As question come quite often, just want to show how it works on my peg1/ghz with current state of 1.23 port (i.e. no overlay):
https://www.youtube.com/watch?v=IvCAApLiEkA(be sure you set to 720p when watch, to see everything normally).
On that video i use
youtube-center script, which able to play everything on youtube which i even try. You just add it to scripts, and do restart of odyssey , and when you come to youtube you have new preference-button at top right area where you change settings of script. Those ones i use so it all looks fine and fast enough on my setup:
Player/General/PlayerType: html5
Player/Resolution/EnableAutoResolution: ON
Player/Resolution/AutoResolution: low definition(240p)
PLayer/PlayerSize/EnableResize: OFF
PLayer/PlayerSize/DefaultPlayerSize: Default
PLayer/PlayerSize/SmallResizeButton: Default
PLayer/PlayerSize/LargeResizeButton: Default
PLayer/PlayerSize/PlayerAspect: Default
If you want auto-repeat of vids:
Repeat/General/AutoActivateRepeat: ON
Loading always 100% for me when yt plays, but that kind of expected for sw-cairo + 1ghz of cpu without using of overlay
Also there show standard player speed, large player speed as well as jump between few vids, so all can be seen how reacts and what speed are.
Probably on x1000 can be set to 360p/480p, but as for low-end ones: dunno. Probably nothing can be done but only overlay.
