Hi I am looking at moving from mp4 to matroska for "encoding" However I have come across a wierd issue wih the title not showing on dlna. When viewed in vlc or parolethe title is displayed as I would expect, however on any dlna client , no title, only the filename is shown. Any tips on how to transcode with a title tag which will show up? example cmdline ffmpeg -v 35 -v 35 -i /Inpitfile.mkv -c:v copy -c:a copy -threads 4 -strict -2 -y -map_metadata -1 -metadata title='Test input' -metadata artist='test' -hide_banner /srv/data/Downloads/outfile.mkv The file plays fine, and the exact same command with mp4 output displays the title as expected. Any ideas?
