Okay i converted .m4a file to .flac using FFMPEG like...
ffmpeg -i filename.m4a filename.flac Using spectro analizer to see the file I noticed the one converted with ffmpeg has compression type of "Lavf54.36.100" while all the others on my computer downloaded from different sources have "LibFLAC 1.2.1". I checked this with at least 20 different flac files from different albums and sources. So my question is what is this "Lavf54.36.100" when all other I checked have "LibFLAC 1.2.1"? Screenshots here! |

Lavf is part of ffmpeg, so that tag means you've encoded the file with ffmpeg.

QUOTE (saratoga @ Nov 15 2012, 20:54)  Lavf is part of ffmpeg, so that tag means you've encoded the file with ffmpeg. IC! So it's kinda like a "signature" of the software trough which the file was created and not the encoder version itself or something like that... Thanks! |

Yes, with ffmpeg but I'm assuming ffmpeg is using the "FLAC sources" to do that and not just any codec... The file with the info "Lavf54.36.100" I'm talking about has a .flac extension...
