FF 44 support?

[nerijus]

I recompiled firefox-44.0.1 with firefox.patch, except that 2nd chunk of the 1st file in the patch (dom/media/eme/EMEUtils.cpp) did not apply. But I cannot play test video from https://shaka-player-demo.appspot.com/. Tried both with and without LD_PRELOAD. I put libwidevine.so and widevine.info to /a/firefox/gmp-widevine/1 and launched FF with command:
MOZ_GMP_PATH=/a/firefox/gmp-widevine/1 firefox

[nerijus]

In /proc/26162/map_files (26162 is FF pid) there are links to /usr/lib64/chromium/libwidevinecdm.so when I use LD_PRELOAD, but there is no libwidevine.so, so I assume it is not used?

Are "ClearKey"-labeled videos working on https://shaka-player-demo.appspot.com/ in Firefox-44.0.1? Since Firefox goes through stabilization process, that version could have no required Javascript-side APIs ready.

[nerijus]

No, ClearKey is not working.

Then you need a newer version.

Try snapshot from https://hg.mozilla.org/mozilla-central/file/29258f59e545. You can download archive by clicking on either "bz2" or "gz" links.

I recompiled FF 45.0b4, firefox.patch applied without modifications, and https://shaka-player-demo.appspot.com/ and Netflix works. Thanks a lot!

[i-rinat]

Sounds good.

Will firefox.patch be sent upstream?

Will firefox.patch be sent upstream?

I thought about that, but there are number of reasons against:

1. Patch is a dirty, I-don't-care-just-make-it-work type. It's not ready for inclusion, but requires additional coding effort from Mozilla;
2. As the patch have explicit mentions "com.widevine.alpha", it can cause legal issues, which I don't want to impose;
3. There are already couple of (unrelated to this project) bugreports with ready-to-apply patches, half a year and a year old. But I still have no answers to them, not even a "wontfix". (Those are not of much importance, so I can understand why they are not receiving attention — there are more urgent bugs.) This patch will probably be another abandoned bugreport.

So I don't see any green light on that path.

If however, anybody wants to push it, I have no objections. If there are any license issues, please tell me. I'll make required changes.

ok

Looks like Mozilla is going to add Widevine support: https://blog.mozilla.org/futurereleases/2016/04/08/mozilla-to-test-widevine-cdm-in-firefox-nightly/

Nice work @i-rinat in their changeset they have credited your work. Thanks @nerijus for taking the initiative to make Firefox aware of this good work.
