• Get a specific frame from a video using javascript

  25 mars 2016, par Sebi55

  Is there the possibility to somehow get a specified frame from a video using javascript ?
  Most of the questions I found always talked about getting the current frame of a video which is of course no problem but is there a way to get a frame of a video which is not the current one ?
  It would be much easier I think then using ffmpeg from my point of view.
  I actually didn’t find anything about this topic online but I think it is just not possible but maybe someone got an idea.

  doc/default.css + doc/t2h.init : New styles
  The main motive of this commit is to make the offline copy of the HTML doc as
  
  pretty as the online (ffmpeg.org) one. This also introduced new styles for
  
  <h2> to <h4>.

• trying to figure out what's wrong in the code using ffmpeg.exe

  5 octobre 2013, par timmack

  I'm trying to upload videos and convert it to flv format as well as capturing image as thumbnails.I'm using visual web developer 2008 express edition.I've done so many research online and found something using ffmpeg.exe so I've downloaded an ffmpeg.exe and has tried so many codes but unfortunately I'm still unable to make it work.I want to save the converted video file to a certain folder in my server as well as the captured image as for its thumbnails after uploading the video.I'm not sure if the ffmpeg.exe has the problem or my codes but I suspect it's in my codes.I need somebody to help me find out what's something missing on my codes to make it work. Here's my codes below for your reference. Thanks
