English: Video of two frames with aspect ratio 4:3: frame 1 is a 2x2 black and white rectangular checkerboard pattern; frame 2 is frame 1 reversed. This OGV file is intentionally made at 64 pixels wide by 48 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 rectangle should appear completely black or completely white. The ffmpeg2theora command used to convert the AVI to this OGV file was:
ffmpeg2theora-0.25.exe --videoquality 10 --framerate 25 --noaudio cal64x48check_vdfr1to25len2.avi -o cal64x48check_vdfr1to25len2.avi.q10fr25.ogv |
