@wjywbs are you interested on send a PR to fix it?

[avelad]

I can reproduce the error

[avelad]

@wjywbs Can you try to disable streaming.allowMediaSourceRecoveries? Could you tell me the new result after that change.

[wjywbs]

The new error is Object { severity: 2, category: 3, code: 3016, message: "Shaka Error MEDIA.VIDEO_ERROR (3,,NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) - Error creating decoder for audio/opus)".

video.js plays h264 and aac.

[avelad]

Sintel works in the unencrypted version. So it seems that Firefox Android does not support Opus+Widevine correctly.

I found that when DRM config exists, such as player.configure({ drm: { servers: { 'com.widevine.alpha': 'anything' } } }), Non DRM videos such as https://bitdash-a.akamaihd.net/content/MI201109210084_1/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.m3u8 can not play on Firefox Android either.
