Question XUI One - Constant 0x0 Resolution Error on Astra Satellite Streams (High-End Xeon Infrastructure)

[Infest84]

Hi everyone,

I'm facing a recurring issue with several satellite channels (Astra) on XUI One. The main symptom is that users report "no image," and when checking the stream status in the panel, it shows a 0 x 0 resolution, even though the bitrate is active and stable (around 5,000 Kbps).

My Hardware Specs:

• Main Server: Intel Xeon (20 Cores / 40 Threads), 64GB RAM.
• Load Balancers: Intel Xeon (16 Cores / 32 Threads), 128GB RAM.
• OS: Ubuntu (latest updates).
• XUI Versions Tested: 1.5.5, 1.5.12, and 1.5.13 (issue persists across all versions).

Problem Details:

1. These streams used to work perfectly on my previous (lower-spec) servers. Since migrating to this high-end infrastructure, this issue appeared randomly across multiple channels.
2. The panel detects the incoming traffic (KBPS), but it fails to map/identify the video codec or resolution.
3. I have tried restarting the streams and clearing the cache, but the 0x0 error eventually returns.
4. Current load is under 1,000 channels, and CPU/RAM usage is very low (well within limits).

Questions:

• Is there a specific setting in Stream Settings or at the Kernel/FFmpeg level that I should adjust for these high-thread Xeon servers?
• Could this be related to a timeout in the stream analysis or a buffer issue in the new datacenter?

Any advice or insights would be greatly appreciated. Thank you in advance!

Update: Issue Solved

I managed to fix the 0x0 resolution error. After analyzing the FFmpeg logs, I noticed several SPS unavailable and dimensions not set errors. This indicated that FFmpeg was failing to parse the stream headers (SPS/PPS) from the Astra satellite source within the default time frame.

The Solution:I increased the Analysis Duration and Probe Size in the XUI settings.

• Old Value: 500000 (500KB)
• New Value: 10000000 (10MB)

By increasing these values to 10MB, I gave FFmpeg enough "headroom" to properly read the sequence parameters before attempting to write the output header. Since my infrastructure is running on high-end Intel Xeon processors (16 & 20 Cores) with 64GB/128GB RAM, this extra processing overhead is negligible and the streams are now stable with the correct resolution.

If you are running satellite feeds on high-performance dedicated servers, I highly recommend bumping these values to at least 5M or 10M to avoid metadata drops.
