centos7下視訊解碼播放環境搭建(ffmpeg等庫編譯)
1.軟體環境
作業系統環境:centos7
ffmpeg原始碼: github上的master版本(當前官網的3.4.1版本有bug,在主幹中修復了'x264_bit_depth' undeclared)
2.編譯與安裝
設定環境變數:(可以在/root/.bashrc指令碼中設定,重啟有效)
export PATH="$PATH:/usr/local/bin:/usr/local/yasm/bin:/usr/local/SDL/bin:/usr/local/x264/bin"
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
export C_INCLUDE_PATH="$C_INCLUDE_PATH:/usr/local/SDL/include/SDL:/usr/local/x264/include"
export LD_LIBRARY_PATH="/usr/local/lib
2.1 yasm安裝
./configure --prefix=/usr/local/yasm
make
make install
2.2 SDL安裝
./configure --prefix=/usr/local/SDL
make
make install
2.3 x264安裝
./configure --enable-shared --disable-asm --prefix=/usr/local/x264
make
make install
2.4 ffmpeg安裝
./configure --enable-shared --disable-static --enable-libx264 --enable-gpl --prefix=/usr/local/ffmpeg-master
make
make install
3.安裝好的庫lib和標頭檔案路徑include
/usr/local/yasm
/usr/local/x264
/usr/local/SDL
/usr/local/ffmpeg-master
4. 補充.幾個解碼庫路徑:
