CefSharp3 (master) audio/video support

[Jan Selepa]

Hello everyone,

I am trying to use <audio> and/or <video> tags on a page I'm displaying using the CefSharp.Wpf.ChromiumWebBrowser. I have successfully compiled the master branch and run the CefSharp.Wpf.Example however if I try to run a Javascript function which calls play() on an <audio> or <video> tag I get the "Object #<HTMLElement> has no method 'play'" error. When I run the exact same function with CefSimple (from CEF3 C++) it works fine, but I don't want to write my whole application in unmanaged C++. When I try some HTML5 testing sites like https://www.youtube.com/html5 or http://www.quirksmode.org/html5/tests/video.html nothing seems to be supported when viewing with CefSharp.Wpf.Example even the HTMLVideoElement on the youtube test site has a red exclamation mark next to it. I tried copying the 5 dlls (libGLESv2.dll, libEGL.dll, avutil-51.dll, avformat-54.dll, avcodec-54.dll) from CefSharp 1.25.7 binaries next to the CefSharp.Wpf.Example.exe but that didn't help. Is there any way to get this working please? I'm new to cef and cefsharp so any help would be greatly appreciated.

Thanks for a good explanation of what you tried, makes it easier for others to help!

You need the DLLs that match the CEF version in use is briefly mentioned in the FAQ https://github.com/cefsharp/CefSharp/wiki/Frequently-asked-questions#Runtime_dependencies (admittedly it could be more clear in the FAQ, suggestions are welcome, anyone with a GitHub account can edit the wiki)

The easiest for now is probably to grab the DLLs from the CefSharp/cef-binary repo.

Welcome to CefSharp land!

Thanks for your reply. I was reading the faq before so I don't know how I missed this but it is exactly what I needed so thank you very much.
