Bug Severity
Usability is affected
Bug Area
Denshi (Desktop app)
Bug Description / Steps to Reproduce
When using torrent streaming with MPV as the external player, autonext/autoplay
fails to load the next episode in Seanime Denshi. MPV stays open and idle but
Seanime never sends the next episode to it.
Steps to reproduce:
- Use Seanime Denshi (Electron desktop app) on Windows
- Set MPV as the external media player
- Start playing an episode via torrent streaming
- Wait for autonext to trigger at the end of the episode
The same setup works perfectly on the server version.
Expected Behavior
Autonext should seamlessly load the next torrent stream episode into the
already-open MPV instance, the same way it works in the server version.
