As per blog post the package must be up-to-date (45.0.2454.x and newer). Looking at Ubuntu repos it seems that all currently supported releases have that package up-to-date.

Instructions on how to fix H.264 support.

I like that, thanks. I've added it to my bookmarks because I'm pretty forgetful. It works with the beta and dev versions just fine AFAIK. I used a marginally different process but it worked well enough. I've lately been poking at Lubuntu and have been pretty happy so I think I'll stick to this distro for a little while though I'll surely move on to another one soon enough.

• Instructions on how to fix H.264 support.

As a lark I tried it with the Opera beta build and can confirm that it worked. Rather nifty. Thanks for the fix.

Firefox uses gstreamer (may be libav over gstreamer)
And libav is fork of ffmpeg.
So there's no reason for this ...

I hope for a definitive solution soon.

(Excuse me, implementation was not the right term. It's perhaps more of a variant.)

@avl:
Can't you use the implementation of ffmpeg that Firefox use? (OpenH264)

We could use it as an alternative H264 decoder, but notice that OpenH264 is definitely not an implementation of ffmpeg :).

It's a completely different library, and maintaining a video pipeline that uses it would be lots of work (look up how long it took Firefox to integrate it; in terms of Opera, it would be similar to the work needed on Windows and Mac to integrate with their system libraries). In addition, it doesn't solve our problems: although it's able to decode some H264 videos, it doesn't play all profiles, and it doesn't decode any audio, so for most videos you'd still be out of luck. It would be less work (and more rewarding) to try and use the system ffmpeg again.

I've found much simpler workaround than that guide which by the way is totally innacurate because there is no third_party/ffmpeg directory in chromium source code. At least not in Chrome/44.0.2403.107 (Opera Stable) and Chrome/45.0.2450.0 (Opera Developer) even master branch doesn't have that directory.

Yes there is: https://chromium.googlesource.com/chromium/third_party/ffmpeg/

The way you've outlined, copying Chrome's binary library, is indeed the solution we hope to arrive at. But notice that 1) it's very likely to break across versions, as Google makes changes to their ffmpeg version (this is why the .31, .32 is added: the libraries are not expected to be completely compatible with each other, using the wrong version you can easily end up with a crashing Opera - the only guaranteed way is to use the version of ffmpeg as shipped with the matching Chrome/Opera version) and 2) it's scheduled to disappear, as Chrome has now switched to statically linking ffmpeg (so future versions of Chrome will not feature a separate libffmpegsumo.so library at all).

you have to follow avl's guide (https://gist.github.com/lukaszzek/ec04d5c953226c062dac) in order to get H.264 support

Credit where credit is due, this guide was made by Lukasz Jagielski, not by me.

As I've explained elsewhere, Opera can't redistribute this version of ffmpeg ourselves due to licensing issues. However, if someone were to create a PPA containing a package created using the guide above, no one would stop you

Can't you install google chrome then, and use it's H.264 codec?

When you've installed chrome, I think the installation should be here: /opt/google/chrome

http://pastebin.com/CZHWxgEc

you will have to change that symlink when Opera Stable 32 releases to libffmpeg.so.32 and with every new version.

OK.

Create a new file

/etc/apt/apt.conf.d/99ownscript

DPkg::Post-Invoke {"/bin/bash /path/to/opera-ffmpeg-updater.sh"; };

I really hope that Opera developers resolve this bug which I already reported to them a couple days ago.

sudo ln -s /usr/lib/chromium-browser/libffmpegsumo.so /usr/lib/x86_64-linux-gnu/opera/lib_extra/libffmpeg.so.31

However, it's still bad that you have to rename the file after each upgrade...

First you need to either install or download chromium-codecs-ffmpeg-extra package. You will find it in Ubuntu [universe] repo. Than you need to:

1. Create lib_extra directory under /usr/lib/x86_64-linux-gnu/opera/ (for Opera Stable) or /usr/lib/x86_64-linux-gnu/opera-developer/ (for Opera Developer)
2. Next copy libffmpegsumo.so from /usr/lib/chromium-browser/ to the directory created in first step
3. Now rename libffmpegsumo.so to libffmpeg.so.31 (for Opera Stable) or libffmpeg.so.32 (in case of Opera Developer)
4. Restart Opera

After that MP3 and H.264/MP4 are working for me in both Opera Stable and Opera Developer.

That is odd. I never had to compile ffmpeg to have H264 support in Ubuntu. I just had to install ffmpeg.

The problem was that if you had Ubuntu 15.04 and installed the ffmpeg package, it would come with a bug that made Opera crash. So instead we had to compile ffmpeg ourselves, or add another special ppa. But now even those workarounds don't work! As @metallinux said in another thread, this is becoming a nightmare.

'd also like to add that for some reason, YouTube still seems to think that Opera has H.264 support (see youtube.com/html5), which leads to video playback errors when it tries to serve MP4 videos. YouTube still works fine when the videos are served in WebM. Eventually we'll want these issues resolved, but for the time being, is there at least a way to tell YouTube that my browser doesn't support H.264?

I have the exact same problem. Youtube lies about that I have working H.264. On youtube this is fine, because whenever there is a H.264 video it will switch to flash, but on other sites that only have H.264 video, I have to switch to Firefox of Chrome.

And the last update broke Ubuntu 15.04 too, that uses ffmpeg by default instead of the bare libav.

The worst thing is that Opera is the only Chromium browser that gives me problems with the multimedia support. Chromium, Chrome and Maxhton work perfect.
