I have done a lot of search on Google intend to find the anwser,but unlunkily with no results. I want to watch some videos stored on my PC from my android phone. I have been using DAAP to listen my music. Is there a similar DVAP (Digital Video Access Protocol)?
While DAAP can actually handle video as well as audio, in your situation it would be best to look for a UPnP server for the PC, and a UPnP client for Android. There is a lengthy list of both on Wikipedia.
