![]() ![]() But we don't "merge" the Atmos channels in the core channel count, we display Atmos channel info in separate fields.Įxample of new output with a Dolby Atmos "9.1.4" stream with 1 dynamic object:įormat/Info : Enhanced AC-3 with Joint Object CodingĬommercial name : Dolby Digital Plus with Dolby Atmosīed channel configuration : L R C LFE Ls Rs Lb Rb Tfl Tfr Tbl Tbr Lw RwMost of changes are reversible through options (" -File_HighestFormat=0 -File_ChannelLayout=0 -LegacyStreamDisplay=1" on the command line) but I hope that these option are used not so much. ![]() We support now the channel configuration and the count of objects in an Atmos stream, either in E-AC-3 or TrueHD. "E-AC-3 JOC" for Dolby Atmos in E-AC-3, "MLP FBA" for TrueHD and "MLP FBA 16ch" for Atmos in TrueHD. ![]() We do the difference between technical name and the marketing name, e.g. Channel layout names will be in MediaInfo 18.08 and above, with a list ordered by the expected output order from the decoder, the former method is still available with "full" text, XML or API (list is ordered by "layer" so comparison is doable between formats, but similar channels have the same name and/or it is not well implemented, be careful with this field if you work with 16- or 24-channel content) Note that issue with having channel names is that each format stipulates different channel names, we listed the mapping we do at. The previous method was not sustainable with the incoming 3D audio (16 or 24 channels). We change the way we display channel layout, with a list of channels. We don't display anymore by default information about how legacy decoders would play the file. "Profile" field has changed for AAC, now contains the profile/level as found in MP4_IOD_Tag MP4 descriptor. Note that there are sometimes some differences between "Format/String" and the 2 other fields for commercial reasons. the "Format" field in XML or API (or "full" text output) contains the base format, "Format_AdditionalFeatures" field in XML or API contains the list of features, "Format/String" for the sum of both. the Format line in the text output contains now the name of the base format + list of features needed for outputting the best result. We change how we display formats with support of legacy decoders: This was actually becoming difficult when we implement a better support of E-AC-3 in Bluray (mixed with core AC-3) and also Atmos (can be in E-AC-3, or TrueHD, TrueHd may be mixed with AC-3 or alone.), and DTS-HD features were not well displayed enough. Due to the increasing complexity, while keeping compatibility with legacy decoders, of audio formats, the way MediaInfo was displaying audio related information was worse and worse. ![]()
