Hi @zh000323! I'm Dosu and I’m helping the AstrBot team.

这个问题的根本原因是 ensure_wav() 函数在处理 .silk 格式语音时，虽然能通过 magic bytes 识别出 silk 格式，但没有走专门的 silk 解码路径，而是直接把 .silk 文件丢给 ffmpeg 转换 [1]。ffmpeg 不支持直接解码腾讯 SILK 格式，所以报错 Invalid data found when processing input。

代码库中其实已经有专门的 tencent_silk_to_wav() 函数使用 pysilk 库正确解码 silk 文件 [2]，各个 STT provider 也都在用这个函数。但 preprocess_stage.py 第 74 行调用的 ensure_wav() 没有对 silk 格式做特殊处理，直接走了 convert_audio_to_wav() → convert_audio_format() → ffmpeg 的通用路径 [3]。

语音功能正常工作是因为后续的 STT provider 会再次检测 silk 格式并用 pysilk 正确解码；这个 ffmpeg 报错发生在 ensure_wav 阶段，异常被 catch 后只打了 warning 日志，不影响实际功能。

修复建议： 在 ensure_wav() 中添加对 silk 格式的判断，当检测到 silk 时调用 tencent_silk_to_wav() 而不是 ffmpeg：

async def ensure_wav(audio_path: str, output_path: str | None = None) -> str:
    if not audio_path:
        return audio_path

    audio_type = _get_audio_magic_type(audio_path)
    if audio_type == "wav":
        return audio_path
    
    if audio_type == "silk":
        from astrbot.core.utils.tencent_record_helper import tencent_silk_to_wav
        if output_path is None:
            temp_dir = Path(get_astrbot_temp_path())
            temp_dir.mkdir(parents=True, exist_ok=True)
            output_path = str(temp_dir / f"media_audio_{uuid.uuid4().hex}.wav")
        return await tencent_silk_to_wav(audio_path, output_path)
    
    return await convert_audio_to_wav(audio_path, output_path)

这样可以消除日志中的 ffmpeg 报错。
