How to check video codec on PC?

When you are troubleshooting video not supported, can’t open video, or unsupported video codec issues, you most likely have thought of video codec. A codec is a software or hardware that compresses your video so it can be stored and played back. Here are some popular video codecs: H.264, HEVC, XVID, DIVX, MPEG-1, MPEG-2, MPEG-4, VP8, VP9, AV1, etc. In addition to a codec, each video file has a container, also called a file extension since they are often seen in file names, such as MP4, MKV, MOV, WMV, AVI, WebM, etc. Since a video codec is hidden behind the container or wrapper, how can I tell what codec a video uses?

Identify video codec in VLC player

In fact, you can directly find out video, audio codecs using some media players, such as QuickTime Player for Mac, VLC media player, etc. VLC (also known as VLC player, VLC Media Player) is a free and open-source, portable, cross-platform media player and streaming media server. It is available for Windows, Linux, Mac OS X, Unix, iOS, Android and more OS.
