Feature: Allowing customization via mpv.conf

[SanmayJoshi]

Current workflow

User has to edit the line local WHISPER_CMD = "whisper.cpp -m /models/ggml/whisper-ggml-medium.bin --threads 6 --language en" in Lua script for their system.

Recommendation

User can specify in mpv.conf

whisper_location=/path/to/model
whisper_threads=6
whisper_language=en

In Lua script, we may modify the WHISPER_CMD as below:

local whisper_location = mp.get_option('whisper_location', '/path/to/model')
local whisper_threads = mp.get_option('whisper_threads', '6')
local whisper_language = mp.get_option('whisper_language', 'en')

local WHISPER_CMD = string.format("whisper.cpp -m %s --threads %s --language %s", whisper_location, whisper_threads, whisper_language)

Note

I wanted to open a PR, however, I was not really clear as to where the whisper.cpp file is to be stored, and whether that also needs to be taken from the user as input via mpv.conf

I don't believe that would make setting this script up any easier. As you would have to make a mpv option for a lot of whisper.cpp args. And this script just uses the main.cpp command-line interface anyways. So I think it would just be simpler to use that as a reference. The only utility I could see using the mpv options instead would be to guardrail the args. Such as --file or --output-csv should never be used, as it would interfere with the script.

Wherever you want. For example, I keep mine in /usr/local/bin/whisper.cpp so I don't have to specify.
WHISPER_CMD is just getting sent to os.execute() like any other command.
