I am new to torchaudio, and I am trying to use StreamReader to get data from my microphone, but I cannot get it to start because it can’t access FFmpeg. ```auto from torchaudio.io import StreamReader streamer = StreamReader( src='audio=@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\wave_{A531F508-ED15-42F3-A46F-9C8ADB26C05A}', format='dshow', ) for i in range(streamer.num_src_streams): print(streamer.get_src_stream_info(i)) ``` ```auto ImportError Traceback (most recent call last) Cell In[2], line 4 1 import matplotlib.pyplot as plt 2 from torchaudio.io import StreamReader ----> 4 streamer = StreamReader( 5 src='audio=@device_cm_{33D9A762-90C8-11D0-BD43-00A0C911CE86}\wave_{A531F508-ED15-42F3-A46F-9C8ADB26C05A}', 6 format='dshow', 7 ) File d:\Python\torchaudio\.venv\Lib\site-packages\torio\io\_streaming_media_decoder.py:526, in StreamingMediaDecoder. __init__ (self, src, format, option, buffer_size) 524 self._be = ffmpeg_ext.StreamingMediaDecoderFileObj(src, format, option, buffer_size) 525 else: --> 526 self._be = ffmpeg_ext.StreamingMediaDecoder(os.path.normpath(src), format, option) 528 i = self._be.find_best_audio_stream() 529 self._default_audio_stream = None if i < 0 else i File d:\Python\torchaudio\.venv\Lib\site-packages\torio\_extension\utils.py:25, in _LazyImporter. __getattr__ (self, item) 24 def __getattr__ (self, item): ---> 25 self._import_once() 26 return getattr(self.module, item) File d:\Python\torchaudio\.venv\Lib\site-packages\torio\_extension\utils.py:39, in _LazyImporter._import_once(self) 37 def _import_once(self): 38 if self.module is None: ---> 39 self.module = self.import_func() 40 # Note: 41 # By attaching the module attributes to self, 42 # module attributes are directly accessible. 43 # This allows to avoid calling __getattr__ for every attribute access. 44 self. __dict__.update(self.module. __dict__ ) File d:\Python\torchaudio\.venv\Lib\site-packages\torio\_extension\utils.py:143, in _init_ffmpeg() 141 def _init_ffmpeg(): 142 ffmpeg_vers = _get_ffmpeg_versions() --> 143 ext = _find_ffmpeg_extension(ffmpeg_vers) 144 ext.init() 145 if ext.get_log_level() > 8: File d:\Python\torchaudio\.venv\Lib\site-packages\torio\_extension\utils.py:122, in _find_ffmpeg_extension(ffmpeg_vers) 120 _LG.debug("Failed to load FFmpeg%s extension.", ffmpeg_ver, exc_info=True) 121 continue --> 122 raise ImportError( 123 f"Failed to intialize FFmpeg extension.

I am on windows and the version I have installed for FFmpeg is 6.1.1. ![ffmpeg](https://discuss.pytorch.org/uploads/default/original/3X/5/c/5c6248c2905b59e297694ca713c09a9c7010b06d.png) I have tried to look this up but I cannot find anyone with a similar issue. I am on windows 10 too, any help would be appreciated. Thank you. ---

[Installing pre-built binaries — Torchaudio 2.3.0 documentation (pytorch.org)](https://pytorch.org/audio/2.3.0/installation.html) > When searching for FFmpeg installation, TorchAudio looks for library files which have names with version numbers. That is, `libavutil.so.` for Linux, `libavutil..dylib` for macOS, and `avutil-.dll` for Windows. ---

You can install shared FFmpeg e.g. using winget: `winget install --id=Gyan.FFmpeg.Shared -v "6.1.1" -e`, ensure ffmpeg is on PATH with the correct version. Then torchaudio should find the necessary files.
