# We are currently keeping the message level 'error' separate from the
# PlayerError type because right now they represent different things,
# this one being a DVLOG(ERROR) style log message that gets printed
# based on what log level is selected in the UI, and the other is a
# representation of a media::PipelineStatus object. Soon however we're
# going to be moving away from using PipelineStatus for errors and
# introducing a new error type which should hopefully let us integrate
# the error log level into the PlayerError type.
