Since recently, it seems to me that JWPlayer is playing the lo-fi version of Youtube on my site. I think that now it plays 240p by default for most of the videos (or maybe even worse resolution like 144p, I can't figure out precisely).
What I know for sure is that previously the picture and the sound were much better (I think that previously it was playing the 360p versions, which I preffer).
In one of the videos that I tested, I noticed that Jwplayer switches from lower to higher quality somewhere in the middle of a song. The change is very noticeable.
I tried different browsers, I cleaned the cache, it doesn't help. I downloaded the latest updates for Jwplayer (its now version 2.1.2), but it didn't help. I changed it's settings from Flash to HTML5, but it shows the Youtube player embeded within JWPlayer, I don't like how that looks. Also, in HTML5 the thumbnail is not shown.
How can I solve this, please? How can I return everything as it was before? I don't remember making any changes to cause this. I'm very affraid that this might be due to some changes within Youtube. I hope it's not. Thank you!
