Qt creator convertor

hi,

i record with rosbag a viedeo. I want to viaualize the video in a gui, with a qt creator, but rosbag records only in the Format Mono_8, buti need a rgb format to play the video. How can i decode the video?
I try with this:
@
QImage temp(&( qnode.getThermalImage().data[0]), 320, 240, QImage::Format_Mono);

QImage image;

image = temp;

image = temp.convertToFormat(QImage::Format_RGB32);

ui.lbl_video->setPixmap(QPixmap::fromImage(image));

ui.lbl_video->update();

Hi and welcome to devnet,

hi

the format of the image is mono_8 raw, because rosbag records in the format mono_8. I need another format to show the video in my qt gui, because qt cant visualize the format. I want to to convert from mono_8 to a rgb format
