Download only a part of the video in the server
19 août 2013, par whiteletters and blankspacesI am building a web application for creating animated gif from youtube videos. These animated gifs will be fews seconds long, but may come from very long videos hosted in Youtube.
After reading and reading, It looks like I should first download the whole video in server, then cut the required part, ( probably convert it), then process it to generate the gif using ffmpeg for example.
Could you please tell me :
Does the whole video should be necessarly downloaded in server ? Or there is a way to ask my server and Youtube Server to exchange only the requested (very small) part of the video ? I think that downloading the whole video will result in bad resources usage, especially in concurrency environnement which will affect performance in my one-server infrascrucure.
What are the alternatives of downloading the video (or part of video) to achieve such goal ? Is there a client side solution for storing data and using similar ffmpeg functionalities ?
