video-streaming

I'm trying to write an app which will capture a video stream of the screen and send it to a remote client. I've found out that the best way to capture a screen on Windows is to use DXGI Desktop Duplication API (available since Windows 8). Microsoft provides a neat sample which streams duplicated frames to screen. Now, I've been wondering what is the easiest, but still relatively fast way to encode those frames and send them over the network. The frames come from AcquireNextFrame with a surface that contains the desktop bitmap and metadata which contains dirty and move regions that were updated

My end goal is to stream video from my laptop to a server. I'm trying to accomplish this by using NodeJs on the laptop & the server. I use the OpenCV library to capture the video on the laptop and save it to a jpg file. I then read the file and convert it to base64 so that I can transport it using the Net.socket module in Node. This is a continous process: capture, encode, and send. Here is the server code for just transmitting one jpg file: var cv = require('opencv'); var fs = require('fs'); var net = require('net'); var camera = new cv.VideoCapture(0); var server = net.createServer(); server

Does the HTML5 video element support non-HTTP-based (HLS, SmoothStreaming, etc.) live-streaming protocols? Does it support RTP/RTSP streaming protocols? Does it support RT M P? Are there specific browsers that support or don't support it? Jaruba HTML5 tag has very limited support on video sources. The video sources supported are also limited to what browser your visitors use. Please see: http://www.w3schools.com/html/html5_video.asp for a table of supported formats depending on browser. To sum it up, HTML5 Video supports MP4 on all browsers and OGG, WEBM in FireFox, Opera and Chrome. With that

We have a customized Flash/HTML5 video player we use for users on our site. I'm currently fleshing out the experience for users who have 'suboptimal' bandwidth--basically we'd like the client side code to be able to detect poor user experience due to excessive buffering. I would like to test this "poor bandwidth" handling code in my local development environment. Does anyone know of good techniques for simulating "poor bandwidth" in a local environment for testing purposes? More specifically I have my local browser connecting to a virtual machine with instances of uWSGI, nginx, and python

Need to decode h264 stream and get the pixel buffers I know its possible with video tool box on iOS 8 1.How do I convert the h264 stream to CMSampleBufferRef ? 2.How do I use the video tool box to decode? I assume you get the stream in Annex B format, if it is already in AVCC format (read MP4), then you can you the AssetReader and do not need to do much. For an Annex B stream (this is what ppl. often call raw h264 stream). extract SPS/PPS NAL units and create a parameter set from then. You receive them periodically. They contain information for the decode how a frame is supposed to be decoded.
