No need to download the video (which requires a Motion JPEG codec), here are a couple of frames :-
Just like the initial splashscreen (that had too small a buffer size), we have three columns and an interlaced effect.
For those interested, here is current zebra code :-
int gui_osd_draw_zebra() {
unsigned int v, s, x, y, f, over;
color cl_under=conf.zebra_color>>8, cl_over=conf.zebra_color&0xFF;

if (!buf) {
buf = malloc(screen_size);
scr_buf = vid_get_bitmap_fb();
}
if (buf) {
++timer;
img_buf=((mode_get()&MODE_MASK) == MODE_PLAY)?vid_get_viewport_fb_d():vid_get_viewport_fb();
viewport_height = vid_get_viewport_height();
