Common encoder errors and fixes

Most encoder problems fit one of four patterns:

Symptom	First check
No inbound preview	Channel URL, key and encoder output state
Video but no audio	Correct audio device, track selection and codec
Frequent disconnects	Upload stability, Wi-Fi and bitrate headroom
Picture is delayed or stutters	Keyframe interval, CPU load and destination requirements

Copy the channel credentials again rather than typing them. Confirm the encoder is publishing the expected resolution and frame rate, then test at a lower bitrate. If the inbound preview is stable, do not change the encoder for a single failing destination — inspect that destination's log and platform requirements.

Never send a screenshot containing a stream key. Rotate the key from the channel controls if it has been exposed.
