ChromiumOS Yet Another V4L2 Test Application

cros-yavta is a V4L2 test application (our main usage is camera testing). It is
based on another open source project, yavta, http://git.ideasonboard.org/yavta.git.

== Features
Inheritance from original yavta:
- pure command line tool
- open/close devices; start/stop streaming
- specify resolution, framerate, format, etc.
- get/set control values
- dump raw frames to file

More features:
- display on X window
- simulcast
- dump raw frame to ivf format
- dump decoded frame to ppm or y4m format
- builtin mini web server
  + some basic features from web interface
  + streaming webm (for VP8 format)
- remote server

== Sample usage

Output frames on the screen
$ ./yavta --output --capture /dev/video0

Output mjpeg frames
$ ./yavta --output --capture --format mjpeg /dev/video1

Output 100 frames on the screen and dump to file
$ ./yavta --output --capture=100 --dump /dev/video0

--port 9999
Hint: You may need to change firewall rule to accept remote connection.
