You could use libopus or libopusfile C libraries to dynamically decode Opus files to raw PCM audio and feed that to a memory buffer that AVAudioPlayer could decode.您可以使用libopus或libopusfile C 库将 Opus 文件动态解码为原始 PCM 音频，并将其提供给 AVAudioPlayer 可以解码的内存缓冲区。 You would most likely need to prepend the memory buffer with AIFF/WAV/RIFF header bytes that describe the PCM data.您很可能需要在内存缓冲区中添加描述 PCM 数据的 AIFF/WAV/RIFF 标头字节。
