Thanks for the report, I was able to reproduce the issue.

Note: The issue is not reproducible on Chrome, where the video plays.

Tested with: Browser / Version: Firefox Preview Nightly 200621 (🦎 79.0a1-20200617093637) Operating System: Huawei P20 Lite (Android 8.0.0) - 1080 x 2280 pixels, 19:9 ratio (~432 ppi density), Samsung Galaxy S6 Edge (Android 7.0) - 1440 x 2560 pixels (~577 ppi pixel density)

Moving to Needsdiagnosis for further investigation.

I can't test it as there is a geolocation limit for this video.

[karlcow]

1. This seems to be about YouTube Movies
2. Both Oana and I can't test because I suspect you need to be in USA for accessing this specific instance.
3. This probably requires to pay to get access to the movie.

Is the trailer working https://m.youtube.com/watch?v=KYrggEA8rSg This is the local channel for Japan https://m.youtube.com/channel/UClgRkhTL3_hImCAmdLfDE4g

And if I access for example the ones with Preview only labels this is working https://m.youtube.com/watch?v=ru63l8_HvNU

[karlcow]

I asked for help inside to see if anyone had YouTube movies account on Firefox Android.

[liamengland1]

It's probably a DRM issue, as youtube movies use drm.

@karlcow you are right, you need to be in the USA to view the movie. The movie is free to watch.

[liamengland1]

Here's the debug info from the player on Firefox Windows if it helps. I don't have an android.

[karlcow]

It would be good to try with the latest nightly. Someone just told me that it was working without issues after adjusting to the latest nightly.

[karlcow]

@softvision-oana-arbuzov Can you reproduce?

[softvision-oana-arbuzov]

@karlcow I can still reproduce it.

Tested with: Browser / Version: Firefox Nightly 201103 (🦎 84.0a1-20201101092255) Operating System: Samsung Galaxy S8 (Android 9) - 1440 x 2960 pixels, 18.5:9 ratio (~570 ppi density)

[karlcow]

Ah this one for @ksy36 I'm blocked from Japan.

[denschub]

These kinds of movies are DRM'ed, and YouTube is using Widevine for that. This video works fine for me with media.eme.enabled=true and media.eme.require-app-approval=false, which makes this a duplicate of https://github.com/mozilla-mobile/fenix/issues/1175
