I know that's the claim, but I can hear the difference in some recordings. For example, in The Beatles "A Day in the Life". there's some low level vocals in the middle that seem to disappear in the ogg file. I can also hear artifacts that have been added when creating the file. BTW, I use K3b when making ogg or mp3 files.
compresses it again to another lossy format. Two lossy conversions chained. Thus, worse overall result.
That may be the case when converting back to original and re-encoding. But what about taking the compressed data and then "repackaging" (for lack of a better term). Which does ffmpeg do? I suppose the only way to find out is to compare a converted file with one made from the source. However, beyond my ears, I have no way to do that. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
