I want to mimic the bing video preview functionality, with a thumbnail preview, then onMouseOver, load and play a video file. I plan to use VideoJS (html5 + flash) for the video playback. I need to use ffmpeg to produce these video files.
How can I create a mp4 preview with video only, which contains 1s of every other minute of the full clip, and shrink resolution to a fixed width (maintaining aspect ratio, preferably with zoom crop) using php + ffmpeg command line?
I'm assuming it can be done somehow along the lines of cutting 1s clips, then combine the smaller clips, and re-encode for a final rescaled output.
*Edit: Using ffmpeg is a design requirement. Pulling out 1s clips, should be fairly easy, but combining them seems to be somewhat complex with ffmpeg. I don't want cycling thumbnails, I want a video preview which contains a number of 1s clips. Eg. runtime in seconds: 100-101, and 200-201 combined in a heavily compressed clip. I am asking for a command line example of how to do this in an efficient manner.
