I’ve been told on Twitter that Vero 4K is able to do hardware decoding of files encoded with 4:2:2 chroma subsampling. However it’s not working with the file I have, in my case the player falls back to a software
ff-h264 decoder. The video stutters and is thus unwatchable.
It is a H.264 1080i25 4:2:2 High@L4 profile video:

The full debug log is pasted here. This catches attention:

Hardware acceleration is set to “Always” for all codecs and works for other videos with different encoding parameters. OSMC has all the latest updates installed as of the day of this post.
