What the error usually means

Unsupported format messages usually mean the media player cannot decode the file, cannot read the container, or cannot decode one of the audio or video streams inside the file.

Check the file type and stream

MP4, MKV and AVI are containers. The actual streams may use H.264, H.265/HEVC, XviD, MPEG-2, AAC, AC3, DTS, FLAC or other codecs. The container may be recognized while a specific stream still fails.
