Record Sound and Video using QMediaRecorder
-
One thing is: do you have an mp4 encoder on your machine ?
-
VLC is ffmpeg based.
Qt doesn't provide any codec, it uses whatever the platform makes available.
-
Make them available to Windows. Like I said, Qt backends implementation are platform specific, so you have to install the codecs you want on your system in order for Qt to be able to use them.

Thanks you! i'll try tonight. But if i deploy my software, do i have to install codecs on each computer using my software or does Qt include it during the deployment?
At the moment i am currently working with openCV for the video.
On the audio part, i noticed a problem using QAudioRecorder. when i try to change settings, it's always fail. maybe i have the same problem with QMediaRecorder.
Keep looking for a solution and i'll telle you if i find the solution. Thanks you for your help ;) -
No, Qt won't install such stuff for you, it's up to you to either point the user to where he should get one or make it part of your installer.
What settings are you using ?

Hello, sorry i have been working during the end of years events so i did not work on my own project.
I have currently created a thread using Open CV in order to record video in .avi and i used the Qt's audiorecorder example to record sound. i juste changed it a little but it's fully functionnal.Next step is to merge these two process and to syncronously record video and sound.
I will creat a last thread that will use ffmpeg to merge the two files.happy new year everybody and i wish you a happy coding year !

Finaly, i have finished and it is working!
To conclude :
I used the audio recorder example to record sound.
I used OpenCV to record video syncroniously
at the end of the recording, I used a QProcess in order to launch ffmpeg.Linking it with some signals to a main process which handle all processes.
Well! Problem SOLVED. Thanks you all !
