Configure OBS

This page covers the minimum configuration to connect OBS to the broadcast server.

Goal: produce a stable, audible and synchronized stream without inventing non-approved technical values.

1. Open stream settings

In OBS:

1. Open Settings
2. Open the Stream tab
3. Choose Service: Custom... (or equivalent for your OBS version)

2. Enter broadcast credentials

The format depends on your account’s mode (see Prerequisites) — both are retrieved from the panel’s “Streamers” page, see Getting Your Connection Link.

In RTMP

The information is split into two separately copyable parts in the panel:

• Server: paste the “Serveur” value shown in the panel.
• Stream Key: paste the “Cle de flux” value shown in the panel.

In SRT

You get a single full URL (no Server/Key split) — paste it as-is into your software’s SRT connection field (the exact field depends on your OBS version or SRT plugin).

Input best practices

• Copy/paste from the panel, never a hand-written value.
• Avoid hidden spaces or line breaks.
• The link is only valid during an active session: if you lose it, go back to the panel rather than reusing an old one.
• Re-validate after any secrets regeneration by an administrator.

3. Output settings baseline

• Encoder: hardware encoder if available (NVENC/AMF/QuickSync), otherwise x264
• Video bitrate: technical team approved value
• Audio: AAC at team approved bitrate
• Keyframe interval: 2 seconds

Why these settings matter

• Encoder choice affects system load and quality consistency.
• Bitrate too high causes network instability; too low causes artifacts.
• Audio quality heavily impacts perceived broadcast quality.
• Keyframe interval impacts compatibility and recovery after packet loss.

Checks to run

1. Observe CPU/GPU usage during a test.
2. Confirm there are no encoder overload warnings.
3. Confirm scene readability in a monitoring player.

4. Video settings baseline

• Base canvas: aligned with your scene composition
• Output resolution: team-approved target for your setup
• FPS: 30 by default, 60 only if validated by your team

Stability strategy

• Prioritize stability over maximum performance.
• If drops appear, reduce FPS or output resolution first.
• Change one setting at a time to isolate impact.

5. Pre-live validation

1. Start a private/off-air test
2. Check bitrate stability
3. Check audio/video sync
4. Check audio return quality

6. Recommended verification methods

1. Short test (60-120s): validates connection and credentials.
2. Longer test (10-15 min): reveals heat/load/intermittent issues.
3. Local recording review (if enabled): validates perceived quality.
4. Cross-check: second person confirms reception quality.

7. Common mistakes to avoid

• Changing multiple settings right before live.
• Forgetting to save a known-good OBS profile.
• Going live without checking microphone levels.
• Using credentials from another streamer account.

8. When to escalate to support

Escalate if:

• Connection failures persist after URL/key verification.
• Network drops are repeatable across tests.
• Encoder overload remains even after lowering complexity.

Provide:

1. Test timestamp
2. Screenshots of stream/output/audio/video settings
3. Exported OBS log
4. Short symptom description
