Qt WebEngine 5.8 & Proprietary codecs with Visual Studio 2015

echelon

The compilation guide from here seems out of date and there is still no noticeable tutorials on how to use the new qt 5.8 build systems, so far it already made me wasting more than 6 hours for the compilation only.

My env variables and batch script snippet are :

The problem is how to enable proprietary codecs on web engine?, on 5.7.x i am just put it on .qmake.conf inside the qtwebengine folder and qt build system will automatically picked it up. But now on 5.8 i could not found a way to do it automatically.

My two variant of .qmake.conf from qtwebengine :

QMAKEPATH += $$PWD/tools/qmake

WEBENGINE_CONFIG += use_proprietary_codecs

# Resolve root directories for sources
QTWEBENGINE_ROOT = $$PWD
QTWEBENGINE_OUT_ROOT = $$shadowed($$PWD)

load(qt_build_config)
CONFIG += warning_clean

MODULE_VERSION = 5.8.1

QMAKEPATH += $$PWD/tools/qmake

# Resolve root directories for sources
QTWEBENGINE_ROOT = $$PWD
QTWEBENGINE_OUT_ROOT = $$shadowed($$PWD)

load(qt_build_config)
WEBENGINE_CONFIG += use_proprietary_codecs
CONFIG += warning_clean

MODULE_VERSION = 5.8.1

But still no luck, the qt configure test still not detecting that i wanted proprietary codecs :

Qt WebEngine:
  Proprietary Codecs ..................... no
  Spellchecker ........................... yes

@echelon What does configure say if you call it with additional -v parameter?

Looks like adding the use_proprietary_codecs define in .qmake.conf is not allowed by design?, i need to add these changes in order qt 5.8 to pick up the additional WEBENGINE_CONFIG :

#Edit ..\qt-everywhere-opensource-src-5.8.1\qtwebengine\.qmake.conf
#Add
WEBENGINE_CONFIG += use_proprietary_codecs

#Edit ..C:\QT-Build\qt-everywhere-opensource-src-5.8.1\qtwebengine\configure.json
#Line 45
