PHP exec调用ffmpeg自动转码视频不执行了
给一客户做PHPCMS的字段开发，实际上传视频转码功能，本机测试通过，UAT环境也通过。客户上传到生产环境后转码不执行了，UAT环境与生产环境一样，都是WIN2003+IIS6.
CMD.EXE与ffmpeg.exe的权限都给了，everyone,iis,guest等，全部是完全控制，运行exec('ipconfig');可以正常输出用户IP信息，证明CMD.EXE权限没错，但是运行exec('ffmpeg.exe -i test.wmv test.mp4')这样的命令始终无法执行.可以排除ffmpeg.exe与视频文件的路径问题，相对路径与绝对路径都测试过了。
GOOGLE，百度找了一堆资料，还是无解，有没有大神帮忙分析下可能会是什么原因？
回复讨论(解决方案)
又搜到自己的问题了，求人品
这种东西还真不好说问题出在哪，基本上要排除的错误问题你都已经排除过了，在单独的执行这个转码指令功能是正常的吗？或者将你的这个功能部分到其他的win2003系统上再做个测试看看。
ffmpeg.exe 需要有匿名用户执行权
ffmpeg.exe与视频文件都需要使用绝对路径
你可以通过 php 文件同目录下的 cmd 文件来验证这一点

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
