Transplant mplayer player under linux

Preparation

To compile the mplayer player, you need to download the source code first

zlib library source code http://zlib.net/  choose the latest version here

Then download the mplayer source code

mplayer source code http://www.mplayerhq.hu/MPlayer/releases/I choose version 1.2 here

 Another point is that because my board is a 32-bit linux system, I also chose a 32-bit image for the virtual machine environment. If I choose a 64-bit image, I may need to install some 32-bit libraries when compiling.

Ubuntu 16.04.7 LTS (Xenial Xerus) https://releases.ubuntu.com/16.04/

Finally, the choice of the cross compiler is the latest version of the decompressed version of arm-none-linux-gnueabi-gcc

[ARM-Linux development] arm-none-Linux-gnueabi-gcc download and install - ZhangPYi - Blog Park (cnblogs.com) https://www.cnblogs.com/huty/p/8517621.html will not be installed in a virtual machine You can refer to this article of mine

Ubuntu installs cross compiler arm-linux-gcc_yuansec's blog - CSDN blog https://blog.csdn.net/lhh2333/article/details/128203656?spm=1001.2014.3001.5501

zlib compile

First put the source code into the virtual machine, unzip it in any folder, and then create a folder zlib on the desktop to store the compiled library files

Go to the unzipped source code folder and cut it first

./configure --prefix=/home/lhh/桌面/zlib --shared --static

--prefix: Indicates the generated file storage path

After cutting, a makfile will be generated, open the mkfile, and change the compiler to arm-none-linux-gnueabi-gcc 

then execute

make
make install

The file we want will be generated in the previously created zlib file.

mplayer compile

Open the decompressed mplayer source file

Also crop first

./configure --cc=arm-none-linux-gnueabi-gcc --ar=arm-none-linux-gnueabi-ar --ranlib=arm-none-linux-gnueabi-ranlib --disable-gui --target=arm-none-linux-gnueabi  --host-cc=gcc --extra-cflags="-I/home/lhh/桌面/zlib/include" --extra-ldflags="-L/home/lhh/桌面/zlib/lib -Iz" --enable-fbdev --disable-mencoder

--extra-cflags: Linked files (ie just compiled zlib files)

directly after no problem

make -j4

Four threads compile together

Finally, an mplayer file will be generated in the current directory

actual effect

Finally, put the generated mplayer file into the development board/bin directory

Then you can play the video, I won’t talk about mplayer commands, there are a lot of them on the Internet
