It's really annoyingĮac3to "C:\Users\User\Desktop\00466.m2ts" "C:\Users\User\Desktop\ out.thd"Įac3to "C:\Users\User\Desktop\00466.m2ts" "C:\Users\User\Desktop\ out. Mkvmerge can't mux the TrueHD / Atmos that contain AC3/DD5.1 core, it just can mux the TrueHD / Atmos stream and the AC3/DD5.1 core stream separately.
> The fact, not all TrueHD / Atmos contain AC3/DD5.1 core, it's because: The ac3 encode sounds louder & more like dts (in crash scene) than the ac3 core TrueHD/AC3 (Atmos), 7.1 channels, 48kHz (embedded: AC3, 5.1 channels, 448kbps, 48kHz, dialnorm: -27dB)Įac3to "C:\Users\User\Desktop\00466.m2ts" "C:\Users\User\Desktop\out.thd+ac3"Įac3to "C:\Users\User\Desktop\out.thd+ac3" "C:\Users\User\Desktop\core.ac3"įfmpeg -y -threads 12 -loglevel fatal -i out.thd+ac3 -ac 23 -ar 48000 -f sox - | sox -multi-threaded -ignore-length -S -t sox -t sox - | ffmpeg -y -threads 12 -f sox -i -b:a 448k -ac 6 -ar 48000 encode.ac3įfmpeg -i out.thd+ac3 -c:a ac3 -ac 6 -b:a 448k -r:a 48000 encode_2.ac3 Does ffmpeg normalise? That'd tend to increase the volume a little. If I'm re-encoding multichannl audio as multichannel audio I tend not to change the volume in the process. If you open the thd+ac3 extracted file with MKVMergeGUI it shows two individual streams, so it's kind of like the thd+ac3 are together in a container which is in turn inside the m2ts file on the disc. It shows a single TrueHD stream you can extract with a thd+ac3 extension, with a thd extension or with an ac3 extension, and that gives you both thd+ac3 together, just the TrueHD or just the AC3 respectively. I haven't worked with much TrueHD audio but if you open a Bluray title using MeGUI's HD Streams Extractor (a GUI for eac3to). So if a Bluray title was to contain only Dolby audio, it'd have to contain AC3 as it's one of the compulsory formats.Ĭhances are some of the budget model Bluray players only supported the compulsory formats, at least in the early days.
The newer formats, Dolby Digital Plus and DTS-HD High Resolution (lossy) and Dolby TrueHD and DTS-HD Master Audio (lossless) are all optional. BD-ROM titles must use one of those types for the primary soundtrack.
If you have any questions or would like to tip us on some point here, feel free to do so in the comment box below.Plus for Bluray there's three compulsory formats all players must be able to decode. That’s it guys, after following the steps you’ll find that all your DTS DOLBY DIGITAL Audio Files play pretty smoothly on the Player. If Custom Codec is loaded, it will show the platform & custom codec version below the MX Player version info. Check whether the codec is loaded or not.
History: See Dolby History (link available through Internet Archive).
If you have selected the right zip file MX Player will automatically restarts else it will revert with error (“Can’t find custom codec for this version”). QT AC3 Codec provides information about a software component that permits AC-3 playback in QuickTime players. Navigate into the folder you have saved the file.Go to Settings 》 Decoder 》 Custom Codec.zip package from here, if you don’t know which type of device you use. Developers at XDA-Developers have found a feasible solution to the problem- using a custom codec and adding it to MX Player and this is how you’ll have to do it.
