Maximum buffer size is managed with high granularity in WPE by using the MSE_MAX_BUFFER_SIZE environment variable. For that reason, that call must happen independently of the kind of tracks present (at least on the WPE platform). This will ensure that the proper frame eviction code in SourceBufferPrivate::setMaximumBufferSize() is called in all cases.
