问题 I can't find a way to do this. is it possible to control the media stream that is current playing on chromecast, like youtube, video app, music app, or whatever from a generic Android application?

问题 I'm new to Azure and to analytics. I'm trying to understand streaming alert rules engine. I have used some sample data as input and have queries to filter data. However i'm not sure of what rules engine means, is it just queries or is there anything more to it and is there a way we can have all rules in one if yes, how? 回答1: The main way to define logic for ASA is to use SQL, which provide a way to define rules with SQL statements (e.g. SELECT DeviceID ... WHERE temperature>50). Multiple

问题 I have access to a Hadoop cluster that has base R (2.14.1) but no additional packages installed in every node. I've been writing base R mapper and reducer streaming scripts to get around the fact that I have no additional packages.

问题 We're using WCF to build a simple web service which our product uses to upload large files over a WAN link. It's supposed to be a simple HTTP PUT, and it's working fine for the most part.

问题 I am trying to use a RTSP stream from an IP camera as video input source for various applications on Windows (eg. skype). The only solution I have found so far is using " webcam 7 ", an application that fetches RTSP stream and creates a virtual driver that registers in system as webcam and that any application can then use. Unfortunately, this application often becomes unstable and might crash randomly. Are there any alternative/better ways for achieving this? 回答1: Create your own DirectShow

问题 We're using a FileStreamResult to provide video data to a Silverlight MediaElement based video player: public ActionResult Preview(Guid id) { return new FileStreamResult( Services.AssetStore.GetStream(id, ContentType.Preview), "application/octet-stream"); } Unfortunately, the Silverlight video player downloads the entire video file before it starts playing. This behavior is expected as our Preview Action does not support downloading partial content. (side note: if the file is hosted in an IIS

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. Where is the problem? //EDIT public function streamAction($fileName) { $user = $this->get('security.context')->getToken()->getUser(); $request = $this->getRequest(); $uid = $request->get('uid') != 'null' ? $user->getId() : $request->get('uid'); $libPath = $this->
