MeGUI - X264 to IPod

[Sharktooth]

the mp4 muxer window has the ipod option too.

[CKHSJ]

quicktime probably has some sort of post processing built in.

what?

Sharktooth

Is there any good app that could sync audio and video streams obtained from a matroska container?

I've used dgavcindex and after I convert the *.h264 to mp4(ipod profile) and mux it with the aac audio file, they're out of sync. Nothing that I tried helped. I converted the audio to mp3 as I've read that *.aac format is not syncable.
I tried mp4mbox with all the guis I could find, but can't sync the audio&video.

[Sharktooth]

that's a MP4Box known issue. try replacing the mp4box that comes with megui (tools folder) with this one (includes both 32 and 64 bits builds): http://www.mediafire.com/?1fu44g35otxf1ei
see if it helps and report back :)

If you are using Megui's MP4 muxer, make sure you select the correct FPS for your reencode when muxing. I have found that the correct FPS is not always detected correctly for x264 streams, but if you set it to your reencodes FPS, the mux has audio sync.
A few recent attempts from Blu-ray to Ipod were perfectly in sync after selecting 23.976FPS from the drop down arrow, where Megui had set 47.952FPS. :confused:

[Sharktooth]

ipod requires Baseline profile and mp4box had a known bug with newer x264 versions, expecially with baseline.

[hardkorn]

Tried the gpac mp4box compile, thanks for this, but the A&V are still out of sync.

[Sharktooth]

Then follow the Capsbackup suggestion.

@hardkorn & others: according to this (http://forum.doom9.org/showthread.php?p=1441995#post1441995) it's a mediainfo bug and should be fixed in the next version.

[Sharktooth]

the problem should be fixed. run the auto-update and ensure you get the new mediainfo package.

[hardkorn]

Which mediainfo.dll should I use? The one LoRd_MuldeR compiled or the one from the mediainfo package from the project's website, because they both are v 0.7.35.0 but different sizes. Megui autoupdate doesn't detect a 0.7.35.0 v but still the 0.7.33.1 version.

edit: nevermind I edited settings.xml http://megui.org/auto/stable to http://megui.org/auto/

[hardkorn]

Is it necessary to add a special metatag to mp4 files so they're compatible with iphones/ipads or does the mp4muxer's ipod option takes care of that too?

[Sharktooth]

the ipod option is there for that reason.

[hardkorn]

back again

For some reason one of my encoded files isn't copied to my ipod. Another file encoded using the same ipod megui profile is compatible, but this one won't.

I used the autoencode option so it was ipod tagged but it is not compatible. Another test segment from a DVD source is fine. Same settings, profile. The source is an xvid file though. Does that make a difference?

[j8ee]

Isn't the max bitrate too high?

[jethro]

if you're using iTunes to copy and it complains, try SharePod for this file.
