It affects functionalities in :py:mod:`torio.io`. .. warning:: Starting with version 2.8, we are refactoring TorchAudio to transition it into a maintenance phase. As a result: - Some APIs are deprecated in 2.8 and will be removed in 2.9. - The decoding and encoding capabilities of PyTorch for both audio and video are being consolidated into TorchCodec. Please see https://github.com/pytorch/audio/issues/3902 for more information. )DictListTupleN)dropping_supportreturnc*tjS)zGet the versions of FFmpeg libraries Returns: dict: mapping from library names to version string, i.e. `"libavutil": (56, 22, 100)`. ) ffmpeg_ext get_versionsm/home/mcse/projects/srt_converter/srt-converter-venv/lib/python3.12/site-packages/torio/utils/ffmpeg_utils.pyr r s  " " $$r c*tjS)zSGet the log level of FFmpeg.

The larger, the more verbose. The following values are common values, the corresponding ``ffmpeg``'s ``-loglevel`` option value and desription. * ``-8`` (``quiet``): Print no output. * ``0`` (``panic``): Something went really wrong and we will crash now. * ``8`` (``fatal``): Something went wrong and recovery is not possible. For example, no header was found for a format which depends on headers or an illegal combination of parameters is used. * ``16`` (``error``): Something went wrong and cannot losslessly be recovered. However, not all future data is affected. * ``24`` (``warning``): Something somehow does not look correct. This may or may not lead to problems. * ``32`` (``info``): Standard information. * ``40`` (``verbose``): Detailed information. * ``48`` (``debug``): Stuff which is only useful for libav* developers. * ``56`` (``trace``): Extremely verbose debugging, useful for libav* development.
