Magnus Nygren Posted January 4, 2021 Posted January 4, 2021 Hello I'm running a Plex server on my Helios64 and when I turn on subtitles it buffers every other second making the movie unwatchable. Is this a known issue with a fix? Sincerely Magnus Nygren
Remus Posted January 4, 2021 Posted January 4, 2021 Hi there. I'm also running plex with subtitles and no issue. What type of subtitles are you using? Srt?
Magnus Nygren Posted January 5, 2021 Author Posted January 5, 2021 I have convertet my Blu-ray collection with MakeMKV and HandBrake and are using the included subtitles in a MKV file.
m11k Posted January 6, 2021 Posted January 6, 2021 Most likely turning on subtitles converts the stream from direct play to transcoding. From Plex's documentation: Quote Note: Subtitles can introduce a wrinkle here sometimes. Even if a file’s audio, video, and container are all compatible with a Plex App, if a subtitle stream is selected and is not compatible with the Plex App, then the Server will “burn in” the subtitle text within the video. This requires a full transcode of the video stream. I haven't tried personally, but I think the helios64 is too underpowered to be able to transcode full HD video in real time.
gprovost Posted January 7, 2021 Posted January 7, 2021 @Magnus Nygren Until hardware encoding engine is fully implemented for rockchip RK3399, it might a bit too much for the processor to handle a full HD transcoding.
