LayoutTests/media/content/opus_variable_witherror.webm plays fine in VLC and in GStreamer-based players. What's supposed to happen when that file is loaded, exactly?

The track Id is 2^64 which is an illegal value. This is handled properly by libwebm parser and it will return an error when parsing the metadata

Ah, that might explain why it plays in GStreamer then, since AFAIK we don't validate track metadata there...
