No Mp4 Playback on Release Deployment

@celica said in No Mp4 Playback on Release Deployment:

just to be safe I took everything.

Don't do that. It can cause crashes if you move system DLLs to a different PC with a slightly different version of Windows.

The differential is a lot less now. (around 50 files)

Working - https://easyupload.io/9f8zb0
Not working - https://easyupload.io/38ngbq

I'm still seeing C:\Windows DLLs that shouldn't be in your deployment folder, like C:\Users\USER\Documents\incommand2017\Win32\Release\WINMM.dll.

Please clean up your build folder (delete everything), build your app from scratch, then deploy ONLY Qt files.

BTW, I'm not seeing plugins\mediaservice\dsengine.dll get loaded. That's the one needed to play videos. One thing to try:

Put plugins\mediaservice\dsengine.dll in your release folder but delete plugins\mediaservice\wmfengine.dll
Put plugins\mediaservice\wmfengine.dll in your release folder but delete plugins\mediaservice\dsengine.dll

celica

@JKSH Tried that, still no luck.
Clean build.
I just have a multimedia folder no plugins folder, don't know if that makes a difference -> \mediaservice\dsengine.dll

I notice during the Listdll for when it works in debug it loads lots of codec files which are not present during the Release run, would this matter?

0x0000000005a70000 0x23c000 C:\Program Files (x86)\K-Lite Codec Pack\Filters\LAV\avutil-lav-56.dll

@celica Hi Guys
Still having issues, do you think the lack of codec files deployed during the release build has an effect?

JKSH

@celica said in No Mp4 Playback on Release Deployment:

Sorry, The deployment shouldn't have a "plugins" folder. Rephrasing my last post, try:

Put mediaservice\dsengine.dll in your release folder but delete mediaservice\wmfengine.dll
Put mediaservice\wmfengine.dll in your release folder but delete mediaservice\dsengine.dll

Your folder structure should be something like

app.exe
platform\qwindows.dll
mediaservice\dsengine.dll
...

I notice during the Listdll for when it works in debug it loads lots of codec files which are not present during the Release run, would this matter?

Yes, it kind of matters because those codecs are used to play videos. However, you should not deploy those codec DLLs directly. They should be installed on your PC via the codec installer.

Qt loads the codecs via a mediaservice plugin.

celica

@JKSH Thanks, I tried that. You're right dsengine.dll does not get loaded.
In fact nothing does from the mediaservice folder.
Both from the output window within visual studio after a release build and from the Listdll result when it is running.
Is there any way of forcing it to load this file?

I tried removing the files you mention to no avail.
All the codecs were installed via the codec installer.

Ah, this is an important clue.

That means it's not a deployment issue. Rather, there's something broken in the Release build. Don't bother trying to deploy until the Release build works fine in Visual Studio.

Try setting the environment variable QT_DEBUG_PLUGINS to 1 before running the app from Visual Studio OR from the command line. What messages do you see when it tries to load plugins?

celica

@JKSH said in No Mp4 Playback on Release Deployment:

QT_DEBUG_PLUGINS

Great, getting closer
I'm not sure how to set that variable as I run the app from within Visual Studio 2017
I tried and got this response does this look right?

You could temporarily set it in your PC's global environment. Just remember to un-set it after.

Unfortunately not. It should look something like this:

@JKSH Thanks
I set it within my code using this: qputenv("QT_DEBUG_PLUGINS", QByteArray("1"));
This is what I get:

Note it says defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer

Yes, it's relevant -- it shows that your app has not loaded your mediaservice plugins.

You have plugin folders in 2 places. How did this happen? (The folders should only be in 1 place, by the way)
- C:/Users/USER/Documents/incommandnew/platforms/
- C:/Users/USER/Documents/incommandnew/Win32/Release/platforms/
What's in C:/Users/USER/Documents/incommandnew/Win32/Release/mediaservice?

celica

@JKSH Based on your advice I have totally removed all versions of QT (I had two - 5.5 for a legacy project & 5.12.2 for this project)
Now if I run the application from visual studio in release mode it works fine.
Which was your advice to get that working first.
So that's a good first step I think, thanks,
Now I'll try and delpoy it.

celica

This post is deleted!

@JKSH
Hi, So now it works in release mode within VS.
Videos however still don't play if I deploy using -
windeployqt --qmldir C:\Users\me\Documents\incommand2017\InCommand\Resources\videos C:\Users\me\Documents\incommandCopy\Win32\Debug

Whats weird is if I run the above command then try and run a release build from within VS the videos will also no longer play.
I have to delete all files from the release folder then rebuild the project and then it works again.

JKSH

@celica said in No Mp4 Playback on Release Deployment:

C:\Qt\5.12.2\msvc2017 to C:\Users\me\Documents\incommandCopy\Win32\Release

Great!

windeployqt --qmldir C:\Users\me\Documents\incommand2017\InCommand\Resources\videos C:\Users\me\Documents\incommandCopy\Win32\Debug

Debug or Release?

Whats weird is if I run the above command then try and run a release build from within VS the videos will also no longer play.

Before you run windeployqt, your app tries to load DLLs from C:\Qt\5.12.2\msvc2017.
windeployqt copies DLLs from C:\Qt\5.12.2\msvc2017 to C:\Users\me\Documents\incommandCopy\Win32\Release
After you run windeployqt, your app won't try to load DLLs from C:\Qt\5.12.2\msvc2017 anymore.
After you run windeployqt, your app tries to load DLLs from C:\Users\me\Documents\incommandCopy\Win32\Release

Here's the thing: If windeployqt "forgets" to copy some DLLs from C:\Qt\5.12.2\msvc2017 to C:\Users\me\Documents\incommandCopy\Win32\Release, then your app won't work correctly. Yes, it can miss important DLLs; it is not perfect.

So, use QT_DEBUG_PLUGINS and ListDLLs again to find out which DLLs are missing. Manually copy the missing DLLs from C:\Qt\5.12.2\msvc2017 to C:\Users\me\Documents\incommandCopy\Win32\Release.

IMPORTANT NOTE: You should only manually copy Qt DLLs. Do not touch non-Qt DLLs.

celica

@JKSH Ah I see, that explains it
Ok I will bring the dlls over -

@celica said in No Mp4 Playback on Release Deployment:

Which DLLs did you bring over? List them one-by-one.

Also, my earlier question still stands: What's inside C:\Users\me\Documents\incommand2017\Win32\Release\mediaservice\ ?

celica

@JKSH Ok, I'll do that.
Those files were the status before I brought anything over just to let you know

In C:\Users\me\Documents\incommand2017\Win32\Release\mediaservice\ are the following files:
dsengine.dll
qtmedia_audioengine.dll
wmfengine.dll

celica

@JKSH So the only difference between when it works and when it doesn't (in terms of the QT dlls, I have ignored all windows system files) are the following are omitted when it fails to work correctly but are included when it works.
I wonder why it fails to load anything located in the mediaservice folder

Yep, that's what I found too.

It's very strange... as far as I can tell, all your DLLs are in the right place.

Just as a sanity check, could you try to build the "Media Player Example" (https://doc.qt.io/qt-5/qtmultimedia-multimediawidgets-player-example.html ) and deploy that? Does that work?

I believe you can find the example in C:\Qt\Examples\Qt-5.14.1\multimediawidgets\player\

If that doesn't work, try uninstalling the K-Lite Codec Pack.

celica

@JKSH Tried removing codecs no luck - went through my code to see if anything was amiss. Looks ok.
Did a build from a completely different PC and the same thing happens - fresh installs of VS 2017 & Q 5.12.2

I can run the multimedia player ok - from within QT creator.
Do I need to deploy this example?
The deploy option is greyed out.
