My Understanding of HTTP Polling, Long Polling, HTTP Streaming and WebSockets

由 醉酒当歌 提交于 2019-12-17 22:03:17
问题 I have read many posts on SO and the web regarding the keywords in my question title and learned a lot from them. Some of the questions I read are related to specific implementation challenges while others focus on general concepts. I just want to make sure I understood all of the concepts and the reasoning why technology X was invented over technology Y and so on. So here goes: Http Polling: Basically AJAX, using XmlHttpRequest. Http Long Polling: AJAX but the server holds on to the response

jQuery read AJAX stream incrementally?

由 陌路散爱 提交于 2019-12-16 20:18:55
问题 I have read this question but it doesn't exactly answer my question. Unfortunately, it looks like things have changed in in the XHR object since I last looked at AJAX, so it is no longer possible to directly access responseText before it is finished being populated. I have to write a page that uses AJAX (preferably jQuery, but I am open to suggestions) to retrieve CSV data via HTTP from a server I have no control over. The response data could be quite large; a megabyte of text is not uncommon

Efficiently reading lines from compressed, chunked HTTP stream as they arrive

由 余生长醉 提交于 2019-12-14 00:21:17
问题 I've written a HTTP-Server that produces endless HTTP streams consisting of JSON-structured events. Similar to Twitter's streaming API. These events are separated by \n (according to Server-sent events with Content-Type:text/event-stream) and can vary in length. The response is chunked (HTTP 1.1 Transfer-Encoding:chunked) due to the endless stream compressed (Content-Encoding: gzip) to save bandwidth. I want to consume these lines in Python as soon as they arrive and as resource-efficient as

Mixed Video Type Content queued in an AVQueuePlayer on iPhone

由 余生长醉 提交于 2019-12-12 05:35:36
问题 I'd like to start of by apologizing for this ridiculously long post, but I tried to provide as much code and data as possible for you to refer to. I am working on a video project where I will need the flexibility of the AVQueuePlayer (foremost the ability to scale and layout the video layer freely, as well as creating my customized controls). Problem is, I need to be able to mix video content of different types (in this case progressive download .mp4 and http streaming .m3u8). Here's where

问题 This is answer for my search which i did for creating videos to stream on android. Though android supports mp4 for streaming but not easily. The simple steps which i deduced from my experience are:- 1) using super encoder first of all encode the videos the parameters are- A) Top parameters: a) mp4 as container b) mpeg-4 video codec c) aac-lc audio codec B) Video parameters: d) dimension as 380x480,the aspect ratio will be automatically created e) frame rate automatically sets as 29.97 or else

问题 I need HTTP/RTSP Video Streaming with Android. Any Ideas ? Is that possible to go with JMF with Android ? Any Working examples ? Already tried with http://davanum.wordpress.com/2007/12/29/android-videomusic-player-sample-from-local-disk-as-well-as-remote-urls/ Its not working with my case. Are there any specific types of videos that Android can stream ? Thanks. 回答1: You don't necessarily need JMF. Android has built in support for HTTP/RTSP video streaming . Try this: String LINK = "type_here

Optimization: Dumping JSON from a Streaming API to Mongo

由 白昼怎懂夜的黑 提交于 2019-12-04 19:43:02
问题 Background: I have a python module set up to grab JSON objects from a streaming API and store them (bulk insert of 25 at a time) in MongoDB using pymongo. For comparison, I also have a bash command to curl from the same streaming API and pipe it to mongoimport . Both these approaches store data in separate collections. Periodically, I monitor the count() of the collections to check how they fare. So far, I see the python module lagging by about 1000 JSON objects behind the curl | mongoimport

HTML5 video from MVC3 action not working correctly

由 ﹥＞﹥吖頭↗ 提交于 2019-12-04 17:54:41
I'm serving video from an MVC3 site, with the controller action that returns the video returning a FilePathResult, and when trying to play back in the browser, I'm seeing some frustrating issues, regardless of my using video.js or mediaelement.js. Chrome doesn't let you change the position using progressbar, nor does it allow you to replay the video once it has completed IE9 seems relatively fine Firefox doesn't show the elapsed/remaining time correctly However, if I just give a relative path to the file being hosted, it all works fine. The videos need to be available only to users who belong

Android Record raw bytes into WAVE file for Http Streaming

由 左心房为你撑大大i 提交于 2019-12-04 14:16:41
问题 So I am using AudioRecord from Android to record raw bytes and for writing them into a .wav file. Since Android has no support for this I had to write the .wav file headers manually with the following code: randomAccessWriter.writeBytes("RIFF"); randomAccessWriter.writeInt(0); // Final file size not known yet, write 0 randomAccessWriter.writeBytes("WAVE"); randomAccessWriter.writeBytes("fmt "); randomAccessWriter.writeInt(Integer.reverseBytes(16)); // Sub-chunk size, 16 for PCM
