1.安装编译x265所需环境
1
| sudo apt-get install mercurial cmake cmake-curses-gui build-essential yasm
|
2.下载x265源码并编译

| hg clone https://bitbucket.org/multicoreware/x265
cd x265
hg co 1.2
cd build/linux
./make-Makefiles.bash
make
sudo make install
|
注 这里只能使用1.2的版本,1.3和最新的都会在编译ffmpeg时出问题
如果运行x265出现如下错误,在/lib下添加对应的软链接即可.
1
2
| $ x265
x265: error while loading shared libraries: libx265.so.25: cannot open shared object file: No such file or directory

| cd /lib
sudo ln -s /usr/local/lib/libx265.so.25
cd -
|
后面如果遇到同样问题,解决方法相同,so从那里得知呢? 仔细看make install的打印信息就知道了.
3. 安装ffmpeg编译所需库
—enable-libvidstab 依赖

| git clone https://github.com/georgmartius/vid.stab.git
cd vid.stab
cmake .
make
sudo make install

| git clone https://github.com/dekkers/libilbc.git
cd libilbc
mkdir build
cd build
cmake ../

其他的从系统库中安装即可

make
sudo make install

6.查看hevc编码器是否存在
1
| ffmpeg -codecs | grep -i hevc
|
看到如下信息表示hevc/x265编码已经安装成功
1
| DEV.L. hevc H.265 / HEVC (High Efficiency Video Coding) (encoders: libx265 )
|
在编码器最前面有一串字符串,含义如下
1

| Codecs:
D..... = Decoding supported
.E.... = Encoding supported
..V... = Video codec
..A... = Audio codec
..S... = Subtitle codec
...I.. = Intra frame-only codec
....L. = Lossy compression
.....S = Lossless compression
