Commonly used streaming media protocols mainly include HTTP progressive download and real-time streaming media protocol based on RTSP/RTP, which are basically completely different things. At present, HTTP progressive download mode is more convenient and easy to use. Apple's Httpplivestream is a representative of this.

Question 5: What's the difference between 5:RTMP, RTSP and HLS? Dynamic rate adaptation technology of apple. Mainly used for audio and video services of PC and Apple terminals.

RTMPAdobe's streaming media transmission protocol, port number 1935, can be used by ordinary network users, including users on non-IOS platform and users in network environment not limited to 80 ports (such as 1935). Advantages: HTTP download is prevented and the delay is short.

RTSP and RTMP are two different network transmission protocols, RTSP(RealTimeStreamingProtocol) and RFC2326. RTMP is a manufacturer of network cameras, and can adopt different protocols according to their own needs.

Generally speaking, according to different needs, prices are different, and they are all known in person. Prepare for the demand and budget. The next step is to find a professional app production platform and make an exclusive app.

What are the protocols for webcasting?

ARP protocol analysis will be used to watch the live football match on the Internet. ARP(AddressResolutionProtocol) is used to convert a computer's network address (IP address 32 bits) into a physical address (MAC address 48 bits) [RFC826].

The commonly used transport protocols RTMP, HLS, HTTP-FLV, HLS and HTTP-FLV are all based on HTTP, while RTMP is based on TCP. HLS, namely HttpLiveStreaming, is a streaming media transmission protocol based on HTTP proposed by Apple.

The live broadcast belongs to the live broadcast contract signed by the broadcaster and the live broadcast company on the live broadcast platform, so it belongs to the labor contract. When an anchor signs a contract with a company, it can constitute a labor relationship or an entrustment relationship. It is necessary to judge whether it constitutes a labor relationship according to factors such as whether it accepts superior management, salary calculation method and whether it is paid monthly.

The abbreviation of RTMP (Real-time Messaging Protocol) is a protocol developed by AdobeSystems, which is used for audio, video and data transmission between Flash players and servers.

At present, the stream address is a fixed RTMP protocol, and each live broadcast room has a corresponding stream address. For more service offers, click "official website" below.

What's the difference between video codecs?

The difference between a network video encoder and a network video decoder lies in different functions, different converted signals and different characteristics. Network video encoders with different functions: provide video compression function and complete image data acquisition. Network video decoder: provides video decompression function and completes the restoration of image data.

Video encoder: It is a compression program. Video decoder: It is a decompression program. Video codec requires high and stable real-time transmission, so it is best to choose professional factory direct sales and professional R&D team technology. To have high compatibility, various types of network video coding and decoding.

There are three main differences: hardware decoding is hardware decoding of video, in which hardware decoding is carried out by GPU, which can reduce the workload and power consumption of CPU; Software decoding is decoding through the CPU occupied by the software itself, so it will increase the workload of CPU and increase power consumption.

At present, H.264 is more in line with the standard of high compression digital video coding and decoding. The advantages of high-definition video codec are ultra-low delay (generally up to 40ms), high compression ratio (supporting 300K-40Mbps dynamic stream coding), high-definition image quality and high frame rate (1080p/60 frames).

It supports 7×24 hours operation, dual output of HDMI and VGA, and can decode mainstream streaming media protocols, such as RTMP, RtsP, UDP, TSOVERHTTP, TS and other live broadcast protocols. Support 1080P hardware real-time decoding, and support Web mode operation control. More recommended principles for video decoder solutions.

Video codec refers to a program or device that can compress or decompress digital video. The process of compressing and possibly changing the format of video content, changing an analog source to a digital source. Both audio and video require customizable compression methods. In terms of compression, the goal is to reduce the occupied space.

What are the uses and differences of RTP, RTCP, RTSP and other network protocols?

1 and RTP (real-time transport protocol) are the transport protocols of multimedia data streams on the Internet. RTP is defined as working in the case of one-to-one or one-to-many transmission. Its purpose is to provide time information and realize stream synchronization. But RTP usually uses UDP to transmit data.

2.TCP protocol is a typical connection protocol, while UDP protocol is a typical connectionless service. TCP/IP protocol includes protocols and tools. TCP/IP protocol is a set of network protocols, which mainly includes the following protocols and tools.

3.RTP generally cooperates with RTCP, which is only responsible for real-time data transmission, and RTCP is responsible for the out-of-band management of RTP communication and session (such as traffic control, congestion control, session source management, etc.). ). RTP uses even port numbers, while the corresponding RTCP stream uses the next (odd, increasing) port number.

4. Network cameras often use different combinations of RTSP, RTP, RTCP, HTTP, UDP and TCP protocols to transmit real-time audio and video streams. Common protocol combinations are as follows.

What is the RTMP live broadcast protocol? What other live broadcast protocols are there?

The abbreviation of RTMP (Real-time Messaging Protocol) is a protocol developed by AdobeSystems, which is used for audio, video and data transmission between Flash players and servers.

RTMP: (can be used for push and pull) Real-time message protocol Real-time message transmission protocol. In RTMP protocol, video must be encoded in H264, audio must be encoded in AAC or MP3, and most of them are packaged in flv format.

There are three P live broadcast protocols: RTMP, FLV and HLS.

Commonly used streaming media protocols mainly include HTTP progressive download and real-time streaming media protocol based on RTSP/RTP, which are basically completely different things. At present, HTTP progressive download mode is more convenient and easy to use. Apple's Httpplivestream is a representative of this.

HTTP-FLV is a protocol that simulates live streaming into FLV files and downloads them through http protocol to realize streaming media transmission. RTMP, namely RealTimeMessagingProtocol, is an open protocol developed by AdobeSystems, which is used for audio, video and data transmission between Flash players and servers.

RTSP and RTMP are two different network transmission protocols, RTSP(RealTimeStreamingProtocol) and RFC2326. RTMP is a manufacturer of network cameras, and can adopt different protocols according to their own needs.

HLS clients are easy to support, and only need HTTP requests. HTTP is stateless, just download the media clips in order. In addition, the network compatibility is good, and HTTP messages can easily pass through firewalls or proxy servers. However, compared with RTMP, interactive real-time broadcast scenarios have higher delay.
