RTMP to Facebook does not work when the hlsMuxingEnabled is enabled in AMS.

[amarantmeida]

Short description

RTMP endpoint to Facebook does not work when the HLS muxer is enabled in AMS. When we set "hlsMuxingEnabled" to "false" in the settings of an Application everything is fine. But as soon as we switch it to "true", there's no stream going to FB. I am able to reproduce the same on test server on AmatTest app

Environment

• Operating system and version:
• Java version:
• Ant Media Server version: 2.12
• Browser name and version:

Steps to reproduce

1. Under advanced settings of your app, make sure hlsMuxingEnabled:true, and "Save"
2. Start a stream (webrtc in my case), then add FB as RTMP endpoint. (ex- rtmps://live-api-s.facebook.com:443/rtmp/FB-28286452277612722-0-AbzwBnqCLJlUC9L-)
3. Facebook Live stream doesnt show the stream.
4. Now disable the setting, i.e; hlsMuxingEnabled:false, and "Save"
5. Then restart the stream
6. The stream will now appear on Facebook.

Expected behavior

__Stream should appear of facebook even when hlsMuxingEnabled:true, __

Actual behavior

When hlsMuxingEnabled:true, Stream doesnt pass on to Facebook

I have build ffmpeg with Mbedtls enabled , even then the connection fails to establish with facebook. by default it was using tls 1.3 , I changed ffmpeg src code to force ffmpeg to use tls 1.2 instead then some time the connection works and some time it does not work.

when forcing mbedtls to use tls 1.2
