playback on mpv doesn't save progress on Cloudstream

Steps to reproduce

Set mpv as default player.
Play any video for some time.
Close it and try to see if the progress is recorded in Cloudstream.
Resume the video again but it doesn't save progress and will start over again.

However when playing videos on VLC, the progress is saved on Cloudstream as well.

mpv is much faster than VLC, so i prefer using it. Can you please fix this issue in next release?

Expected behavior

Playback on mpv should record playback progress on Cloudstream so as to resume easily.

Actual behavior

Playback on mpv doesn't save playback progress and cannot resume from last position.

Start by tracing the Android mpv playback integration and comparing it with the VLC path that records progress. Reproduce the issue with mpv, then verify that closing and resuming playback restores the last position as it does with VLC.
