HTML5 video does not play in demo app about cef.swift

[lvsti]

Hi, which branch are you using? Could you try building and running the cefsimple or cefclient demo apps bundled with CEF (cefsimple target in External/cef_binary/cef.xcodeproj) and see if it can play the same video? The CEF.swift wrapper itself doesn't actually have a say whether something can be played or not, it just translates the APIs to swift.

It turns out that CEF (the binary distribution) was not compiled with the right flags to include proprietary codecs (see http://www.chromium.org/audio-video).
So cefsimple now shows the inline video but when I embed the same CEF framework inside the CEF.swift sample app then it does not work. It looks like cefsimple also links against libcef_lib libcef_dll_wrapper which I do not see in CEF.swift.

Let me get this right, so you recompiled CEF yourself with the proprietary codecs and you tried to link that framework to the CEFDemo app, is that so? Can you give me a branch number and the exact build flags you used?

Btw, libcef_dll_wrapper has nothing to do with the video playback, it is just a mediator between C and C++ code, but CEF.swift doesn't use the C++ API.

I did solve it eventually. The problem was that I copied the cefsimple Helper from the recompiled CEF instead of using the setup.sh from this repo. After doing this it worked fine.

If you're interested I used the following build flags/command to build ref with proprietary codecs:

#!/bin/bash
export CEF_USE_GN=1
export GN_DEFINES="is_official_build=true clang=true dcheck_always_on=true ffmpeg_branding=Chrome proprietary_codecs=true target_arch=x64"

python ../automate/automate-git.py --download-dir=/Users/diederik/Downloads/cefbuild/code/chromium_git --depot-tools-dir=/Users/diederik/Downloads/cefbuild/code/depot_tools --no-debug-build --x64-build --branch=3029

👍 good to know for future reference

@diederikh can you please explain how to put the new CEF binary into project ? I am stuck in this from few hours basically I had successfully made new binary with following flags
ffmpeg_branding=Chrome
proprietary_codecs=true

When I replaced the binary in External/cef_binary with new one its throwing error that
error: install_name_tool: can't open file: External/cef_binary/Debug/Chromium Embedded Framework.framework/Chromium Embedded Framework (No such file or directory)

Its the structure of new binary
