I have a chromecast 3 and i see all compatible formats here:
https://developers.google.com/cast/docs/media
I have tvheadend 4.2.8-27 on libreelec.
I create transcode/av-lib and I filled it out like pictures 1 and 2.
But when I run tvhclient on my android phone and cast to chromecast (I have paid version of tvhclient) I can't watch the video correctly, I tried with others codecs but is same or I can´t see anything.
I only see the picture 3.
