What are the encoders used in the development of video chat software?

During the development of one-to-one video chat software, numerous audio and video encoding and decoding technologies are involved, such as video encoding and decoding, audio encoding and decoding, hardware encoding and decoding, and audio and video encryption. To realize these technologies, you must choose a suitable encoder. The encoder has undergone decades of development. From the beginning it only supports intra-frame encoding and has evolved to a new generation of encoders represented by H.265 and VP9. Let’s take a look at the development of one-to-one video chat software. What are the frequently used encoders? One-to-one video chat software development.

1. H.264 H.264 intends to create a video standard. Compared with old standards such as MPEG-2, H.263 or MPEG-4, it can provide high-quality video at a lower bandwidth without adding too much design complexity to make it impossible to achieve or the cost of implementation is too high. The purpose is to provide enough flexibility to be used in various applications, networks and systems, especially for one-to-one video chat software, which requires high bandwidth and resolution live broadcast platforms, which will bring Many advantages. The new features in H.264 enable it to not only encode more effectively than previous codecs, but also to be used in applications in various network environments. This technical foundation allows major live broadcast platforms to adopt it as a As the main encoder. However, using it is not an easy task-the patent fee is relatively high. One-to-one video chat software development.

2. HEVC/H.265 H.265, also known as High Efficiency Video Coding (HEVC for short), is regarded as the successor to H.264. HEVC can not only improve the video quality by several grades, but also achieve twice the compression rate of H.264/MPEG-4. , This is equivalent to a 50% reduction in the bit rate under the same picture quality, which can support 4K resolution or even ultra-high resolution, and the highest resolution can reach 8 times. This is more than enough for one-to-one video chat software.

3. VP8 VP8 is an open video compression format that was first developed by On2 Technologies and then released by Google. At the same time, Google also released the VP8 coded implementation library: libvpx, which was issued in the form of BSD license terms, and subsequently added the right to use the patent. After some arguments, the authorization of VP8 was finally confirmed as an open source authorization. VP8 can provide higher-quality videos with less data, and can play videos with less processing power. Currently, the web browsers that support VP8 include Opera, Firefox, and Chrome. It can be said that the limitations are large, which is a shortcoming.

4. VP9 VP9 is an upgraded version of VP8. Under the same image quality, it reduces the file size by 50% compared to VP8 encoding. The encoding efficiency is the same as H.265 (HEVC). Its biggest advantage is that it has no royalties and can be used for free. And it supports more browsers. One-to-one video chat software development.

5. FFmeg FFmeg is a free software that can run recording, conversion, and streaming functions in multiple formats of audio and video. It is most commonly used in the video capture function. Of course, the coding function is equally powerful (it can encode and decode in real time). In addition to the advantages of the above decoders, it has strong compatibility. This is currently other encoders. Unattainable. The above is the commonly used encoder in one-to-one video chat software. In fact, it is not only live broadcast, as long as it is a video platform, you can access the above video encoders. That's it for today's introduction.

How far(long) the transmitter cover? The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far. EXAMPLE 5W FM Transmitter use in the city and hometown: I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile). I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile). I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft). Below are the approximate range of different power FM Transmitters. ( The range is diameter ) 0.1W ~ 5W FM Transmitter ：100M ~1KM 5W ~15W FM Ttransmitter : 1KM ~ 3KM 15W ~ 80W FM Transmitter : 3KM ~10KM 80W ~500W FM Transmitter : 10KM ~30KM 500W ~1000W FM Transmitter : 30KM ~ 50KM 1KW ~ 2KW FM Transmitter : 50KM ~100KM 2KW ~5KW FM Transmitter : 100KM ~150KM 5KW ~10KW FM Transmitter : 150KM ~200KM How to contact us for the transmitter?
