Any source to MPEG2 Transport Stream with multiply audio streams

[traaance]

Hello there.
I'm a little newbie in video conversion. So I'm asking for advise.
I need to convert video from any source (I can download any ) to MPEG2 Transport Stream for our VOD system at my job. And we want that videos would be multilingual so it contains English, French, German... audio-streams.
What is more right to add this audio to source (mkv,avi,vob) or to destionation m2t files? And could you recommend me tools for this. I've been using procoder/carbon coder, but it doesn't understand AC3. So I can't easily convert MPEG4+AC3 to MPEG2-TS+MPEG2. And there are so many different tools which do its own small part of job.
Can you recommend me which tools should I use in this case?
Thanks.

Maybe mplex from mjpegtools.
GfD uses it to multiplex up to three audio streams (AC3 or MP2) into an MPEG file using a command line like

"P:\GUI4dvdauthor\mplex.exe" -M -f 8 -o "q:\A.mpg" "s:\mpg\A.m2v" "s:\mpg\A.ac3"

full syntax:

P:\GUI4dvdauthor>mplex.exe
mjpegtools mplex-2 version 1.9.0 (2.2.7)
Usage: P:\GUI4dvdauthor\mplex.exe [params] -o <output filename pattern> <input file>...
         %d in the output file name is by segment count
  where possible params are:
--verbose|-v num
  Level of verbosity. 0 = quiet, 1 = normal 2 = verbose/debug
--format|-f fmt
  Set defaults for particular MPEG profiles
  [0 = Generic MPEG1, 1 = VCD, 2 = user-rate VCD, 3 = Generic MPEG2,
   4 = SVCD, 5 = user-rate SVCD
   6 = VCD Stills, 7 = SVCD Stills, 8 = DVD with NAV sectors, 9 = DVD]
--mux-bitrate|-r num
  Specify data rate of output stream in kbit/sec
    (default 0=Compute from source streams)
--video-buffer|-b num [, num...]
  Specifies decoder buffers size in kB.  [ 20...2000]
--lpcm-params | -L samppersec:chan:bits [, samppersec:chan:bits]
--mux-limit|-l num
  Multiplex only num seconds of material (default 0=multiplex all)
--sync-offset|-O num ms|s|mpt
  Specify offset of timestamps (video-audio) in mSec
--sector-size|-s num
  Specify sector size in bytes for generic formats [256..16384]
--vbr|-V
  Force variable bit-rate video multiplexing
--cbr|-C
  Force constant bit-rate video multiplexing
--run-in|-R num
  Force a 'run-in' of exactly num frame intervals
--packets-per-pack|-p num
  Number of packets per pack generic formats [1..100]
--system-headers|-h
  Create System header in every pack in generic formats
--max-segment-size|-S size
  Maximum size of output file(s) in Mbyte (default: 0) (no limit)
--ignore-seqend-markers|-M
  Don't switch to a new output file if a  sequence end marker
  is encountered ithe input video.
--vdr-index|-i <vdr-index-filename>
  Generate a VDR index file with the output stream
--workaround|-W workaround [, workaround ]
--help|-?
  Print this lot out!

TS support only limited amount of codecs - so or You write own demuxer with support for "private data" or You will use one of: MPEG-2, H.264, VC-1, Dirac video codecs, audio is similarly limited (however there is more choices) - at first try to play with VLC - it will support transcoding and multiplexing - if this is enough then probably You don't need anything else.

AlanHK, thanks i will look it.

pandy, look. I have aslo IPTV. For example Discovery. It has two audio streams.
And our set-top-boxes support multiply audio streams, so our guests can choose language. And we want to implement this in VOD. As it's very convenient.
I must have my movies in format MPEG2 TS video with MPEG1 layer2 audio. This is vendor requirements. It isn't a problem to convert any video with single audio stream to this format. I actually don't know how to inject many audio streams into this TS. And tag them English, Russian, etc.

OK, first You can use VLC (but You must check syntax for VLC) - as an alternative You can think about http://obe.wikia.com/wiki/Open_Broadcast_Encoder_Wiki or ffmpeg (however there are complains about way how ffmpeg perform multiplexing) or You can try use http://www.avalpa.com/the-key-values/15-free-software/33-opencaster for TS preparation.

Adding multiple tracks is quite easy - there is language descriptor assosciated with each audio track and You can use http://en.wikipedia.org/wiki/ISO_639 for naming of those languages (tracks).

Btw very simple TSMuxer can help You create very quickly TS with multiple audio tracks.
