This is the MPlayer samples collection.
You can find samples of various common and uncommon
multimedia formats here. The size of the collection
currently is 187GB and growing.

You are free to download any samples you want, but
if you want to download the entire samples archive,
please send a mail to webmaster(AT)ffmpeg(DOT)org
*before* you start, as we like to know what they are used for.

Please be aware that this samples collection contains a lot
of files that are very obscure, broken in various ways or
are just simply not useful for 99% of people. Hence, it doesn't
make sense to download all of them, unless you are developing
a player application that will support all and every file format
that was ever conceived.
