[Mac / MLX] Hardcoded wrong path typo (ltx-2-mix) and unexpected keyword argument 'fps' in video_vae decode

Environment :Hardware: Mac mini M4 (32GB Unified Memory)Launcher: Pinokio / Manual Terminal

Bug Description :
1.When running manually from Terminal:It raises FileNotFoundError due to a hardcoded typo in the launch scripts/dependencies (ltx-2-mix instead of ltx-2-mlx, and looking for .venv instead of env).

Error errno2 no such file or directory: /users/hushichang/pinokio/api/phosphene.git/ltx-2-mix/.venv/bin/python3.11

2.When running natively inside Pinokio:It successfully bypasses the path typo but crashes right at the end of the video generation phase (during VAE decode and save). The sub-pipeline (ti2vid_one_stage.py / t2vid_one_stage.py) still passes frame_rate=frame_rate, but the updated patches or base class expect fps (or vice versa), leading to a signature mismatch.

Type Error: BasePipeline._decode_and_save_video() got an unexpected keyword argument 'fps'

Suggested Fix :Please fix the naming drift between fps and frame_rate inside patch_ltx_codec.py and the pipeline classes to ensure upstream ltx-core-mlx compatibility.Fix the directory typo ltx-2-mix back to ltx-2-mlx in the internal python executable lookup paths.
