[FFmpeg-user] Screen-casting - RTSP - VMIX

[Bilarus T]

Hello FFmpeg community

I'm trying over 2 months to successfully use FFmpeg to stream locally my
desktop to VMIX but without success and it is getting me insane

I'm using screen-capture-recorder to capture at 60fps in 1080p

I have searched the whole web and can't find anything near to my problem.

my current try is as follow :

>ffmpeg -re -rtbufsize 1500M -f dshow -i
video="screen-capture-recorder":audio="
virtual-audio-capturer" -r 60 -vcodec libx264 -threads 4 -tune zerolatency
-b 35
00K -f rtsp -rtsp_transport tcp rtsp://109.68.150.212:8550/


And I'm getting this error continuously :

*[dshow @ 0000000003020c60] real-time buffer [screen-capture-recorder]
[video inp**ut] too full or near too full (92% of size: 1500000000
[rtbufsize parameter])! f**rame dropped!*

Could you please tell me what I'm doing wrong? Also, is it necessary to use
FFServer ? I'm really new into this but I'm starting to like it very much,
really interesting processes and open to learn from you

Greetings, Bilarus
