A way to convert bitrate/format of audio files (between upload & storage to S3)
5 octobre 2011, par Jonathan CoeCurrently using PHP 5.3.x & Fedora
Ok. I'll try to keep this simple. I'm working on a tool that allows the upload & storing of audio files on S3 for playback. Essentially, the user uploads a file (currently only allowing mp3 & m4a) to the server, and the file is then pushed to S3 for storage via the PHP SDK for amazon aws.
The missing link is that I would like to perform a simple bitrate & format conversion of the file prior to uploading the file. (ensuring that all files are 160kbs and .mp3).
I've looked into ffmpeg, although it seems that the PHP library only allows for reading bitrates and other meta, not for actual conversion.
Does anyone have any thoughts on the best way to approach this ? Would running a shell_exec() command that performs the conversion be sufficient to do this, or is there a more efficient/better way of doing this ?
Thanks in advance ! Any help or advice is much appreciated.

FFmpeg can 'encode' to mp3, but will not accept an 'input' mp3
21 novembre 2011, par Jonathan CoeFYI : Fedora 8 running on Amazon EC2...
Having a difficult time with FFmpeg doing a (what should be pretty simple) conversion. I can get FFmpeg to encode an mp3 file from an m4a file using the following :
ffmpeg -i file1.m4a -acodec libmp3lame -ab 160k file2.mp3However, I cannot get it to to convert an mp3 -> mp3, it responds with "Unknown Format" using the following :
ffmpeg -i file1.mp3 -acodec libmp3lame -ab 160k file2.mp3I get the following command string :
