Original GitHub issue: https://github.com/zakk4223/CocoaSplit/issues/16

As far as I can tell I have Syphon/CamTwist setup properly - CocoaSplit sees the preview, and I added twitch as an endpoint with the stream key set to my "live_23267441_blahblahblah" key. However, whenever I try to stream I see something like:

I've used the default encoding settings for both "AppleVTCompressor" and x264. Am I missing something?

I've got this too, not sure if it's just user error though :)

2013 rMBP, 10.9

This sometimes happens if there's an issue connecting to the rtmp server. Something else could be going on though. When this happens open Console.app and filter on 'CocoaSplit'. There should be something logged, copy+paste it here and i'll see what I can figure out.

It looks like it's related to audio capture (or lack thereof). I get logs like:

2/2/2014 11:57:57.521 AM CocoaSplit[70288]: SETTING UP RESOLUTION
2/2/2014 11:57:57.539 AM CocoaSplit[70288]: Attaching destinations
2/2/2014 11:57:59.403 AM CocoaSplit[70288]: NO AUDIO EXTRA
2/2/2014 11:57:59.435 AM CocoaSplit[70288]: NO AUDIO EXTRA
2/2/2014 11:57:59.466 AM CocoaSplit[70288]: NO AUDIO EXTRA
2/2/2014 11:57:59.501 AM CocoaSplit[70288]: NO AUDIO EXTRA
2/2/2014 11:57:59.534 AM CocoaSplit[70288]: NO AUDIO EXTRA
2/2/2014 11:57:59.568 AM CocoaSplit[70288]: NO AUDIO EXTRA

Where the NO AUDIO EXTRA logs are repeated as long as the non-broadcast stays on.

The stream almost works if I select an audio source, but the stream begins to lag more and more as time goes on (i.e. Pending Out keeps going up, Dropped stays at 0). The amount to which it lags seems tied to the audio source / bitrate I pick (128kbs being the least laggy).

In any case, thanks for making this!

(apologies I just realized this was unanswered)

The NO AUDIO EXTRA thing was indeed the cause, and it's because there was no audio source selected. I think I don't allow that in newer versions but I'm not sure.

As far as the pending frames/lag that's generally a sign you can't push data out to the output destination fast enough? Too high bitrate maybe?
