  • Qt6.4.1 QProcess cannot call external program FFmpeg [closed]

    21 décembre 2022, par Xingchen

    Based on the official Qt example, slightly modified to call the external ffmpeg.exe for transcoding operations

    


    QProcess *p = new QProcess(this);
QString program = "C:\\Users\\kyrio\\Documents\\Qt_Project\\build-test-Desktop_Qt_6_4_1_MinGW_64_bit-Debug\\debug";
QStringList arguments;
arguments << "ffmpeg" << "-i" << "C:\\Users\\kyrio\\Videos\\222.mp4" << "C:\\Users\\kyrio\\Videos\\223.mov";
p->start(program, arguments);


    


    Run no results, try a variety of writing methods also no results, get the output is empty, and no FFmpeg-related processes under the task manager
    
Try to call cmd, task manager can see the sub-processes under the new cmd.exe
    
command is fine, can be called in the terminal, but need to add ./or.
    
can be successfully run in the terminal

    


    Try prefixing arguments with.\or.\or./, still no response
    
Tried to get the exact path to the ffmpeg.exe file in the program string, still no response
    
I want to be able to successfully call ffmpeg.exe to achieve the video transcoding needs

    


    I have made the "program" exact to ffmpeg.exe and this is still unresponsive.No process, no errorString output.The output of exitCode is also absent.

    


    QString program = "C:\\Users\\kyrio\\Documents\\Qt_Project\\build-test-Desktop_Qt_6_4_1_MinGW_64_bit-Debug\\debug\\ffmpeg.exe";


    


    Running results

    


    I tried to start cmd and connected the errorOccurred signal, but there is no output, it is worth noting that the process cmd appears in the task manager
    
no output
task manager
