Paperclip.Run和FFMPEG退出代码 [英] Paperclip.Run and FFMPEG exit codes

问题描述

我正在使用Paperclip.run命令编写ffmpeg类的回形针处理器。目前，该行抛出一个可卡因:: CommandLineError说明

命令'/ opt / local / bin / ffmpeg -i
/tmp/stream20110729-2442-133evp0.mp3
/tmp/stream20110729-2442-133evp020110729-2442-15k6sr4.ogg
2> / dev / null'返回1.预期0

这不是真的告诉我很多关于发生了什么，我找不到关于FFMPEG错误代码1的任何内容。 >

我需要查找有关FFMPEG发生的更多信息，但似乎错误输出被发送到/ dev / null（Paperclip添加到我的命令中）。

BTW我在OSX Snow Leopard上的Apache 2上运行RoR与Passenger。

我可以收到ffmpeg来记录有关这个问题的更多细节吗？

感谢您的帮助！

解决方案

尝试添加选项：swallow_stderr => false 到Paperclip.run调用。它会指示命令行处理器不要将标准错误重定向到/ dev / null，您可能会收到FFMPEG生成的错误。

I'm writing a paperclip processor that class ffmpeg using the Paperclip.run command. Currently, that line throws an Cocaine::CommandLineError stating

Command '/opt/local/bin/ffmpeg -i "/tmp/stream20110729-2442-133evp0.mp3" "/tmp/stream20110729-2442-133evp020110729-2442-15k6sr4.ogg" 2>/dev/null' returned 1. Expected 0

This doesn't really tell me a lot about what's going on, and I can't find anything about FFMPEG error code 1.

I need to find more information about what's happening in FFMPEG, but it seems the error output is being sent to /dev/null (something Paperclip adds to my command).

BTW I'm running RoR with Passenger on Apache 2 on OSX Snow Leopard.

How can I get ffmpeg to log more details about the issue?

Thank you for your help!

解决方案

Try adding the option :swallow_stderr => false to the Paperclip.run call. It'll instruct the command line processor not to redirect the standard error to /dev/null and you might get the errors FFMPEG is generating.
