Sending video and audio using RTP

Hi All,
I'm searching for a java networking guru that can might help.
My mission is to create a video/audio streaming server. I can't use JMF because it cannot create two processors at the same time, which means that I can't have two threads in the JVM send different media files.
I have tried to use this example :
http://www.csee.umbc.edu/~pmundur/courses/CMSC691C/lab5-kurose-ross.html
The thing is that I don't understand how to add audio capability to this example. How can I synch the audio/video using java code in RTP ?
Does anyone have a simple example of how to send audio/video over RTP without JMF ? I don't care what format it should be.
Thanks for any help,
Tom.

Can we capture the video and audio using cam and microphone in Edge Animate?

Hi Everyone,
I got a new requirement from the client to create a HTML5 based functionality through which one can capture the video and audio using his web-cam/camcorder and microphone. I have researched on internet and found that there is api available (not reliable) http://www.html5rocks.com/en/tutorials/getusermedia/intro/ . I am not a coder by profession and use Edge animate to create HTML 5 based animations and stuff like that. Another problem which i have found that the api only works well with Chrome and Opera and not with Mozilla, IE..
Can anybody help me out in this, please...
Thanks & Warm Regards

Hi, Vikas-
After a brief bit of research, you're definitely hitting upon the limitation of the browsers. Not all of the browsers have implemented this part of the HTML5 standard, so you're going to either have to use Flash or be limited to these specific browsers.
Thanks,

How to send video and audio (videoconference) using JMF without using RTP

Hi everyone,
I am creating an application using JMF, a videoconference, but I would like to transmit the packets by myself without using RTP. I would have a socket (or virtual Serial Port -- > Bluetooth) and I would send the info that way. Is it possible??
Thanks in advance!!
Cheers

Yeah, you'd need to implement something like this for that.

Flex, Record video and audio using web camera to computer temp, then upload

Hello all,
I'm not sure if this is 100% possible and have been looking around for some time now for an answer but couldn't find one so have come here.
Basically I want to create a flex application that sits in a web browser, that allows people to connect using a webcam and microphone, then record a short video that gets held temporarily on the computer until they finish and then it uploads the whole video to a server.
I am able to achieve this by using a media server and streaming the video directly from the user to the server but this hinders the quality of the videos. On poor Internet connections the quality is rubbish.
Is it at all possible to save video files to a computers temp memory and then upload them ?
This would mean I can record the videos at a nice high quality and not have to worry about the Internet connection tampering with the quality.
Many Thanks in advance !

Thanks for the reply. I knew it was not possible to write to the C drive or the users computer at all.
But i really wanted to know if it was possible to write to a dataArray or byteArray within flex?
I should of mentioned this sorry.

How to combine rtp data containing video and audio?

Hi
I have a problem. I was examining with AVTransmit3.java and AVReceive3.java. I found that AVTransmit3 sending video and audio with different ports. It's okey as it is done as JMStudio. but my question is how can I receive this packets as raw bytes and combines them into one media file to play at a time in a player. May be very fundamental question but tough for me as i m novis as jmf programmer.

Look in the JMF Guide regarding multiplexors and demultiplexors. It give the whole breakdown of how this works (and I think examples).

After years of owning all things Mac, I am finally trying to use iChat, and can't get it to work. I see my buddy, but all I can do is send a message--the video and audio chat icons are gray, as is inviting to a video chat under Buddies.

After years of owning all things Mac, I am finally trying to use iChat, and can't get it to work. I am using gmail, and I see my buddy (no camera icon next to her name), but all I can do is send a message--the video and audio chat icons are gray, as is inviting to a video chat under Buddies. My buddy has the same problem as I. We are able to do video chat through gmail, but I had hoped to use iChat. I am using OS 10.6.8, iChat v. 5.0.3. What am I missing?

HI,
iChat will Video chat to another iChat in a Jabber Buddy List (Google run a Jabber server for GoogleTalk)
However it will not Video to the Web Page login to iGoogle or the Web Mail Page login. (where people can Google Chat as it were in a Web Browser).
Nor does it video to the Google Talk Stand alone app for PCs or any other Jabber apps on any platform.
iChat uses a connection Process called SIP (Session Initiation Protocol) which is also used by other VoIP devices.
Jabber/XMPP invited the Jingle Protocol for Jabber Applications.
Google have included this in their Standalone app and the Plug-in for Web Browsers on both PCs and Mac (you can get this as a Standalone Plug-in or as part of Chrome)
More on this here This article has been changed several time in the recent months. It now claims a greater involvement by Google in writing the Jingle Library (Although now Google's version does not work with the others)
This tends to mean that using the web Login to Google to Chat also cannot video chat to other Jabber apps that are using Jingle.
If your Buddy is using iChat then check the Video Menu has two items to Enable Camera/Video chat and Microphone/Audio chats are ticked.
In the View Menu the Show Status Items should be ticked (Selecting them toggles the tick and the function On or Off)
It could be Internet speed but at this stage I would doubt this at this stage.

Hello All...
Back after a brief absence, things look a little bit different.
I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.
Thanks!

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

With newer MacBook Air, sending both video and audio to an LG TV works fine, but I want to send the audio to a sound bar attached to the TV. Any way to do this?

I am trying to get audio to play through the soundbar attached to the TV for great sound. Works fine with Apple TV, but on the MacBook Air, system preferences will only find the TV speakers. If I change the settings on the TV to external speakers (the soundbar), then I get no sound at all. The HDMI connection does what it is supposed to do, providing video and audio, but the audio can only go to the TV. I don't know if you can go backward and send only video through HDMI and then connect to the soundbar through the mini jack ports on the computer and the soundbar. Any solutions will be appreciated.

its important to do this in the correct order so the camera will be senced by the Mac and to prevent the Firewire connection from electrical damage:
power down your Mac
connect firewire from camera to Mac
power on camera and insert tape in camera and play back
power up Mac
start QuickTime
File > Preferences > record tab
video source - select the camera you have
sound source - select the camera you have
quality - select device native
the video should show in the QuicTime window
a green line below video will show presence of sound-it will play through the speakers if they are selected in system prefernces
rewind tape and playback
click on red button to start recording

How can you use one NetStream to publish video and audio from another NetStream in AS3?

Let's say one of your client programs in AS3 is able to receive live video and audio from a NetStream and play it on the screen. How could you make it also take that video/audio stream that it's receiving, copy it over into another NetStream, and publish it elsewhere? I need to know how to do with this regardless of whether RTMP, RTMFP, or some mixture is involved. The reason why the stream needs to be relayed this way is a real long story, but it's necessary in this particular case. Thanks!

RTMP is TCP, which has higher overhead and latency because it guarantees packets are delivered (handshaking, causing latency and overhead). It also doesn't allow you to share connections directly between clients forcing the server to do all the work.
RTMFP uses UDP, which is a choice protocol for streaming video because it's the opposite. It's lossy which decreases latency and overhead from no retransmissions and most importantly (in some applications) allows you to connect directly from one Flash Player to another Flash Player (p2p) so the server overhead is dramatically reduced. The server is only required to negotiate the initial connection and then it's up to the clients to continue to facilitate that.
How you code your one to many or many to many relationship broadcast network will be based entirely on which of those you choose.
URLStream is very common to use in p2p. Here's an older Adobe article on p2p and an alternate quick old video tutorial (FP10) as a quick simple example of p2p over RTMFP you can view the source of.

1)access the router web ui
2)go to the Mac Address Clone subtab , enable it and click "Clone" . Save the settings
3)do a power cycle
4)check whether the router gets an internet ip add now ..

Can I use iMovie to edit and enhance both video and audio of my homemade DVDs?

I have a lot of homemade DVDs converted from old VHS tapes. The video and audio quality need to be edited/enhanced. Can I use my iMovie 11 for this task? If not what are my options? Thanks.

Hi
There are several layers to this Q
• VHS-tapes has a low quiality as is
• converted to sort of .mpe2 to a DVD to be played on standard DVD-player - Quality is futher lost
• converting it back to DV or AIC - and more quality is lost
• edit it in iMovie'08 to 11 - even more quality is lost due to that when going from Event's to Project's - every second line building up the picture is discarded (as non of them - iM'08 to 11 - works woith interlaced SD-video
So if quality is of any interest - I would - and are doing
• Converting from VHS-tapes
- via a CANOPUS ADVC-300 - to digital
- in via FireWire to
- to iMovie HD6 or FinalCut (any version) - asa they all keep 100% of the interlaced SD-quality
- edit and put out on miniDV tape (still 100% preserved) or to a DVD made in iDVD with all that keep as high quality possibly. (No Video-DVD can keep 100% quality - it's due to standard and amount of compressing)
If Quality is of no importance - then
• DVDs needs to be converted to DV or AIC and this is no free standard on any Mac - You need a converting program as
- MPEG StreamClip (free on internet) + BUT it needs the .mpeg2 Component from Apple to work ($20)
- Roxio Toast™ - can also be used to back engineer - BUT this cost's much more - still to me all extras was more than worth it
- Analog way - DVD-player - A/D-box - import via FireWire

I am trying to use the auto audio-sync feature. When I select the video and audio clip to be synced FCPX says its syncing them and then once finished (at 100%) no compound clip is created and the video and audio file do not sync. Any help is appreciated.

Hi
In iMovie'11 (version 9.0.x)
on top menu row - Apple/iMovie/File/Edit/Cut (Can vary dep. on language - in Swedish Apple/iMovie/Arkiv/Redigera/Klipp . . . )
down Cut menu - Slow playback/Raspid Playback/Re-play in Slow Motion and onvards
Here one can select the Pre-Set speeds
Are you familiar with getting 'inspector' to run?
No - but I guess that Double Click on clip/sequense or ctrl-Click on it might open it.

Video and audio out of synch on burned DVD. DVD project appears to be fine. I'm using 1X speed to burn disc. Project info indicates plenty of space. What should I do?

Video and audio are out of synch on some chapters of a burned double layer DVD. The iDVD (7.1.2) project seems to be fine. I'm burning the DVD using a 1X speed. What else can I do to solve this problem. Based on the project information, I have plenty of space relative to the DVD capacity.

Follow this workflow to help assure the best qualty video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
