/**
 * Fragment demonstrating the use of {@link android.support.v17.leanback.app.VideoSupportFragment} to
 * render video with playback controls. And demonstrates video seeking with thumbnails.
 *
 * Generate 1 frame per second thumbnail bitmaps and put on sdcard:
 * <pre>
 * sudo apt-get install libav-tools
 * avconv -i input.mp4 -s 240x135 -vsync 1 -r 1 -an -y -qscale 8 frame_%04d.jpg
 * adb shell mkdir /sdcard/seek
 * adb push frame_*.jpg /sdcard/seek/
 * </pre>
 * Change to 1 frame per minute: use "-r 1/60".
 * For more options, see https://wiki.libav.org/Snippets/avconv
 *
 * <p>
 * Showcase:
 * </p>
 * <li>Auto play when ready</li>
 * <li>Set seek provider</li>
 * <li>switch MediaSource</li>
 * <li>switch PlaybackGlue</li>
