Video seeking mp4

MHermann

Hello,

I am using Qt5.12.7 on Linux.
I have an application that is playing different videos.
Now I want to move forward and backward while the video is playing.
Therefore I am using the function seek().
For avi it is working. But with mp4 it is not working. The whole gui is freezing.
Does anybody know if seeking has to be handled different with mp4?

Hi,

You should add which version of Qt you are using as well as OS you are working on.

I faced this kind of scenarios, I am using windows and linux systems.

In Linux system is supporting for .mp4 file.
In windows system is supporting for .avi file.

@MHermann how do you play your video? By using Qt code or gstreamer or something else? You may try to upgrade your Qt to 5.15.3 or above at first if possible.

@JoeCFD said in Video seeking mp4:

o 5.15.3 or

I am using Qt 5.15.4 version. and i played the video using qt code.
But I am getting the below output only. But it is not an issue for me.

In Linux system is supporting for .mp4 file.
In windows system is supporting for .avi file.

@JoeCFD: I am using the Video qml type for showing the video. Is there a better way?

@MHermann I use raw gstreamer code + qml sink for video streaming and display. I am not sure you can move video display forward or backward with Qt code directly. But I guess you can do it with raw gstreamer code or FFempeg.
