Hello,
I made the move to babylon-master version 2.4 last night, and found that all of my videoTextures would not play back correctly. And by correctly, this means that there was no video images playing, only what appeared to be odd decompression artifacts. I don't have time to build a playground scene today, but if this isn't obvious to anyone else, I can certainly build a PG scene tomorrow to demonstrate. Although I'm certain you'll see the problem, as I tested with 3 different video formats, resolutions, and scaling values.
