This article introduces the relevant knowledge of "the detailed steps of installing ffmpeg in linux". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

#! / bin/bash

# Bash script to install latest version of ffmpeg and its dependencies on Ubuntu 12.04 or 14.04

# Inspired from https://gist.github.com/faleev/3435377

# Remove any existing packages:

Sudo apt-get-y remove ffmpeg x264 libav-tools libvpx-dev libx264-dev

# Get the dependencies (Ubuntu Server or headless users):

Sudo apt-get update

Sudo apt-get-y install build-essential checkinstall git libfaac-dev libgpac-dev\

Libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev librtmp-dev libtheora-dev\

Libvorbis-dev pkg-config texi2html yasm zlib1g-dev

# Install x264

Sudo apt-get-y install libx264-dev

Cd

Git clone-depth 1 git://git.videolan.org/x264

Cd x264

. / configure-- enable-static

Make

Sudo checkinstall-- pkgname=x264-- pkgversion= "3 version.sh $(. / version.sh |\

Awk-F'["]'/ POINT/ {print $4" + git "$5}')"-- backup=no-- deldoc=yes\

-fstrans=no-default

# Install AAC audio decoder

Cd

Wget http://downloads.sourceforge.net/opencore-amr/fdk-aac-0.1.0.tar.gz

Tar xzvf fdk-aac-0.1.0.tar.gz

Cd fdk-aac-0.1.0

. / configure

Make

Sudo checkinstall-- pkgname=fdk-aac-- pkgversion= "0.1.0"-- backup=no\

-deldoc=yes-fstrans=no-default

# Install VP8 video encoder and decoder.

Cd

Git clone-depth 1 https://chromium.googlesource.com/webm/libvpx

Cd libvpx

. / configure

Make

Sudo checkinstall-- pkgname=libvpx-- pkgversion= "1 date $(date +% Y%m%d%H%M)-git"-- backup=no\

-deldoc=yes-fstrans=no-default

# Add lavf support to x264

# This allows x264 to accept just about any input that FFmpeg can handle and is useful if you want to use x264 directly. See a more detailed explanation of what this means.

Cd ~ / x264

Make distclean

. / configure-- enable-static

Make

Sudo checkinstall-- pkgname=x264-- pkgversion= "3 version.sh $(. / version.sh |\

# downloaded rtmpdump

Http://rtmpdump.mplayerhq.hu/

Git clone git://git.ffmpeg.org/rtmpdump

Cd rtmpdump

In order to get debugging information, simply modify the Makefile file of folder rtmpdump and librtmp, add the-g parameter, and pay attention to removing the optimized parameter-O2

In the Makefile of rtmpdump

OPT=-O2

CFLAGS=-Wall-g $(XCFLAGS) $(INC) $(DEF) $(OPT)

In the Makefile of librtmp

CFLAGS=-Wall.... -g

two。 Install related dependent classes

The dependent libraries that need to be used are zlib and openssl libraries, which can be installed using the following command

Sudo apt-get install openssl

Sudo apt-get install libssl-dev

Sudo apt-get install zlib1g-dev

You can check the available installation packages first

Sudo apt-cache search openssl

By reading the Makefile file, I found that the dynamic libraries that rtmpdump needs to reference are as follows

-lz-lssl-lcrypto-lrtmp-lpthread

After make, 4 executable files are generated, which are rtmpdump,rtmpsvr, rtmpsuck and rtmpgw, in which pthread is directly used in rtmpsvr, rtmpsuck and rtmpgw programs.

3. Compilation and installation

Make

Sudo make install

First of all, make sure that the relevant libraries have been successfully installed under / usr/local/lib

Make sure / usr/local/lib is in the / etc/ld.so.conf configuration file again, and then

Sudo ldconfig

To update the dynamic library cache

Check whether all dependent libraries of rtmpdump are referenced successfully

Ldd rtmpdump

# downloaded libogg

Wget https://downloads.xiph.org/releases/ogg/libogg-1.3.2.tar.xz

Installation of libogg

Install libogg by running the following commands:

# Optional: install qt-faststart

# This is a useful tool if you're showing your H.264 in MP4 videos on the web. It relocates some data in the video to allow playback to begin before the file is completely downloaded. Usage: qt-faststart input.mp4 output.mp4.

I tested it with a transcode.

# ffmpeg-I file.avi output.flv

Found a mistake that could not be found in the library.

Went to search for related questions.

So I just...

After a soft link, the test passed again.
