Use Nginx + FFmpeg to build an HLS live video transcoding Server
Objective: To enable Nginx to support Rtmp streaming, HLS distribution, and FFmpeg transcoding multi-bit rate.
I. PreparationsModule: nginx-rtmp-module-master (rtmp protocol supported):Http://nginx.orgHttps://github.com/arut/nginx-rtmp-module
1. Install the dependency package:# Yum-y install gcc glibc-devel make nasm pkgconfig lib-devel openss
Use a variety of streaming playlists instead of a single stream of code. The HLS client can dynamically change the stream based on the bandwidth situation, providing the user with the best user experience. (This argument is more idealized, personally think that as long as you can provide a variety of code flow to the user to choose, the app in the start video, according to the bandwidth to select the use of the stream) need to consider the following i
mode represented by the principle of the three colors is called the CMYK mode, which is widely used in painting and printing.
RGB mode is the most commonly used color mode for drawing software. In this mode, it is easier to process images, and the RGB storage images are smaller than those of CMYK images, memory and space can be saved.
CMYK mode is a pigment mode, so it belongs to the printing mode, but it is essentially no different from the RGB mode, but it only produces different colors. RGB
Mobile HTML5 supports HLS format for video playback, creating a new file named Videoplayerdemo-html5.html OpenThe file is written as follows, and the file is saved to the mobile side (for example, the Android phone) and opened to watch the video,As shown in 1."utf-8"> "352" height= " 288" controls> "http://live.hkstv.hk.lxdns.com/live /hks/playlist.m3u8 "type="application/vnd.apple.mpegurl"> The Browser does not support video tags.

1. There are two novel vbs Downloaders on this blog. One is made of the CDO. Message component and the other is made of Microsoft. XMLDOM. For details, see http://www.jb51.net/article/15506.htm. One of the two Downloaders is difficult to use and needs to convert the exe file in advance. Second, cscript.exe accesses the network, which is not concealed. Second, some machines do not have these two components and use them to ADODB. Stream, so there are some drawbacks.

Usually a frame of data is a PES package. A PES package can typically be split into multiple TS packages (it is also possible to split into only one TS package, that is, the PES package is less than 188 bytes in length).

necessary for all developers. In order to teach the correct annotation technique, I often add comment code in my own demo program. Also, to simplify the annotation process, I recommend that developers first write comments explaining the programs they want to write. I will first write the procedure, class, or other program elements in the program, but do not elaborate on its specific workings. Then I'll write a series of comment codes that describe each of the main steps of the process or the el
