Compile FFmpeg on Ubuntu

This guide supports Ubuntu Precise Pangolin 12.04, Ubuntu Oneiric Ocelot 11.10, Ubuntu Natty Narwhal 11.04, and Ubuntu Maverick Meerkat 10.10. Separate guides are available for Ubuntu Lucid Lynx 10.04 and Ubuntu Hardy Heron 8.04. This guide will enable several external encoding and decoding libraries: libfaac (AAC encoder), libfdk-aac (AAC encoder), libmp3lame (MP3 encoder), libopencore-amr (AMR encoder/decoder), librtmp (for additional RTMP protocols), libtheora (Theora encoder), libvorbis (Vorbis encoder), libvpx (VP8 encoder/decoder), and libx264 (H.264 encoder). These are optional and may be omitted if desired. This guide will also install many filters (see the filter list in the [Filtering Guide](https://ffmpeg.org/trac/ffmpeg/wiki/Fi

FFmpeg Minimal Build for RTMP Streaming

This tutorial will work you through steps of configuring an FFmpeg build tailored for RTMP streaming on macOS. At first I think of making it support general live streaming, with additional protocols like HLS, but to keep things simple let's stick with RTMP for now. (Anyway, I do include HLS in the protocol list as well as some related bitstream filters but it's untested.)

Goal

The built FFmpeg executable should

使用ffmpeg合并MP4文件

ffmpeg -i "Apache Sqoop Tutorial Part 1.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
ffmpeg -i "Apache Sqoop Tutorial Part 2.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
ffmpeg -i "Apache Sqoop Tutorial Part 3.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate3.ts
ffmpeg -i "Apache Sqoop Tutorial Part 4.mp4" -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate4.ts
ffmpeg -i "concat:intermediate1.ts|intermediate2.ts|intermediate3.ts|intermediate4.ts" -c copy -bsf:a aac_adtstoasc "Apache Sqoop Tutorial.mp4"

Nice answer on stackoverflow to the question of when to use one or the other content-types for POSTing data, viz. application/x-www-form-urlencoded and multipart/form-data.

“The moral of the story is, if you have binary (non-alphanumeric) data (or a significantly sized payload) to transmit, use multipart/form-data. Otherwise, use application/x-www-form-urlencoded.”

Matt Bridges' answer in full:

The MIME types you mention are the two Content-Type headers for HTTP POST requests that user-agents (browsers) must support. The purpose of both of those types of requests is to send a list of name/value pairs to the server. Depending on the type and amount of data being transmitted, one of the methods will be more efficient than the other. To understand why, you have to look at what each is doing



	# GLiNet MT300N-V2 安装 SSR plus 插件


	GLiNet 是一家生产便携路由的国内厂商好像外销为主。
	最主要的是他家路由系统采用的是开源 OpenWrt 系统并在github 上开源并提供sdk 和很多插件
	但是国内政策的关系国内买到的路由器固件内并没有提供直接安装 SS SSR V2ray 的方法。

	经过在恩三论坛学习了下（www.right.com.cn）已经成功把lean 开源的(https://github.com/coolsnowwolf/lede.git) SSR plus 插件成功的安装到了 MT300N-V2 固件中，下面记录一些安装步骤。

	第一步，在/etc/yum.repos.d/目录下创建一个源配置文件nginx.repo：

	cd /etc/yum.repos.d/

	vim nginx.repo

	填写如下内容：

	[nginx]
	name=nginx repo

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console
