MLP codec is not standard for BD disks

Post by Failure26 »

Hi,

I have a problem with ripping TRUE_HD Dolby Atmos tracks. When remuxing the MKV to a Blu Ray Folder I get the warning "MLP codec is not standard for BD disks, the m2ts will not play on a Blu-ray player". The BD then doesn't play the movie when on this audio track. After changing to a different audio track it plays perfectly. The MKV plays perfectly on Kodi. The via Handbrake shrinked MKV including the passthrough TRUE HD track put on a BD is not playing on my Sony Player and the XBOX until I change to a different audio track. Then the movie again plays perfectly. What is my problem here, can anyone help?

You must convert the True Atmos audio file with useac3to before muxing.

On BD format TrueHD audio must include legacy core ac3. It is mandatory! Typically backup softwares e.g. MakeMKV remove this core part when matroska is chosen output format as it is considered redundant.

Use

Code: Select all

eac3to source.thd target.thd+ac3
A core part will be re-encoded and interleaved to existing TrueHD only track. After this audio track is Blu-ray compatible and can be used as an asset e.g. in tsMuxeR.
