288 in CameraHardware.cpp.
Thank you Androidphan!
Regards,
Atsuo
