Bug: Web Player: Attempted Stream of nonexistent file results in unclosable player that keeps trying the file.

[Budlyte]

If a user attempts to play a file that has been removed/renamed but the scanner hasn't picked it up, then the player just keeps hitting the server for the file.

I suppose the player could be closed by attempting to play another book and then stopping, but I didn't think to try it until after.

[advplyr]

The player is using HLS.js under the hood, so it should time out eventually.
This file The Empire's Corps - Book 10 - Never Surrender 2.mp3 didn't exist is what you are saying?

The stream needs to be updated to verify each audio file exists before playing. If an audio file is missing the stream is cancelled and (ideally) it notifies the user and tells the scanner to re-scan that directory.

[Budlyte]

I had renamed the file, but had not rescanned yet, so the player kept trying to hit a filename that no longer exists. That same "WARN: No Segments" went on for a few minutes, it filled up my log screen.

As for the player the Play button just kept spinning. What sort of timeout length should be expected?

[advplyr]

The timeout for HLS.js defaults to about a minute. However, I realized the WARN: No Segments was due to the progress loop in the stream not getting closed when Ffmpeg error quits. That part is resolved in v1.1.12, but the other half of this still needs to be done.
