I often download youtube videos to watch them later. But some of them does not show any thumbnail and if I try to play them in smplayer it only renders audio and doesn't support video. When I try to open them with ubuntu default video player error message is showing up as shown in the image.
On clicking on find in software it doesn't find anything. I have already installed ubuntu restricted codecs. I know vlc can play this but vlc has other playback issues for me. It is playing in mpv but I want to use smplayer. Any workaround to play this type of video in smplayer? Thanks in advance.
