video-streaming

问题 First, I wish to emphasize the keyword from . There are a lot of questions and answers on this topic but I found that no answer provide a step by step road-map to achieve this. What I wish to achieve : I wish to stream the video and audio (live) being recorded from the camera of iPhone/iPad to my server. And that's it. What have I figured till now : I guess that we can't use HTTP live streaming because it's meant for server to client and not client to server. AV framework allows the output

问题 We are storing some video files as binary in NoSQl database, NoSQL database exposes Rest API to read data from database. We are able to receive the binary data (with no file extension) from RestAPI, but web browser starts to download the file instead of playing it in the browser.

问题 Is it possible to record a voice onto the uploaded video using PHP? 回答1: No you can't, at least not by just using PHP, because PHP in itself doesn't provide the necessary libraries for recording sound and editing videos. To actually record video and sound you'll need libraries like ffmpeg (there's a handy extension for PHP) for video editing and SoX for sound installed on your server. You can then access these programmes by using the the exec() function in PHP, for example. The implementation

问题 I am trying to build an application which would act as a streaming proxy server with caching features. The thing is, I want to do it manually without using NewSingleHostReverseProxy . Manually means performing these steps: Perform single GET request to the server Read resp.Body to buffer and write to connected client(s) And the issue is that VLC doesn't play anything. If I access stream directly - VLC plays it without problems, but if I do it via GO - VLC (as well as Kodi) just keeps

问题 I'm trying to include some videos on a website I help to maintain using JW Player, and some internet explorer users are reporting that they don't see the video box show up at all (i.e. the space where the video player should be is completely blank, not displaying an error about flash version or anything like that). Here is the code that I'm using to initialize the video player: <div id='player_5465'></div> <script type="text/javascript"> jwplayer("player_5465").setup({ file: "http://bmt.umn

问题 I am using dshownet(first time) and C#. I have got a sample to take the web cam input and display it on a form. I now need to draw a rectangle on top of the video stream using the mouse. (the intent is to track what is inside the box from there onwards). I heard that there is something called VMR. So I went to the dshownet samples and went through them. I didnt find any samples that use the mouse to overlay a shape on the video stream. Someone on here suggested to use colorkey. Another person

问题 I've got a cheap Chinese IP webcam that has a web interface showing live video. The video appears to be a sequence of jpeg images fed into the browser. If I point wget at the URL http://my-ip-camera/video.cgi I receive a big chunk of streamed data in the following format: --ipcamera Content-Type: image/jpeg Content-Length: 46056 JFIF header data ... lots of data ... this pattern repeats for every "frame". Is this some "standard" streaming format I can play/transcode with something, or is it
