video-streaming

问题 I would like to build a web application that lets two peers see and hear each other using video and audio streaming with HTML5 and no plugins (except for IE, that I pretend to use getUserMediajs to use a flash fallback). I also want to transmit that data using NodeJS but I have no idea where to start. In an example: Peer A <---> Node JS <---> Peer B I'm interested in this Peer 2 Server 2 Peer approach instead of a Peer 2 Peer solution like PeerJS because: 1) I think it will be more compatible

问题 I am new to ROS. I am working on a video feed from ARDRONE but I am not able to stream the video. Should I have to change the topics in publisher and subscriber to stream the video ???

问题 is it possible to stream (previously recorded and/or live) video to many Microsoft Lync SDK webbrowser clients? Thanks in advance, Etam. 回答1: The short answer is No - not without some pain. The long answer depends on your exact scenario. If you can control the client build, and are able to ensure Lync is installed, then you should be able to automate Lync from the Silverlight app to connect to the conference that is hosting the video content you want to display. With this solution, it will be

问题 I've m3u8 file with all the TS files. MPMoviePlayerController play them fine via http request on the streaming server. But I'd like to get the files locally in order to play them again later without any connection. I managed to download m3u8 file and all the TS files locally on my device, I edited m3u8 files to point to local .ts instead of http ones, but I can't read them from this emplacement. (VLC can do it well) Is there a way to download the segments while playing (to avoid 2 downloads)

问题 I'm writing app in symfony2 and I have a problem with video streaming. If one action takes a long time to execute - for example 1 minute , the whole app is frozen (when opened in second tab) and must wait for end of that execution.
