ai subtitles

requirements

• ffmpeg
• mpv
• yt-dlp (if streaming video)
• whisper.cpp
• pre-compiled binaries for windows users can be found here
• if you have an nvidia gpu I highly recommend using the cublas version (requires cuda)
• compiling with vulkan support is also possible as a cross-vendor solution
• whisper model
• medium is supposed to be the best for non-english transcription and runs fairly quick even on older hardware
• users with higher-end hardware may also want to try out large-v3
• whisper.lua (haven't tested on windows, but it should work fine)

method

1. identify the appropriate mpv config location for your operating system
2. create a directory called scripts in the config location and save whisper.lua to it
3. open whisper.lua in a text editor and locate the WHISPER_CMD variable
4. edit the variable so that the executable name matches the one you downloaded
5. edit the variable so that the -m option points to the whisper model file you downloaded
6. open a video with mpv, pause it and wait for the cache to fill up to 20-30 seconds (use i to view the cache status)
7. unpause and use shift+w to run whisper.lua
