问题 string url = re["response"][0]["url"].ToString(); MediaElement mm = new MediaElement(); mm.Source = new Uri(url,UriKind.RelativeOrAbsolute); mm.AutoPlay = true; mm.Volume = 0.7; mm.Play(); But no changes, the adudio not starts.How I can resolve this? 回答1: You need to add your MediaElement to your VisualTree before playing it, since you're creating it in the codebehind. For example, assuming you have LayoutRoot and that your url is correct, this should work. string url = re["response"][0]["url

问题 I work on collecting internet radio stream files such as m3u with a link to stream inside (for example http://aska.ru-hoster.com:8053/autodj) . I didn`t find example on how it is possible to check if the link is avaliable/live . Any help is appreciated ! UPD: Maybe the main question should sound like: Could be a stream broken? If yes, will the link for that stream be still available or there will be simply 404 error in browser? If link still available to open even stream is dead, what are

问题 I've been writing a short program to redirect audio from the line in/mic to to speakers. I'm just learning most of this, but my labors have yielded what seems to almost be a working model of what I want. However, when I print the TargetDataLine buffer, it prints all 0s as if it was connected and streaming, but can't hear my input. At this point, I've studied most of the sampled package content and what was available online in forums, tutorials, and other people's code, and due to the

问题 I have a streaming music application that can play two streams simultaneously by using two separate services utilizing one AudioTrack each, on their own threads. Now I'd like to able to play more than two streams, and I guess having more services is not the way to go. Is it possible to have a single service having dynamically instantiated AudioTracks? How can I implement separate threads for each of the AudioTrack instances? How will I access the dynamically instantiated AudioTracks? 来源：

问题 We need to streaming live audio (from a medical device) to web browsers with no more than 3-5s of end-to-end delay (assume 200mS or less network latency). Today we use a browser plugin (NPAPI) for decoding , filtering (high, low, band), and playback of the audio stream (delivered via Web Sockets). We want to replace the plugin. I was looking at various Web Audio API demos and the most of our required functionality (playback, gain control, filtering) appears to be available in Web Audio API.
