How to transmit audio and video simultaneously?

Hi,
I am new at jmf.Now i have a problem that how to transmit audio and video at the same time.The AVTransmit can transmit only one media,audio or video.Anybody have experience with it?Please help me.Thanks a lot!

Hi, audio and video data must be transmitted in 2 distinct RTP sessions, by using different ports at sender side.
At receiver side, the port can be only 1.

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.

Satellite A80: How to restore audio and video codecs?

How can I restore the audio and video codecs which are installed by default on my Satellite A80 with XP Home edition?
I removed them in safe mode because of a problem with the Pinnacle Codec installed by Pinnacle Studio 10.
Now I need to set the standard audio en video codecs back.
I already downloaded the codec package from Microsoft Mediaplayer and have sound en video again in Media Player.
Unfortunately I still don't have sound in Toshiba Diagnose Program when testing Midi and Wave sound.
System restore came up with the message that restore was not possible because no changes had been made.
Message was edited by: roel

Have investigated in the forum and found this different codecs:
-Zsunami Filter Pack: (3.9.9)
- Nimo Codec Pack: (5.0 Final)
- ACE Mega CoDeC Pack: (5.93)
- Codec Pack Elisoft: (13.505)
- K-Lite Codec Pack: (2.2) Full
- SLD Codec Pack: (1.5 Pro)
- All in One: (5.0.6.1)
- The Codecs: (1.1 full)
Well, if the system restore does't work try to install one or several codecs from this list.
Have found it in this posting:

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

Record Audio and Video Simultaneously.

Hey,
So I have Quicktime pro and I know how to record a video using my built in camera on the imac.
I also have logic and am more than capable of recording through various input devices such as mics, keyboards and guitars.
But how can I record a video of myself and audio input, such as a mic/me talking/whatever at the same time?
I'm using a digidesign Mbox 2 for my audio input.
Thanks

What happens when you set your inputs properly and record a clip in, say, PhotoBooth? Do you get audio and video? It should be pretty much as straightforward as that.

How to get audio and video in one file

hi...I am "premiere beginner user" and I have a simple question , I think..:)...Every time when I am trying to export media out from my premiere (using media encoder) I get video file and some audio files, but what I need is only ONE file, that contains both (audio and video)..for example , I have edited film in hd quality and I want it to export, I choose h.264 format(make some settings,pal,audio quality...) and when it´s "all done", only "result" I get is one video file and two audio files and they are not together :).....so please help mme anyone..ok and as you can see I am not from english speaking country, so sorry for my english...thanks for help....

There is no indication that something is out-of-sync or the ability to move/slip into sync like in FCE/FCP.
To the best of my knowledge, using match frame and overwriting the video with video+audio (or attaching it as a connected clip if you don't want to overwrite the video, which might have effects applied) is the best way to do this.
You can use the blade tool first in the timeline to get just the section you want to get back into sync. Make cuts so that you have a single clip that needs the audio resynced, select it, and use shift-F to select the original synced clip in the Event Browser. Make sure your play head is at the beginning of this video clip in the timeline. Press option-2, then 'q', and now you have the audio back in your timeline, synced with the video. Delete the old, no-longer-synced audio and you should be set.

I'm trying to record audio and video simultaneously using iMovie and an external mic and the computer is picking up the audio but when I replay the video there is no sound. Any ideas?

Can't get iMovie to record audio and video at the same time using the built in cam and an external mic.

iMovie works best with uncompressed audio. If your track is MP3 or AAC, you may get better results by converting your track to the AIFF format and then using that in iMovie.
You can do this in iTunes. Go to iTunes/Preferences and click the General button. On the General page, click the Import Settings button. Choose IMPORT USING: AIFF ENCODER.
(note: remember what you changed it from so you can change it back later, before you import another CD)
Now, in iTunes, select your track. Then click FILE/CREATE NEW VERSION/AIFF VERSION.

How to apply audio and video transitions automatically when drop multiple clips to timeline?

If I remember OK, in previos versions of Premiere it was possible to Drag multiple Clips from project area to timeline, and apply automatically audio/video transitions.
It was possible to configure how many video frames will be overlapped to do a default transitions (and for audio, also).
Is it possible in Premiere CS6 to do the same thing ? Leave me a link to documentation, or a hint, how to get this thing done.
I have searched over the documentation, but i have not found.
Thanks for hints.

I believe the feature you're referring to is Automate to Sequence. In CS6, it was in the Project Menu; for those using CC, it is in the Clip Menu.

Syncing Audio and Video but wish for the Audio not to move on timeline?

Has anyone worked out how to sync audio and video within Premiere Pro but have the Audio stay fixed on the timeline and the video move? Every way I try it Premiere Pro insists on moving the audio. Locking the track does not work as you cannot select the audio within it to Sync with.
I have a music video shoot with 14 camera angles used on the lead singer (don't ask me why). Multi-camera editing is not an option as there are too many sources for my brand new MacbookPro to handle. I think I would need the computer from Superman II to edit that many clips together.
What I am doing is syncing the first clip, the one Im going to use as the baseline fall back shot and then I need to sync other clips onto the timeline. However Premiere Pro insists on moving the audio to fit with the video not visa-versa.
Any help would be appreciated.

@slitchfield: on the mentioned page, it is stated that "Improvements in screen real estate, with slimmer top status bar and optional (in some apps) bottom toolbar, meaning that all phones will have a larger useful display area."
But on the E6 the bottom toolbar decreases available screen size in most apps, most noticeable in Web browser where the full view has gone. The bottom toolbar is not optional, you can't configure it yourself.
And: "Homescreen widgets will now come in up to five different sizes (1x1, 2x1, 4x1, 2x2, 4x4) and allow a greater degree of interactivity.", but on the E6 they are in only one size, always with large borders and other visual effects.
So beware of differences between phones, perhaps some aspects of Belle work differently depending on the type of device.
"Notes now brings up a white (and AMOLED-unfriendly...) editing screen.": that you can change by switching themes, "Dark Solid for Anna" does a good job. It is a shame that the lines of Notes have gone though.
When switching themes, I found you have to restart the phone, otherwise the theme doesn't get properly loaded in all apps. Stopping/starting apps is not enough. So when experimenting and loading one theme after another, you may end up with disfunctional combinations of black-on-black and white-on-white, but it may not be due to the last theme. Also you may end up with a good combination that isn't around anymore the next time you restart your phone.

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!

Separate audio and video feeds?

Can I record video into iMovie from one source, while using another source for audio? I'd like to use my Canon ZR80 as a video source, but it has no audio input jack, so I have to use a lav or some other mic for audio.

Can I record video into iMovie from one source, while using another source for audio?
Are you trying to input the audio and video simultaneously or is the audio something you can do as an overlay? If the latter, then you can use the mic input or import previously recorded audio files from the "media" menu after you finish the video capture.

Playing audio and video files in JSF (.wav,.mp3)

Hi,
I would like to know how to play audio and video files such as .wav,.mp3 in jsf .
could any one please post the code for playing the wav files.
Thanks,
Ram

There is no JSF component to do this, so you would have to write your own custom component to render an <object ...> element.
Or, you can use <f:verbatim> wrapped around an html <object ...> element.
