Seekbar preview ・ シークバープレビュー

N.B: The final montage file must be created with exactly 100 thumbnails.
注意: 最終的なモンタージュファイルは正確に100個のサムネイルで作成する必要があります。

Take screenshots with FFMPEG・ FFMPEGで画面キャプチャがする

ffmpeg -i sintel_trailer-720p.mp4 -f image2 -bt 20M -vf fps=100/VIDEO_LENGTH_IN_SEC -aspect 16:9 %03d.jpg

For example, Sintel trailer is 52 seconds length.
たとえば、Sintelの予告編の長さは52秒です。

ffmpeg -i sintel_trailer-720p.mp4 -f image2 -bt 20M -vf fps=100/52 -aspect 16:9 %03d.jpg

Generate montage file with ImageMagick・ ImageMagickでモンタージュファイルを生成する
