DVD to XSVCD

[weraspamyfamily@aol.com]

Major i tried to rip a VOB...here is the terminal window. It will play on my dvd player but the video lags really bad! Also, is there anyway i can fit this all on 1 cd? i ran out of room but it did finish cd1 first so i could test it! thanks in advance- JAT

It will play on my dvd player but the video lags really bad!

Some DVD players will not support XSVCD. Some will begin play incorrectly but when hitting Pause or Fast-forward they will continue playing fine. Try if the VCD preset (which is also non-standard as it is VBR) does play better on your DVD player. I'm also adding more formats in 0.0.4.

Also, is there anyway i can fit this all on 1 cd?

Enter the duration and "1 CD" and click "Calculate", ffmpegX will set the bitrate to fit on 1 CD. Lowering the bitrate will affect the image quality. You can also manually lower the audio bitrate (affecting the audio quality). Also, prefer VCD image size when using low bitrates.

I tried converting this to vcd also and that worked,but still lagged some. Also, the audio is off sync! I have tried many different methods to convert this and its either lagging or off sync. Could my dvd ripper/extractor be ripping it off sync? im using OSeX and extracting just certain chapters. I dont know what the problem is but i HAVE to figure this out cause it would be awesome if i could make some backups of my dvds! thanks, JAT

Major, I am still having the same problems as this guy. I have now tried every single setting that FFMpeg offers and every possible combination with still no success. (Audio Sync being the issue)

You asked me to set up an FTP site with my clip but I don't have the ability to do that. Besides my VOB clip is 1.5 Gig.

I conclude that since other people are getting it to work fine that my problem is one of the following :

1) I am not ripping it correctly with OSEx
2) My G4 450 Single Altivec is not compatible with your build
3) Road Trip (DVD) can't be ripped
4) I am still not doing something properly

Do the OSEx settings matter ?

PS I have a Pioneer DV-343 And it does play XSVCD, SVCD and VCD

I don't have enough data to tell why it works for someone and not for others. Evidence points to the fact that ffmpeg engine can't correctly resample material so you should always use the same video framerate and the same audio sampling rate as the source. Also, some VOBs seem to always give out-of-sync results, possibly because of segments using different framerates, or other reasons. Altivec is not an issue as ffmpeg is currently not optimized for Altivec.

Apart from that, the encoded file is sometimes reported as being in sync but still having problems or play choppy on a DVD player. I guess this is the result of some DVD players not handling mpeg-1 VBR streams as well as CBR ones. Even if you set large interval quantizers for variable quality encoding, ffmpeg always creates a VBR muxed stream.

Major, can you give a list of VOBs that FFMpeg has worked properly on ? So if I know that they work then I can test them. All this time I have been trying with one VOB which may be one of the ones that you mention above. Then all of my problems could be because that VOB switches frame rates.
