Audio not in "sync" after ripping dvd using acidrip

kernel_geek · 01-05-2007, 03:51 PM

Hi i have been ripping dvds for some time and whenever i play them back in mplayer or a re-encoded version for my mp4, the audio is out of sync, about a second. Any idears how to help this ?? This is one of the commands acid rip was using to encode (wallace and gromit

, those of you who live in UK): mencoder dvd://16 -dvd-device /dev/dvd -alang English -info srcform="DVD ripped by acidrip.sf.net" -oac mp3lame -lameopts abr:br=128 -ovc lavc -lavcopts vcodec=mpeg4:vhq:v4mv:vqmin=2:vbitrate=2736 -vf pp=de,scale=800:-2 -o "/home/chris/wallace_and_gromit.avi"

From the man page for mencoder:

Quote:

GENERAL ENCODING OPTIONS (MENCODER ONLY)

-audio-delay <any floating-point number>
Delays either audio or video by setting a delay field in the header (default: 0.0). This does not delay either stream while encoding, but the player will see the delay field and compensate accordingly. Positive values delay the audio, and negative values delay the video. Note that this is the exact opposite of the -delay option. For example, if a video plays correctly with -delay 0.2, you can fix the video with MEncoder by using -audio-delay -0.2.

Currently, this option only works with the default muxer (-of avi). If you are using a different muxer, then you must use -delay instead.

Have you tried this?

Ok thanks, but how do i work what delay to use ??

Load your movie into MPlayer and use - and + to adjust.

kernel_geek · 01-07-2007, 02:07 PM

What + and - keys ??

lurko · 01-07-2007, 06:25 PM

the ones on the keypad... or the 2nd from top row of the keyboard (you have to use shift to get the + though)

maybe try it with constant bitrate audio(? idk just guessing). Not sure why ABR/VBR would start being a problem all of a sudden, but you never know.

Ok i will try thanks. Also i noticed that the new encoded version is realy quiet how can i solve this (ie what option in mencoder do i use ??

lurko · 01-09-2007, 06:32 AM

normalizing the audio might do the trick, but I wouldn't want to do that. It says here there is a an option for input gain (at least for lame), -vol=<0-10>. I just learned about this option now, when I read it on that page, so I can only say it looks promising.

If you use the software mixer in MPlayer, you can increase the maximum volume to any degree you wish.

mplayer -softvol -softvol-max 200 file.avi will make the max volume 200% of normal. The only drawback is less precise volume control, as the volume up/down keys increase or decrease the volume by a percentage of the max volume. Really though, it's not much of a drawback.

have a look through the MPlayer/Mencoder manual for more options.

Yeah that sound prommosing, Its just that my iriver dosent use mplayer

. I will try the encoding method.

kernel_geek · 02-08-2007, 04:03 AM

Thanks, the vol option worked, and I used diffrent encoding optons to get it in sync, many thanks.

It would be useful to tell us what those options were!

Ok well this is what I used I think to convert a dvd or file , to watch on my iriver u10 (a little script I made)

Thank you!
