VP9 codec displayed as "Webm" in video flags
#1
I didn't check in detail to make sure, but in just observing some video files that have VP9 video stream the codec flag is Webm.  Webm is an Mkv container variant, not a codec AFAIK.  The files in question happen to be mp4 files.

Example file ffprobe output:
Code:

I only have one vp9 test video, and I get this on Kodi 18.7, Ubuntu 20.04.

The problem is the texture file in media/flags/videocodec vp9.png should read VP9 rather than WebM IMHO since there is no requirement that WebM container is used for VP9. Though WebM does restrict ("should" not "shall") video codec to VP8 or VP9. I guess I'm saying codec should be codec and not make assumptions about file containers.

If there's interest, one of the things I'm thinking of doing a PR for is an updated set of media flags which would include a proper VP9 flag.

That looks great. Atmos, DTS:X and Auro logos would be good too (If not already included)
