my vlc player suddenly decided to start de-syncing my sound and video. Switching vlc to asla output corrects this, but also makes the player go mute whenever you pause and resume a video. Totem is still working fine, but I really like vlc.
View 9 RepliesWhen I play large HD videos in mplayer, the video and sound frequently get out of sync, and the video plays a little strangely (occasionally speeding up and occasionally slowing down).
I think it's because mplayer is only running on a single core. As I've got a quad-core processor, it seems inefficient. I've seen that there is theoretically a way to get mplayer to work with multicore setups, but it requires compiling with different options. That'd take me a little while to work through.
Ideally there would be a pre-compiled version in the software centre, or a player which has support built in (again, ideally in the software centre). Is there such a thing available?
I just upgraded to 10.04 and now my video and sound is all out of sync and video is choppy. What can i do to fix this?

View 1 Replies View RelatedIn the last week, whenever I play videos, online or offline, the sound and video are out of sync. Usually the sound is a full second behind the videos, but I've noticed it at less.
I just tried watching a video and whenever someone said something, the sound was a full word behind the movement of the mouth.
This never happened until recently. I think there was an update to the sound drivers a couple weeks back, but I'm not too sure.
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.
I watch alot of news videos and within 1 - 2 minutes the video and audio become out of sync. The video is lagging the audio. I'm using 10.10 32 bit with Shock Flash 10.1 r102 on Firefox. Will the 10.2 beta flash fix this problem?

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....
After upgrading to 11.04, video and audio are out of sync by about one second when playing movies in VLC, or opening a clip on the web. Reinstalling does nothing.

I have a couple of .avi clips in which the sound plays 2 seconds before the video, so I need a software that can re-sync the sound correctly with the video with affecting the video/audio quality, what program can I use?

View 3 Replies View Relatedmy 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?
I recently purchased a new motherboard and processor to replace an existing system. I transferred the video card. OS remains the same, Ubuntu 10.10 x64. Video worked fine in the first system (eVGA motherboard, Intel E6600 CPU, 4GB RAM), but the old motherboard had a SATA controller issue. New system: Gigabyte GA-890FXA-UD5, AMD Phenom II X4 955 Black Edition Deneb, 8GB RAM
Transferred hardware:
Graphics: eVGA nVidia 8800GT,
Monitor 0: Hanns-G JW199D 1440x900@60Hz
Monitor 1: Gateway FPD1975W 1440x900@60Hz
The Problem:
1. Fresh OS install, everything starts up as expected, login, etc.
2. I use the Additional Drivers link from the menu and select the recommended nVidia driver and enable it.
3. After reboot, the following things happen:
3a. BIOS
3b. Ubuntu startup scripts
3c. Ubuntu logo with spinning dots
3d. Monitor goes black
3e. Monitor notifies it has lost sync
I believe 3d is where I would normally get the login dialog. I can use failsafe mode, but everything I've tried to fix the graphics display hasn't worked. I've even tried to load the latest nVidia driver, nvidia-config, nvidia-settings, etc. There are some options I've tried where the nvidia-x command returns "can't find device". I've tried to modify the xorg.conf file, to no success.
Any ideas what I can do to resolve the error? I'm not that strong on the xorg.conf file, but all I've read is that it's not too necessary anymore. Though, it was modified in my old system to get Twinview working. I've looked through a bunch of log files, but I may not have been looking in the correct log file.
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.

This problem can occur during capture from an analog capture card if CPU utilization exceeds 95 percent. To avoid this problem, configure virtual memory to be "System managed" by following these steps:
1. Choose Start -> Control Panel.
2. Open the System control panel.
3. Click the Advanced tab.
4. Click the Advanced tab.
5. In the Virtual memory box, click Change.
6. Select System managed size, and click Set.
7. Click OK.

I use jpilot on opensuse 11.3 64bit to sync pim data with my Palm Treo 680 via bluetooth. This worked fine until today. Now I get the following error message when I try to sync: Syncing on device bt: Press the HotSync button now dlp_ReadSysInfo error Exiting with status YNC_ERROR_PI_CONNECT Finished.
The last successfull sync was on the 20th October and today is the 24th October. I did not change any settings in jpilot or on my palm device. So I guess there must have been an update of opensuse which causes this error. But I do not now how to look up the updates during this period or how to undo them. Was there an update between the 20th and the 24th Oktober, which might affect either jpilot or bluetooth functionality?
