direct play even when the profile lists only AAC, and neither a <code>VideoAudio</code>

<code>CodecProfile</code> nor <code>MaxAudioChannels</code> changes that. So the client cannot

<p>The reported bug: a source with an E-AC-3 track and a <strong>PGSSUB</strong> default
|

subtitle track. Sending no index let the server honour that default, and since
|
||||
PGS cannot go out as a sidecar it chose <code>SubtitleMethod=Encode</code> — burn-in.
|
||||
That turned an audio-only transcode (the HEVC video was directly supported)
|

into a full HEVC→h264 re-encode, which the server could not sustain in real
|
||||
time: the buffer never grew beyond one segment and playback stalled every few
|
||||
seconds, taking seeking down with it.</p>
|
||||
<p>Asking for no subtitle stream costs nothing, because the app never wanted the

server’s composited version — it fetches the text tracks separately and

renders them itself (UR-020).</p>

<p>The platform list comes from <code>MediaCodecList</code>, which describes ExoPlayer —
|
||||
but the webview <code><video></code> element may be what renders the video, and
|
||||
Chromium/WebKit decode a much smaller set than the platform does. Advertising

the raw list makes Jellyfin direct-play a track the webview cannot decode, and

the user gets picture with no sound.</p>
|
||||
<p>Which renderer gets it depends on the platform. Linux draws video in the
|
||||
element (unless mpv native video is switched on), so it gets the narrow list.
|
||||
Android draws video only in ExoPlayer: it used to follow the
|
||||
<code>experimentalNativeVideo</code> setting, which could send video to the webview, and
|
||||
while that switch existed the narrow list was the only one true on both sides
|
||||
of it. DR-293 removed the webview video path on Android, so there the
|
||||
platform list is the whole answer — it includes the FFmpeg extension’s
|
||||
AC-3/E-AC-3/DTS/TrueHD, which <code>CodecDetector</code> reports alongside the
|
||||
<code>MediaCodecList</code> decoders.</p>
|
||||
<p>This applies to the <em>video</em> direct-play profile only. Audio-only playback
|
||||
really is ExoPlayer’s, so its profile keeps the full platform list.</p>
