Author: Omer Osman <[email protected]> Committer: Martin Storsjö <[email protected]> Date: Tue Oct 14 16:43:08 2014 +0200 libfdk-aacdec: Enable Dynamic Range Control Metadata Support For streams which contain DRC metadata, the FDK decoder is able to control rendering of the decoded output. The rendering parameters are detailed in fdk_aac_dec_options []. The default behavior is left up to the decoder.
