For example, for a 30 seconds duration video, we'd like to analysis the I-frame around 00:00:02, 00:00:15, 00:00:28.

问题 I'm using the video.js plugin. I'm using ajax to load in another bunch of videos from another page but I want to call the javascript again to perform the skinning again.

问题 I'm trying hard to get the modification date from a MP4 file hosted on my server. I tried the following library: ffmpeg -i video.mp4 Without any luck.
