I have two Debian servers. On server A, I am producing a video multicast stream, and on server B, I record this stream. The problem is that when I watch the records I see freezing/pixelization, but If I capture the stream directly from server A there are no problems.

I'm recording on the NVME disk (checked the read/write speed and it's okay) also there are no network issues(errors or drops). I tried to record it on a ram disk and it's better but still, some freezing is seen.

Does anyone have any idea if there is some server configuration or how I could fix that? Are there any system hard drive settings I missed? Maybe socket/buffer settings?

    Without more details (like what exactly is "okay") this question will not be answered properly. Please include details, like hardware, software, bandwidth and CPU settings. In *most* cases freezing streams *are* due to network drops (which you wouldn't regognize in a dump because UDP). Even if the network runs on wirespeed, the ingestin server may not. – bjoster Aug 23 '23 at 13:31
