Video Transcoding when only audio transcoding is needed - SRT subtitles related
I just dicovered an issue with PMS and/or Plex for Androiv TV. I have PMS installed in my NVIDIA SHIELD but the same issue happens with my Synology as PMS so I think issue is related to the Plex Player for Android TV. The problem is that as we know, the NVIDIA SHIELD TV Plex player cannot decode AC3 or DTS like Kodi does. Because of this, PMS transcodes the Audio. The problem is that in my case the Video is also being transcoded for no reason. This does not happen for instance if I use the player on my old Samsung TV (2012 model). TV can decode AC3 using internal player so both video and audio are Direct Play (sigh, on a side note, and even if I understand the reasons, it is just plainly wrong I can direct play most of my videos in the Samsung Plex app and not in a Nvidia Shield.. this needs to be addressed...)
After some testing I think I know the reason, subtitles. If a subtitle is selected when the Audio needs to be transcoded, then the video is also transcoded. I guess subtitles are being burned in, but why? They are in SRT format, no image subtitles. Again, in my Samsung TV using the Plex Player 2.007 all works fine but then again, there it's not transcoding the audio. I have tried the Plex plugin for Kodi. It also Directs Play the audio and video so no problem here either.
I guess this is a bug with the internal player, tried to look for it but couldn't find anything (was also not completely sure which search terms to use). Does somebody know if this is a known bug and whether this is being looked at? I really didn't expect I would need to use alternatives to the official Plex Player in my new Shield like the Kodi plugin or my old TV ... disappointed...
Sorry for the long post, thanks!
