The video server should be rewritten so it's using Twisted

[devos50]

Our current video server is dependent on VideoPlayer which in turn is dependent on the wx GUI. Moreover, the video server contains a lot of blocking code (time.sleep and threading.event occurrences), making the reactor and Tribler block when the user watches a video.

This video server should be rewritten in Twisted, making use of a static File object. The following should happen when a request to this video server is made:

• we should intercept the range in the request. This range should be converted to the offset of the requested file in bytes. If these bytes are available, just return the File object immediately. If they are not available, set the download priority of these bytes to the maximum and return a deferred that fires when these bytes are available.
• also, when a request comes in, we should check which file is requested and set the priority of other files on this download to zero.

@synctext So until this complete rewrite is done, we don't have a video server that will work on Android.

ai, bummer. @brussee
have you browsed the previously running code of various other projects? Three groups got it working.

One I could find quickly:
https://github.com/synctext/bsc-project/blob/master/Work/vlc-android/src/com/tudelft/triblersvod/example/TorrentVideoPlayerActivity.java

Seek is more complex then linear download. better then download full and play. But first document existing code...

Obviously: https://github.com/Tribler/tribler-android

tsap codebase with rpc calls for streaming:

btw refreshing to see all this old code..

@brussee I'm pretty sure that the video player works with the Twistd plugin (recently checked). I was probably confused about the 'VideoPlayer' class being dependent on the GUI but iirc, it works without. Can you try it? Just use curl or wget to test it.

Probably fixed in #5301
