Found this bug in JWPlayer 7.12.8.
When VPAID validators (see the links below) try to set volume => 0.9 jwplayer send a method setAdVolume with value in percents, e.g. 0.009000000000000001.
- Volume = 0 => setAdVolume(0);
- Volume = 0.5 => setAdVolume(0.005);
- Volume = 0.9 => setAdVolume(0.009000000000000001);
- Volume = 1 => setAdVolume(0.01);
As you can see, the volume is divided by 100. Previous JWPlayer version 7.10.7 works good and has no this bug. Other validators which don't use JWPlayer also works good.
