Now all you need to do is open up a web browser on another computer on that network and connect to (If you changed hostname, or having trouble connecting, run hostname -I to see itвЂ™s IP address and use instead.) You should see a simple webpage that says вЂњWelcome to nginx!вЂќ FFmpeg

So lets install it! sudo apt install nginx -y I personally use nginx for the final setup, as itвЂ™s fast, easy to use, and has defaults we can use out of the box. That means if we make those files accessible remotely, we can use standard HTTP to transport the video. For example, MPEG-DASH will create a manifest.mpd file that contains links to *.m4s files in the same directory which are the chunked up video files. Now we are using HLS and MPEG-DASH, which produce manifest and accompany stream files on the local system. Last time we use RTSP which required a special service of itвЂ™s own. Otherwise, skip ahead to вЂњGather Camera DetailsвЂќ.

To better understand why we need them and how to test them to make sure they are working properly, read on. Super short version: sudo apt install nginx ffmpeg -y And you donвЂ™t have to hand compile either! The two programs you will need are a file server ( nginx, apache, python -m rver, etcвЂ¦) to host the DASH/HLS content and ffmpeg. But I personally use RSTP for my own home setup still. As I already went over how to set that up, I wonвЂ™t repeat it here and only go over DASH. Using my Raspberry Pis DASH/HLS seem to have a 10~20 second delay, compared to about 1 second for RTSP. The real advantage with RTSP is the fact it really is nearly вЂњreal timeвЂќ compared to DASH/HLS.

Whereas RTSP requires additional software, such as VLC or a security system to view it. This makes it super easy to set up an all-in-one device that can host itвЂ™s own webpage to view a video at. So now the difference really comes down to how DASH/HLS are HTTP based protocols that can easily be supported in browser.

Meaning if you are trying to share these video streams with the public or view on an Apple device, you will get the most compatibility with HLS. So if DASH and RTSP can handle everything, why even bother with HLS? Long story short, Apple, who developed HLS, is a bully, so they donвЂ™t support the open MPEG-DASH on their devices. The big gotcha is what type of videos the viewer supports (and in RTSPвЂ™s case the middleman server as well.) DASH and RTSP are fully codec agnostic, meaning they are capable of wrapping around any type of video codec. So to clear this up first of all, these are вЂњcontainersвЂќ that wrap around the actual video, which is a particular вЂњcodecвЂќ (such as h264). This article will walk you through how to either copy or convert video from your webcam or pi camera, set it up as a systemd service, and finally view it on a webpage or access it remotely. This is an improvement on my previous article, Raspberry Pi Hardware Accelerated RTSP Camera, now with the option of using more modern technology, MPEG-DASH and HLS!ДЇirst off, if you donвЂ™t care about the technicalities and just want a script to do everything for you, here you go!
