我从这里获得了 acestream_3.0.3_centos_7_amd64的直接镜头，请参阅此线程，然后我尝试了：

我还从这里获得了acestream-engine的目录，然后我附加了" post_install"，并将其附加到此文件acestream-engine.install：
post_install() {
if ! getent passwd acestream &> /dev/null; then
useradd -u 4035 -g video -m -s /usr/bin/nologin acestream
fi
}
post_upgrade() {
post_install
}
post_remove() {
if getent passwd acestream &>/dev/null; then
userdel acestream
fi
}
post_install
，为了运行acestream-engine服务（请参阅此线程）：
[xiaobai@xiaobai acestream-engine]$ systemctl start acestream-engine.service
Failed to start acestream-engine.service: Unit acestream-engine.service failed to load: No such file or directory.
[xiaobai@xiaobai acestream-engine]$ sh acestream-engine.install

[xiaobai@xiaobai acestream-engine]$ sudo cp acestream-engine.service /lib/systemd/system/
[xiaobai@xiaobai acestream-engine]$ sudo systemctl start acestream-engine.service
i还请参考文件PKGBUILD（此文件仅存在于AceStream_3.0.5.1_ubuntu_14.04_x86_64中，但实际上是Acestream_3.0.3_centos_7_amd64可以使用）并手动运行命令：
[xiaobai@xiaobai acestream_3.0.3_centos_7_amd64]$ sudo install -Dm755 acestreamengine "/usr/bin/acestreamengine"
[xiaobai@xiaobai acestream_3.0.3_centos_7_amd64]$ sudo mkdir "/usr/share/acestream/"
[xiaobai@xiaobai acestream_3.0.3_centos_7_amd64]$ install -d "/usr/share/acestream/"
[xiaobai@xiaobai acestream_3.0.3_centos_7_amd64]$ sudo cp -a data lib "/usr/share/acestream/"
之后，在acestream-engine目录中，执行：
[xiaobai@xiaobai acestream-engine]$ sudo install -Dm644 "acestream-engine.service" "/lib/systemd/system/acestream-engine.service"
[xiaobai@xiaobai acestream-engine]$ sudo systemctl start acestream-engine.service
Warning: Unit file of acestream-engine.service changed on disk, 'systemctl daemon-reload' recommended.
[xiaobai@xiaobai acestream-engine]$ sudo systemctl daemon-reload
[xiaobai@xiaobai acestream-engine]$ sudo systemctl start acestream-engine.service
[xiaobai@xiaobai acestream-engine]$ sudo systemctl restart acestream-engine.service
但没有帮助。
之后，直接运行/usr/bin/acestreamengine --client-console --bind-all还会获得类似的错误，例如上面的sh start.sh --client-console --bind-all。
和 --client-gtk，请参阅此线程：
$ /usr/bin/acestreamengine --client-gtk

然后，我也将dnf install m2crypto进行安装的m2crypto-0.22.5-2.fc21.x86_64，否则在运行python acestream_launcher.py acestream://example_for_stackoverflow时将获得ImportError: No module named M2Crypto。
结束[在上面NULL pointer的错误之前]
您可以看到，我在尝试安装AceStream播放器以在Fedora 21中播放Acestream感到多么沮丧。
所以我的问题是，在Fedora 21中安装AceStream播放器的逐步正确的是什么？
