Comment (by Jun):

 Replying to [ticket:7260 julien23]:

 The reason is there in your log: 455 repsonse
 > [rtsp @ 0x56423d973680] UDP timeout, retrying with TCP
 > [rtsp @ 0x56423d973680] method PAUSE failed: 455 Method Not Valid In
 This State

 When UDP timeout and ffmpeg sends PAUSE request to the camera, the camera
 gives 455 back.
 I guess the camera simply does not allow that ?  Do you have more detailed
 logs?
