Having trouble getting RTMP streaming to work

[evilalmus]

image I'm using: ghcr.io/m1k1o/neko/nvidia-google-chrome:latest I'm running in unraid behind a traefik reverse proxy. The browser does come up and I am able to log in and use it just fine. When I try to start an RTMP stream I get an error and this in the log:

2023-04-02 15:17:32,526 DEBG 'neko' stdout output:

Any help would be appreciated, or if more info is needed, let me know.

It looks like there are missing some libraries when building or running gstreamer. I wonder what's needed for rtmpsink and voaacenc. Just adding them to build stage of gstreamer or runtime should fix this.

[m1k1o]

Looks like these two libvo-aacenc0 and librtmp1 are missing in runtime. Previously insalled using gstreamer1.0-plugins-bad but since we custom built gstreamer it was not included. Maybe we can get only dependencies without having installed their gstreamer?

@evilalmus this fixes the issue:

Thank you @m1k1o I'll try to figure out how to make those changes unless you have an idea when this could maybe be pulled for the ghcr.io image?

[m1k1o]

@evilalmus i updated the file, currently CI is building. Will be soon available on the ghcr.io.

Getting closer. Thank you for getting this fix in so quickly. I am no longer getting that error. Now that I am past that I am seeing two new issues.

1. If the stream key includes any special characters (in my case !) I get this error:

2023-04-03 15:35:34,436 DEBG 'neko' stdout output:
0:05:37.063166498    19 0x14ddd4002b60 ERROR                   rtmp :0:: RTMP URL: No :// in URL!

This is not a big deal, I can just change my stream key.

2. Once I change my stream key to not have any special characters, instead of the above I get this error:

   2023-04-03 15:36:48,798 DEBG 'neko' stdout output:
   0:06:51.412981893    19 0x14ddc4004300 ERROR                   rtmp :0:: RTMP_ReadPacket, failed to read RTMP packet header

   I know the target is working as I can stream to it from OBS on this same network, If there is something else I am missing or doing wrong, I am unable to figure out what it is.
