Sonilo audio exceeds the 30 MB limit

Error message

Sonilo audio exceeds the 30 MB limit

What it means

Raised when cumulative decoded audio bytes exceed MAX_GENERATED_AUDIO_BYTES (30 MB). This client-side safety cap enforces that a single video-to-music result stays consistent with the documented maximum input duration (videos are capped at 360 seconds), so an over-30MB stream means either a runaway generation or a protocol anomaly.

Solutions

  1. Confirm the source video duration is within MAX_VIDEO_DURATION_SECONDS (360); a misreported container duration can make the server render extra audio.
  2. Check logs for whether byte totals grow steadily or spike; repeated or duplicate chunks indicate a provider bug worth reporting.
  3. If legitimate outputs genuinely exceed 30 MB, raise MAX_GENERATED_AUDIO_BYTES after verifying downstream consumers accept the size.
  4. Retry the task; a one-off runaway stream is transient.

Example fix

# before
MAX_GENERATED_AUDIO_BYTES = 30 * 1024 * 1024
# after (only if longer outputs are legitimate)
MAX_GENERATED_AUDIO_BYTES = 50 * 1024 * 1024
Defensive patterns

Strategy: validation

Validate before calling

import sonilo

# expected_worst_case: duration_s * provider_max_bitrate_bps / 8
if expected_worst_case_bytes(source_duration) > sonilo.MAX_GENERATED_AUDIO_BYTES:
    raise ValueError("expected audio exceeds the client 30 MB cap")

Try / catch

try:
    audio = request_bgm(video, out, prompt)
except SoniloError as exc:
    if "exceeds the 30 MB limit" in str(exc):
        # guard against runaway streams; never resume partial files
        cleanup_temp_and_retry_once()
    raise

Prevention

When it happens

Trigger: Generation runs far longer than the source video (server ignores duration limits); repeated chunks for stream_index 0 due to a server retry loop; a client-side loop bug accumulating a chunk twice; provider changing chunk semantics so the same audio is resent.

Common situations: Long (near six-minute) sources with high-bitrate output; a provider incident causing infinite chunk repeats; mismatch between the 360-second input cap and server-side render length.
