I am syncing a series to my iPhone and was wondering why transcoding is happening if I sync the file. When playing using the iPhone client app, it direct-plays.
I found this hint in the log:
non-selected embedded subtitle stream 70310 cannot be direct-played
Info XML shows:
<Stream id="70309" streamType="3" selected="1" codec="srt" index="2" bitrate="0" language="English" languageTag="en" languageCode="eng" requiredBandwidths="1,1,1,1,1,1,1,1" displayTitle="English (SRT)" extendedDisplayTitle="English (SRT)"></Stream>
<Stream id="70310" streamType="3" codec="srt" index="3" bitrate="0" language="English" languageTag="en" languageCode="eng" requiredBandwidths="1,1,1,1,1,1,1,1" title="SDH" displayTitle="English (SRT)" extendedDisplayTitle="SDH (English SRT)"></Stream>
What is so special about this subtitle that triggers a transcode and prevents direct-play? Anything I can do to prevent transcoding before sync?
