encode.iobase.ir | Processing Failure

Processing Exception

FFmpeg could not process your supplied stream data for the next GPU server destination.

The incoming request reached the secure API edge on encode.iobase.ir, but the media payload failed validation during the decode and relay phase. The request could not be normalized into a valid stream descriptor, so processing stopped before the relay pipeline attached the destination GPU session.

Ingress Status

The endpoint returned a structured processing exception after stream validation failed during decode negotiation and relay preparation.

Diagnostic Summary

Live Failure Context

Primary Failure Reason: Invalid or incomplete multimedia payload detected during FFmpeg probe and stream map initialization.
Ingress Endpoint: https://encode.iobase.ir/v1/ingest/stream
Transport Protocol: HTTPS over TCP/443 with internal media handoff to relay worker relay-a3-edge-02.
Upstream Target: gpu://gpu-node-ir1-irancell.internal:7443/transcode/session/48119
Decoder Context: FFmpeg 6.1.2 � libavcodec 60.x � hwaccel negotiation: CUDA/NVDEC requested, fallback unavailable.
Input Container Guess: MPEG-TS candidate detected with malformed PAT/PMT timing and missing keyframe bootstrap.
Observed Client Agent: Mozilla/5.0 compatible client with incomplete or non-conforming ingestion payload.
Failure Timestamp: 2026-04-08T14:21:36.882Z
Correlation ID: corr-443-a9e2b6ff-f0c1-4b18-9bdc-2c8f8a640d44
Suggested Action: Verify client payload format, stream headers, authentication token, codec profile, and relay destination health before retry.

Header validation anomaly HTTP transport succeeded, but the media parser received a payload that did not match the expected ingest envelope for this endpoint.

Decode bootstrap failure The first analyzable packets did not contain stable frame boundaries, preventing stream map construction and downstream GPU reservation attachment.

Relay protection triggered Automatic forwarding to the next GPU server was stopped to avoid wasting compute time on a stream with corrupt initialization metadata.
