Hello!
Whatever I tried, my Kdenlive doesn’t play sound and doesn’t make projects exiting with such error: [NULL @ 0x7fb6740c6de0] Requested output format is not a suitable output format. I tried to choose different formats. I changed version from different repositories, I changed versions of it’s dependencies. Now I have Kdenlive5 and it’s dependencies installed from wolfi323 repository. I suppose the problem is in FFmpeg, but I can’t get it.
