Can't detect Mp4 embedded subtitle

[rmtjokar]

Hi, Thank you for your great work. I have two different MP4 files which seems SE can't detect its embedded subtitle ( PotPlayer and other players can show the subtitle):

Change the extension of those files (with format Matroska) from mp4 to mkv. When the extension is mp4 Subtitle Edit expects an MPEG-4 container, not a Matroska container.
