video-streaming

问题 In a nutshell, I need a way to stream (or otherwise play) a movie along with 3 to 4 other 'show angles', with the user being able to change the stream they're viewing. End result should be a video player with links/buttons for the other angles, allowing the user to switch camera streams (angles) as they wish. Here's an example: You load a page with a DIY video.. and since it includes a fairly detailed assembly process, there are 4 cameras recording different angles or locations of the work

问题 I would like to test my streaming infrastructure by generating an RTMP test video with a timestamp. This could look like that screen. The image doesn't matter. I'm after the working stream generated on-the-fly and timestamp only. I intend to use the ffmpeg tool for that purpose. The command could look something like $ ffmpeg -i image.png \ -vf drawtext="fontfile=/Library/Fonts/Arial.ttf: \ timecode='00\:00\:00\:00': r=1: fontcolor=white: \ fontsize=24: box=1: boxcolor=black@0.5: \ boxborderw

This project is supposed to demonstrate the use of Audio/Video conversations through the Lync API. I am having trouble getting the video portion to function in the sample application. The problem is in this method: /// <summary> /// Called when the video state changes. /// /// Will show Incoming/Outgoing video based on the channel state. /// </summary> void

问题 I've been playing around with the camera plugin, I know there's the possibility to capture a video via the CameraController with the functions start/stopVideoRecording , the functions will take a path for a file as an input. I'd like to be able to stream this video to a server while it's being recorded, is it possible somehow with the current capabilities of the camera plugin? 回答1: Looks like it is possible as it was done at Flutter Live with one of the development demos. Check out the

问题 Is it in any way possible to process at least 1 DShow video project on multiple machines in parallel at the same time for faster rendering or just for fun? In any language? With help of any program? 回答1: The short answer is yes, but it's not a very practical solution Lets say you did manage to create a system that broke a video up across machines for distributed decoding. You first would have to be careful on how you did "break up" the video. You must always start at keyframe and ending right

问题 Ok, I give up... Something very strange is going on and, after days of messing with this, I have to ask for help. I have a PHP script that serves an MP4 file from outside of the document root. This script works great, except for one very important (to me at least) detail: it will not give me the option to cast the content. On the same server, when I access an MP4 file that IS inside the document root, I load the page and when I click the three dots in the bottom right corner of the Chrome

问题 I have an intranet site that uses a Silverlight application to take pictures with the WebCam of the computer. Testing the site on a Development environment works fine but testing the site on a QA environment wont display any image. Looking more in deep on both sites I see that the Silverlight permissions tab has define "ALLOW" to the Development URL but the QA url does not appear at all on the permissions tab. How can I add the URL of the QA site to the permissions tab on the Silverlight
