Proprietary Codec Support

Support for proprietary video codecs (e.g. H264) relies on flags being set during the compilation process. As a result it is not possible to use the binary distribution of CEF and you need to build from source yourself.

These instructions are currently Windows-only. OS X version of Cinder-CEF is a work-in-progress and you can reac more about that here

Building CEF from source

The process for building CEF from source is very close to the instructions provided under Windows Setup here

The key differences:

  • We are using VS2015 instead of VS2017
  • In addition Visual Studio and the Windows 10 SDK also we also needed to install Ninja from here
  • At Step 2: don't download depot_tools.zip, just create a directory for it at c:\code\depot_tools - It will be downloaded automatically by the automate-git.py at step 6.
  • Skip Step 3
  • At Step 4 make add an additional Environment Variable CEF_VCVARS with the following value (because we are using VS2015 instead of VS2017)
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat
  • Make sure the following are included in your PATH Variable
c:\code\depot_tools
C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit\
C:\Program Files (x86)\Windows Kits\10\bin\10.0.15063.0\x64
  • At Step 6 - use the following in place of the contents provided
set CEF_USE_GN=1
set GYP_MSVS_VERSION=2015
set DEPOT_TOOLS_WIN_TOOLCHAIN=0
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 --branch=3282 --download-dir=C:\code\chromium_git --depot-tools-dir=C:\code\depot_tools --no-distrib --no-build
  • At Step 7 - use thefollowing in place of the contents provided
set CEF_USE_GN=1
set GYP_MSVS_VERSION=2015
set DEPOT_TOOLS_WIN_TOOLCHAIN=0
set GN_DEFINES=is_win_fastlink=true proprietary_codecs=true ffmpeg_branding=Chrome
set GN_ARGUMENTS=--ide=vs2015 --sln=cef --filters=//cef/*
call cef_create_projects.bat
  • At step 8 - Use the following to create a Debug x64 builds
cd c:\code\chromium_git\chromium\src
ninja -C out\Debug_GN_x64 cef
  • Then Use the following to create a Release x64 build
cd c:\code\chromium_git\chromium\src
ninja -C out\Release_GN_x64 cef
  • Finally we package up a binary version which is interchangeable with the binary described in the README
cd c:code/chromium/src/cef/tools
make_distrib.bat --ninja-build --x64-build
