For those of you interested in re-streaming your ip cams or other videos sources as HLS and playable in the browser or app, I have some nodes that are available to test. npm install kevinGodell/node-red-contrib-mp4frag npm install kevinGodell/node-red-contrib-ui-mp4frag node-red-contrib-mp4frag is…

Hi, I don't know if this can help (I haven't read all the messages from the beginning but I'll do it as soon as I can). With sub-flow you can set some "environment properties" that can be changed via messages too. And these can be even used to modify some settings of the inside nodes. I used this fe…

Still waiting for someone to pass by. But the quality is not so good. See the video below. Since the sequence of durations are just 1 second I believe the lag is very low. When I tried with the CPU solution (libx264) I had good quality bud very long lag. If I only could improve the quality of the mp…

A car finally passed by, I would say the lag is around a few seconds. Too early to say if it is yet useful with the quality, stability, lag, why it stops in browser etc. Maybe the RPi3 is not powerful enough. I think I need to wait for Kevin's @kevinGodell judgement EDIT: trying again to verify wit…

[image] krambriw: EDIT: trying again to verify with libx264 (using CPU instead of GPU) does give very good picture quality, browser doesn't stop but sequence durations around 18 seconds that gives the lag :thinking: we are not far from the goal, sacrifice a little quality but with the lowest …

[image] krambriw: Edit /boot/config.txt and change to at least gpu_mem=128 That reminds me. I had to change that when I was trying to get h264 gpu decoding to work on the pi 4. I forgot what the error was, but it definitely was not allocated enough gpu memory by default. The maximum (that all…

Dear Kevin, to start, this is what I have, see below Also just would like to mention that the streaming in the browser is very "sensitive", wrong word maybe, to stop if focus is lost. I mean if the browser gets minimized or if you click anywhere else on the desktop so that the browser is not in the…

[image] kevinGodell: currently focused on the socket.io stuff No problem at all, I understand, no rush I tried it with Chrome and Safari on mac, with Chrome and Edge on Windows and I would say the behavior is the same for all on both mac and Windows If I have the browser open and prepared, …

[image] krambriw: Video playback error If you see that, there should also be a console.error message in the browser stating the issue, I hope.

Yes, this is what I see in the console when this happen Best regards, Walter [image]

[image] kevinGodell: So, a segment duration of 10 seconds will mean that the real-time video playback will be delayed by that much time plus the time to transfer the video from server to client and start playing it. According to my readings on one of my camera, I see sequences of 1 to 2 secon…

I understood what you meant, but thanks for clarifying. Can I ask what browser that is doing that? It is probably considered to be a feature. I can eventually detect that but am currently focused on the socket.io stuff right now. We will definitely handle those playback issues by listening to various browser states, etc.
