Description

I love the Karaoke option. However, since I'm on Windows it is rather tricky to get working. Would you be willing to change the Karaoke output to a more cross platform compatible option like perhaps what stable-ts does and generate a standard .ass closed caption file. That allows a number of video players to optionally turn it on or off and still allows for easily generating a video with the transcript permanently burned in like the current script does. Also, it is more cross platform friendly.

Thank you for considering my request.

Contributor guide

Research direction
Examine the stable ts implementation to understand how .ass subtitle files are generated from Whisper outputs. Then, modify the karaoke output in whisper.cpp to produce compatible .ass files that can be toggled on/off by video players.
