3、将ffmpeg套件的ffmpeg新版程序替换VideoStation套件中的对应旧版程序

cd /var/packages/VideoStation/target/bin
mv ffmpeg ffmpeg.orig
mv ffprobe ffprobe.orig
mv vainfo vainfo.orig
cp -a /var/packages/ffmpeg/target/bin/ffmpeg /var/packages/VideoStation/target/bin/
cp -a /var/packages/ffmpeg/target/bin/ffprobe /var/packages/VideoStation/target/bin/
cp -a /var/packages/ffmpeg/target/bin/vainfo /var/packages/VideoStation/target/bin/
chown root:VideoStation /var/packages/VideoStation/target/bin/ffmpeg
chmod 750 /var/packages/VideoStation/target/bin/ffmpeg
chmod u+s /var/packages/VideoStation/target/bin/ffmpeg
chown VideoStation:VideoStation /var/packages/VideoStation/target/bin/ffprobe
chown VideoStation:VideoStation /var/packages/VideoStation/target/bin/vainfo

4、修改类库，添加dts支持

cp -an /var/packages/VideoStation/target/lib/libsynovte.so /var/packages/VideoStation/target/lib/libsynovte.so.orig

\# Patch libsynovte.so to authorize DTS, EAC3 and TrueHD

sed -i -e 's/eac3/3cae/' -e 's/dts/std/' -e 's/truehd/dheurt/' /var/packages/VideoStation/target/lib/libsynovte.so
