Synchronize audio and video over RTP

Hi all,
I am new in jmf. Please any one tell me, how to synchronize audio and video streams, when we capture thru audio and video capture devices and send it over network thru rtp protocol and receive at client side. How to syncnronize at client side? Please send me reply if any one have solution in jmf.
Thanks in advance.

Does anyone know about how this is done? I'm doing a videoconference thing with jmf, QoS is a required componenet! So if anyone knows about how this is done, plz share with discussion! All I know so far is that I can buffer the incoming streams to some extend then call syncStart() to start the video with the starting time of the video!

How to synchronize audio and video rtp-streams

Hi everyone!
I've tried to make one of the processors, processor1, control the other processor, processor2, with processor1.addController(processor2) but I get a
javax.media.IncompatibleTimeBaseException. I need to synchronize audio and video rtp-streams because they are sometimes completely out of sync.
In JMF API Guide I've read:
"2. Determine which Player object's time base is going to be used to drive
the other Player objects and set the time base for the synchronized
Player objects. Not all Player objects can assume a new time base.
For example, if one of the Player objects you want to synchronize has
a *push-data-source*, that Player object's time base must be used to
drive the other Player objects."
I'm using a custom AVReceive3 to receive rtp-streams and then I create processors for the incoming stream's datasource's, and they are ALL PushBufferDataSource's.
Does this mean I can't synchronize these. If so is there any way I can change them into Pull...DataSources ?
How are you supposed to sync audio and video if not with as above ?

You can't change the timebase on an RTP stream because, for all intensive purposes, it's "live" data. It plays at the speed the transmitting RTP server wants it to play, and it never gets behind because it drops out of order and old data packets.
If your RTP streams aren't synced correctly on the receiving end, it means they aren't being synced on the transmitting end...so you should look into the other side of the equation.

How to synchronize audio and video

Hello,
I have an application that stream video images. Whats going on at the other end( the audio) I can also stream that.
Now i want to synchronize both audio and video for effective synchronized output.
Can i do that. I dont know the API that are available in Doja. Is Any timebase or timesynchronize APIs are available through which i can synchronize both.
Any Suggestions and ideas can be implemented.
Thanks

I know that In Midlet development using MMAPI there are APIs available to synronize the players like
p1.setTimaBase(p2.getTimeBase())
But I am not using Players. Through http connection I m getting the raw image data and displaying it through ImageItem i.e no players required.
Therefore If i stream the audio like this How to synchronize that.
I relly need ur Help
Thanks

VLC - audio and video over aiplay

I tried using airplay mirrorring from my Mac running VLC to my AppleTV to watch on the computer. However I see that the audio from the VLC app still plays through the desktop and not the TV. If I increase/decrease volume, that is heard on the TV but the actual movie audio is heard only on the mac. It i like the movie audio is sent to the mac speaker source instead of airplay. What am I missing?

Maybe this...

Audio and video out of synchronization in iTune for Windows 8.1

When playing back a downloaded iTunes file, the audio and video are out of synchronization a lot of the time. The audio can be several seconds behind the video.
How can this be corrected/fixed?
I am running the latest iTunes software on a 3.8Ghz AMD-processor machine running Windows 8.1.

Hi John,
Welcome to Apple Support Communities.
Take a look at the article linked below, it provides a lot of great troubleshooting tips that you can try, which will resolve most video playback issues in iTunes.

Audio and video cpompression over anetwork.

Hello every body,,
I want to transmit audio and vedio over internet,, and as every body know the transmition of audio and vedio has some delay over the internet...
so can i made some compression to audio and vedio streams at the sender side and then transmit them and extract this commpression at the receiver side..???

i dont think you can compress to a lower quality when sending and then decompress to a higer quality when receiving. actually, h263 and jpeg are already compressed. what you can do is just degrade the quality of a jpeg or h263 streams and receive it like that. the lowest one-way video stream bandwidth i could go down to w/o major programming was 80-90kbps with h263 codec. there's probably a way to make it even less, but it requires a deeper programming to reduce frame rate, because standard JMF ways to alter frame rate dont work (i've tried at least 3 different ways). if you can do it, you can probably get a decent quality one-way video stream with as low as 30kbps

How to synchronize multiple, unorganized audio- and video clips

I'm editing a video with audio recorded by an external recorder.
I've been given a lot of unorganized files and I wonder if there's a quick way to synchronize them all without knowing which audio- and video file that fit together.

I've been pretty amazed by how well the synchronize clips command works. You might take a chance and select all of your audio/video files at once, right click and choose Synchronize Clips.

Audio and Video Synchronization

Is it possible to have a synchronized audio and video on a video conferencing application running on jmf? Doing this project has led to discoveries that audio is slower than video to transmit. And what video formats should be used on audio and video to have synchronized. If ever someone has got synchronized can u please email it to me [email protected] Thanks. :)

Hi,
The videos are small: 3 to 5 minutes, maximum.
However, I think I know what the problem is. When captivate
build the project it converts avi to mp3. In this process it uses
the configured options of the audio file, including the bitrate
option. The problem is that the mp3 bitrate will be different from
the avi bitrate, and they should be equal.
Despite that I couldn´t solve this problem, because
captivate and the other product I´n using "DubIt" seems to
have incompatible bitrates! I can´t get an equivalent bitrate
to both products?
Does anyone use Dubit and know how to get an equivalent
bitrate in both products? In captivate we can configure a custom
bitrate but the choices are still limited.
Thank you

Can i take both Receveing of audio and video on the same window.

hi,
i m using AVTransmit2 and AVReceive2 for Transmission and Receiving all is doing well but problem is that AVReceive2 show Transmission of audio and video in both different windows and it use different players for audio and video. Can u tell me can i merge both audio and video at the receiving end. i m already mergeing audio and video at transmission end ???. any one tell me how can i solve this problem ???
thx in advance.

Hi,
I have the same situation - to use one window to show both rtp audio and video stream, but use the ControlPanelComponent of audio player to control both players.
I want to use the audio player as the master player so that the video player could be synchronized with it. So: audioPlayer.addController(videoPlayer).
In the only window frame for both players, I want to show the VisualComponent(VC) of video and the ControlPanelComponent(CC) of audio. So I add both components respectly to the window frame, after I got them from each player. Because the streams are coming from the network over RTP, and they do not become realized at the same time, I add the VC and CC of first realized player(no matter it is audio or video) to window frame at first, and then change them to the desired video VC and audio audio CC.
Though I check both player are realized and not started before I call the addController() method, the application stucked in this method. Of course I call it in a try block but no exception was thrown out.
when I use TimeBase to synchronize them, i.e., videoPlayer.setTimeBase(audioPlayer.getTimeBase()), everything goes fine. But, I can not control both players from one ControlPanelComponent in this way.
Anybody having any idea to solve this problem please reply.
By the way, in the example code such as AVReceiver, where audo and video streams are shown on two window seperately, user can use the ControlPanelComponent of audio to control both player, though it seems no relevant code to support that function. The ControlPanelComponent of video can not control the audio player anyway. Anyone having any explanation to this?

How to stream audio and video captured from mic and webcam in sync.

I am working on a video chat project. I need to capture audio and video from mic and webcam and create rtp stream for them. How can I proceed for this. Any source code help will be highly appreciated. Otherwise just guide me how to do this and point to any good resource which is directly related to my need.
Thanx.

t.b.m
As mentioned by you, i am doing exactly like that . I have coded transmitter class. But at the receiver side it is unable to play the stream. I am posting my code . Can you please help with me with any mistake i m making in my code ?? Or with way I should receive stream at receiver side. Plz see my code. I am streaming to ip address 172.31.80.67.

DO i need some extra hardware interface for receving both Audio and video

hi i m doing e-learning project. i have to capture video from webcam and voice from headphone and send to client.
but my code is working fine for either one at a time.
DO i need some extra hardware interface for receving both Audio and video. im using code AVTransmit and AVReceive found from this site only
After running TX
i give Dsound:// & vfw://0 in Media Locater only sound is received and no vedio
and when i give vfw://0 in Media Locater only live video is transmited.
im using JMF1.1.2e.
if any one know the method to run or cause of it plz reply me soon. i will be very thankfull
transmiter/server side code .first run TX on server

I do this all the time, I put my MBP to a 60 inch Sharp. If you have the video working do the simple thing first. Check to make sure your sound is on your TV and Mac. Then if that doesn't work go to System Prefrences and under sound go to a tab called Output and see if your TV is listed and if it is change it to that setting
Hope It Works

Does 2 firewire audio and video interface can work together on FCP ?

hello,
My audio interface is a TC Electronic Konnekt 24D
my video interface is a Canopus ADVC 110
my hard drives are plugged in firewire too
and I use Final Cut Pro 5.0.4
So, the konnekt is recognized by FCP only when the Canopus is not plugged. And even then, the audio sometimes drop out and sometimes causes the app to crash, so that I have to trash the preferences
When I plug the Canopus, the Konnekt 24D is recognised by OS X but not FCP
I want to use the voice over tool with the konnekt 24D, so what should I do ?
Does 2 firewire audio and video interface can work together ?
If so, maybe I only have a driver problem from TC Electronic.
But if not, I have to change this interface. Let me know if only RME, MOTU, Presonus and Edirol work, as it is said on apple's webpage for hardware compatibility
thanks

The 1082 does show up as a possible input when I open
the VO tool.
Ok. So an audio interface can be plugged to FCP without crashing the app. Because of the Konnekt driver problem, I wasn't shure of this.
I use my Aja box for export & external monitoring.
All my audio sources run back into the Tascam and I
use the analog mixer in the 1082 to monitor different
sources.
When I view external video, the audio follows it to
keep sync.
that's exactly what I want with other I/O interfaces. I'd like to monitor video with the canopus ADVC 110, and monitor audio with the Konnekt 24D (or another interface if this one is not compatible)
I also imput dailies with a deck or a camera (DV or HDV) but that's not the point here.
I want to imput audio with the Konnekt 24D because of its audio quality. Not audio sync to video dailies. But voice over, in sync with FCP video playback (for me, tha ADVC 110)

I am trying to export a video from Premiere Pro. I have both audio and video checked and the sequence is active but only the audio exports. There is no video at all. Can anyone tell me how to get the video to export. It was working fine until today.

Premiere Pro CC has been working fine until today. I have completed my sequence and it is active. I have both audio and video checked when I am exporting using H.264 with Match Source Hi bitrate. I am choosing entire sequence. The audio exports but the video and title does not. Can anyone tell me how to troubleshoot this so I can complete this project? Please!

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

Photo Booth Audio and Video not in sync!

I am a YouTube musician. When I go to record I find it easiest to use the video feature in Photo Booth. However, ever since I upgraded to Mountain Lion my audio and video in my videos has been off of one another. They start off together but by the end of the video the audio is ahead of the video. When I went to try and see where it messes up I found that the video jumps frames creating almost a transition effect. I don't know how to fix this and would really like your help!

Audio and video out of sync after import

I'm trying to bring some H.264 video into a Premiere project. But when I place it in a sequence (a sequence that is created based upon this very clip), the audio and video are about a second out of sync. (It's also odd: no amount of adjustment will bring them in sync. Seemingly the video is running at some variable rate that makes synchronization impossible...?)
As a test, I tried bringing my video into iMovie, and it works just fine there. But I don't want to use iMovie: I want to use Premiere.
Any ideas?

Thanks. Here's the output:
