  • Streaming filtered video

    4 juin 2013, par tuler

    I have a source video file, h264 encoded, which I would like to apply some filter in real-time and stream it through the web to a HTML5 or flash player (preferably HTML5), like a VOD. This filter can be a grayscale filter, or whatever ffmpeg supports.

    The source video file is stored in Amazon S3, but I can put it anywhere (like the filesystem) if that is necessary.

    I can use any media server if that is necessary, but cost is important. ffserver, wowza, red5, mistserver are all the free or low cost options I have found.

    The stream should be dynamically defined, so I can add a new VOD at runtime.

  • FFmpeg can 'encode' to mp3, but will not accept an 'input' mp3

    21 novembre 2011, par Jonathan Coe

    FYI : 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.mp3

    However, 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.mp3

    I get the following command string :

    FFmpeg version UNKNOWN, Copyright (c) 2000-2008 Fabrice Bellard, et al.

    Any help would be hugely appreciated !

    The input file is in /ebs/queue/input.mp3 and the output is /ebs/converted/output.mp3

  • Upload audio file, convert bitrate, save to S3 | server side options ?

    29 septembre 2011, par Jonathan Coe

    Currently 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.
