  1. So I have my workflow down a simple set of apps with very few steps. I use eac3to command line to demux, BDSup2Sub to do any subtitle manipulation/inspection and mkvmerge to put it back together. The issue is that I can't use mkvmerge to mux titles with lpcm audio since it isn't support. I can't find any muxing tool that support lpcm audio. The only way I've been able to do this is to convert the lpcm audio track to flac or use MakeMKV. I'm not sure how MakeMKV does it but it seems to be the only tool that can mux lpcm audio.

    Does anyone know of any software that will mux lpcm?

  2. No one? Am I the only one who uses XBMC/Plex with bitstream audio that wants HD audio from titles that use lpcm?

  4. Any BD with lpcm audio. How do people mux into a single file (mkv or other) to bitstream from a HTPC with HD audio? Is it not possible?

  5. tsMuxer can mux different kinds of video together with LPCM audio into several different formats.

    tsMuxer doesn't seem to be able to handle the lpcm track straight from disc. It needs to be muxed into a wav container first. Then I can mux it into a mkv but the issue still remains that with XBMC I can't bitstream that audio straight to the receiver. I'd need to go in and change my audio settings to analog before it will play.

    Supported audiocodecs:

    * AAC;
    * AC3 / E-AC3(DD+);
    * Dolby True HD (for streams with AC3 core only);
    * DTS/ DTS-HD;
    * LPCM.

    Maybe LPCM tracks aren't all created equal. Or maybe eac3to does something to it during the demuxing. I don't know as I use WAV files and it muxes them easily.
    ...but the issue still remains that with XBMC I can't bitstream that audio straight to the receiver.
    That wasn't your original question here.

    I have no idea about the XBMC problem. Maybe someone else can help. Sorry, not much help.

    True. I have a couple threads on different forums about these related hurdles with lpcm and I got my questions mixed up. I've learned over the past day or so that muxing the lpcm into wav is the correct and possibly only way to get it back into an mkv or m2ts. I'm starting to think my playback issues with that might actually be my receiver. It must not be able to decode the wav files for some reason.

    WAV and LPCM are often referred to interchangeably. Close enough, but there are distinctions. WAV is an IBM/MS container format. It most commonly contains LPCM, which is a lossless audio encoding method. It's possible for a raw LPCM file to be dragged down to the last bits to a PC hard drive. But unless it's wrapped in a WAV container (automatically on the fly while being imported, or not) on the drive it's not much use to tsMuxer or most other Windoze apps. In a similar manner, CD-audio also has LPCM; when it is extracted, it lands on the PC hard drive
    automatically as WAV.
    For the nth time, with the possible exception of certain Intel processors, I don't have/ever owned anything whose name starts with "i".

  10. So when Clown_BD remuxes a title with lpcm it rips the lpcm track as wav and then converts it to w64 then muxes that into the m2ts. mkvmerge doesn't seem to be compatible with w64 but it works with the wav file. They both seem to work fine (neither will bitstream as pcm though) so is the conversion to w64 necessary?
