WebRTC represents the best technology in the field of real-time communication since the date of birth. But for a long time, it supported the video encoder only VP8, and later with H265/VP9 as the representative of the birth of the next generation of video Encoders, WebRTC appeared VP9 Codec. The most widely used H264 has been kept out of sight. Until Cisco announces its H264 codec open source for OpenH264,
Recently experiment how to let WEBRTC support H264 code, record, for people who need reference.To illustrate, I was compiling the WebRTC under Ubuntu Server 14.04, using the native (c + +) API to develop WebRTC applications. So my adjustments are based on the native code.The end result is that the browser can send a video with H264 or receive H264 video.Note that

The recent need to encode H264 video into MP4 format. Research, one method is to use the FFmpeg library, you can first decode the H264 file, and then encode the generation of MP4 files, but this method is less efficient, 10M video may take a few seconds to complete. Another way is to encapsulate the H264 package directly into the MP4 format according to the MP4 f

After installing the FFmpeg, if you use the FFmpeg tool to turn a video file into H264 video encoding, MP3 audio encoding or other ffmpeg itself without the XXX encoding type, you will see the error message, unknown encoder ' xxx '. Now all you need is to install the other encoder on the line, essentially the other encoder in the form of a library installation, for example, t

The former is responsible for effectively representing the content of the video data, while the latter is responsible for formatting the data and providing the header information to ensure that the data suitable f
After reading the introduction of H264/AVC codec, I just left the following three articles in my mind:1, H264 does not understand how to implement a codec, just a coded video bit stream syntax, and the Bitstream decoding method, this is similar to MPEG.2, H264 and once the standard (such as H261, H263, MPEG-1, MPEG-4) codec implementation process is not much diff
The previous article described "H264 video via rtmp stream live", below will explain how to H264 live video live through RTSP.
The realization of the idea is to send the video stream to live555, by live555 to achieve the H264 data stream live.
The video capture module sends the H264 data frame to live555 through a FIFO
What is h264 video file format?
H.264 is the latest format defined by the MPEG-4 standard, and it is also one of the most technically available video coding formats, representing the latest technology, some also called AVC (Advanced Video coding), a video compression standard. is a widely used format for recording, compressing, and publishing high precision video.

During this period of time, the work needs are converted from FLV stream to standard h264 and aac on rtmp. The server is an open-source project crtmpserver, client flex writing, video encoding h264, and audio encoding AAC, some protocol-related items are recorded as follows.
1. Analyze FLV data
Let's take a FLV file to analyze the FLV data format.

Preface
Some time ago, we have been engaged in video coding and decoding and transmission. Now, basically the whole system can implement the function of real-time server encoding packaging and transmission to the client, and the client can be decoded and displayed in real time, so I will record the work in the previous stage and use x264 for H. 264 the process of encoding, the process of transmitting
This time, the work of the need, on the rtmp to do the FLV stream to the standard H264, AAC conversion, the server is open source project Crtmpserver, client flex writing, Video coding H264, Audio coding AAC, now some of the agreements related to the following things record.
