Nothing better with SubtitleEditor, Version is 0.54.0-6.3
VLC plays the files fine
have you tried running that file thru ffmpeg (ffprobe) to see if it’s OK
On the whole, this is not a file issue. I tried tens of .mkv and .m2ts with SubtitleEditor, none want to open the black screen for video in the application.
Few months ago I installed SubtitleEditor on another desktop, version 0.54.0-6.1. It has vlc-codec-gstreamer 2.2.6-3.1
SubtitleEditor plays all the files, mkv
However for the m2ts it displays the same error message “Gstreamer plugins missing. The playback of the movie requires the following decoders which are not installed: audio/x-private-ts-lpcm decoder”
but it plays them fine!
Should I try to downgrade to the version 0.54.0-6.1?
