Sound and video streaming problem

My iPad has an intermittent issue, where the sound/clicker doesn't work, and video and music streaming doesn't work, or constantl plays-then the sond stops and streaming stops! Trying to press the volume buttons doesnt help as the volume icon doesn't appear straight away. Usually nothing happens when they are pressed.
However, all is fine when the iPad is charging!
I've tried updating and going back different iPad software versions, resetting the device. Now I am fully discharging the battery to see if a full charge up helps.
Anyone having similar problems , or suggestions to get this sorted?

Sound and video problems?

ok here is the deal, i got all the latest drivers for my system.
i got the
MSI 875P NEO LSR mainboard
p4 3 ghz with HT
with 1024mb ram
160 gb s-ata
geforce fx 5600 XT/256 mb
soundblaster live 5.1 sound
when i play heavy games like HALO or Need for speed my sounds and video works not correct BUT it should not be a problem because my amd 1800+ with gforce ti 4200 did better
i think it's the mainboard but does ANYONE has an solution or the same problem?
o yeah my system reboots sometimes when i put new hardware on it (had it with my USB modem 4 ADSL)

This sounds like it is your PSU giving troubles. What wattage is your PSU, and what are the 3.3v, 5v and 12v ratings on the PSU? (You can find out this info on the sticker that is attached to the PSU)

When exporting separate audio and video streams, the audio drifts out of sync

So this is my first slightly larger project in Final Cut Pro X.
When I export my finished project (around 12 minutes long) straight to quicktime, it plays back perfectly.
When I export using compressor, the resulting audio and video streams are two different lengths. The audio comes out a full second longer. If you try to lay them down in a program like Adobe Encore, the audio starts out perfectly in sync. Two minutes in you notice the video is slightly out of sync with the audio. By the end of the video it's comically bad, over a second out of sync.
What's even more vexing is if I try to take the quicktime file that IS in sync upon playback, and try to convert it burn that to a dvd or blu-ray using toast, the problem re-emerges.
I triec searching around, but most of the suggestions that came up were vauge, like, "Upgrade to a real program like Final Cut." (This was in reply to people who were using free software programs.)
I did see one idea surface where 44 and 48 kHz sampling rates don't play well together. So I combed through my project and found all the 44.1 songs that were used, and swapped them out with upsampled versions. Nothing changed. It didn't sound like it would fix it, as people usually said it was a specific amount of frames off, not something drifting out of sync.
So the question is, does anyone have any suggestions on what could be causing this? Thanks! :-)

Project settings can be accessed and changed by selecting the project and pressing command-J. Then, in the inspector, click on the little gear in the lower-right hand corner to access the settings.
Why are you trying to output video/audio separately? If the content plays in-sync when exporting a quicktime movie (using current project settings), you could try separating the video/audio using MPEG Streamclip as a second step instead of using compressor. For audio, don't change the sample rate from the project settings, and use uncompressed audio (AIFF) as the output format.

Mismatch between sound and video

When I watch a movie in iTunes of Apple TV (2gen) and I want to move it few seconds/ minutes and more backwards then it like "losing its mind",
the video jumps forward (a lot forward) and the sound stays the same, so ther is mismatchment between sound and video.
What can i do to solve this problem?
Thank you!

Am I the only one suffering this issue with the video transcoding?

[Python pygame] Graphic equalizer - keeping sound and video in sync

Hi!
I'm writing a graphic equalizer in python and I want to use pygame for the video and audio output.
The video display of the moving bars works great, now that I have a correct way to read samples and decode them.
The problem now is: they're way out of sync with the audio playing in the background!
At the moment my code, that draws the bars basically looks like this:
# loop as long as we can get slice of the audio file for the fft
for n_frame in range(0, len(framebuffer), fftframesz):
clock.tick_busy_loop(t_loop)
# t_loop was defined as fftframesz over total_frame_count
# which means in words: t_loop is the amount of FFTs per second - or the cycles of THIS loop
# grab the frames and perform the fft here
...numpy.fft.fft...
# set the new bar heights and draw them
for bar in bars:
bar.update()
# if playback has not started yet, make it so
if not pygame.mixer.get_busy():
musicfile.play()
The way I'm thinking, this should be enough to keep sound and video in sync. Because we know the time that one cycle should take at most,
we can set the clock to tick_busy_loop this time. This way we make sure that the video is not faster than the sound.
But to me it seems that is is the other way round, i.e. that the video is slower than the sound. I already did some timing, but to no avail.
Is there perhaps a more easy, more elegant way to make sure that image and audio are in sync?
Any help is greatly appreciated!

Thanks for your ideas. I assume you mean I should go with a $1200.00 final cut pro software. NOT.
Sure the video will be on myspace and youtube but wether they are noticed or not is not as important as self satisfaction. I can easily split scenes into equal time zones as I said. Then drag them into clips and back all using the same camcorder. Multiple cameras and angles would be nice but this can be done on a low budget and still look good. I guess my original questions were not answered. Is there a way to determine the length of a transition and shorten the clip by that amount. Or the length of a still shot and do the same. Or perhaps they have been answered and the answer is NO WAY, and I am just not hearing it.
I suppose reimporting a video would be great if I could use two timelines like in audio and then blank out what I don't want in the first. But I just don't think this is possible, or is it. I've been reading iMovie HD6 The Manual that should have been in the box. It's a help but doesn't take you from the beginning of a project to the final project. Exporting to imovie or idvd is not an issue. BTW I got the clips in sync as I said by leaving blank spots and placing effects over them. I could insert the proper length video in those spots but that can look silly without transitions. But then again so can transitions. This stuff is very fun and interesting and a great learning experience. If I stop now as you suggest then I am not pushing myself to the limit. But thanks for your reply.

Sound and video are choppy since installing Flash Player 11.3

I'm having a problem here! Since I updated Adobe Flash Player 11.3, the audio and video are all choppy when I play Adobe Flash game apps in Facebook! Even when I disabled hardware acceleration, the sound and video are STILL choppy! Even I watch a YouTube video and the sound and video are a bit choppy! There's DEFINITELY some sound issues in Flash Player 11.3! I'm using Firefox 13 in Windows XP SP3. I'm wondering if you have any answers for the sound issues in FP 11.3.

I went through an annoying password reset process to post on here, haha, I was experiencing this issue and managed to resolve it for a flash animation I was making that was going to be sent out; thus fixing it for myself wouldn't change things for others. I know this is old, but if anyone is in this position, I hope it helps.
I was using Swish Max for my scenario.
Under the Export Settings, I found that by default it was using SWF Version: SWF8 - when it had the option to go up to SWF10. I changed it to 10, and set the hardware acceleration to Level 1 - Direct.
I exported, and it still didn't work. The music was choppy as heck and terribly inconsistent with speed. I even created a preloader, which appeared to work but didn't resolve my issue.
FINALLY, I kept it at version 10, and found that it had an option that said "Preload Content: Disabled." I set that to "At Preload Frame" and though I had a loading animation setup to do the preloading, I still placed a preloadcontent keyframe at frame 1. Then I set Hardware acceleration to Level 2-GPU and exported.
IT WORKED. The terrible, seemingly non-fixable audio cracking lag was gone and it worked flawlessly.
Hope this helps someone, I originally found this when I was trying to find a fix for the issue.

Equium-A100-147 - broken sound and video

Hi everyone,
I have the Equium A100-147, Its been working fine for last couple of year.
But in the last few weeks has get problem in sound and video (broken sound and video).
The sound is breaking and sometimes uable to listen + video breaking and so much delay due to its get so slow with so much sound distorsion etc..
This remains after new installation (format HDD) of Wind XP unable to fix even installed new drivers.
The Device Manager shows all drivers including audio and video working ok, d'nt know what's problem please help me.
Thanks.

Hi
Something like that can happen during high HDD activity this means that the reading/writing process could affect the sound/video playback
But usually this should not take long time
At the other hand this can happen because of higher temperature
High temperature can affect the CPU and GPU performance
I think you have used this notebook for couple of month without any troubles in my opinion you should check if cooling modules and fans are clogged and could remove the dust and debris from cooling modules use compressed air spray this helps p get rid of dust
Maybe then the notebook will run much better

How to demultiplex the merged audio and video streams

Hi. I'm currently working on a video conferencing program. I successfully implemented the program using threads to run the audio and the video clients and servers. The problem with this is that the delay for the transmission of both media is a little too great. So now, I'm trying to merge both media into on DataSource, so then I don't have to worry about sending audio and video into 2 different ports and RTP sessions. I know how to merge the audio and video streams, but I was wondering how to extract each media back after receiving the merged audio and video streams. Any ideas? I used the createMergingDataSource(the_DataSource_array) method to merge both streams. Thanks.
J.L.

I am working on the same problem. Is there any solution yet?

I am programming the videoconference program using Java Media Framework API. I use two session to transmint and recieve the media, one for audio and one for video. Two players are opened to play both media. I would like to know if I can play both media using only one window.

Onboard sound and video IRQ prob

Well I have norrowed down a prob I believe is with the sound and Video using the same IRQ.
Both are using irq 16...
Why windows would put them on the same irq is beyond me.
Is their a way to change this?
Mobo is KT4 ultra with c-media sound
video is geforce4 ti 4200
System keeps rebooting when in games.
I just did a fresh install and installed drivers and bleh same thing.
I also turned off plug and play in bios. which microsoft recommends.
Any help would be great
r00t 3:16

Well considering their is a alot of IRQ's and half of them aren't in use you would think ms would not assign a video and sound to the same irq.....
At any rate. Im not sure what games you play but most games check to see if your sound card is working before it loads.
So that won't work.
I didn't have any problem with this system until I formated and redid everything I should of just stayed with it as it was.
Then the sound was on irq 16 and the video went to irq 128?
Thats right 128....
I didn't have to disable APIC either.
Although I did however have plug n play support disabled in the bios.
I also installed all drivers and devices before I added the service pack.
Maybe ill just get a different sound card.
Who knows.
But at any rate IRQ 5 is reserved for sound cards from what I read online. Unless you have a SB series they like irq's 7 or 9....
Anyways ill let everyone know what I did then.

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

Can a MacBook (Early 2008) Support both sound and video to 1080p HDTV by Mini-DVI to HDMI cable?

The mini dvi on the MacBook will only support video, in order to get audio you'll need to a cable from the sound out port to the sound in port on the TV.

How do you get sound and video from a macbook pro (before 2010) onto a 2010 toshiba 40" tv?

Any help on connecting a macbook pro (late 2009) to a 2010 toshiba 40" for both sound and video? I have the mini-hdmi cable, but have no idea about running sound through the tv. I can use the headphone jack, but don't know where to connect it to on the back of the tv. Am I supposed to change any settings on the tv or computer to allow the sound to go through the tv? thanks for any help.

You need a stereo mini to RCA break out cable.

Loss of sound and video playback on ENVY X2

Every so often, more often than I would like, my HP Envy X2 loses sound and video playback capabilities; any ideas anybody? The concept of this machine is great and have had it for the past 9 months but this loss of sound and vision is so unpredictable and frustating...

Hi Brumage,
I saw your post regarding the sound and video issues and I will be happy to help. Do you get any error messages when this happens? Have noticed if it is a particular site like YouTube or program that you are using when the issue occurs or does it occur on all programs? When you restarted the Envy X2 does the issue go away?
I would start by suggesting that you make sure all updates have been installed through HP Support Assistant and Windows Update.
What operating system are you running? What is your product number?

Why is live and video streaming so slow on my MacBook Pro?

why is live and video streaming so slow on my MacBook Pro?

Hi redngreen,
Does this happen with Wi-Fi and ethernet?
Is your network slow with other activities?
There's a section in this article for Wi-Fi network seems slow. Some of it applies to Ethernet as well.
