Cal16x16check_vdnocnoafr1len2.avi.q10.ogv (file size: 3 KB, MIME type: application/ogg)

Description

Video of two frames: frame 1 is a 2x2 black and white checkerboard pattern; frame 2 is frame 1 reversed. This OGV file is intentionally made at 16 pixels wide by 16 pixels high in order to test media players. The video should play frame 1 for one second and then frame 2 for one second. Each square should appear completely black or completely white. The original AVI video can be found at http://84user.webs.com/tests.html named "cal16x16check_vdnocnoafr1len2.avi" and the ffmpeg2theora command used to convert the AVI to this OGV file was:
ffmpeg2theora-0.25.exe --videoquality 10 --inputfps 1 --framerate 1 --noaudio cal16x16check_vdnocnoafr1len2.avi -o cal16x16check_vdnocnoafr1len2.avi.q10.ogv
