由 人盡茶涼 提交于 2019-12-03 13:55:14
问题 I am researching video streaming for an iPhone application that I may have to write in the near future. The application does a whole lot other than stream video, but video aspect is the part that I have no experience with. Anyone know of any good articles on writing streaming video apps? Google seems to inundate me with links that have everything not to do what I seek. Thanks, m 回答1: Apple provide good documentation on the media framework i ntheir docs.

Online encrypted streaming video files with AES in exoplayer android

由 让人想犯罪 __ 提交于 2019-12-03 13:40:49
问题 I have video files encrypted with AES stored on server. How to stream them online in exoplayer? I don't want to download the file and decrypt it: waiting for the download to complete and then play decrypted file. 回答1: I would suggest taking a look at the UriDataSource or the DataSource interface. You can derive from DataSource and provide an implementation very similar to UriDataSource and pass that into ExoPlayer. That class has access to the read() method which all the bytes pass through.

App removed from Google Play because of Youtube API problems

由 痴心易碎 提交于 2019-12-03 12:42:26
I have developed an application for Android that displays video from my channel on YouTube using YouTube API. I show the video directly through YouTubePlayerView class. I don't use authorization of users on YouTube, just show video in player from my channel. I also use video ad in the same Activity. I show video ad before YouTube video. But I'm not sure that this is so important. Also I have another activity that show list of videos from my channel. For list item I use title of video and thumbnail. I take title and thumbnail from YouTube site using: http://img.youtube.com/vi/" + url + "

Play video in Android from a bytes stream

由 给你一囗甜甜゛ 提交于 2019-12-03 12:41:02
Is there any way to play a video from a bytes stream in Android? I'm using an specific communications middleware so I can't just pass the http/rtsp link to the MediaPlayer object. I was wondering if I can wrap my stream with a local http/rtsp link so I can play the stream instead of waiting until the file is downloaded to play it. My middleware works over TCP so I've also thought that I can wrap my rtsp datagrams with a tcp datagram and interpret them on the client somehow, after removing the TCP headers. I'm really surprised that I can't just pass a bytes stream to the MediaPlayer. Thanks in

Play embedded video resource as stream

由 99封情书 提交于 2019-12-03 12:40:37
问题 EDIT : I changed my question to better clarify the issue. How is it possible to play a video from a byte array (taken from embedded resource) using DirectShow.Net library? Since I'm going to prevent users from accessing the video file, I need to embed the video file as resource and play it. Thanks in advance. 回答1: It's a bit non-standard, but you could use something like WCF to self-host an endpoint inside your desktop application. Then set the source of the video input to be the "URL" to

NodeJS, OpenCV and Streaming Images Using Net Socket

由 孤人 提交于 2019-12-03 10:05:25
问题 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');

DXGI Desktop Duplication: encoding frames to send them over the network

由 …衆ロ難τιáo~ 提交于 2019-12-03 09:59:08
问题 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
