  • Android phones: how does the video out feature work?

    - by confusedKid
    Hi, I'm searching for android phones that can use video out to the tv for a research project. I'm considering the HTC Touch Pro. Is there anything I have to do specifically to get the video out to work (for displaying my app on the tv)? or will the phone just display a running app on the tv without extra work? Thanks, I hope the post made sense =)

  • Android: how to obtain AssetManager without reference to Context?

    - by ab11
    I have a Class that needs to obtain a reference to it's application's AssetManager. This class does not extend any sort of android UI class, so it doesn't have a getContext() method, or anything similar. Is there some sort of static Context.getCurrentApplicationContext() type of method? To clarify: my class is intended to be used like a library, for other applications. It has no associated AndroidManifest.xml or control over the context which is calling it.

  • How to load src in html5 Video tag from JavaScript?

    - by luis_laurent
    Here is the thing, I'm working with ASP.NET and I'm using this particular SignalR library to broadcast a video to my clients, but as far as I know I can not stream video because signalR is a messaging system and it is not intended to stream video, files or things like that. Now what I am trying to do is to split the video into buffers that is Base64-encoded into a string, then on the client I am decoding this string and I am trying to load it into the source of a Video tag. Here I show you what I am doing on the client: HTML Code: <video id="myVideo"> <source id="video_source"> </video> Javascript Code: //here somehow I am getting the string with the base64-encoded video function playVideo(message) { var myVideo = document.getElementById("myVideo"); var mySource = document.getElementById("video_source"); mySource.setAttribute("src", getEncodedVideoString("avi", message)); myVideo.load(); myVideo.play(); }; // here I am formatting and concatenating the string for my source attribute function getEncodedVideoString(type, file) { return 'data:video/' + type + ';base64,' + $.base64.decode(file); } Well as you can see, at the moment I'm facing a scenario a little weird, but I already have the video encoded on the client, now I just need to find out the way to reproduce that video. And here is when my question comes up, does any one has done something like this before, or you have any idea or suggestion to do that? P.S I am using this jquery-base64 library to decode my string
