muxing out of sync?

[punkface]

ive started to get the hang of decoding with mplayer but it fails to create a single mpg so ive tried muxing them together but the syncing is terrible,

required(DTS)=2571000
++ WARN: [mplex] Video e0: buf= 233219 frame=000701 sector=00004110
++ WARN: [mplex] Audio c0: buf= 4096 frame=001168 sector=00000342
**ERROR: [mplex] Too many frame drops -exiting

too many frames??

[major]

Which kind of settings (bitrate, profile, etc) did you use to encode it?

[punkface]

mpeg2 (mpeg2enc)
video bitrate: 2300
video size: 352x576
audio codec:mp2
audio bitrate: 224
sampling: 48000hz
Mode: CBR
profile: generic Mpeg-2
Q Matrix: Standard
Interlace: Not interlaced
Thread: Normal
vbv Size: 230kb
Sync: 0 ms
QMin: 5

is that enough info? thanks for your help

Try to use XSVCD profile instead of generic mpeg-2.

slightly better but still compltely out of sync any other ideas or should i just give up?

[major]

If it is out of sync then it should be an encoding problem, not a mux problem. Did you change framerate going from source to destination? Did you use "Decode with mplayer" or "Decode with Quicktime"? Which framerate was your source?

[punkface]

video[24pm] 480x360 24bpp 23.98
fps 1017.8kbs (124.2 kbyte/s)
audiocodec:framecopy (format =55
chans =2 rate =44100 bits =0 bps=23999

thats the source info, then i chose a high dvd preset and changed it from nstc to pal, could the pal change over be anything to do with it?

[major]

Yes, you should always keep the same framerate as the source movie to be safe.

[punkface]

thanks major, but now i cant watch the dvd on certain dvd players is there any way of getting around this?

[major]

If you absolutely need to change framerate, you should prefer "Decode with quicktime" though such conversion is always sound-sync risky.

[Case]

now i cant watch the [NTSC] dvd on certain [PAL] dvd players

[nitpick]
Almost all DVD players sold in PAL countries play both kinds of discs. These multi-standard players can partially convert NTSC to a 60-Hz PAL (4.43 NTSC) signal. It’s the old/simple tv sets in PAL countries that can’t handle such a signal.
Most NTSC players can’t play PAL discs.
[/nitpick]

i have quite a smart dvd player which plays nstc, but what i was aiming for was my gf's ps2 which plays nstc encoded in black and white

oh well

[Case]

If the black and white picture is stable (i.e. not rolling), then the tv set understands PAL-60. Then she can get a color image if she connects with an RGB signal through a full SCART cable.

[punkface]

the pictures fine apart from the fact its black and white, whats this you say about a RGB signal? this would be great because we have quite a few nstc dvds, please tell me more...

[Case]

XBOX usually delivers Composite Video output + Stereo output. With an "Advanced" cable, users can enjoy RGB video (& optical SPDIF audio).
I suppose you'll have to change a setting in the On Screen Display to switch from Composite Video to RGB.
Assuming that the tv set has a SCART input socket, and supports RGB signal input. SCART can carry Composite, S-Video and RGB, so not all tv sets with SCART are required to accept RGB (but most do). Picture sharpness and colour quality will be noticeably better with RGB.
I think the XBOX SCART output socket is non-standard, so an ordinary SCART cable (with all 21 pins connected (needed for RGB)) is no good. One side of the cable has to fit the XBOX after all. So you'll need the XBOX version of the cable.

what about this?

[Case]

Different method, but it should work. Results should be similar to a DVD Player than can do NTSC to true PAL internally.

Or if worse comes to worse, the Apex 1225 is running 39.00 USD, and can play pretty much anything, I've got one, and it's just fine for NTSC/PAL
