How to merge audio video file in mac system using action script? - macos

I am creating a screen recording application using action script. I am able to record the screen and audio files separately but the issue i am facing is that i am not able to merge these audio and video files in Mac.
For windows version i have used the ffmpeg and it is working fine But for Mac system it is not working. Do you guys have any other suggestions or any way to run the ffmpeg from the action script directly for Mac ?

Capture and Record Desktop Screen with/as Webcam Video

Webcam lets others view either still pictures or motion video of a user or other object in front of it. I want to configure Webcam in a way that it start capturing desktop screen instead of what is in front of it.
I want to manipulate desktop screen captured through Webcam using FFMPEG library. Such as:
ffmpeg -f dshow -i video="Integrated Webcam" -f mp4 cam_stream.mp4
I want to use this same application to capture my Desktop Screen that will be possible just in that case when Webcam will be able to capture my Desktop Screen instead. So above command will start recording what Webcam will be capturing that I want it to capture my desktop screen.
Note: I know other ways to capture, record or stream desktop screen but I want to achieve it through Webcam.
What I tried so far: I tried some Fake/Virtual Webcam software (manycam, sparkocam etc.) but I don't think they fulfil what I exactly want.
P.S. I posted the same question in another community but didn't get any response.
Please guide me if there is any way to achieve this? Thanks
Solution to this problem would be to capture desktop directly by using ffmpeg.
Follow the link Capture Desktop using ffmpeg
Ive been searching all day for a similar thing.
Ive found this: https://streamshark.io/blog/using-obs-as-a-virtual-webcam-on-windows-and-macos/ With this software you can create a virtual cam that can utilize a portion of your screen as a fake webcam output.
Exactly what I need and what I think the OP is talking about.
So for future ref, bumped.
(Why do I need this for instance?: I dont have a smartphone, but a virtualbox android. I want to install the windows desktop app versions of certain apps. For which I need to "hold the phone (virtualbox) in front of a computer screen (main os)"...
On this forum see this post on capturing the desktop:
Capture Windows screen with ffmpeg
If I understand well, you also want to add views from your webcam. The above mentioned link on capturing the desktop shows how to use dshow. So the desktop and the webcam are both input streams for your output mp4.
I suggest to add your webcam as input:
-f dshow
-i <webcam>
Next, e.g. use the overlay filter to put both the desktop and the webcam on one view.

Firefox OS Simulator media storage

I'm testing the Firefox Simulator recently, and I noticed that for the add-on simulator the Gallery reads the pictures from /pictures on my pc, and Video reads the videos from /videos as well.
Later I ran the simulator on my mac, it can get music from /itunes, pictures from /users/username/pictures but I don't know where to put the video files for the simulator to read. I have tried the fake-sdcard folder and /users/username/movies, they both didn't work.
Thank you.
you can put .mp4 or .3gp videos in any point of the fake-sd folder
this should work

Microsoft Player Framework not playing local files

I am developing a windows 8 app in winjs and one of its features is to be able to play local video files. So far I am using:
Windows.System.Launcher.launchFileAsync
Which works fine but obviously suspends the app and opens the video with their default video program. I would rather keep the user in the app so I tried to implement it using the Microsoft Player Framework(http://playerframework.codeplex.com/). I know the framework is referenced correctly etc because it can play video files both in the 'app data' directory and online.
However when I try to play files within a folder that the user has picked (with the folder picker) or the videos library that the app has declared access to, the video fails to play. The app can however change the name, create new files in the directory and delete files so I struggle to see a permissions problem.
To get the path of the file I am using getFileAsync( and using the path property and simply using that to set the src property of the MediaPlayer control.
Do any windows 8 app gurus have any suggestions as to why it is not working?
Thanks in advance
p.s. let me know if any further info is required

capture video from screen for stream

i am looking for differnt solutions to capture video stream from monitor screen and send it to vidoestreaming server to broadcast in web. it must occuring in "live".
i'd not like to use external services like "procaster" for broad.
OS: Windows.
it will be great to know the ideas and expirience people have to accomplish that.
Thanks all.
Recently, I build a GoLang project called ScreenStreamer, is a tool to stream current active window or full screen (Linux's or Windows's) to other device, like phone or another PC, as MJPEG over http or FLV over rtmp, it's very realtime (delay < 100ms). It works on Windows and Linux.
After building it, you can run it as:
# enter the project root directory
cd ./src/ScreenStreamer
# run it
./mjpeg or .\mjpeg.exe
# use a web browser or other video player, open http://host:port/mjpeg
./rtmp or .\rtmp.exe
# use a video player, open rtmp://host:port/live/screen
Screenshot:
Windows SDK includes Push Source Filters Sample, which in turn contains CPushSourceDesktop filter/class.
CPushSourceDesktop: Copy of current desktop image (GDI only)
It captures desktop image and pushes it into DirectShow pipeline. From there on you can process it using video compression codec and stream it to remote location. A decent screen image compression codec is included with Windows Media subsystem, network streaming will have to be a custom or third party component. Alternatively, it is possible to make the capture class a virtual camera and have Windows Media Encoder broadcast it (or, it already has a simila feature built in).
Alternatively, you can check VNC (or one of the clones) source code and see how it hooks windows and captures image updates, then compresses them and makes it available for remote applications.
Note that you will have to specifically capture non-GDI images (such as coming from video/gaming applications, which use hardware acceleration and non-RGB surffaces).

WP7 emulator won't play mp4

I was wondering if the format is really supported. I am developing a simple WP7 application which contains a MediaElement such as the one shown bellow:
For the sake of testing, I subscribed for the MediaFailed event and it fires always.
If I try to open the file in the browser, it opens successfully. If I put the same MediaElement in a regular SL application - it runs. If I give some .wmv file to the MediaElement in the WP7 app - it runs. (http://files.ch9.ms/ch9/5baa/ea2aeba2-9dcc-4565-942a-9e6101655baa/DevKid_ch9.wmv).
Got any ideas?
One thing to watch is that video won't play if you're connected using USB to the Zune software.
I just tried your video using this IronRuby script - it plays fine.
For more help, you can check out the Channel9 application on codeplex - that works well.
Windows Phone 7 supports the MP4 container, but only supports a certain set of codecs. I believe this list is a pretty accurate list of what's supported.
It seems that you can't play mp4 files when Zune is running. However, you can still debug your application by connecting to your phone using WPConnect.exe which by default is installed to C:\Program Files\Microsoft SDKs\Windows Phone\v7.0\Tools\WPConnect. You'll need to close Zune before running WPConnect, but after you have run it, you should be able to F5 in Visual Studio and the the debugger running your code on the phone.
One other thing to keep in mind is that Windows Phone 7 requires the file (or URL) extension to match with the codec, so for mp4 files you need to have file name ending with .mp4, otherwise it won't play.
