Does it work with media.webm.enabled=false ?

Comment 2

[Vlad Bacia-Mociran [:VladB]]

Hi,

I've just tried the same scenario with media.webm.enabled=false and the issues is still reproducible. Nothing has changed in the behavior of the video player.

Thank you.

[Anthony Jones (:ajones, :kentuckyfriedtakahe, :k17e)]

Is anything interesting being logged to the console?

I've retested this issue on Win 10 and Win 8.1 with latest Nightly (Build ID: 20161030030204, x64 and x86) using Widevine CDM 1.4.8.903 and when I press "Play" button from the video/episode page, the screen with the licence rights is displayed and after that, I am notified to enable/install Silverlight plugin.

This is the log from the Browser Console:

This issue is reproducible also when faking Chrome User Agent with User-Agent Switcher, with Chrome browser the video can be played without any problems.

Attachment: hbogo error silverlight disabled

This issue is still reproducible. Are there any updates on this issue?

From Nightly v52 the NPAPI plugins except Adobe Flash are no longer loaded. This includes also Silverlight, which is required in order to play videos from HBOGO.

In Google Chrome this issue is not reproducible.

Comment 8

[Chris Peterson [:cpeterson]]

cpearce, do you know why HBOGO.ro would still try to use Silverlight when Firefox is spoofing the Chrome User-Agent? HBOGO.ro uses Widevine in Chrome.

Comment 9

[Chris Pearce [:cpearce (Not reading bugmail)]]

By default User Agent Switcher spoofs a version of Chrome that supports a version of EME incompatible with our implementation. Try spoofing Chrome 55.

Attachment: cannot play video on hbogo.ro through widevine using agent switcher add-on

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64; rv:54.0) Gecko/20100101 Firefox/54.0

Using latest Nightly v54.0a1 (Build ID: 20170212030213) I've spoofed Chrome/56.0.2924.87 in User-Agent Switcher add-on and the videos cannot be played. The videos cannot be played in latest Firefox release and latest Nightly with or without User-Agent Switcher add-on. 

In Google Chrome all videos are played successfully and without issues.

Comment 11

[Chris Pearce [:cpearce (Not reading bugmail)]]

Maybe they're not using Widevine modular (i.e. EME), and are instead using the old-fashioned Widevine Chrome plugin. Some streamers in New Zealand do that. I can't play Romanian content. Can you try collecting some NSPR logs for me? You need to set the environment variables NSPR_LOG_FILE=%TEMP%\firefox.log MOZ_LOG=EME:5,GMP:5,CDM:5,sync,timestamp and then repro the bug. Then you need to copy the logs out of the system temp dir.

[Chris Pearce [:cpearce (Not reading bugmail)]]

There weren't any other log files there from the content process or plugin-container process? It looks like that site isn't using EME; we should see logging about CDM processes being launched, and it's not there.

I think we can only conclude they're not using Widevine via EME.

Comment 14

[Vlad Bacia-Mociran [:VladB]]

I've tried again and there were some other log files that I've missed the first time (firefox.log.child-1, firefox.log.child-2 and firefox.log.child-3). Maybe these logs are more helpful.

firefox.log.child-1 - was empty

OK. Also in those logs we don't have evidence of EME being used. So I think we can conclude they're not using Widevine via EME.

Is this still the case or can this bug be closed?

Verified on latest Nightly 97.0a1 (20220110093702) and Release 95.0.2 (20211218203254), on https://play.hbonow.com and https://hbogo.ro. The videos are playing without errors. I will mark this bug as Resolved - WFM.
