  • 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.

  • How to create a DASH VOD for Chromecast with ffmpeg ?

    19 novembre 2020, par Oleg Yablokov

    I need to serve long videos ( 2 hours) from a web server to mobile clients and the clients should be able to play the videos via Chromecast. I have chosen mpeg-dash for this purpose : video encoder is h.264 (level 4.1), audio is aac (although I've tried diffrent ones).

    


    I've tried ffmpeg, MP4Box and some other tools to generate videos ; most of the time I succeeded playing them on VLC or on a mobile client (locally), but not with Chromecast.

    


    I've tried Amazon's Elastic Transcoder and it worked, but it gave me one big file whereas I need many small segments.

    


    CORS are set.

    


    Chromecast remote debugging didn't help much.

    


    Do you know how to do this ?

    


  • Conversion of .dav [Ubuntu]

    3 juin 2018, par Dauas

    I’ve installed ffmpeg on a Ubuntu Linux Amazon EC2 Server and have a Lorex FLIR NVR directly FTP transferring .DAV files to it. In this system a Java program would then tell the EC2 to convert the .dav to but this is where the problems begin, FFMPEG fails to convert the .dav file and to my surprise there is no Codec for .dav (Though I see mention of it once having been supported). I reach out for a solution to this File Format problem, unfortunately the .dav files are a given as the NVR I have is incapable of transfering any other data type over the web, but what is the best way to convert a .dav file on a linux machine ? My Java program has full access to the Shell. It would also be incredibly helpful if anybody were to know how to get their hands on a .dav codec I could test with ffmpeg. I very much value all of your time helping me on this issue.
