Transcode MOV to Theora 1.You have a somehow acquired QuickTime MOV file: "example.mov". 2.Dump YUV and WAV from MOV: "mplayer -ao pcm -vo yuv4mpeg example.mov" => audiodump.wav, stream.yuv 3.Transcode to theora: "encoder_example -o example.ogg audiodump.wav stream.yuv" => example.ogg Create Annodex files 1.Write CMML file: "example.cmml" 2.Encode Annodex: "anxenc example.cmml -o example.anx" => example.anx
