I have been streaming with vmix to YouTube for several years and all of a sudden this past Sunday we stopped streaming and continuously had this error:
real-time buffer [vMix Video YV12] [video input] too full or near too full (65% of size: 128000000 [rtbufsize parameter])! frame dropped!

I do not think this has anything to do with our upload speed as I get this error message 20 seconds after pressing the "Stream" button even when I'm not connected to YouTube. Our upload speed is greater than 300mbs for reference.

I have since changed the stream settings in vmix from 1080p to 720p and it streamed for a few minutes without issue.

I've seen this issue reported here a lot. Has there been any resolutions to this?

I just posted about a similar problem (sorry to create a duplicate, I didn't see this thread)
https://forums.vmix.com/...e-flashing-Stream-button

In my case I get the error continuously but the stream does not stop, just some frames are dropped - is your stream actually stopping? I'm only sending 720p and still getting the error.

Have you tried changing to one of the other youtube ingest servers (b.rtmp.youtube.com, x.rtmp.youtube.com)?

same issue here. im doing live streaming to youtube frequently. almost the all time.

lot of googling, im using cable, i noticed my DNS was 1.1.1.1 (cloudflare)

i manually change the DNS to 8.8.8.8, 8.8.4.4 (google DNS) . and im noticed huge improvement (or no more orange stream button anymore)

nothing to do locally, as the orang button MEAN is : Stream Starting

The stream button will be orange just after streaming has been started to indicate that a connection to the streaming provider is currently in progress.
Once a successful connection has been established, the stream button will change to red.

maybe youtube URL problem? rtmp://a.rtmp.youtube.com/live2
