FULL PRODUCT VERSION :
JDK™ 8u72 Early Access Release
ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.3.9600]
A DESCRIPTION OF THE PROBLEM :
When I placed a YouTube Video in WebView using iFrame API, when internet connection is low (for example 100 kb/s) and video is shorter than 20 seconds video freezes for a while and next it is starting buffering. In normal web browser video is starting buffering immediately - so its problem in WebView. It is problem, because this lag causes desynchronization in real progress video and for example Slider in app showing progress of this video.
REGRESSION. Last worked in version 8u72
ADDITIONAL REGRESSION INFORMATION:
Java version "1.8.0_72-ea"
Java (TM) SE Runtime Environment (build 1.8.0_72-ea-b05)
Java HotSpot (TM) 64-Bit Server VM (build 25.72-b05, mixed mode)
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
- place YouTube player in WebView from Javafx app using iFrame API - https://developers.google.com/youtube/iframe_api_reference?hl=pl
- use (for example) NetLimiter http://www.netlimiter.com/ and limit your internet download and upload to 100 kb/s
- try run your app and play video short video - shorter than 20 seconds, before apear the buffering animation video should freeze for a while
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Video freezeing at the beginning, before it's starts buffering
ACTUAL -
Video freezing at the beginning, before it's starts buffering
REPRODUCIBILITY :
This bug can be reproduced always.
