Talk: Accelerated Video Playback

MPV
The MPV manual discourages enabling HW acceleration in the config file, saying it can cause problems:
In general, it's very strongly advised to avoid hardware decoding unless absolutely necessary, i.e. if your CPU is insufficient to decode the file in questions. If you run into any weird decoding issues, frame glitches or discoloration, and you have --hwdec turned on, the first thing you should try is disabling it.
If one wants to set it in the config, they recommend hwdec=auto-safe, and say hwdec-codecs=all
is just for testing purposes.
Should we change the section in the page?
