FFmpeg Streaming - Next Step: RTMP Configuration and Usage

[@samuelhalder8472]

Wow, can we also steam live camera and stream it on local network? Just like how NDI works.
We have 4 cameras in a hall which goes to atem and goes to pc, if we can take the input and stream it on network so that we can send it on another hall which is 200 meter away. We will use fiber cable.

[@devstefit]

Yes you could. You can follow the instructions in this video, feeding the input as the camera, respecting the inteface your cameras are connected on the server PC. Some complication may derive on how do you want to get the camera streams: separate or together in a video.
If separate: you have to create different connections, as different references.
If together in a video: you can use a complex filter, more reference here ruclips.net/video/Yc16I6i9xDU/видео.html

Can you make a video guide on to make HTML overlays. Is it possible with filters ? Pipes. Maybe like a virtual screen capture.

Bravissimo Stefano, l'accento italiano si sente tanto ma devo dire che sei uno dei + bravi Italiani che ho sentito in merito ad "Accento" (te lo dico da italiano all estero eh ... :)). 'Scolta ho una domanda ... ma per entrare un po + sul tecnico dove mi consigli di guardare? Intendo sulle varie opzioni di ffmpeg, mux / demux / encoding etc etc. Online non trovo tanto materiale in merito (tanta teoria, ma parzialemtne declinabile poi sui vari softwares). Ciao grande, bravo, Luca.

[@devstefit]

Buongiorno Luca, grazie mille per il feedback! Ebbene sì, bisogna lavorare ancora un po' sull'inglese per essere un po' più neutro. Mi fa piacere che il video sia piaciuto.
Per andare più nel dettaglio su queste cose ci sono le guide di FFmpeg ma anche un paio di testi. Uno che posso consigliare è FFmpeg - From Zero to Hero by Nick Ferrando.
Più informazioni sul sito relativo ffmpegfromzerotohero.com/
In futuro ho in programma di trattare qualcosa di più profondo e tecnico comunque, tempo permettendo. Stay tuned!

i setup in ubuntu, but when in run ffmpeg command with streaming to youtube via rtmp, then i check pid using of ubuntu. it show alot of pids are using. not like in mac, it only use one pid. can you explain for it ?

[@devstefit]

It may depend on the way it is compiled. I did not go so deep in the implementation. Is the Linux implementation eating more resources than the Mac one?

[@CONGOMONPAYSTV]

From 8 minutes, where did you get terminal to config and update ubuntu and nginx ????
That tetminal is command ? Cmd from laptop ?

[@devstefit]

I ran the Ubuntu Linux on a virtual machine, to show both on the same screen. I usually work like this on my videos 😅 Sorry for the confusion!

[@knowledgeseeker83]

Can you please explain this process using srt protocol?

[@devstefit]

It is on the list of future videos. Will be out sooner or later

[@undergroundnews_dk]

SRT is great and fast like UDP ;)

[@syncsolutions-softwares]

Hello,
Can we access the stream outside the network?

[@devstefit]

Yes you can! If you set the firewalls properly and the server is accessible from outside, you should access to the service from outside without any problems. Actually, this is how it is intended to be used.

Your notes file is missing the -f flv

[@devstefit]

Thanks for pointing it out! Corrected already

thank😍

[@devstefit]

Thanks for watching!

big buck bunny - the most converted video file 😂

[@devstefit]

True story! 🤣

is there another solution to this? nginx installs and runs, but i can't stream to it. OBS says the stream url is invalid. tried nmap on my server and the rtmp is open and alive

[@devstefit]

The system is meant to transmit streams from the server to the client. You set everything correctly, maybe you are using it on the other way around.

[@lands1459]

@@devstefit not sure what you mean but i got it to work. i stream to the rtmp server with obs and i can watch the stream on as many clients as i'd like

[@devstefit]

@@lands1459 Sorry, I misunderstood your question. I understood you wanted to use the server to receive streams. I am glad you solved! And thanks for your feedback!

[@patrickpanhuysen9618]

I am getting this message after adding rtmp text with nano, unknown directive "rtmp" in /etc/nginx/nginx.conf. File test failed. Got a solution ?

[@devstefit]

Sorry to hear that... Which operating system are you using? This is valid for Ubuntu 22.04 and derivatives: if you are using another Linux version there might be the need load its RTMP module manually. More info available here:

I hope it helps!

[@patrickpanhuysen9618]

@@devstefit Thanks for the advice, looks like i'm not the only one with this problem. Think it's a symlink issue between nginx and the rtmp module.

[@devstefit]

Thanks for notifying! I hope the troubleshooting might be useful for somebody
