I've been looking at opensource tools, but turns out my roommate has an old version of flash. All the webcam tuts I've seen don't work in this, i'm wondering if webcam controls even exist in as2 and if someone could possibly provide a simple explanation on how to make them work?
I have wowza media server running on my host and I want to be able to broadcast my webcam on a website using it.

Full disclosure: I'm a pretty junior developer and new to asking questions. I also don't know that much about video streaming as a concept so if the answer is right in front of my face I probably just glazed right over it.
That being said, I am trying to do something that seems like it should be pretty simple but can't seem to figure it out. I'm trying to get a H.264 live stream video off of a Raspberry Pi and view it in my app. I've found a number of things about encoding videos but couldn't seem to get anything to work.
Anything anyone has to offer would be a large help, even if it is just a direction to look in because I'm pulling my hair out trying to figure this one out.
You'll first need to install some platform on your Raspberry Pi that can serve data to a client. You can look into web server platforms like Apache. Once installed, you can verify this is working by hitting the IP address of the Raspberry Pi from any browser: e.g. 192.168.1.67:80
Then you need to make sure the video is available through the file system on your Raspberry Pi. Searching something like "Adding files to Apache" might help.
You can test that the file is available by hitting the IP address of your Raspberry Pi from any browser: e.g.
192.168.1.67:80/path/to/video.mp4
This means that the video file is available and can be downloaded, but won't be streamed by default. Then you can look into some JavaScript framework that can help you with the streaming portion.
Apple has super famous HLS protocol for streaming videos. You would need to first encode video input coming from camera, then pass it to your server who's basically doing all the "behind the scene" work and provides you with *.m3u8 URL. I've implemented this pattern with Wowza Streaming Engine. You can use it or similar tools.
On the flip side, if you're inclined towards having more simple and straight forward solution; more like a CDN approach, then you may follow #Bret's answer.
I'm working with opencv to read the frames from a RTSP streaming link via VideoCapture function. It worked well for a specific RTSP camera. But the thing is, I have tried to connect different RTSP cameras in the same network but for my surprise, it wouldnt work.
Any thoughts of what could cause this problem? I need to be able to get the stream of any rtsp url with the same openCV code for my purpose.
The camera that worked is a generic chinese one and it also worked with the big buck bunny comic provided by rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov. The second camera that I tried and got no outputs is an AirCam Dome from Ubiquiti wich has 4 rtsp links. I tried every resolution.
Check if you have 'opencv_ffmpeg341.dll' or something like this in your running folder.
If you are using Windows system, put the dll in x64 or x86 folder.
I was wondering if it would be possible to capture the live video from my integrated webcam using Labview 2011(National Instruments). All I need to do for now is put the camera in the front panel. This is not a USB Webcam. It is a chicony USB 2.0 Camera(does not show up as usb on my pc). Can anyone help me?
LV2012? Is this beta?
The best way to do this is using IMAQdx drivers+Vision Developement module. AFter installing IMAQdx, USB cams usually already show up in Measurement and Automation Explorer and you can try out Snap/Grab... (Tip: Do install whatever driver is included with the hardware/on a cd.)
Then, in LV, just drop the "IMAQ Acquisition Express" vi into your block diagram and you'll be guided through a very quick and easy setup.
I'm not much into Express vis, but that one is good.
If you don't have Vision Dev Module, look into ADVision (http://vi-lib.com/). It does the same thing, just with OpenCV, but I don't think that every driver is supported.
Also, remember only USB cameras that have DirectShow filter are supported by the Vision Acquisition Software, which has the IMAQdx that Birgit P. mentioned.
for usb2 you need imaqdx toolkit in vision acquisition part
also check NIMax after installation to see if labview could find your camera or not
labview could find and support all useb2 camera if you instal camera diver correctly
I'm trying to save time on a project I'm beginning that will record audio from the connected audio input devices on a Windows XP or Windows 7 PC. In the past I have used the DSPACK components for Delphi 6 Pro to do video capture on a Windows PC, but I am wondering if it is the best solution for doing a project that only needs to record audio, not video. Is DSPACK still the way to go or is their a faster/easier solution to recording audio via Direct3D from the PC's connected audio input devices? Sample rate conversion and other similar features in a suggested solution would be desirable too. Links to tutorials, etc. are also appreciated.
If you are familiar with DSPack and using DirectShow filters then it is a good choice for the job. DSP-Worx have an audio filter (DCDSPFilter) that provides a range of effects and they also have DirectShow Interface (LameDShowIntf) to the Lame encoder.
You may also want to consider using GMFBridge to reduce latencies to a minimum.

I think you can find this components real usefull for your work...
I'm writing LabVIEW software that grabs images from an IMAQ compatible GigE camera.
The problem: This is a collaborative project, so I only have intermittent access to the actual camera.I'd like to be able to keep developing this software even when the camera isn't present.
Is there a simple/fast way to create a virtual or dummy IMAQ camera in software? Ideally I'd like the dummy camera grab frames from an AVI or a stack of JPEG's. Something like this must exist, I just can't find it on Google.
I'm looking for something that won't take very long (e.g.< 2 hours effort) and that is abstracted away through the standard LabVIEW IMAQ interface, so that my software won't know or care whether its dealing with a dummy camera or an actual camera.
You can try this method using LabVIEW classes:
Hardware Emulation Using LabVIEW Classes
If you have the IMAQdx driver, you might consider just buying a cheap USB webcam for $10.
Use the IMAQdx driver (assuming you have it), and then insert the Vision Acquisition Express VI, and you can choose AVIs or even pics as a source.
Something like this: GigESim is a camera emulation software. Unfortunately it is proprietary and too expensive (>$500) for my own needs, but perhaps others will find this link useful.
Anyone know of a viable Open Source alternative?
There's an IP Camera emulator project that emulates IP camera with python. I haven't used it myself so i don't know if it can be used by IMAQ.
Let us know if it's good for you.
I know this question is really old, but hopefully this answer helps someone out.
IMAQdx also works with Windows DirectShow devices. While normally these are actual physical capture devices (think USB Webcams), there is no necessity that they have to be.
There are a few different pre-made options available on the web. I found using Open Broadcaster Studio and this Virtual Cam plugin to be easy enough. Basically:
Download and install both.
Load your media sources in the sources list.
Enable the VirtualCam stream (Tools > VirtualCam). Press Start.
