搬瓦工的VPS不能装ffmpeg么？

chow

各位大佬，小弟最近在研究KVS系统，因为不确定KVS是否能满足自己的需求，所以先购买了一个月的使用期，在搬瓦工上弄了个4G内存的VPS测试研究系统。

结果各种KVS需要的环境安装出错，无奈只能花了99美元请KVS的官方配置服务器，到了安装配置ffmpeg的时候KVS后台一直报错，KVS技术说是服务器CPU指令集权限不够，让我找VPS的技术支持要更高的指令集权限，然后搬瓦工那边又告诉我不能提供最高的CPU指令集权限。。。。WTF，前后各种花费快小两千了，结果现在一个完整的站点还没搭起来。。。请教各位大佬，有没有在搬瓦工上完整配置过ffmpeg的?系统是CentOS 7


具体报错的错误提示如下：

KVS技术跟我说如下：

Please ask your host support to switch the processor emulation mode on this server to host-passthrough , we need this for correct works of ffmpeg library.
We need this for ffmpeg, now we see error "ffmpeg: common/cpu.c:251: x264_cpu_detect: Assertion `!(cpu&(0x0000040|0x0000080))' failed." - that's easy to switch from "QEMU Virtual CPU version (cpu64-rhel6)" to " host-passthrough" or host support can't make this?



然后搬瓦工跟我说：

Unfortunately we are not able to offer host-passthrough cpuid at this time. Do you know what specific flag ffmpeg is looking for?


崩溃中。。。

我知道用VPS搭视频站不现实，我只是先来测试一下，看下系统如何，回头存储和转码肯定要用独立服务器的。

也知道VPS可能会有权限问题，但是没想到一个站点环境都没办法搭建。。。唉。

理论上要CPU特性是因为指令集能加速转码，去掉对应参数也能转，就是速度可能会低一点

虚拟化是可以提供CPU特性的，但是因为有不同CPU指令集不同的原因，不能动态迁移，所以很多商家默认都是关的，也有一部分原因是防止挖矿，这个功能完全就看商家怎么做了

感谢大佬回复，如果说找到ffmpeg需要具体哪条指令集，让搬瓦工客服打开对应的特性，也就可以解决了是么？

瓦工只适合挂个55 正经作战换个别的吧

瓦工大部分套餐都是限制CPU的，计算你装上跑一会儿就给你警告了。

直接用二进制包不行么?
用VPS做视频站的路过

瓦工18刀款
ffmpeg参数太多,懒得一个个查是什么东西,直接复制过来
随便找了个MP4,好像没啥问题
