Important Information

It is important to keep in mind that the results of the robustness check depend on the audio and video content type. If an invalid or unsupported audio/video content type is specified within the requestMediaSystemAccess() call, the results will be negative regardless of the robustness parameter. As a consequence it might be useful to check different content types especially on mobile devices. EME spec states the following:

In order for the capability represented by this object to be considered supported, contentType must not be the empty string and its entire value, including all codecs, must be supported with robustness.

You can select a different content type in the input fields below. The test will iterate through all possible combinations.
