'original' videoplayer (BETA) doesn't close (transcoding) stream after closing

[andries230]

Describe the bug
When using the 'original' videoplayer (BETA), a transcoding stream does not stop after closing the player until you start a new stream.

System (please complete the following information):

• iOS Version: 17.5.1
• Jellyfin Expo version: 43.0.0
• Jellyfin Server version: 10.10.3

To Reproduce

1. Top the Settings (cog) in the tabview
2. Enable 'use original videoplayer (BETA)'
3. Start a video that needs transcoding
4. Look at the system resource monitor (or GPU monitor) so check if transcoding is doing anything
5. Stop the video by clicking the X in the corner
6. Look again at the system resource monitor (or GPU monitor). It is still performing the transcode...

Expected behavior
The stream (and thus the transcoding) should stop when you close the videoplayer
