Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. I cloned the repositorys (qml_ros2_plugin, ros2_babel_fish)
2. I installed all necessary packages
3. I tried the examples (publisher.qml and subscription.qml worked perfectly)
4. I started the usb_cam_node_exe from the usb_cam package (rviz2 received the topic image_raw/)
5. I tried image_subscription.qml example with my Logitech-C270 webcam
6. The QML Window opened and I received this Error: "[ERROR] [1704280468.358788809] [qml_ros2_plugin]: Could not find compatible format for video surface."

Expected behavior
I expected to see a Video feed in the UI

Okay, it seems the current issue is that YUV is not supported.
It would require writing some extra code to convert this to a compatible format for the QML video output.
I've tried adding this by using OpenCV for the conversion but stumbled across another issue with the compression of yuv (see ros-perception/image_common#293).
So, even if I put in the work to support this encoding, it might not work correctly with compressed images.
Hence, for the moment I would advise using a different encoding.
