LTXVPreprocess libx264

[sruckh]

Every LTX workflow I have tried ends up with the same error.

!!! Exception during processing !!! libx264

I have tried the 0.9.7 models, both base and quantized. I have the Q8 kernel module installed. I am not sure where I got my text encoders from, but I have placed two different ones in an LTX subdirectory. They have their native names, so I do not know if it is a t5xx encoder or not. From the OS side, I have ffmpeg and libx264-dev packages installed. From the Python side, I have av installed. So I am not totally sure what is causing the error. If there is something I should look at, please let me know.
