28/**
29 * Fragment demonstrating the use of {@link android.support.v17.leanback.app.VideoSupportFragment} to
30 * render video with playback controls. And demonstrates video seeking with thumbnails.
31 *
32 * Generate 1 frame per second thumbnail bitmaps and put on sdcard:
33 * <pre>
34 * sudo apt-get install libav-tools
35 * avconv -i input.mp4 -s 240x135 -vsync 1 -r 1 -an -y -qscale 8 frame_%04d.jpg
36 * adb shell mkdir /sdcard/seek
37 * adb push frame_*.jpg /sdcard/seek/
38 * </pre>
39 * Change to 1 frame per minute: use "-r 1/60".
40 * For more options, see https://wiki.libav.org/Snippets/avconv
41 *
42 * <p>
43 * Showcase:
44 * </p>
45 * <li>Auto play when ready</li>
46 * <li>Set seek provider</li>
47 * <li>switch MediaSource</li>
48 * <li>switch PlaybackGlue</li>
