Pseudo SVCD using OSX ?

[pmcd]

My Panasonic player can't play SVCD's. There is a PC method for tricking it into thinking it is playing a VCD (the method is described here). Is there a simple way of doing that with a Mac under OSX? I can extract the mpeg file if required (for example from a .bin file). But then...?

Seem you forgot to give the URL of the method?

Sigh...it' old age. Anyway here is the link

It seems to be the same as the one posted here

Both use PC tools which is ok except that I was hoping there would be an OSX (Mac) approach.

That's totally weird! Try maybe demuxing with bbdemux and remuxing the streams as VCD with Missing Mpeg Tools. I can't help more as I don't have such a player for testing.

This is what your looking for, how to trick a sony
Note: the next version of MMT will have User Rate VCD / SVCD options.

1. Encode video 480x480 MPEG2
2. Convert the audio stream to 44.1 @ 224 rate mpeg2
3. Since you don't have this as part of the UI you have do it by console

./mplex -V -f 2 -S 2000 -O 0 -o /OUTPUT_DIR/movie-%d.mpg
/INPUT_DIRVID/inputfilevideo.mpv /INPUT_DIRAUD/inputfileaudio.mp2

What I did was change the '-f1' to '-f2'

4. At this point I believe you've done just what people do on the PC, that
is given the MPEG2 stream an MPEG1 header (which is how you trick the sony) and muxed it all together

5. For VCDXGEN select VCD2.0

6. For VCDXBUILD select cdrdao

7. In Toast select multi-track XA and drag the img files over in order

8. Burn your VCD(SVCD) disc, which the sony should play as SVCD.

Hmm...I am confused. Suppose the file is x.bin and you extract the mpeg file as a.mpg. The file now has both a video and audio stream. What utility do you now use? Let's suppose we are in the directory /cdr. Would you then issue

./mplex -V -f 2 -S 2000 -O 0 -o /cdr/a.mpg

?

I am not sure where the ./mplex is living (is it pat of MMT)...

I am also confused as to the 2nd command as well. What would inputfilevideo.mpv be? a.mpg ?

8. Burn your VCD(SVCD) disc, which the sony should play as SVCD.

If the file is now together why do you need 5 and 6 ? Why not just burn in Toast as a VCD?

I'll see if I can clear things up.

The original post was how to play SVCD's on a player that does not support SVCD format.

1) A bin can contain mpeg1 (VCD) or mpeg2 (SVCD), you will need to de-mux or seperate the audio & video. There is a simple de-muxer in the tools section of my site, or the most popular is bbDemux (see VersionTracker).

2) In the above posted example, you would need to substitue your accual directories.

3) The mplex core module (from the mjpegtools project by Linux Square) is embedded in MMT.

4) When the program or system stream (mpg) is de-muxed, the results are a video elementry stream, mpv is genaric for m1v (mpeg1) or m2v (mpeg2) and the audio elementry stream, mpa for mp1, mp2, mp3, ect. Note last charater is "v" or "a".

5) Remember, we want mpeg2 in SVCD format, vcdxgen generates an xml intruction file that spells out the file structure requirements and what controlls the player will have over playback, vcdxbuild puts all these requirement and intructions into a disk image. If the mpeg was dropped into toast, it would simply burn a mpeg onto a data disk, ok for computer, but not to standalone player. If dropped into Toast to burn as VCD, it would be rejected as Toast only wants mpeg1.

I am trying to burn a svcd with a vcd header.
I'm usin the last version of MMT, (user VCD option checked); it gives me a good muxed file, but the it complains that there are underruns in the file.
The file plays in vlc, but I won't have access to the standalone sony player for a few days.
Will it work, or should I use the manual configuration in the terminal?

I haven't tried the latest MMT (are you saying that it can be done without the Terminal now - if so then what would the settings be in MMT?) . Anyway I have used TMPGenc in VPC with great success. The pseudo SVCD's play perfectly (I am amazed at the quality of svcd) . What might interest you is that I always get the "underruns" error message in tmpgenc and warnings that it might not play right (but it always does )...
