I have a website like Youtube site. In here I gonna manage videos(playlist, commit, etc) I gonna add some function for video player in my website. Number of views / My lists: XX or more Number of comments: XX or more Time: short-----long-unlimited Posting period: old-new-latest Intuitive operation feeling can be realized Of course, it is the best for those who can enter the date directly and narrow down Example "November 11, 2011-February 22, 2010" Another good thing is a free (key) word search This can search not only the title of the video but also the tag at the same time (of course you can also search by following the tag) Another caption search. This is also on YouTube Contributors can write commentary, etc., but it is searchable Here is a reference example (the mark is on the right of the site) [login to view URL] [login to view URL] The search function is fair. These are not on YouTube We can accept as many questions as you want about the specifications. 1. The more the number of playbacks, the number of my lists (bookmarks), and the number of evaluations, the better. 2. The number of comments should generally be large, but it depends on the content. [login to view URL] is better to be able to specify the video time, posting time, and the amount of comments flowing (e.g., "From here to here" with ↓ ↑) (Image of choosing like a questionnaire form of birth date) Is it such a place for the time being? Of course, the higher the rating, the better, and the lower the rating, the better. And tags that users can register at will It would be perfect if you could search for captions, keywords and comments in the video Please read carefully and if you can do it, please let me know.
