m2ts with DTS to m2ts with AC3

[Colin_S]

Hello,

I have been trawling through forums and web sites trying to figure this out.

I have a M2TS file with dts that i want to play from my PS3 HD so need to convert the DTS file to AC3. I am having real trouble pulling the DTS file out of the M2TS file, converting to AC3 and then remuxing them.

Can someone please help, i think the bit i am struggling with is demuxing the M2TS file into a video and audio file where i can then convert to AC3 using eac3to and then remux with TSMuxeR. I have looked for xport but can't find it, but i'm not sure that is the correct program to use when i want to convert the DTS audio once demuxed.

Please help.

Thanks in advance

Colin

Hi!

Doesn't your original source (The one you from which you created the M2TS file) contain an .AC3 audiostream, as well as a .DTS audiostream?

[Colin_S]

It only has a DTS track.

[setarip_old]

I'm not personally aware of any such commercial DVDs/HD-DVDs/BluRay. What's the Title and Region of your original DVD or HD-DVD?

[Colin_S]

Don't want to sound condescending but do i really need to go into detail? I am 100% there is only a DTS track.

Thanks for your input though with no sarcasm.

I was simply seeking further personal education regarding any new type commercial products that may be out there - mainly because I've always understood that commercial DVD standards REQUIRE that a DVD (even if it contains a DTS audiostream) contain either an .AC3 or LPCM audiostream.

Perhaps another member will offer you further assistance...

Didn't mean to offend, just didn't want to go into detail as it is not exactly commercially available.

hI,

http://www.w6rz.net/xport.zip

Typical usage for Blu-ray is:

xport -h movie.m2ts 1 1 1

got xport now, but have no idea how to make it work. When i run it a cmd screen pops up for less that a second then disappears.

C:\Documents and Settings\Colin\Desktop\xport>xport -h 0000.m2ts 1 1 1
Cannot open bitstream file <-h>

C:\Documents and Settings\Colin\Desktop\xport>xport -h 0000.m2ts 1 1 1
Cannot open bitstream file <-h>

Usage is:

xport <-pavtdszgh> <infile> <program number> <video stream number> <audio stream number>

typically:

xport something.ts 1 1 1

The output files are always named bits0001.mpv for video and bits0001.mpa for audio
(note that bits0001.mpa can be an AC-3 file). For AC-3, MPEG-1 Layer 2 and Blu-ray
LPCM audio, the demuxer will time align the beginning of the two elementary streams
so that a remux to PS or back to TS will have correct A/V sync. The -n option has
been deleted.

Options:

p = parse only, do not demux to video and audio files.
a = dump audio PTS.
v = dump video PTS.
t = GOP timecode mode, count repeated fields/frames.
d = dump all PID's (useful for debugging muxers, but tons of output).
s = suppress TS rate dumping (useful when piping output to a file).
z = demux to PES streams (instead of elementary streams).
g = dump ATSC PSIP information.
h = input file is in HDMV (AVCHD and Blu-ray) format (192 byte packets)
2 = only extract 2 channels of HDMV LPCM audio from multi-channel tracks.


The -h option is for Blu-Ray and HDMV (AVCHD) content only. That's why it is probably useful to know where this TS is coming from.

I've always understood that commercial DVD standards REQUIRE that a DVD (even if it contains a DTS audiostream) contain either an .AC3 or LPCM audiostream.

Well, thats indeed almost true for a DVD (IIRC there must be at least one AC3 track), but i'm not aware of any commercial DVD that contains a m2ts file... :p

However, for BluRays it seems quite common to only contain DTS tracks and even a DTS HD Master Audio track just to be able to argue "This simply won't fit on a HD-DVD" ;).

@Colin_S
It's a command line program, it has to be started from a console window. Despite to check if the -h switch is necessary, you have to specify the full path to the file if its not in the current directory and maybe the file uses different stream numbers.

:rolleyes:

also mp2 for pal :)

This original was a HD-DVD and has been remuxed and a Blu-Ray created. I have then extracted the m2ts file from the Blu-Ray files so i'm guessing the -h should be the correct option to use but it doesn't seem to work.

I have my m2ts file in the same directory as the xport file and as for streem numbers i would assume that it is 1 as there is only the 1 video and 1 audio stream in the file.

Why don't you extract the audio directly from the source HD-DVD?

Don't have the means to extract anything from HD-DVD

Don't have the means to extract anything from HD-DVD Therefore you didn't make the M2TS file. Thread closed. Please read and follow our forum rules.
