Stream Udp

Hello everyone!!

I’m streaming video via UDP, but I’m facing issues.
For testing, I open the Caspar Client, select the correct channel, and play the video.
On the destination machine, I’m trying to open it in VLC using the command udp://@:5001.
The video doesn’t show up, and the audio is choppy.
This is my configuration in Caspar’s config file.

1080i5994 udp://:5001 -codec:v h264_nvenc -preset:v fast -b:v 6000k -filter:v format=pix_fmts=yuv420p,fps=30 -format mpegts false false

This is my Caspar Server setup, version 2.4:
Core i7 8th Gen, 18GB RAM, Nvidia GForce RTX 3060

Am I doing something wrong, or is there something missing in my configuration?
Can anyone help me with this issue?

Any help would be greatly appreciated.
Thank you all!!!

This is my Caspar.config,

<channel>
	<video-mode>1080i5994</video-mode>
	<consumers>
		<ffmpeg>
			<path>udp://<MyIP>:5001</path>
			<args>-codec:v h264_nvenc -preset:v fast -b:v 6000k -filter:v format=pix_fmts=yuv420p,fps=30 -format mpegts</args>
			<separate-key>false</separate-key>
			<mono-streams>false</mono-streams>
		</ffmpeg>
	</consumers>
</channel>

Has anyone ever had this problem?"

Have a look at this thread. One of the items that has frequently been mentioned in solutions to UDP streaming is the importance in setting the ethernet packet size (the ?pkt_size=1316 part of the command.
