How to Play the Video Recorded by xf305 Camera

The data in the memory card can be played by transferring it to the mobile device. There are many kinds of cameras, waterproof digital cameras and video cameras, and their basic principles are the same: converting optical image signals into electrical signals for storage or transmission. When we shoot an object, the light reflected by the object is collected by the camera lens and focused on the light receiving surface of the camera device (such as the target surface of the camera tube), and then the light is converted into electric energy by the camera device, and a "video signal" is obtained. The photoelectric signal is very weak, so it needs to be amplified by pre-amplifier circuit and then processed and adjusted by various circuits. The final standard signal can be sent to video recorders and other recording media for recording, or spread through a propagation system, or sent to a monitor for display. [ 1]

Traditional camera signals are pushed to the Tik Tok platform. The first way is that the camera is connected to the NDI encoder through SDI/HDMI and pushed to Tik Tok live companion, and then the NDI encoder is connected to the switch network, and the computer is also connected to the same subnet. When the network has DHCP function, N30 devices will automatically obtain IP.

Under the same subnet, the NDI stream after NDI encoder can be found by other NDI devices. The specific equipment connection is shown in the figure below.

Install NDItools (which can be downloaded from NewTek official website) on the computer, and then open the NDIVirtualInput program in the NDItools folder, which will be displayed in the toolbar at the lower right corner of the computer. Right-click to select the NDI device and channel to receive.

Open the APP, see more wonderful pictures, enter Tik Tok official website, download and install Tik Tok Live Companion. Install Tik Tok life partner on the computer and log in to life partner. In Add Material-Capture-Set Material, select NewTekNDIVideo from the drop-down video capture signal list, and the live broadcast partner will receive NDI video forwarded by VirtualInput.

Since this year, slow live broadcast has become popular as a new form of live broadcast. CCTV and major local media have continuously introduced various slow live programs, such as Wuhan Volcano Mountain, the construction of Thunder God Mountain hospital, the annular eclipse in 2020, and the launch of Beidou-3 satellite. Bring people a brand-new program viewing experience. The so-called slow live broadcast refers to a form of live broadcast in which real scenes are recorded in real time for a long time with the help of live broadcast equipment and presented in the original ecology. There is no host, no subtitles, no gorgeous lens switching and exquisite post-production, and only fixed-position shooting is used to show the scene of the event more truly, so that the viewer's sense of participation and immersive experience are more real. The development of slow live broadcast is about to enter the next normal development stage, attracting specific audiences with the characteristics of low production cost and "no added" real reports. Most of the existing video monitoring projects belong to local area network monitoring, and the network video stream cannot be directly transmitted to the Internet live broadcast platform.

Electronic MG300 video gateway can quickly and conveniently convert RTSP video streams from multiple surveillance cameras into RTMP real-time streams for slow Internet live broadcast. There is no need to change the location and line of the original surveillance camera, and the MG300 video gateway can access the same network and public network of the surveillance camera.

How to broadcast live with a camera

The camera is connected to the live broadcast. First, you should connect the SDI or HDMI signal of the camera to the live video streaming box, then register a third-party live broadcast platform, or build a live broadcast platform yourself, so that the streaming media address of the live broadcast platform can be copied to the encoder background. Live camera broadcast can be realized.

How to connect the camera to the computer to realize real-time live broadcast?

If it's a digital video camera (which is usually the case now), connect the computer with a data cable, install the driver, and then open the live broadcast software to use it directly.
