<p>Pure logic, extracted from the command layer so it can be unit-tested in the
|
|
player core — the sibling of <a href="../seek/index.html" title="mod jellytau_lib::player::seek"><code>super::seek</code></a>. <code>player_switch_audio_track</code>
|
|
turns the resulting <a href="enum.AudioTrackSwitchStrategy.html" title="enum jellytau_lib::player::track_switch::AudioTrackSwitchStrategy"><code>AudioTrackSwitchStrategy</code></a> into a concrete action.</p>
|
|
<p>The rule this module exists to state: <strong>an engine can only select a track
|
|
the stream in front of it actually carries.</strong> A Jellyfin transcode is built
|
|
around one <code>AudioStreamIndex</code>, so the alternate tracks are not in the stream
|
|
at all — the switch has to re-open it. Only a direct play/stream hands the
|
|
engine the source file with every track present.</p>
