Negative duration / negative seeking

It's not a problem with the package, more of a request for help.

Describe the solution you'd like
I am currently building a video editor where you can add an audio track with a certain offset. It can be a positive or negative offset vs the video itself. For the case of a positive offset, it's pretty easy.

Considering an offset of 30s, if I want to seek both video and audio to 10s, I just apply this formula:

videoController.seek(10);
audioController.seek(10 + 30);

But things become quite ugly and complicated when the offset is negative (the sound is starting later than my video).

I was wondering if anyone came to a clean solution where you can control the audio player's internal offset.
For a positive offset, it would just seek to the time + offset.
For a negative offset, it would need to have some kind of "empty sound" padding.

Describe alternatives you've considered
Complicated controllers and streams to keep track of the video current seek to determine if the audio should start playing or not

Additional context
This offset should be programatically changeable on the spot, hence simply adding a "phyisical" padding to the audio on the init is not viable.

@mcosti any update on this?

I ended up using a ticker that checks if the audio should be playing or no.

Quite complex logic but it works.

Unfortunately I cannot really share the code as it's not properly isolated

ok can u do changes in lib for the same?
