Record: 1, looked for two websites: http://ffdshow-tryout.sourceforge.net/wiki/devel:building this, is k-lite http://ffmpeg.zeranoe.com/builds/ this, is Windows Platform compiled FFMPEG. This is the key to carefully reading the second web page. Download the latest library and code. T

above 6-point Interactive Protocol, it can support flash playback, smooth output of the video stream of H.Design and implementationKnowing the interaction process, we can design and implement our own RTMP server. Because the RTMP protocol is based on the TCP protocol, RTMP server is essentially a TCP server, and its logical structure is basically similar to the normal TCP server.In fact, LIBRTMP has provided the basic RTMP message read and send, can be developed on the basis of librtmp, to achi

Recently, many people asked me where to set SPS and PPS. In fact, this article is just a simple implementation of my previous article. For more information, see the previous article.

If the power of a person is limited, the power of the network is infinite. The purpose of studying h264 is to customize a streaming media player to play videos in real time. Fortunately, there are a lot of online cool people standing on the shoulders of giants, and the pressure will be much lower. Overall Player Design Scheme Generally, the overall player design includes three stages:1) obtain media data2) decoding Audio and Video Streaming Media3) di

H.264 is the latest format defined by the MPEG-4 standard, and is also one of the most technically available video coding formats, representing the latest technology, some of which are also called AVC. Use software mediacoder can convert video into H264 video format, it is a free software, you can go to Baidu search to download first. Start MediaCoder, the main interface as shown in the following figure, please click the "+" in the upper left corner

Using FFmpeg to decode H264 data is actually a lot simpler than using x264 for video encoding, because FFmpeg provides a decoding_encoding.c file with a simple example of using FFmpeg for video, audio codec, But maybe some people will not find this example, I will say I have modified the example put here, and add some explanations. One of the t

Requirement: The Android side puts a video stream that is playing on the webcam and intercepts it to save it as a MP4 (the recording is started when the video button is pressed). Implementation: FFmpeg + x264 + sdl; H264 Bare stream Packaging into MP4, there are a lot of articles on the Internet, FFmpeg also has a muxing example, the general process is the same, referring to FFmpeg muxing.c can write one. I am here to write about the problems I encoun

The following figure is the data in Packet.data As you can see from the diagram, there is no delimiter (0x00000001) at the beginning of the data in packet, nor is it 0x65, 0x67, 0x68, 0x41, and so on, so it is certain that this is not a standard Nalu. In fact, the first 4 charact

(There is no time to study whether I, P, b frame is really in H. C and MPEG, first turn around) 1, the basic flow of I, P, B frame coding in H264 The basic process for I-frame encoding is:(1) The intra-frame prediction model is used to determine the intra-frame prediction mode.(2) The pixel value minus the predicted value, resulting in a residual error.(3) to transform and quantify the residual error.(4) Variable length coding and arithmet

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

When using RTP to transmit H264 data, when the length of the Nalu is too long to subcontract, here is an example, if you want to know more detailed protocol description can refer to the end of the connection.
