Description
To reproduce this, run Ensemble and load the "Advanced Media" sample. It will play the following video file:

https://download.oracle.com/otndocs/products/javafx/oow2010-2.mp4

On macOS 10.15.3 Catalina, there is a pause of roughly 1 minute before it starts playing. Then it will play fine for the rest of the video.

You can reproduce this with HelloMedia as well. If I download the file and play it using a file: URL then it starts up fine.

This issue was introduced by JDK-8199527, previous versions are most likely not affected, but I did not verified it.

WAV is not supported by OSXPlatfrom, not sure why. Otherwise should not be a problem.

I can confirm that the forcing OSXPlatform with the above workaround does eliminate the delay. What is the down side of this workaround? Are there formats that GSTPlatform can play that OSXPlatform cannot?

This issue is reproducible with GSTPlatfrom only, OSXPlatform loads file reasonably fast. -Djfxmedia.platforms=OSXPlatform can be used to specify OSXPlatfrom only. GSTPlatfrom to load only GStreamer platform.
