What do you mean after you stopped playing?
Did you just press pause? Close the browser tab?

I just press pause and the tab in background.

@advplyr commented on GitHub (Jan 3, 2022):

I'm sure there are more optimal ways to handle this, but this is how it works right now:

When you open a stream for the first time the FFmpeg command transcodes the audiobook to HLS (stored in /metadata/streams/).
That transcode will run to completion and takes anywhere from a few seconds to a few minutes.

The transcode is canceled only if you open a new audiobook stream OR you close the stream via the X on the audio player.

When opening a new stream or closing a current stream the HLS transcode is deleted.

This means you don't need to transcode every time you press play, only when you first start the stream.
Hope that made sense.

Thank you for your reply.

I think the way to transcode it at first time is fine.

The problem is that my device doesn't have enough memory to transcode. Ffmpeg used all memory and swap. Then transcoding task becomes so low and will never stop.

I will try to add some resource limit on container to avoid swap problem.
