驱动音频不存在: {audio_path}

Error message

驱动音频不存在: {audio_path}

What it means

generate_video() checks that the driving audio file audio_path (the audio that the generated video/lip-sync will be driven by) exists on disk. If not, FileNotFoundError is raised with the path before any API call. None/empty values are allowed (feature disabled).

Solutions

1. Check os.path.isfile(audio_path) from the same process before calling generate_video.
2. Use absolute paths anchored to the service's base directory.
3. Fix the upstream audio rendering step to write/flush the file before generate_video is invoked.
4. Ensure the path is accessible inside the container/VM running the service.

Example fix

// before
client.generate_video(prompt=p, audio_path=clip_audio)
// after
if clip_audio and not os.path.isfile(clip_audio):
    raise FileNotFoundError(f"drive audio missing: {clip_audio}")
client.generate_video(prompt=p, audio_path=os.path.abspath(clip_audio))

if audio_path and not os.path.isfile(audio_path):
    raise FileNotFoundError(f"drive audio missing: {audio_path}")

def has_drive_audio(p: str | None) -> bool:
    return p is None or os.path.isfile(p)

try:
    client.generate_video(prompt=p, audio_path=audio)
except FileNotFoundError as e:
    logger.error("drive audio missing: %s", e)
    raise

When it happens

Trigger: generate_video() called with audio_path set to a non-empty string whose file does not exist.

Common situations: Audio pipeline wrote to a different directory; temp file cleanup raced the call; absolute path from another host baked into config; running in container without the mount; renamed or moved asset.

Understand the failure class

Background: "File not found" and ENOENT errors: why libraries can't find a file that should exist — this error's family across 50 libraries.
