Ubuntu Multimedia :: Audio Out Of Sync When Burning DVD Images?

Jun 20, 2011

I am burning DVD iso's and they seem to work great I have video output and sound output however as the film goes on the audio gradually becomes more out of sync but if I hit the rewind button on my remote and then play the sound is in sync again for a few minuets. I am using DeVeDe and Gnome Baker to create and burn my iso images to disc and they work great on the computer but not so great on my dvd players I am burning onto Verbatim DVD-R using Ubuntu 10.04 lucid lynx.

Ubuntu Multimedia :: How To Sync Audio On Already Badly Out Of Sync Video?

Jul 9, 2011

Audio sync method. "Stretches/squeezes" the audio stream to match the timestamps, the parameter is the maximum samples per second by which the audio is changed. -async 1 is a special case where only the start of the audio stream is corrected without any later correction.Searching the net makes one believe that this command is just some sort of magic.People just put it in the line and it just works. Isn't that nice?

It says nothing about how to change the TIME the audio starts syncing. Like do I want it to start 5 seconds delayed? Or what about 5 seconds sooner?What if the audio gets more out of sync as the video goes on? Can I slip it a little at a time? What? No magic?No one mentions a file that already has badly synced audio.So what -async 1 really does is simply start the audio at the beginning of the file. LIKE AS IF THAT ISN'T STANDARD PROCEDURE?So what is the exact solution to syncing a messed up video? And why can't it just do the proper "timestamp" sync in the first place?No docs, no info and you are left out in the cold.

Ubuntu Multimedia :: Burning An Iso Audio Image With .inst Header?

Jun 1, 2010

I've bought Earthworm Jim 1&2 from gog.com thinking that i could play it on my old Pentium 2 computer running DOS.

The problem is the game requires it's soundtrack CD, which is suplied by GOG in the form an ISO image with a .inst file that acts as some kind of header(just like a cue file is to a bin image). It contains details about the tracks. But i have no ideea how to burn it. Brasero will burn it, but it's unreadable. K3B doesn't seem to like it.

DOSBox has no problem mounting this type of image, and the game works fine after i've mounted the image.

So the question is, how should i burn this type of file(ISO Audio Image with .inst header)?

I'll also post the contents of the .inst file

Code:
FILE "EWJ1.gog" BINARY
TRACK 01 MODE1/2352
INDEX 01 00:00:00
TRACK 02 AUDIO

[Code]....

Ubuntu Multimedia :: Audio Out Of Sync After Upgrade To 10.10?

Ubuntu Multimedia :: App For Working With Audio CD Images?

Feb 15, 2010

Is there a Linux app for mounting and playing audio CDs from image files? I have saved disc images of nearly all of my CD collection, but I have yet to find any convenient way to play them.

Because of the nature of CD audio, every CD image has an accompanying .cue file, so there are actually 2 files (*.iso or *.bin and *.cue) from each disc. VLC Media Player will play DVD .iso images directly, but doesn't know what to do with audio CD images (or the .cue files).

Mounting and unmounting the images at the command line is tedious, given the very long file paths. I'd rather have a GUI-based app. Does any such thing exist for Linux?

FWIW, Acetone ISO doesn't work. It doesn't want to mount my *.iso format CD images. Probably some funkiness of the CD audio format. I think it is what the Acetone devs call a "multi-sector image." Likewise for the *.bin images of CDs.

Ubuntu Multimedia :: MKV Files Audio/video Out Of Sync?

Mar 29, 2011

I put all my dvds on my "media center" by converting them to .MP4 with handbrake.

Recently I saw that with a MKV file you could do soft subtitles. I tested a part of a movie, and the audio and video are very out of sync.

With MP4/burned in audio everything is ok...

Edit: Ow yes I'm using XBMC for playing it. MP4 + MKV files are both H.264, they have the exact same settings except for subtitles...

Weirdly Enough: I tried another video and at this one the audio is in sync....

Ubuntu Multimedia :: Audio Out Of Sync After Creating .iso Using Brasero With Version 10.04

Jan 5, 2011

I am attempting to backup DVDs that I own to .iso format so that I'm able to watch them using xbox media center. I've simply been copying the entire DVD to my HD in .iso using brasero.When I watch the .iso file in XBMC, the audio is a fraction of a second ahead of the video. The gap between the audio and video doesn't seem to change over the duration of the clip.

What are the likely causes of this issue? I've read that it could be a slow processor, little ram, or inadequate video card. If it's indeed a hardware issue, I suppose I'm SOL with my current laptop: a 2006 dell with a core 2 duo processor, 2GB ram, and a middle of the road video card at that time.Is there any software tweak I can explore to get the .iso file to sync properly?Also, I know it's customary for posters to list their system specifications, but I don't know how to call up my software or hardware setups.

Debian Multimedia :: Avconv Gives Audio And Video Out Of Sync

Sep 10, 2015

I have a problem with avconv. Most of the use cases work spledidly, but when I need to crop a segment and then splice multiple segments together, I get problems.

The process I use is this:

1. Raw recording of short segments in high-quality AVI, These are produced by avconv, some as screencast and some by combining a PNG file with flac audio from audacity.

2. Conversion segment by segment into mp4 and ogv
Options A: -acodec aac -strict experimental -ab 128k -ac 2 -vcodec libx264 -s 640x480 -pix_fmt yuv420p -movflags +faststart -crf 22
Options B: -acodec libvorbis -ab 128k -ac 2 -vcodec libtheora -s 640x480 -b 500k

3. Splicing of the segments using MP4Box or oggCat.
(I used to do this in ffmpeg, but I have not figured out how to do it in avconv.)
This works.

In some cases I need to crop the segments, using the copy codecs and the -ss and/or =t options.

If I crop the AVI segments (between 1 and 2) the sound is clipping (this also generates a spree of error messages `Non-monotonous DTS'). If I crop mp4/ogv segments, (between 2 and 3) the remaining video, after the cropped segment are out of sync. I get the same problems with both OGV and MP4 playing them in vlc. Playing the mp4 directly in iceweasel works as it should.

Debian Multimedia :: VLC Stream Capture Audio Out Of Sync

Oct 20, 2015

So I got myself a USB capture card (EasyCap) to use for capturing gaming, digitizing my kids' old VHS movies, etc. It works fine, I've been using VLC to view and record stuff from it, but I've noticed one issue. When recording streams via VLC, even with no other programs running to give VLC as much CPU time as it wants, the audio slowly falls out of sync. I've tried the MP4 (H264/MP3) container and the OGG (Vorbis/Theora) container.

Early on you can't hardly tell, but the further into a movie you get the more out of sync the audio gets, so that by the end of the movie the audio is a good 1-2 seconds off. It's not a set amount either so I can't just split the audio to a separate file then shift it one direction or the other to make up for the difference, because like I said, the offset starts out at nothing and gets progressively larger as the movie goes on. When I select "display locally", the video/audio that is displayed stays in sync, only the video/audio that gets committed to the output file falls out of sync, and it doesn't matter if I play the file with Totem or VLC.

Ubuntu Multimedia :: Losing Audio Sync When Editing Video In Openshot

Aug 31, 2010

my goal is to record video using a canon powershot camera, edit the avi file on my ubuntu 10.04 computer, then upload the rendered file to videos.

problem is that when i cut the video, the audio is no longer in sync with the video, it's off by about 1-2 seconds. this happens with both openshot and pitivi, so i suspect that it's caused by a bug with the codec. (files are avi with mjpeg codec). after searching launchpad, this is apparently a "known issue". that's great but for now i need a workaround.

i do have an old g4 powerbook with imovie hd v6 on it that i can use, but i'd prefer not to because:

1. the powerpc mac is much slower than my new dual core laptop
2. imovie compresses my videos too much so the rendered file is lower quality
3. i simply prefer openshot to imovie

i was thinking of preprocessing my avi files by converting them to another format with a non-buggy codec on linux. i downloaded ffmpeg, but not sure how to use it and what format to use. would mpeg2 be a safe one to use?

Fedora :: Mencoder - FPS And Audio Sync

Nov 22, 2009

I have found that if I change the FPS of a video, the audio is out of sync.

Is there a way in mencoder to have it correct this, and maintain the correct sync?

I don't think it is just a matter of audio/video delay. I have tried many times to correct this via that method, and it doesn't come close. Although, if I encode the video to another format, but with the original fps, the audio is sync'd.

Fedora :: Audio Out Of Sync In VLC And Others But Not Totem

Jul 24, 2011

V.L.C. and all others - but Totem - video players that I have installed have audio out of sync. This occurs in both D.V.D. and .mkv & .avi. I had this problem with V.L.C. 1.1.10 & now with 1.1.11. I do not think that this is a problem with V.L.C. since I have had the same issue occur with gnome-mplayer. I tried to downgrade gstreamer*, and that did not correct my problem. It shouldn't be a problem with libdvd* since the problem still occurs with files on my drive. Handbrake doesn't fail to rip D.V.D correctly.

Because of all of this I figure that it must be a system library that Totem and HandBrake don't use ( or bundle most likely in the case of HandBrake ).I am using Fedora 15 x86_64 with all updates to date.
