A web conference with three participants: a marketer, a manager and a programmer. This means you can download a YouTube video completely and then stream it via ffmpeg as a file.īut imagine this use case first. The youtube-dl library is intended for downloading. configure -enable-shared -disable-logging -enable-gpl -enable-pthreads -enable-libx264 -enable-librtmp Then, we install ffmpeg using typical spells: wget 9cQT4urTlXM: Extracting video information 9cQT4urTlXM: Downloading video info webpage The result is: 9cQT4urTlXM: Downloading webpage Now, take a video from YouTube and see its metadata: youtube-dl -list-formats Modify permissions to allow execution chmod a+rx /usr/local/bin/youtube-dl The installation process on Linux is extremely simple and is described thoroughly in Readme for Linux and for Win.ġ. The server broadcasts the received stream as WebRTC in real time.įirst of all, we install youtube-dl. ffmpeg grabs the video being downloaded, envelops it to an RTMP stream and sends to the server. Specifically, ydl connects to YouTube and starts downloading the video.
We need to implement the diagram presented above.
Below is the description of how you can do this using a tandem of this library with ffmpeg. This can be achieved by enveloping the video to a Live-stream. In order to eliminate this divergence, the video should be delivered to all spectators simultaneously. Here is the task: several users need to watch a video on YouTube simultaneously, with latency as low as possible.Īpparently, if each of spectators just starts playing a video, the stated goal cannot be achieved, because one user will receive the video faster, will the other will get it slower.
