HTML5 Video memory deallocation problem

[markov00]

I'm currently facing this problem:
I've created a small html page that reproduce the following problem:

• create an html5 video tag with a small video with autoplay and loop
• after few seconds delete the videotag and recreate it

After 4/5 create/remove/recreate loop, the video stops the playback.
I've written the issue in this repo and not in the wpewebkit because seems a problem related to one of the layers used by WPE.

I've tested and found the same behavior with the following systems:

• RPI3 with yocto and wpe (no special configuration or layer added) using westeros
• RPI3 with resin and resin-wpe
• imx6 with yocto and chromium 48

I'm assuming that it's a problem with GStreamer because it's the only layer that is shared between
a WPE yocto build for RPI3 and an IMX6 board with chromium.

Do someone has ever had this problem? The behaviour of create, remove and reallocate the video tag is because on our production application, there is always a screensaver video that is created after a inactivity timer, and it's stopped when the user touch the screen.

I would suggest to run wpe under gperftools and investigate more. memory leaks are hard nuts to crack.
