Transcode Errors (Samsung Tizen)

Started getting a lot of transcode errors (on what should be direct play).

Log file shows a whole heap of these when it happens. This is about 30min into a 1 hr show. You press play again and you get another 5 seconds of the show before it crashes again.

I redownloaded the file and same problem.
Seems to play fine in VLC.
Have tried disabling HW acceleration (but it should be directplay)
Any ideas please.

May be related, but I have in the last few weeks started getting transcode errors on simple h.264/aac tv shows about 2 mins from the end.

Server Version#: 1.32.3.7192
Player Version#: Tizen Samsung (latest)

**Note - Appears to be a subtitle BUG **: Setting subtitles to NONE instead of english forced seems to fixed this issue.
MKV contains: Video Track, English Audio. English Forced Subtitles (srt) and English non-forced CC Subtitles (srt).
Extracting subtitles to external and renaming to .en.forced and setting subtitles to the external forced track also seems to fix.

Have also tried (none of which made any difference):

  • H.264 instead of H.265
  • AAC 2.0 Audio instead of EAC3
  • Beta server 1.32.4.7195
    Workaround is to set subtitles to external. Hopefully a fix will be forthcoming.

Confirming the same issue on both Xbox Series S and Vidaa (Hisense tv).
Turning off the subtitle helped.
Otherwise, it will crash everytime ~3 minutes left of the video.
