Sonilo video proxy generation timed out

Error message

Sonilo video proxy generation timed out

What it means

Raised when the FFmpeg subprocess that builds the downscale/re-encode proxy of the source video exceeds the hard-coded 600-second timeout in subprocess.run, producing a subprocess.TimeoutExpired that is wrapped as SoniloError. The partial proxy file is deleted before the raise. This is a local resource problem, not a Sonilo API failure.

Solutions

  1. Check CPU utilization during proxy generation; if the box is saturated, reduce concurrent tasks or move to a beefier machine.
  2. Pre-transcode or downscale very large sources before submitting the task, or lower the source resolution and bitrate.
  3. Verify the source file plays cleanly with ffprobe/ffmpeg; a corrupt input can make FFmpeg spin.
  4. If encodes are legitimately long on this hardware, raise the timeout=600 argument in app/services/sonilo.py:180 to a value that fits your worst case.

Example fix

# before
result = subprocess.run(command, capture_output=True, text=True, timeout=600, check=False)
# after (only if hardware legitimately needs longer)
result = subprocess.run(command, capture_output=True, text=True, timeout=900, check=False)
Defensive patterns

Strategy: validation

Validate before calling

import subprocess

def probe_duration_seconds(video_path: str) -> float:
    out = subprocess.run(
        ["ffprobe", "-v", "error", "-show_entries", "format=duration",
         "-of", "default=nw=1:nk=1", video_path],
        capture_output=True, text=True, check=True,
    )
    return float(out.stdout.strip())

# reject inputs that cannot possibly finish inside the encode window
if probe_duration_seconds(video) > sonilo.MAX_VIDEO_DURATION_SECONDS:
    raise ValueError("video too long for Sonilo proxy generation")

Try / catch

try:
    proxy = generate_video_proxy(video)
except SoniloError as exc:
    if "timed out" in str(exc):
        # local CPU-bound failure: retrying on the same loaded box rarely helps
        mark_task_for_retry_after_cooldown()
    raise

Prevention

When it happens

Trigger: Uploading a long (near the 360-second limit) high-bitrate video where the proxy encode cannot finish in 600 seconds; running on a starved CPU (shared CI runner, low-core VPS) so even moderate encodes stall; FFmpeg deadlocked on a corrupted or pathological input file.

Common situations: 4K/60fps source clips on a 1-2 vCPU server; other heavy jobs competing for CPU during task runs; an input video with unusual codecs (for example 10-bit HEVC) that decodes very slowly without hardware acceleration.
