RTMP is outputting video, but no audio to stream
We're back in person for our next show, but we are continuing to live stream for accessibility purposes, so it' my first time playing around with the RTMP actor. Using RTMP into Vimeo. As the title states, we're getting video into Vimeo, but no audio. Doesn't matter which audio source I choose (I'm not trying to stream system audio, just mics), I'm not getting it to stream. I can see I'm getting audio in; I can see the levels on various devices in the Live Capture Settings. Does Vimeo's livestream differ significantly from the Izzy tutorials on FB, YouTube, etc? I feel like I'm missing something very basic...
As an update, I bypassed the RTMP user actor, and used Syphon to push vid to OBS, and used OBS's mic input and then rtmp stream to Vimeo; both audio and video functioned perfectly. So there's definitely something wonky within the RTMP actor, or how it's communicating with Vimeo.
Maybe the answer lies in the "audio rate kbps" input, but also we never tested the RTMP actor with Vimeo, so I have no idea how or if it would work there.
@woland I had thought of that, so I tried with every option in the audio rate parameter; no dice. Vimeo's compression guidelines suggest 320 for the data rate and a sample rate of 48khz. "For any audio uploaded with a sampling rate over 48kHz, we will resample your audio to 48 kHz or below." It also suggests using the AAC-LC codec.
I did test out the rtmp actor on Facebook live, and it functions as it should. So it's definitely not something with my setup, it looks like it's strictly a problem with the RTMP actor not working with Vimeo specifically...
