Bug
SUMMARY
When multiple media players are active on the Android device, the KDE Connect
multimedia control plugin exposes the same playback position for all of the
MPRIS proxy players it creates on the desktop. As a result, a short track
(e.g. a 30-second WhatsApp voice message) gets the position of a different,
long-running player, so position >> mpris:length.
The Plasma media controller applet then displays a nonsensical negative
remaining time (see attached screenshot: "-909387748:32" while the position
shows 5:50) and the progress bar is stuck at the end.
STEPS TO REPRODUCE
1. Pair an Android phone via KDE Connect with the multimedia control plugin
enabled.
2. Play a long-running stream on the phone (in my case an internet radio
stream).
3. Play a short voice message (e.g. WhatsApp, ~30 s) on the same phone.
4. Observe the media controller applet / playerctl output on the desktop.
OBSERVED RESULT
All three kdeconnect MPRIS players report the identical position, even though
one of them is a 30-second voice message:
$ playerctl -l
kdeconnect.mpris_430fee4e14594d4cb9d0533a07dc75f3 -> position: 511.597
kdeconnect.mpris_b4b29e3d5ed74009b4e81698be7eb7bd -> position: 511.619
(radio stream)
kdeconnect.mpris_f79969fe31b04322b35cea2189cd5422 -> position: 511.655
(voice message)
Metadata of the voice message player:
mpris:length 30000000 (= 30 s, plausible)
xesam:artist Sprachnachricht
xesam:title Joran
position 511.655 (= 8:31, impossible for a 30 s track)
EXPECTED RESULT
Each MPRIS proxy player should report the playback position of its own
media session on the phone; position should never exceed mpris:length.
