thanks to amaitland the proper way to actively inforce changing the request-context prefrences, is to run the code on CEF UIThread as following: Cef.UIThreadTaskFactory.StartNew(delegate { var rc = this.browser.GetBrowser().GetHost().RequestContext; var v = new Dictionary<string, object>(); v[“mode”] = “fixed_servers”; v[“server”] = “scheme://host:port”; string error; bool success = rc.SetPreference(“proxy”, v, out error); //success=true,error=”” });
You are missing the Chromium Embedded Framework (CEF) core libraries. It is enough to copy the content of the ..\dcef\bin\Win32 folder (from your downloaded package) into your project’s output directory (or into some of the known folders location reachable from your project’s executable).
Indeed the compile option to support proprietary codecs was moved. the magic now happens here: set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome there is 2 batch files that you should update/create (as found here): c:\code\chromium_git\update.bat: set CEF_USE_GN=1 set GN_DEFINES=is_official_build=true proprietary_codecs=true ffmpeg_branding=Chrome set GN_ARGUMENTS=–ide=vs2015 –sln=cef –filters=//cef/* python ..\automate\automate-git.py –download-dir=C:\code\chromium_git –depot-tools-dir=C:\code\depot_tools –no-distrib –no-build c:\code\chromium_git\chromium\src\cef\create.bat: set CEF_USE_GN=1 set GN_DEFINES=is_win_fastlink=true proprietary_codecs=true ffmpeg_branding=Chrome … Read more
Marshall Greenblatt (the maintainer of the Chromium Embedded Framework) addresses the lack of support for MP3 (and AAC) in Chromium and CEF in this bug report (see comment #7, copied below): Codecs like MP3 and AAC are included in Google Chrome releases but not Chromium builds. This is because these formats are not open and … Read more
You’ve already listed the most notable solutions for embedding Chromium (CEF, Chrome Frame, Awesomium). There aren’t any more projects that matter. There is still the Berkelium project (see Berkelium Sharp and Berkelium Managed), but it emebeds an old version of Chromium. CEF is your best bet – it’s fully open source and frequently updated. It’s … Read more
