video-streaming

问题 I'm trying to load a mp4 video stream from Django to Vue.js. I followed the solution here and got a byte string via my axios API which I concatenated to data:video/mp4;base64, , and then binded it to the video tag's :src property, but the video is not displaying. Is this the correct way to stream videos from Django 3 to Vue.js? What am I doing wrong? Api.js code snippet: import axios from 'axios' export default () => { return axios.create({ baseURL: `http://127.0.0.1:8000/`, headers: {

问题 OBJECTIVE: I'm building a FPV robot, I want to control it with a with a webbrowser over a local wi-fi connection. I'm using a raspberry pi 3B+ with Raspbian Stretch. I built my own motor control and power regulator hat. After lots of research testing, I decided to use node.JS as http server and socket.io to provide a low latency bidirectional communication with my robot. This stack achieve about 7ms of latency. Picture of the robot PROBLEM: I need to stream low latency video from an USB

问题 I was wondering if it is possible to 'stream' data using the OpenCV VideoWriter class in Python? Normally for handling data in memory that would otherwise go to disk I use BytesIO (or StringIO). My attempt to use BytesIO fails though: import cv2 from io import BytesIO stream = cv2.VideoCapture(0) fourcc = cv2.VideoWriter_fourcc('x264') data = BytesIO() # added these to try to make data appear more like a string data.name = 'stream.{}'.format('av1') data.__str__ = lambda x: x.name try: video =

问题 How can I search for Miracast compatible devices (may be using WiFi Direct) in android? I just got to know that DisplayManager and Presentation class in Android 4.2 help in presentation & miracast. But is there any way I can check if the other device is Miracast compatible / search Miracast sink? Thanks Smitha 回答1: android framework source codes shows how to search miracast sink devices. basically using WiFi Direct devices search API, discoverPeers -> requestPeers -> isWifiDisplay &

问题 Is it possible to capture stream from webcamera(in front end) and stream it to server via hls or rtmp with pure js(no flash). And if there are another protocol which let send stream as stream(unlike hls), will be prefered. 回答1: I found solution. There is no (yet) any way to "convert" stream received from navigator.getUserMedia() to rtmp in front-end. But we can use MediaRecorder Api. In client Side const stream = await navigator.getUserMedia(options) const recorder = new MediaRecorder(stream)

问题 I'm researching for a week to find a simple and platform independent method to stream a mp4 file to any browser. In case of browser incompatibility progressive stream(direct download) method will be used. My scenario is like this: single mp4 file (not segmented and multiplexed(Audio+Video) ) HTTP Byte-Range serving supported progressive stream (direct file download) supported in case of browser incompatibility After studying Apple HLS, Adobe Flash Stream, Microsoft Smooth, RTSP and MPEG-DASH

问题 I'm trying to stream HLS content using node.js. And somehow it is not working. It'll be of great help if someone helps me out. Problem:- Trying to serve HLS content from node.js (not live stream, but a set of .ts files and .m3u8 playlist , or in other words VOD content ) Folder Structure stream_test |--- app.js |--- node_modules |--- streamcontent |--- test.m3u8 |--- segment0.ts |--- segment1.ts . . . |--- segment127.ts My app.js looks like this var http = require('http'), url = require('url'

问题 I'm working with ffmpeg to process an incoming MPEGTS stream from remote cameras, and deliver it to multiple clients using my app. Technically, I'm using ffmpeg to convert the incoming stream to an MJPEG output, and piping the data chunks (from the ffmpeg process stdout) to a writeable stream on the client http response. However, I'm facing a problem- not all data chunks represent a full 'whole' frame. thus, displaying them in a row in the browser, results in a flickering video, with half

问题 I want to cut a video in specific start & end time & save it. I cant understand how to cut specific time of that video by Node JS. Video copy code : return new Promise(function(resolve ,reject){ var ffmpeg = require('fluent-ffmpeg'); ffmpeg(fs.createReadStream(path.join(__dirname,'..','..','/video.mp4'))) .seekInput('01:00') .duration('02:00') .outputOptions('-strict experimental') .on('start', function(commandLine) { console.log('Spawned Ffmpeg with command: ' + commandLine); }).on('end',
