I'm trying to sync some DVDs I have ripped previously to my iPod, but when I ripped them I only ripped the AC3 audio stream as that's all I need on my system.

The problem is that although conversion works and the DVD title appears on my ipod (8GB nano 3rd gen) there is no sound.

When the title is in the queue it shows "AC3 6 Channel" for the DVD Rip Info.

Should the conversion process convert the AC3 audio stream down to something that will play on the iPod? 

Thanks
Richard

Is AC3 played with QT or with DirectShow in MC?

Directshow on my system.

Don't know.  You could try ffmpeg manual conversion.

Don't know.  You could try ffmpeg manual conversion.

It appears that MC uses ffmpeg to do the conversion, and the ffmpeg.xml file under plugins has this line.

Code: [Select]

<ipodnative>-y -acodec libfaac -ab 128kb -ar 44100 -vcodec mpeg4 -b 1200kb -r 30 -s 320x240</ipodnative>
I just need to know how to change this line to force AS3 6 channel to be converted to stereo I guess.

Anybody know their ffmpeg syntax please?

I've tried adding

Code: [Select]

-ac 2 to the command line, but I still get no audio.

In fact I tried an AC3 2 channel stream and I still don't get audio.

Not sure if it's a problem on my system or in general.

Has anybody  sync'd DVDs to their ipod successfully from MC?

Cheers

I have just tried converting a .vob file manually with ffmpeg and then using MC to transfer it (with no conversion) to my nano.

The command I used was

Code: [Select]

ffmpeg -i X:\Video\DVD\Movies\Madagascar\VIDEO_TS\VTS_01_1.VOB -y -acodec libfaac -ab 128kb -ar 44100 -ac 2 -vcodec mpeg4 -b 1200kb -r 30 -s 320x240 c:\tempipod_test.mp4
which is the same as that defined in the ffmpeg.xml file for ipodnative conversion (with my -ac 2 added)

Doing this I get sound on the ipod, so I know the ffmpeg conversion is working correctly.

I then did another conversion/transfer using MC and yet again I get no sound.

So there is something wrong with what MC is doing....

I need to resolve this... does MC combine the .vob files before conversion?

is it possible it's at this stage sound is being lost? althoough if i convert to psp on my hdd i do get sound...

is there a temp file created I can check?

It's been a while since I converted a DVD for a device, but it gives you options for the format.  Are you choosing the right one for iPod?  There is a PSP option that will also play on other devices.  I believe it's MPEG2.

It's called "Native ipod", one would hope this is the correct one for an ipod?

As I said, if I use ffmpeg manually with the same parameters as the nativeipod line in the ffmpeg.xml a selected .vob file converts fine, but if I drag the DVD as MC imports it,  onto the  ipod from within MC it isn't beiong converted correctly (with native Ipod selected for video conversion.)

I don't have an answer, but I'm trying to learn.  How did you rip the DVD?

I don't have an answer, but I'm trying to learn.  How did you rip the DVD?

I used CloneDVD and ripped it to a folder as DVD files (Video_TS etc) and then just import that folder into MC.

Jim/Matt,

I really need some help here, I'm going on a 10 hour drive with my 3 year old next week, and a 6 hour plane flight the following week, so I REALLY need his DVDs on my ipod before we head off!

 I really don't want to risk having to install itunes on my system, but I just can't get MC to convert/sync DVDs with audio.

I have tried the Ipod Native and Ipod TV settings, both drop the audio.

As per above messages ffmpeg can convert a .vob file fine manually but MC isn't for some reason.

I'm not sure what's happened to your peson who used to look  after all the handheld stuff, was it John? But I really do need to get this working.

My only other option is to convert them all with something else, import the files into MC and assign cover art and then sync them with MC, but I'd really like to just queue them all up overnight and leave them to convert/sync which won't be so easy with the alternative utilities I have.

Sorry to be a pain
Richard
