|
||
<p>TRACES: UR-040 | DR-129 | UT-117</p>
|
||
<p>Background audio-only playback of a video item streams a <strong>progressive mp3
|
||
transcode over plain HTTP</strong> (see
|
||
<code>OnlineRepository::build_audio_only_stream_url_for_video</code>). That response has
|
||
no reliable length — a live transcode is chunked — so when the connection
|
||
drops mid-episode the data source simply sees end-of-input. ExoPlayer cannot
|
||
distinguish that from the real end of the media and reports
|
||
<code>Player.STATE_ENDED</code>, which the app then treats as “the episode finished”.</p>
|
||
<p>The user-visible damage is not the missed advance itself. Playback parks in
|
||
ExoPlayer’s <code>STATE_ENDED</code>, and the next play intent from the lockscreen,
|
||
notification or a Bluetooth reconnect goes through media3’s
|
||
<code>Util.handlePlayButtonAction</code>, which seeks an ENDED player to its default
|
||
position before playing — so <strong>the episode starts over from 0:00</strong>. On a
|
||
flaky connection that reads as “it randomly restarts the episode”.</p>
|
||
<p>The player itself has no way to know; the <em>duration</em> does. Jellyfin gives us
|
||
the item’s real runtime, so an end reported well short of it is a truncation,
|
||
not a finish — and the right response is to re-open the stream where it died,
|
||
which is the “buffer and resume” the user expects.</p>
