Import error on windows for XTTS usage #1147
Description
🐛 Describe the bug
I'm encountering issues on import torchcodec on my windows machine.
I tried with the pytorch version 2.9 cuda 13.0 and with the version 2.9 with cuda 12.8
I was using ffmpeg version 8, found that it might not be supported by torchcodec, so I installed version 7.1, still Issue persists, Nothing works.

Purpose of torchcodec usage: Used by XTTS
-
Error message :
[TTS] Error loading XTTS: Could not load libtorchcodec. Likely causes:
1. FFmpeg is not properly installed in your environment. We support
versions 4, 5, 6, 7, and 8. On Windows, ensure you've installed
the "full-shared" version which ships DLLs.
2. The PyTorch version (2.9.1+cu128) is not compatible with
this version of TorchCodec. Refer to the version compatibility
table:
https://github.com/pytorch/torchcodec?tab=readme-ov-file#installing-torchcodec.
3. Another runtime dependency; see exceptions below.
The following exceptions were raised as we tried to load libtorchcodec:
