mpv-translate: Add translation to mpv via js scripts

mpv-translate: A Translation Plugin for mpv-easy

mpv-translate is a translation plugin for mpv-easy. Due to its reliance on APIs not supported by the mpv JS script, it can only be used within mpv-easy. To get started, download the mpy-easy-windows-full.zip, which has only been tested on the Windows platform. You can activate the plugin using the shortcut key Ctrl + T.

How It Works

• Export Subtitles: Uses FFmpeg to extract subtitles from the current video and convert them into SRT format.

• Translation: Employs the Google Translate API to translate the SRT files into your desired language.

• Integration: Adds the translated subtitles back into your video.

Please note that the translation process can be slow, taking 5 to 10 seconds depending on network conditions. However, results are cached after the initial translation to improve efficiency.

Future Improvements

Currently, mpv cannot directly obtain all subtitles, necessitating the use of FFmpeg, which increases the program size and does not support remote video. How to extract subtitles to a file by using mpv

Real-time translation experiences may suffer from network delays, and there is a risk of IP blocking.

The mpv JS script's lack of network API support means it cannot function as a standalone script.

interactive-translate

Similar to interSubs, hovering over a word displays the word's info card, left mouse clicking on the word plays the word's audio, wheel clicking displays the line's translation.

You can use ctrl+ito start interactive translation, which is still in its early stages, so for now, you can only use it in the mpv-easy project.
Currently only support English to Chinese, still need other language dictionary and translation api

What is missing in mpv and what does "mpv-easy" add? If a script only works on a fork of mpv then I'm not sure the mpv discussions page is the right place to advertise it.

mpv-easy is a toolkit for developing mpv scripts using ts. It is not a fork version of mpv. mpv uses mujs to run js scripts and does not add network module to it. Currently, it simulates the fetch function in js through the subprocess

You can just call curl with subprocess, it works on every platform.

[ahaoboy]

Yes, currently I use subprocess to call local programs to simulate the fetch function in js, but I don’t use curl because Windows does not install this tool by default. I use rust to make a simple encapsulation.

[guidocella]

curl is installed by default since Windows 10.

Thanks, this means we seem to have a cross-platform command line interface
