Testing MPV Snap and FFMPEG Performance ?

One can simply check the performance of the mpv snap for debugging or out of curiosity etc. with the following steps.

** (Ensure apt/dnf etc. mpv isnt installed as it will conflict with the snap mpv)

1) Install vainfo (sudo apt install vainfo)

2) Then in terminal, type vainfo , vainfo gives you the list of codecs and backends supported by your device.
     For Example - VP8 ,VP9 etc.

3) Go to https://test-videos.co.uk/ , and then find videos according to the supported codecs that your
    device supports.

4) For example, My device supports VP8 but not VP9 so i will go to https://test-videos.co.uk/ in the website
    there are options for jellyfish 🪼 and big-buck bunny 🐰 , select any one you like upon click you get a drop-down
    list of the files in various codecs, i chose VP8, then you will get the video files in various qualities and size,
    i selected --> https://test-videos.co.uk/vids/bigbuckbunny/webm/vp8/1080/Big_Buck_Bunny_1080_10s_10MB.webm

5) Now in terminal --> mpv https://test-videos.co.uk/vids/bigbuckbunny/webm/vp8/1080/Big_Buck_Bunny_1080_10s_10MB.webm

6) The terminal logs and the mpv output are your dog-food, cheers 🎉 , also feel free to report issues. 😉😉
