      Hi everyone,

      As the title states, I came across this weird problem. My program loads pixmaps and displays them in labels from both image files and built-in cover from songs, and it worked fine until I commit some updates totally irrelevant to this function. Now the deployed exe only loads PNG format, and JPEG/JPG are loaded only when running from Qt Creator(both debug & release mode).

      I did some research but still remain clueless. Here's what i've tried:

      I checked for the path info it stored by pausing the execution, which are valid and absolute path. /imageformats folder under the deployed folder has all the dlls needed. I also tried clearing & recompiling and redeploying, but none of them worked. The former deployed version also loads pictures right under the same deployed folder.

      Then I tried removing qjpeg.dll from the folder and ran the former version program and it failed to load pics too, but this makes it unable to load JPEG even if I put the dll back.

      My Qt version is 5.15.0, program is compiled with MVSC 2019 x64, running under windows 10 2004. I appreciate any clues provided in advance.

        Use windeployqt to deploy your application. It copies all needed plugins (like the one for jpeg) into the appropriate directories.

          I am using windeployqt, and I've tried redeploying.

            Hi,

            You can run your application from the command line after setting the QT_DEBUG_PLUGINS environment variable to 1.

            That will give you more information about what is happening.

              @SGaist Hi,

              Thanks for the suggestion, but could you show me how to redirect QT_DEBUG_PLUGINS output to a powershell window or a log file, when running the deployed program? I tried qInstallMessageHandler but it only logged null qpixmap warning.

              However, running from Qt Creator gave the result that all plugins are loaded correctly and successfully:

              Line 388: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/imageformats/qgif.dll"
Line 389: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/imageformats/qicns.dll"
Line 390: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/imageformats/qico.dll"

Line 393: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/imageformats/qtga.dll"
Line 394: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/imageformats/qtiff.dll"
Line 395: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/imageformats/qwbmp.dll"
Line 396: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/imageformats/qwebp.dll"
Line 554: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/platforms/qwindows.dll"
Line 625: loaded library "F:/Qt/5.15.0/msvc2019_64/plugins/styles/qwindowsvistastyle.dll"

              I also tried loading qjpeg.dll manully by adding following code then compile&deploy(don't know if it's correct though):

              QPluginLoader loader("./imageformats/qjpeg.dll");
if(!loader.load())
{
    QMessageBox::warning(nullptr, "warning", "qjpeg not loaded");
}

              And the warning box showed up.

                  As you can see the library is loaded. There must be something else wrong are you sure the jpeg file exists on the deployed system. Check with QFile::exists()

                    qjpeg.dll is loaded when running directly from Qt Creator, and the pictures show normally. Problem is the deployed one won't load it.

                    The reason for which I'm sure the file exists is that they are readed from music tag(mp3, flac for example), the music files can be loaded and played, the covers exist , and absolute paths are passed for both function.

                      Please read my post, I never asked you to try to load a plugin with QLibrary - it's simply useless what you're doing there.
                      You should check if the images exists on the deployed machine with QFile::exits()

                        I DO read your posts, and I am saying the images exist on the deployed machine. QFile::exists() is called when I check for music info at program startup, and I am using absolute path in every case - info storing, parsing and saving.

                        This has been tested on different machines, and the first thing I did when this glitch came out is checking for file existence.

                        And I am not loading a plugin with QPluginLoader - it's just a blind try and have been discarded.

                          Please convert the file to a png and see if it works then on your deployed machine. I still think the path may be wrong.
                          Also you did not post the output of QT_DEBUG_PLUGINS to see if the plugin can be really loaded.

                            I tried this but unfortunately the output file is 0 KB. I've set the environment variable and Qt Creator is producing plugin debug output.

                            A few songs use png format cover and they are all loaded correctly, and I am also using a default png cover for those without a cover tag.

                              I would take a look at windbg or similar or compile the program so it opens a command prompt (pro: CONFIG += console)

                              Qt has to stay free or it will die.

                                So this does not help as we know it works there.

                                /edit:

                                I am looking for a way to get output from my deployed program

                                I would take a look at windbg or similar or compile the program so it opens a command prompt (pro: CONFIG += console)

                                CONFIG += console does open a console window, but it only produce plugin debug output when running from Qt Creator(not after deploying, should I try deploy a debug version?)

                                windbg result:

                                CommandLine: "F:\cutexg music\QXGMusic_win10.exe"

                                Does this mean only the basic Qt modules are loaded?
                                I used Dependencies before and it showed the same structure.

                                  WinDbg has also a mode to catch the debug output afaik.

                                  As you see there are no plugins loaded. Is you jpeg plugin really in F:\cutexg music\imageformats ?

                                  Qt has to stay free or it will die.

                                    I'm not a WinDbg expert, but with only these output, your UI probably haven't shown yet, right?
                                    You need to give it a "Go" from the "Debug" menu because it will auto break at the start.

                                      Yes they are, that's why I'm so confused. More output listed below, but still no image plugins loaded.

                                      I've also added config += release to make sure it uses release version plugins.

                                      Here is my deploy folder structure:( sorry images are uploaded to imgur, please click link to see)
                                      root

                                      Inside /imageformats are plugins copied by windeployqt and are release version:
                                      imageformats

                                      And by "doesn't load" I mean something like this:
                                      jpeg not loaded

                                      Running from Qt Creator:
                                      jpeg loaded

                                      There is another phenomenon that might help, as is mentioned in the main post:

                                      I kept a former version exe under the same deploy folder, which had no problem loading jpeg. I moved the qjpeg.dll out of the /imageformats folder, run it and saw the same null pixmap. Then I move the dll back, but this former one still can't load jpeg.

                                      @Bonnie
                                      Thanks for the hint, now it's creating more output:

                                      Seems the platforms and styles plugins are loaded, but still no imageformats.

                                        We need the debug output from the system where the plugins are not loaded.

                                        Qt has to stay free or it will die.

                                          Right before qwindows.dll.
                                          I compared 2 outputs, other lines are the same except some loading sequence. No clue why Qt5Svg is not loaded though...

                                            Again: please find a way to catch the debug outputs (e.g. with qInstallMessageHandler) so we can see what QT_DEBUG_PLUGINS prints out!

                                            Qt has to stay free or it will die.
