Ruarí's thoughts

What about mplayer and succerssor of mplayer-plugin: gecko-mediaplayer? It will be implemented in the future releases. IMHO mplayer is more popular than gstreamer (but I could be wrong).

Does this include the H.264 codec as well?

Will it be possible to get the full GStreamer (including H.264) on Windows?

@Hades32: Your question is better placed in that blog as well. I don't run Windows but Philip could probably answer you as to the plans.

Thanks.

No, the codec is in "gstreamer0.10-bad-plugins" package (or equivalent), but for me it only plays audio track.

@tomassplatch
Same here.

P.S. Do you also have the good package(s) installed? See my updated blog post above.

I guess I do:
http://files.myopera.com/tomassplatch/files/gstreamer.png

I have all files you named in /usr/lib/gstreamer-0.10/, and many more, including "libgst264.so", which is responsible for decoding H.264 (I guess?).
Still, I can only hear audio, when trying to play youtube videos...

Works here on Opensuse, very nice.
(good to see that Google fixed the html5 youtube page)

Thank you, working nicely now, although the controls of the video player are a little garbled.

It's annoying, I just installed the last snapshot (6240), set YT to use HTML5 video and it still wants to serve me using flash, and Opera can't open flash, the plugin simply crashes. That's the problem of flash and 64 bit . I should have everything that is needed for video on YT, gstreamer-base, -good and -ffmpeg, but still flash video, that obviously fails.

Edit:
Strange, some video's are served with flash, others use HTML5 Video. I do get video, but no audio. I'll install the gstreamer-bad and -ugly, hope that will get things going.
Installed both ugly and bad, got audio after browser restart. No idea which one is responsible for the audio part though.

Another edit:
gstreamer-bad is responsible for the audio on YouTube, gstreamer-ffmpeg does the video.
Sidenote, I use Ubuntu. Others may need to look for the packages with similar names. Of course, I abbreviated the packagenames compared to the Ubuntu ones .

"you want a package that has a name something like one of the following: gst-plugins-ffmpeg, gstreamer-0_10-ffmpeg, gstreamer0.10-ffmpeg or gstreamer-ffmpeg"

It must be, that if someone would reverse-engineer proper Visua C++ settings, he'd be abel to compile needed GStreamer codecs and copy them into Opera GStreamer folder, adding support for MEPG4 video for Win32 Opera as well.

Can any Linux-savvy man suggest:
1) what GStreamer codecs need for MPEG4 to be played, both MPEG4 Simple aka xvid/divx and MPEG4 Advanced aka H.264 or ffmpeg codec alone is enough?
2) container on YouTube HTML5 is .mp4 with is reduced version of Apple .MOV ? What GStreamer pugin needed to support it, or ffmpeg codec alone is enough ?
3) sound on YouTube mp4 is mp3 (MPEG1 Layer 3) or mp4 (MPEG2 layer 4) or whatever ? To play it - which GStreamer codecs needed or ffmpeg codec alone is enough ?
4) is GStreamer-ffmpeg self-contained ib or it is bridge between GStreamer framework and standalone ffmpeg framework ? In other words, after probably-successful compiling GStreamer/win32 should one find and install compatible ffmpeg lib for Win32, or it is enough already ? i wonder if http://ffdshow-tryout.sf.net is enough...

Thanks in advance for clues.

1) I use mplayer, that plays everything you need as it has the codecs build in. No matter what I throw at it, it all works. WMV is the only thing that doesn't work by default, you need the win32codecs installed, it's a restricted package due to licenses on the codec. If you have a capable videocard and supporting driver, you can use that to decode the video too.
If you use Totem or other gstreamer based players, you might want to install bad and ugly along with base and good. That means all of the gstreamer parts. Maybe ffmpeg is enough for it, no idea. It's all a try or die thing. Keep installing gstreamer parts until you get what you want (video and audio).

2) See my post above for the needed gstreamer packages.

3) Same as 2).

4) The package gstreamer-ffmpeg is separate from ffmpeg itself. FFmpeg can also encode files. The gstreamer libraries are just the decoder parts from ffmpeg.

I don't know about the FFDShow tryouts. They are based on ffmpeg, that's true, but I doubt it will be enough to make it work for Opera. Haven't tested it myself though, you're free to try it yourself. Keep in mind that if you use Linux, FFDShow has no value for you, it's for Windows.

> If you use Totem or other gstreamer based players
That requires me to install Linux and play with it for a while.
I hope someone already using Linux and experienced in it would hepl by just telling what is needed.

> It's all a try or die thing
Not exactly, when you open movie with Windows Direct X player, you can run GraphEdit that will show you all the chain of codecs used. So you do not have to install/deinstall and try and retry, you just run the movie and look which codecs actually been used.
I remember few years ago similar tool was in gstreamer-devel.

> The gstreamer libraries are just the decoder parts from ffmpeg.
You see, they must be statically linked or dinamically linked.
In other words, self-contained or dependant.
In other words, ffmpeg framework and decoders must be compiled inside binary file of gstreamer-ffmpeg and then gstreamer no longer needs separate ffmpeg at all; or it may be that gstreamer-ffmpeg does not have any ffmpeg code inside, and it just looks for installed separate ffmpeg, loads it and translates all requests from GStreamer to ffmpeg and back.

> that if you use Linux
i am talking about making Opera/Win32 support H.264
surely i do not use Linux, Opera/Linux already supports it :-)

> but I doubt it will be enough to make it work for Opera
surely Opera would not work with niether ffmpeg nor ffdshow-tryout
the question is "how to locate and compile GStreamer part that plays H.264 and that it works in Windows and that it is compatible with GStreamer/Win32 port made by Opera"

You made it appear you were using Linux alongside Windows. Didn't I already tell you what gstreamer parts are needed for HTML5 on YouTube? You can then check which codecs and all are in them.

Gstreamer has the same idea. It detects the codecs it needs and prompts you to install the corresponding gstreamer package that holds the codec. Media players have the same function as some on Windows: tell you which codec is used. It's not that hard to figure out. On Windows, you can use whatever you want, like GSpot or Media Player Classic. WMP does NOT have this feature though. Or not well implemented anyway, it might only show you which codec a file has, if the codec is already installed.

What part of my reply did you not understand? Didn't I clearly state that you DO NOT need ffmpeg to be installed?

Didn't you want to know how it works on Linux? I answered those parts, don't give an ungrateful reply and burn me down, ok? You sounded like a jerk to me and I don't want to have a flamewar here. You're also going off-topic, this posting is about the HTML5 video on LINUX, not Windows. The forums might be a better place to continue.

> You made it appear you were using Linux
few years ago, then i had to program in Win32 and had no time for Linux
But i hate C++ and am not right person to go in that complex matters ffmpeg/gst/opera :-)

> You can then check which codecs
On Windows - only Ogg+Theora+Vorbis - those that Opera Software bothered to port.
There is no vanilla GStreamer on Win32, Opera made it's own port.
And you know that when porting some C/C++ soft every litte swtch in compiler might made two libraries binary incompatible. Name mangling, types' sizes, etc.
Since i'm Pascal/Delphi man, i don't want to jump into that well.

> it might only show you which codec a file has, if the codec is already installed.
I know how to do it in Windows/DirectX! Don't chew me that basics of DirectX, u claim me impolite but is it polite of you to do so?
Be it in Windows, i could easily write down all the loaded codecs and all the loaded DLLs (.so's). But i can not do it in Linux right off.

And here it was reported that on Linux you also do have all required codecs in GStreamer vanilla.
So please, can someone run H.264 from YouTube/HTML5 via GStreamer/Linux and look which codecs been used ?

> Didn't I clearly state that you DO NOT need ffmpeg to be installed?
no, not until now.
Separate might easily mean separate RPMs/DEBs - but surely they are.

> The forums might be a better place to continue.
I'm pursuing there to. But there i try to find programmers who can and want do Windows part.
Here i try to get information they might need, and this information is Linux-related because it works on Linux right off.

I am not asking here how to do Windows porting.
But i am asking what to aim at, what is the state in Linux wher it works and what is the state needed to achieve by any Windows porters' team.
Just that.

Im using Debian Lenny and have these gstreamer packages installed: "gstreamer0.10-alsa, gstreamer0.10-ffmpeg, gstreamer0.10-plugins-bad, gstreamer0.10-plugins-base, gstreamer0.10-plugins-farsight, gstreamer0.10-plugins-good, gstreamer0.10-plugins-ugly, gstreamer0.10-tools, gstreamer0.10-x, gstreamer0.10-gnomevfs" I cannot confirm, that it is working for me in other browsers, because in my Iceweasel 3.5 (Firefox) I even cant watch youtube HTML5 videos at all... But video: http://snapshot.opera.com/resources/BigBuckBunny.html works as expected in both Firefox and Opera. Because of this, I know, that this might be a Youtube problem, not the Opera's one, but I want to know, if there's anyone for who the Youtube HTML 5 video it is working properly, or anybody who can help me...

I got less packages installed for Gstreamer (noted above). There are some video's that are smooth, but some aren't. HTML5 takes a lot of CPU too on my end, so that might have something to do with the crackling. Are you using Pulseaudio or not? I am, and that adds another overhead layer.

mnicky writes: No, I dont use Pulseaudio, just Alsa. You are right... Ive managed to find some HTML 5 videos on Youtube that dont crackle. But strange thing is, that when watching one such video, my Opera consumes just 70MBs of my 4GB RAM and 17% of CPU, whilst watching another HTML 5 video consumes about 50% of CPU (= all the one core) and it doesnt crackle... Btw, my bandwidth is about 4 MB/sec...

mnicky writes: My comment above is a little confusing ;-). By the first video (that consumed only 17% of CPU) I mean the video, that IS crackling.... and the second one isnt crackling... And Ive also found, that those videos doesnt flicker, just crackle. It just appeared to me to be so...

Please add phonon-backend-gstreamer to you list. This is package for guys who use Phonon.

Anonymous writes: @GREY the GStreamer back-end for Phonon is only useful when the applications uses Phonon (like Amarok), but Opera uses GStreamer directly, which is better, as the current state of Phonon is not so good as it was expected to be some year ago. Also, Qt is not developing Phonon anymore, they now support QtMultimedia and QtMobility.

thanks for the info .

will try to install the package

Anonim writes: Hi, are there any progress on fixing issues with other codecs in video tag implementation in Opera under Linux. I can play for example h264 (.mp4), but after about 5 seconds movie stops. So essentially it works, but there is some minor issues to be resolved. I know Opera is against adding h264 support, and I agree webm is better way to go, but why preventing people from using it if they really want (and gstreamer already have decoder for it, as well other formats). Thanks.
