4 mai 2013, par rahulgI am fully aware the legal constraints in using
libfaac
but this is just for my testing purpose.I have compiled
ffmpeg

FFmpeg returning an error - What does it mean ?
19 mars 2013, par user1031947I am using FFmpeg, libmp3lame & libx264 along with the node fluent-ffmpeg module. This is my first foray into processing uploaded videos.
From node, I use the following code to process an uploaded video :
var proc = new ffmpeg({ source: src, nolog: true })
.usingPreset( "podcast" )
.withAudioCodec( "libmp3lame" )
.saveToFile( dest, function( retcode, err ){
if( err ) throw err;
...
});When I try to process a video, this fails with the following error, which I don't understand. I am hoping someone here can help point me in the right direction. Thanks !
