I would like to have two seperate audio streams in the SVCD, lets say for two languages.
Do i have to do it in the authoring tool or maybe in the MPEG-2 encoder tool (tmpgenc) ?

DVD2SVCD is the program you need. You can include any 2 audio tracks you like as long as they were on the origianl DVD. Get it from http://www.dvd2svcd.org/

It seems the DVD2SVCD expect a DVD.
But i use a an AVI source from my camcoder.
i want to have two audio strems, one with the original
audio and another with some audio effects.
can DVD2SVCD help ? do i need a different tool ?

I-Author does it as well, but you have to have the audio and video already encoded to MPEG. They have to be seperate elementary streams as well, then use the I-Author mulitplexor. It is not a user freindly program, but works very well.

This is totally simple Just Mux the first audio track to the Mpeg then Mux the second one with the mpeg..You can use tmpgenc"s Mpeg tools for this....

Seems to me that doing it your way would simply overwrite the first muxed file with the second and in the end you'd only have 1 audio track.

Hi,

There are 3 usual ways i know for this:

- Using BBMPEG, you simply mux the 3 separates files (1 video and 2 audio) in one easy step by specifying the 2 audio files... Do not forget to select svcd muxing type...

-Using i-author, similar process than bbmpeg (you specify the 3 files at same time)

-Using tmpgenc, you go in mpeg tools and you select the tab "multiplex" (not simple multiplex!), and then you add the 3 files, the video file, and the 2 audio files and then mux (take care to add the main audio first after video and second audio last). Use the mpeg2 svcd muxing type.

Usually, 1rst audio file will be the default when you play the svcd on your home player. To select, the other, you press the "audio" button and similar. On my pioneer dv343, i can change the audio channel live while playing the video...

Very important detail, you must use simple streams type file, not system or program files, like .mpv for video and .mp2 for audio. I suggest that you use 2 audio with same settigs (same bitrate and mode), to avoid some problems later.

If your main source is a complete program stream .mpg with video and audio, first demux it in tmpgenc mpeg tool in "simple demux" tab to recover separate files for audio and video and then you can process to create like explain in one of 3 ways above.

Good luck!
