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();
↧
