The Axis M5525 appears to be Axis' replacement for the P-series PTZ cameras. While the driver is able to stream MJPEG data from the camera just fine, a continuous stream of warning messages are also generated while the image stream is accessed. The message is as follows, with the number of bytes varying somewhat between messages:
Corrupt JPEG data: 651 extraneous bytes before marker 0xd9
These messages are a nuisance!
