[Help] Webkit can't play videos altough gstreamer is installed.

oren_daniel · 06-26-2019, 07:42 AM

I am using a webkit based browser, and I have the following installed:
-gstreamer
-gst-libav
-gst-plugins-base
-gst-plugins-bad
-gst-plugins-good
-gst-plugins-ugly

When I go for example to youtube, and try to play a video I get white screen and a loading circle, after a few seconds I get a screen which tells me that "an error occured".

The strange thing is when I do the same with gnome Web which is also webkit based, everythings works fine.

What should I do to make webkit play videos?
thanks for the help!

And pray tell what is the identity of this browser?
Why do you guard its secret?
Please start it in a terminal, make it misbehave, and show us what it spits out.

Your servant,

Hello ondoho thanks for the quick response

I use a browser called Luakit.
However I am also interseted in embeding a webkit browser in some of my projects so I am asking a general question about webkit.

I tried to open a terminal and run Luakit from there but it doesn't report anything when it misbehaves.

This is what it spits when I open a video, if it helps.

Won't matter what browser that you use.

OK.
What version, on what distro, is the distro up-to-date.
AFAIK luakit hasn't seen any development at all for a few years now. The version in debian stretch is from 2012, they really should just chuck it out

Try surf (although that hasn't seen much development recently either).

I am using both Arch and Debian 9, I compile luakit from source, using webkit2gtk 2.24.2-1, so I am using its latest version.

I know for a fact that luakit can play videos because I once got it working on my last computer.

I tried surf and it also doesn't solve my problem because it is also based on webkit.

As I understand the problem, it doesn't concern which browser I am using because all browsers(which aren't firefox) use the same engine webkit, so I either I am missing a codecs or a decoding package in gstreamer or I have installed webkit differently than the last time I got it working.

If you got video decoding working on surf thats awesome I would like to hear how you achieved it because than I can achieve the same with any webkit based browser.

If you need further information about the distro or package version I will be happy to provide it to you.

youtube-dl is a good idea, and in fact that is what I use now, I am just looking for a more "natural" way to play videos on my web browser.

That is indeed a sufficiently new version of that particular webkit incarnation. But just FYI, there are several.

It also appears that I was wrong: luakit is very much alive; only the version in debian stable is stone old.

I am now installing luakit from the AUR on my arch machine. Did you also do that?
All optional dependencies are installed, both for webkit2gtk and luakit.

Code:

pacman -Qii luakit
pacman -Qii webkit2gtk

Youtube videos play alright:
