Windows Media Encoder Streaming Media Production Application

Windows Media Encoder Streaming Media Production Application

Windows Media Encoder is a powerful streaming media production tool used to convert live or pre-recorded video and audio files into Windows Media files and streams. With the perfect combination of the acquisition card and encoder, you can easily compress live videos and audio source signals into files or streams in WMV format in real time. Next we will study the application of Windows Media Encoder. To achieve this operation, you need a PC with a slightly better configuration (Inter P4 CPU) and a professional streaming media acquisition card, which is mainly used for front-end video and audio collection, here we promote the Guangzhou video profit (http://www.webviews.com.cn) svc400 acquisition card widely used in the industry, it is a cost-effective, high definition, stable quality of streaming media Video Acquisition Card. This product mainly targets streaming media fields and adopts a general DirectShow driver architecture with efficient video and sound collection capabilities. High-performance analog video front-end filtering and high-precision audio sampling capabilities greatly improve the definition of video/audio acquisition. Svc400 can be used with helix real producer of Windows Media Encoder and RealNetwork to make courseware on demand, live TV broadcast, remote monitoring, video conferencing, etc. Now let's have a try on the site: 1. First, install the svc400 Device Driver correctly and check whether the installation is successful. You can see it in the Device Manager, as shown in-"webviews capture device !! Indicates that the device is correctly installed. 2. Run Media Encoder. The following window is displayed. Select broadcast live events and press OK ": 3. A new window is displayed, such. Select the video and audio devices corresponding to svc400 in the video and audio options. Click "configuration" corresponding to the video device, select the corresponding Video Input Source in the Properties window, and press OK; 4. Press "Next" to bring up the following window. Select "self-Encoding Transfer" and press "Next "; 5. In the following dialog box, let the user select the port used to pull the pair. We can directly select the default port 8080 (of course, this port is available only when it is not occupied by other programs ), click "Next "; 6. Select the bit rate and frame rate to encode the output. Of course, we can simply end the initial configuration of the Encoder by following "complete" and leave it on the "properties" page later; 7. The initial configuration is complete. We can see the image !! 8. At this time, we can set attributes such as the compressed bit rate and Frame Rate on the attribute page, for example; 9. You can also edit the selected bit rate and frame rate options, as shown in. Click "edit; 10. parameters such as audio, video size, frame rate, and video bit rate can be set in the following dialog box, which is simple and convenient; 11. The device output attributes are shown below. There are three output modes: Push transfer, pull transfer, and archive. Among them, "Push transmission" should be used together with another set of Microsoft's streaming media publishing tool "Media Service". If you are interested in research, you can pay attention to our next article on push transmission, here we do not select. 12. Everything is ready. Press it to start compression. Now we can use media player to receive live video and audio streams. Enter the following in the address box: You can receive clear and smooth live video !! All computers in the same LAN can directly use media player to receive live signals from the address and port number. In just a few minutes, we have built a simple and practical network-based live video broadcast system !!
