gstreamer pipeline to playback as HTML5 backend

[Dece Bel]

Hello,

I am interested in having my gstreamer pipeline (with custom elements doing text analysis for subtitles etc) be used as the backend for HTML5 based video.

Meaning, if a browser with HTML5 capabilities is playing a streamed video, how can I make HTML5 to use my gstreamer pipeline to playback the video. Ofcourse it would mean, installing the pipeline on the machine to be used for playback. 

I could not find any good resource on how to do this.

Gracias

Dece

Hi,

WebKit(GTK,Qt,EFL) already use GStreamer for multimedia playback and so
does (or will?) Firefox under certain conditions.

It would help to know which browser you are targeting.

Thanks Philippe for your inputs. 

What I am looking for is chrome browser on windows. But I am not sure if this is possible. 

The chrome browser needs to be aware of my custom gst pipeline based video player.

Chrome is using its own multimedia backend developed by Google and based
on ffmpeg. Without changing Chrome to implement another multimedia
backend that uses GStreamer you can't do that.

With the GTK/EFL/Qt ports of WebKit you should be able to do what you
want.

Look here for how we do it in WebKit:

https://github.com/WebKit/webkit/tree/master/Source/WebCore/platform/graphics/gstreamer

It's not going to be an easy drop-in replacement though, since we use
playbin pretty heavily.

Is it possible to develop an equivalent of jwplayer which will use gstreamer at the backend?

[Baby Octopus]

And would that be a javascript which would call gstreamer API?
