# Proprietary media support

Vivaldi does not directly bundle any library with support for
"proprietary media" (H.264/AAC), since this would make redistribution of
the output package difficult (due to software patent licensing).

Instead a library to support this will be installed on first startup.

To test proprietary media works as expected go to the following page and
attempt to play the video:
