That's right. Supplement are used to manage complexity by
encapsulating self contained features behind a separate interfaces.<br>

+probably another place in the WebKit layer for Windows, you can

WebKit1's WebView is not used by Safari.<br>
<br>
The WebKit project has two "application layers": an old one named
WebKit1 that handle web pages in-process, and a new one named
WebKit2 that use a multi-process model.<br>

If you want, you can still use WebKit1 by using the MiniBrowser:
Tools/Scripts/run-minibrowser (IIRC it runs WebKit1 by default, but
if not there is a way to get it to run WebKit1).<br>

<div>Does any one of these solutions sound more reliable than

Long term, if you want WebRTC to work in WebKit, it will have to
work on WebKit2. If you just want to prototype something, it might
be easier to use WebKit1 if its implementation is in a better shape.<br>
<br>
Can you clarify your goals? Do you intent to provide patches for
WebRTC support in WebKit?<br>

<div style="word-wrap: break-word; -webkit-nbsp-mode: space;
-webkit-line-break: after-white-space;">Hi everyone,
<div><br>
</div>
<div>I have some updates regarding my enabling of
media_stream and some new question.</div>
<div><br>
</div>
<div>I managed to build the project with the following
options ON:</div>
<div>
<div>
<ul>
<li>ENABLE_MEDIA_CAPTURE</li>
<li>ENABLE_MEDIA_CONTROLS_SCRIPT</li>
<li>ENABLE_MEDIA_SOURCE</li>
<li>ENABLE_MEDIA_STATISTICS</li>
<li>ENABLE_MEDIA_STREAM</li>
<li>ENABLE_VIDEO</li>
<li>ENABLE_VIDEO_TRACK</li>
</ul>
<div>For this I had to:</div>
</div>
<div>
<div>1) copy the content of these folders</div>
<div>
<ul>
<li>WebKit/WebKitBuild/Debug/DerivedSources/WebCore</li>
<li>WebKit/WebKitBuild/Release/DerivedSources/WebCore</li>
</ul>
</div>
<div>into DerivedSources/WebCore</div>
</div>
<div><br>
</div>
<div>2) Add some header and source files to the Xcode
projects. The files were present in the repo, but not
added to the projects.</div>
<div>3) Add some headers to be copied into
WebCore.framework</div>
<div><br>
</div>
<div>Given those changes, I was able to build the
project with both Xcode and the build script;</div>
<div><br>
</div>
<div>I tried running a very basic test that only calls
navigator.webkitGetUserMedia, but the call fails with
the folioing error:</div>
</div>
<blockquote style="margin: 0 0 0 40px; border: none;
padding: 0px;">[Error] NotSupportedError: DOM Exception
9: The implementation did not support the requested type
of object or operation.</blockquote>
<div>
<div><br>
</div>
<div>I went into the code with Xcode’s debugger and
found that the error happens in
NavigatorUserMedia::webkitGetUserMedia (basically the
function’s entrance).</div>
<div>My understanding is that the NavigatorUserMedia is
trying to get the content of a “supplement” for the
key “UserMediaController"</div>
<div>The access to the supplement itself is fine, but
its map only contains one object with a key value set
to NULL.</div>
<div>Therefore the supplement returns NULL, and the
NavigatorUserMedia triggers an error.</div>
<div><br>
</div>
<div>There are some comments in the code about how
supplements work, but not what they are for. Can
anyone enlighten me about this?</div>
<div>Did I miss an initialisation somewhere?</div>
<div><br>
</div>
<div>This was what is blocking me now.</div>
<div>I also have a couple of more generic questions
about the project:</div>
<div><br>
</div>
<div>1) When I build with the script and then with
Xcode, Xcode starts from the beginning, generates new
binaries and links against them. Why are the script
and Xcode not using the same files? It feels like a
waste of time and space.</div>
<div><br>
</div>
<div>2) I had to do a number of modifications to the
project to get here. At some point I will send pull
requests, but I understand most of the people do not
want to have media_stream enabled by default. Does
that mean that for each pull request, I will have to
remove my changes, send the pull request and do them
again?What is the right way of handling this
situation?</div>
<div><br>
</div>
<div>Regards,</div>
<div>J-O H</div>

<div>Cmake is not a build system in itself, it is

No idea, I only use build-webkit and make

A lot of people use Xcode so there must be a
way to get it to work.

</div>
The Xcode project files are not generated,
they are real project files created by
Xcode. WebKit contributors maintain 3 build
systems in parallel: Xcode, CMake, and VS.

<div><br>
</div>
<div>I’m new on this
mailing so I’ll start
by introducing myself:</div>
<div>My name
Jacques-Olivier Haché
(J-O), I’m working for
Temasys Communication,
and I’m entering the
WebKit project to work
on the implementation
of WebRTC inside
WebKit.</div>
<div>For those who would
be following the
WebRTC’s news, I’m
also the main
developer of the
WebRTC plugin released
by Temasys.</div>
<div><br>
</div>
<div>Back to business:</div>
<div><br>
</div>
<div>I was able to
download the project,
build it and run it
inside Safari. I did
not try to run it in a
different browser yet.</div>
<div><br>
</div>
<div>My configuration:</div>
<div>
<ul>
<li>Macbook Air 2012</li>
<li>Mac OS X 10.9.4</li>
<li>Revision 171167</li>
<li>I’m on master</li>
<li>I suppose I’m
using the regular
Mac port as I
didn’t see where
to change from one
port to another
yet.</li>
<li>building for
debug mode</li>
</ul>
</div>
<div>I am now trying to
enable the WebRTC
related features to
get a better
understanding of the
current state of this
part of the project. </div>
<div>I have to say that
I faced a lack of
documentation on this
area. I found the <a
moz-do-not-send="true"
href="https://trac.webkit.org/wiki/FeatureFlags" target="_blank">features
list</a>, a document
about <a
moz-do-not-send="true"
href="https://trac.webkit.org/wiki/AddingFeatures" target="_blank">how
to add a new feature</a> but
nothing about how to
turn a feature on and
off (there is actually
a TODO about that in
the second link).</div>
<div><br>
</div>
<div>I looked into the
files that one needs
to change to add a new
feature and found two
interesting files:</div>
<div>
<ul>
<li><span
style="background-color:rgb(255,255,255)">Source/WTF/wtf/FeatureDefines.h
- where the
WebRTC related
contants were
set to 0 instead
of 1</span></li>
<li>Source/cmake/WebKitFeatures.cmake
- where the
contants were set
to OFF</li>
</ul>
</div>
<div>I listed the
following definitions
that look related to
WebRTC</div>
<div>
<ul>
<li>ENABLE_MEDIA_CAPTURE</li>
<li>ENABLE_MEDIA_CONTROLS_SCRIPT</li>
<li>ENABLE_MEDIA_SOURCE</li>
<li>ENABLE_MEDIA_STATISTICS</li>
<li>ENABLE_MEDIA_STREAM</li>
<li>ENABLE_VIDEO</li>
<li>ENABLE_VIDEO_TRACK</li>
</ul>
</div>
<div>I turned those
definitions to 1 and
ON in the respective
file and tried to
build.</div>
<div>The code in the
header
WebCore/Modules/mediastream/mediastream.h
could not compile
apparently because the
observer did not have
a destructor. I
created one:</div>
<div>
<div> class
Observer {</div>
<div> public:</div>
<div> virtual
void
didAddOrRemoveTrack()
= 0;</div>
<div> virtual
~Observer() {};</div>
<div> };</div>
</div>
<div><br>
</div>
<div>and tried to build
again.<br>
<br>
</div>
<div>I now have a
linking error when
building WebCore with
Xcode. </div>

This code has not been updated

The first error could simply
be because the files defining
those symbols are not included
in the XCode project file.
Nobody has worked on WebRTC
for a while, it probably only
builds for GTK.<br>
<br>
The second error is likely a
problem with the incremental
build. I would just delete
WebKitBuild and start a clean
build.<br>

Yep, that's weird. I only run
into problems with precompiled
headers when I change my SDK.<br>
But after changing feature
flags you often have to do a
clean build anyway. There are
too many code generators that
are not tracking these kind of
dependencies.<br>
<br>
Good luck!<br>
