QT and Gstreamer appsink



  • I am trying to decode video using gstreamer and get the data using appsink and display in Qlabel.
    gst-launch-1.0 filesrc location=/asd.mp4 ! qtdemux ! h264parse ! omxh264dec ! appsink
    i am able to Decode and display as well but i am more data.
    like if my video size is 640x480 i am getting 460800 bytes in buffer.
    gst_buffer_map(buffer,&databuffer,GST_MAP_READ);
    printing the databuffer.size should be 307200 .
    and in label same image displayed multiple times.
    There may be something wrong in my understating please let me know what is going wrong here.

    Hi,

    You might be interested in the custom GStreamer pipeline for QMediaPlayer::setMedia.

    Hope it helps



  • I have older version of QT5.11.3 and cannot update.
    So want solution for this version.
