Been pretty busy working today, just realized what you meant by command line. I just assumed it was pretty universal on pcm2tsmu input. Here is what was input:
pcm2tsmu.exe C:\movie\hic.pcm C:\movie\hicupdated.pcm -i 24 -c 8 -s 48000

Getting ready to give w64 a try now, hope it comes thru for me.

is this "demux" method lossless? couldn't find any other way to demux a flac from mkv - mktoolnix creates flac inside ogg

Of course it is, you're going from lossless -> lossless.

You didn't look hard enough then. There's a switch to have it just write a raw FLAC track without doing an OggFLAC.

thank you!

ahh, the --no-ogg param, so true

.w64 was a complete bust for me, TS Muxer locked up on two different movies on me (one with TrueHD and the other with DTS HD MA). Both times with this:

LPCM bad frame detected. Resync stream.

Settings for TS Muxer:

MUXOPT --no-pcr-on-video-pid --new-audio-pes --vbr --vbv-len=500
V_MPEG4/ISO/AVC, "C:\Movie\ppl.h264", fps=23.976, insertSEI, contSPS
A_LPCM, "C:\Movie\ppl.w64"

SmartLabs tsMuxeR. Version 1.10.6 http://www.smlabs.net
Decoding H264 stream (track 1): Profile: High@4.1 Resolution: 1920:1080p Frame rate: 23.976
H.264 stream does not contain fps field. Muxing fps=23.976
Decoding LPCM stream (track 2): Bitrate: 6912Kbps Sample Rate: 48KHz Channels: 5.1 Bits per sample: 24bit

Actually though it wasn't a complete bust, it did about 35% of the THD version and about 25% of the DTS before it locked up on me. Both played fine on the computer, haven't checked it out on the PS3 as of yet.

Okay, played it on the PS3 and it came out great for what was there, does anyone know what caused TS Muxer to stop muxing. Or rather why a bad frame was detected. How do I solve this problem.

On what was there, there didn't appear to be any mapping problems (I really like that). The sound sounded pretty much identical, I think I would need two audio systems to be able to check it out.
However the tv upstairs still didn't play it properly, it was like the center channel (main dialog) was missing although on the system downstairs it came thru properly. It's an older receiver (5 years maybe, no hdmi, no advanced audio). Should I swap cables around or do I just need a new receiver.

Thanks to all for you help!

Seems a TsMuxer problem. LPCM (or WAV or W64) don't have frames, only audio data. The audio data can be correct (music, voices, ...) or incorrect (noise, wrong channels, ...) but don't exist a method to detect a bad frame.

Guys.. Is it possible for me to remux my MKVs that have FLAC for audio and change the AUDIO to LPCM? Reason why I am asking is I want to stream my MKVs to the PS3... Am I going about it the wrong way?

Inspector.Gadget · Yesterday, 05:08

Mikelebron: When you create the Matroska file from the original Blu-ray, just output PCM (WAV) audio instead of FLAC. Nothing requires you to use FLAC when demuxing a disc with eac3to...

So I should take this to the TS Muxer section? I saw this problem described over there (in April), but there never was really an answer for it.

I was reading in the thread about first converting it to WAV, then to W64; do you think this would help.

If so how does one go about converting it from wav to w64; I know that eac3to.exe E: 1) 2: C:\movie\movie.h264 3: C:\movie\movie.wav would get it to a wav file (although I've read that wav has problems with over 4G files), but how do you then convert that wav file to a w64 file. I assume it would be a command line, what would that line look like?

I'm going to try to convert it to pcm tonight and see if TS Muxer still has problems with muxing it.

TsMuxer don't accept standard LPCM (.pcm from eac3o), for that I wrote Pcm2tsmu.

TsMuxer always accept .wav files but only <4GB
Last versions of TsMuxer say accept .w64 files (same data than .wav but with a header to support >4GB).

I don't know how solve your problem.
My recommendation is use AC3 640 Kb/s, only with very good audio equipment in a conditioned room you can listen some difference.

dcmo · Yesterday, 20:35

I was going to use pcm2tsmu just to see if it was w64 that was causing the problems and not the discs. I'm sure it's w64, I just wanted to be sure.

After reading some more, what about splitting the file and rejoining them later (that way I could do it in a wav file).

I just can't downgrade the sound; if the choice is between streaming with downgraded sound or not streaming at all then not streaming at all is hands down the winner (it's really not even an option).

I will just go the re-build route and burn it to a physical disc. Anyway can I split them and rejoin them, would I be able to tell where it was happening when I watched it.

Thanks again.
