通过命令行将*（mp3，m4p等）转换为OGG，以实现HTML5兼容性

Question

What options do I have for converting MP3's to OGG on the fly using PHP? I assume the only way to do this is via the command line with an execute statement. Is this true? If so, what converters (and associated commands) would I be best off using?

I have tried:

oggenc2.exe but was told by the program that the MP3 I passed was not a valid filetype

ffmpeg.exe but was unable to figure out how to go from mp3 to ogg (found how to go from ogg to mp3 though)

Convert mp3 to ogg via php

Answer 1

You didn't look very far...

exec("/usr/bin/ffmpeg -i infile.mp3 -acodec libvorbis outfile.ogg");
