Embedded video stop at the last frame showing an infinite loader

Issue Summary

After receiving the i-frame of a public account video, we extract the link of the video and load it inside a WebView. Everything seems to work correctly except for 1 case:

• on a 6.0.0 Android device, some videos stop on the last frame showing an infinite loader.

This is actually happening only on some videos of the channel, we got 1 video working fine.

Reproduction Steps

We actually can't help reproducing the problem, as we're facing it only on one particular device with Android 6.0.0.
We checked the web(s) versions, here's the detail:

• Mozilla/5.0 (Linux; Android 6.0; Poynt-P61B Build/MRA58K; WV) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/44.0.2403.119 Safari/537.36

On the same device, with a different Android version (4.4.4) with these versions every video of the channel works fine:

• Mozilla/5.0 (Linux; Android 4.4.4; Poynt-P61 Build/KTU84Q) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/33.0.0.0 Safari/537.36

Conclusion

Did anyone else encounter this problem? Is there any solution to it?

Start with the Android WebView integration described in the issue and attempt the supplied video on Android 6.0.0 using the reported WebView user agent. Compare it with Android 4.4.4 and the video that works; done means identifying a reproducible cause and verified fix, or documenting the platform limitation if no fix is possible.
