What version of ffmpeg does this use? Last I tried torch tools used really outdated version of ffmpeg at the time of their release.

  The one you have installed. :) We don't distribute FFmpeg and instead find your installed version at runtime. We support versions 4 through 8.

    That’s a large support matrix. Congratulations. Do you link to the shared object files? Or do you use subprocess?
    • scott_s 3mo ago
      We dynamically load the shared object files. See: https://github.com/meta-pytorch/torchcodec/blob/8bbce656797c4f2b00feb2784ffe76e408be1e4c/src/torchcodec/_internally_replaced_utils.py#L67 https://github.com/meta-pytorch/torchcodec/blob/8bbce656797c... Solutions that shell out to the `ffmpeg` binary are not going to perform well.
