Hello, is it possible to calculate the checksum of binary data fields to see whether they are identical (e.g. the covers are the same picture )?<br><br><div class="gmail_quote">On Wed, Mar 17, 2010 at 3:50 AM, Scott Wheeler <span dir="ltr"><<a href="mailto:wheeler@kde.org">wheeler@kde.org</a>></span> wrote:<br>

</div>Notably, in formats that have containers (Ogg, et al) just finding the<br>
data that's "not the tags" isn't sufficient (like it would be for MP3)<br>
since changes at the beginning file can require changes in all<br>
subsequent blocks. libsndfile is probably the thing to look at<br>
(though it will give you actual audio data, not compressed data).<br>
