Darwin - Streamed video freezes at vlc player

[hislitermos]

Hello,

Case: I have been streaming the video coming from capture card to Darwin streaming server.
When I watch the video coming from Darwin server with another VLC player, video freezes time to time. Pixelation occurs.

Stream PC
Config: 8GB Ram, Win7 Ultimate, I7 Processor
CPU Usage: 8%
RAM Usage: 25% (2GB)
Upload speed: 5Mbps
Streaming Method: RTP with SDP

Darwin streaming pc:
Config: Debian OS, 32GB Ram
Upload and download speed: symettrical - 100Mbps upload & download
Darwin Server Version: 6.0.3
Darwin Server API Version: 5.0

I also read some similar threads in this forum but none of them exactly fit my case.
I tried different variations with RTP & RTP/MPEG , different bitrates and frame rates.

Please find below some screenshots. In general video player shows good video quality but in other times stuttering.

What do you suggest me to get rid of this annoying screen?

Thanks in advance
