The SproutVideo PHP SDK by SproutVideo wraps the API to access video hosting features. Developers can install with composer and GitHub. Resources present how to initiate development with videos, tokens, tags, and playlists.
The most popular video API is about to become more popular. As just announced by Googe's Jim Patterson on the YouTube blog, YouTube Everywhere, the YouTube API has just been upgraded with some very powerful new features.
Taking advantage of APIs is a quick and inexpensive technique for a business so long as those APIs are available and remain constant. Changes happen to APIs all the time and this is the story of Stitch, a company that found a way to succeed, despite the uncertainties inherent to the API economy.
You can now use the YouTube API to access and create captions for your videos. That means you could let your site visitors refine the transcript to videos you own, or create their own versions of the caption.
