Tutorial ======== The basic user interface is simple and intuitive and is based on drag'n'dropping the cameras into views. 1. Manage Cameras ----------------- First, let's register some RTSP cameras. - Navigate to *Configuration / Configuration Dialog / Camera Configuration* - Choose a slot for the camera - Choose *RTSP Camera* from the drop-down menu - Type in the camera information (ip address, user, password, etc.) - Remember to enable recording if you want that (see "6. Playback" below) - Repeat for all cameras - Press *SAVE* - Close the window from the upper-right (X) as usual You should also give an estimate of the number of hd-ready, full-hd, 2K etc. streams in *Memory Configuration* tab, as Valkka pre-reserves all resources. That can be done in: - *Configuration / Configuration Dialog / Memory Configuration* 2. Viewing Cameras ------------------ Let's see a list of installed cameras and view their live video - Navigate to *View / Camera List*. The camera list widget appears on screen - Navigate to *View / Video Grid / 2x2*. A 2x2 grid appears on the screen - Drag and drop cameras from the camera list widget into the 2x2 grid - You can open as many video grids on the screen as you please - Note that even if you view the same video in multiple grids, the camera stream is decoded only once - Note that you can also do drag and drop between video grids - Double-clicking on the video, maximizes the video size - Double-clicking again, restores the normal size 3. Removing Cameras ------------------- - Right-click on a video in the video grid - Choose *Remove Camera* 4. Saving and Loading the Layout -------------------------------- Camera views can be saved, and recovered for the next time when you use Valkka Live - Navigate to *File / Save Window Layout*. Now your view layout is saved - When starting the program again, navigate to *File / Load Window Layout* 5. Machine Vision ----------------- - Open a machine vision terminal from the *Machine Vision* menu - Drag'n drop a camera to that terminal 6. Playback ----------- *NEW* The experimental playback feature is now enabled by default. Do the following to see the recorded video: - Navigate to *View / Playback Video Grid / 2x2* - Drag'n'drop the camera you want to see recorded video for into the grid - Click your mouse in the timeline where you want to seek. Use the mouse wheel to zoom in/out in the timeline - When you press the "limits" button, the timeline zooms within the limits of all your recorded streams You ideally want 1-2 key-frames in a single block in order to achieve efficient seeking of the recorded video. Blocksize can be adjusted in: - *Configuration / Configuration Dialog / Recording Configuration* We recommend adjusting your camera's keyframe interval to one keyframe per second and then setting your camera's bitrate & valkkafs blocksize accordingly.
