How to stream to a custom ffmpeg instance ?

Heya !

I use to stream with OBS to a ffmpeg instance running on a private server. Unfortunately, OBS can only output rtmp streams.

I'd like to output a rtp stream thanks to Tachyon to this server, but whatever the settings, I get an "unspecified error" when I try to start the stream.

Could you point me how can I use Tachyon to send a rtp stream to a custom server ? In addition, could you tell me how the stream present itself (codecs, muxers, audio/video ports, etc) ?

I already manage to do such stream through rtp from a local ffmpeg to a janus gateway server, but using Tachyon coud leverage the power/user-friendlyness of OBS instead of a raw ffmpeg command line.

Thank you very much,
Vag'
