Deploy for WinRT

Windows store app is supported since QtAV 1.9.0. QtAV depends on ffmpeg dlls, so you have to deploy all those dlls too. But it seems that Qt does not give us a solution.

Qt5.5 and 5.6 is tested.

• Before Build

Copy ffmpeg development files and runtime dlls to Qt include, lib and bin dir

• Build

You can build QtAV in QtCreator. Visual studio is not necessary unless you want to publish your app.

• After Build

Run sdk_install.bat under build dir

Now Start To Deploy

QtCreator

windeployqt only deploys Qt own modules and files. You have to add QtAV dlls and depended dlls yourself. I find that windeployqt will create AppxMenifest.map which contains the files to be deployed. winrtrunner then reads AppxMenifest.map and creates an app package and install to your device. So you can add your files in AppxMenifest.map.

In QtCreator if you click Run located in the left side, qtcreator will run windeployqt first, all your changes in AppxMenifest.map will be overwritten. So you can click Run only once(the first package is incomplete) to open Application Output panel. There you can clik run/stop without deployment. Then change AppxMenifest.map. At last, click the run/stop button to create a complete package and install to your device.

Of cause, you can run windeployqt and winrtrunner in cmd without qtcreator.

Here is an example to add lines in AppxMenifest.map

"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\qml\QtAV\QmlAV.dll" "QtAV\QmlAV.dll"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\qml\QtAV\Video.qml" "QtAV\Video.qml"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\qml\QtAV\qmldir" "QtAV\qmldir"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\bin\QtAV1.dll" "QtAV1.dll"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\bin\avutil-55.dll" "avutil-55.dll"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\bin\avcodec-57.dll" "avcodec-57.dll"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\bin\avformat-57.dll" "avformat-57.dll"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\bin\avfilter-6.dll" "avfilter-6.dll"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\bin\swscale-4.dll" "swscale-4.dll"
"E:\Qt\Qt5.6WinRT\5.6\winphone_arm\bin\swresample-2.dll" "swresample-2.dll"

If assets folder does not exist in package, add these lines too

"D:\dev\QtAV\examples\QMLPlayer\assets-winrt\logo_store.png" "assets\logo_store.png"
"D:\dev\QtAV\examples\QMLPlayer\assets-winrt\logo_150x150.png" "assets\logo_150x150.png"
"D:\dev\QtAV\examples\QMLPlayer\assets-winrt\logo_44x44.png" "assets\logo_44x44.png"
"D:\dev\QtAV\examples\QMLPlayer\assets-winrt\logo_71x71.png" "assets\logo_71x71.png"
"D:\dev\QtAV\examples\QMLPlayer\assets-winrt\logo_310x150.png" "assets\logo_310x150.png"
"D:\dev\QtAV\examples\QMLPlayer\assets-winrt\logo_480x800.png" "assets\logo_480x800.png"

The first column is the file to copy, the second column is the target path(parent folders are created automatically). The target path can not be empty.

Visual Studio

I find that in your qmake project, you can use DEPLOYMENT var to add additional files to deploy. The official document says this var is only for wince. But winrt seems fine too. Read QtAV/examples/QMLPlayer/QMLPlayer_sdk.pro for detail.

First, you have to create vs project. For example

qmake -tp vc QMLPlayer\QMLPlayer_sdk.pro "CONFIG+=windeployqt"

Then open in vs, build and deploy.
