ffmpeg too chatty

[genio]

FFMPEG dumps lots and lots of stuff to stderr. Adding -loglevel panic into the mix quietens that down quite a bit, but also causes node-rtsp-stream to stop functioning as it should when run as a service via systemd.

Application

Stream = require('node-rtsp-stream');
var stream1 = new Stream({
    name: 'ipcam1',
    streamUrl: 'rtsp://192.168.0.131:554/0',
    wsPort: 9991
});

systemd config file

If I'm being dumb, please don't hesitate to point that out as I'm dumb quite often. I just don't like filling up /var/log/messages with tons of

frame=   30 fps= 29 q=31.0 size=     486kB time=00:00:00.93 bitrate=4261.3kbits/s

entries.

Thanks, Chase

@genio you're right; it's pretty verbose. I was trying to get as much debug data as I could at the time so I didn't mind it.

What exactly isn't working when you systemd-ize it? Is the client socket not picking up the data? Does it work without -loglevel panic? I can't imagine log levels changing the way that the app behaves with the websockets.

The library as-is is probably not really ready to be turned into a service without some work. You can feel free to fork and/or PR and I'd be happy to take it. It could use a verbosity option, should be fairly simple to add in via https://github.com/substack/minimist

FWIW, this was a side project that I haven't really touched for a few months (as you can tell); I'm not likely to jump back onto it for a little while. If I do I'm probably going to look at WebRTC too at the recommendation of a few others.

Hi, I'm using this library to stream video from an ONVIF camera to jsmpeg. I have the similar problem that if adding -loglevel panic to ffmpeg option, it will give me below error when jsmpeg page is launched in browser:

buffer.js:784
    throw TypeError('value is out of bounds');
          ^

Hi, I've experiencing the same issue, did someone found a fix for that ?

[kyriesent]

Unfortunately I haven't seen anything that would help. :disappointed: Seems like the videoStream is trying to write a value to the Buffer that is invalid. But without knowing what that value is, I'm afraid I can't do much.

You could try to add a sanity check to the Buffer write, and discard values that are out of bounds. But unfortunately beyond that I'm not sure what will help. Sorry!

Stale issue, closing.

Firstly, I love how easy you have made it to stream an RTSP stream using node. I am getting a similar error to the other fellas - works fine when loglevel = info, but dropping it by a single log level (logLevel = error) the stream stops working without any errors stating why. The only output I get from this is within the browser:

[.WebGL-000002028C8DFBB0]RENDER WARNING: texture bound to texture unit 2 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering.

Can you suggest anything?
