* All pods have an index of all videos of the network (name, origin pod url, small description, uploader username, magnet Uri, thumbnail name, created date and the thumbnail file). For example, a test with 1000000 videos with alphanum characters and the following lengths: name = 50, author = 50, url = 25, description = 250, magnerUri = 200, thumbnail name = 50 has a mongodb size of ~ 4GB.

user asks its pod -> user pod asks origin video pod -> origin video pod responds with the informations -> user pod responds to the user (and puts in cache the informations ?). We could extend this scheme with other informations
|
||||
* Redondance: if the origin pod is down, the video is not accessible anymore (no tracker/seeds). We could imagine a redondance between pods that keep seeding the video
|
||||
* Server could transcode the video to lower qualities (cost in CPU and disk space)
|
||||
* Server could seed at the demand: for now the server seeds all the videos but it has two drawbacks:
|
||||
- Seeding has a cost (if a pod has 1000 videos it could be an issue)
|
||||
- After a restart the server has to reseed all the videos (with 1000 videos it could long)
|
||||
If this solution is choosen, the frontend has to notify the origin pod that it has to seed the video
|
||||
* Add subtitles to videos
|
||||
* Avoid stocking friends URL schemes (http/https)

There already is a frontend (Angular 2) but the backend is a REST API so anybody can build a frontend (Web application, desktop application...).

The backend uses bittorrent protocol, so users could use their favorite bittorrent client to download/play the video with its torrent URI.

The seperate Electron process has the goal to seed videos through WebRTC because WebRTC directly in NodeJS is not usable for now.
|

A video is seeded by the server throught the [WebSeed](http://www.bittorrent.org/beps/bep_0019.html) protocol (HTTP).

When a user uploads a video, the rest API asks the Electron process to seed it (communicate with IPC) and then adds it to its Mongo database.
