See screenshot. Expected results: Video should have played. Videos play okay on stable 54 and beta 55. I don't know exactly when this happened, but 14 days ago, I could play videos when I encountered a different bug 1379389
Forgot to say I'm using a Verizon Ellipsis 10 tablet, Android 5.1, Verizon software update IR7_20C63.
Thanks for firing this bug. Can you still see this bug if you reboot your device?
Further investigation shows Firefox Nightly won't play any video.
Summary: Can't play any Youtube video → Can't play any video

Thanks for this info. John, Could you check this?

This bug has now appeared in beta 55 2015502025.
[Tracking Requested - why for this release]: This issue breaks all playback on some handsets including Huawei's flagship P10 phone.
What phone are you having this issue on?
Thanks to the excellent support from ssergiu@softvision, I've identify the root cause. This is a regression caused by the patch in bug 1365205, which rejects null output buffers. Unfortunately, some decoders return null output buffers when it's configured with output surface and all output buffers they produce were considered invalid .  http://searchfox.org/mozilla-central/source/mobile/android/geckoview/src/main/java/org/mozilla/gecko/media/Codec.java#267
Sounds like this might be a blocker for 55 if it affects popular phones.

Devices: - Huawei P10 (Android 7.0); - Huawei MediaPad M2 (Adnroid 5.1.1). Builds: - Beta - 55.0b14; - Nightly - 56.0a1 (2017-07-31); Hello, Verified this issue and it is no longer reproducible in beta. Nightly still seems to be affected on the P10.
(In reply to Bogdan Surd, QA [:BogdanS] from comment #23) > Nightly still seems to be affected on the P10. Thanks a lot for the verification. Could you please type 'about:buildconfig' in the address bar of Nightly and upload the screenshot?
Sure, here is the screenshot you requested.
Bogdan, thanks a lot for the prompt support. It looks like the Nightly you tested was built from 2017-07-26 changeset which doesn't include the needed patch. Could you please download and install the APK from , and see if it is still affected?  https://archive.mozilla.org/pub/mobile/nightly/latest-mozilla-central-android-api-15/fennec-56.0a1.multi.android-arm.apk
Hello, Thanks John, with the apk provided video playback works without any issue for both mobile and desktop versions of the site. Marking as verified.
