Environment Details

ubuntu 24.04.3, RTX 2080 Ti torch==2.4.0+cu124 torchaudio==2.4.0+cu124

Steps to Reproduce

Starting app...

• Running on local URL: http://127.0.0.1:7860
• To create a public link, set share=True in launch().
  torch_dtype is deprecated! Use dtype instead!
  Device set to use cuda
  Using chunk_length_s is very experimental with seq2seq models. The results will not necessarily be entirely accurate and will have caveats. More information: Adding chunking for whisper (all seq2seq actually). Very crude matching algorithm. huggingface/transformers#20104. Ignore this warning with pipeline(..., ignore_warning=True). To use Whisper for long-form transcription, use rather the model's generate method directly as the model relies on it's own chunking mechanism (cf. Whisper original paper, section 3.8. Long-form Transcription).

  RuntimeError: Could not load libtorchcodec. Likely causes:
  1. FFmpeg is not properly installed in your environment. We support
  versions 4, 5, 6, 7, and 8.
  2. The PyTorch version (2.4.0+cu124) is not compatible with

  3. Another runtime dependency; see exceptions below.
  The following exceptions were raised as we tried to load libtorchcodec:

1. FFmpeg is not properly installed in your environment. We support
   versions 4, 5, 6, 7, and 8.

Check if FFmpeg installed.
Will keep discussion with #1234
