RE: Screenshare in AIR
Thank you, Hector!!
This helped greatly, and I got the AIR app working just as expected. This is awesome! Now, I'm just working on getting the AIR app and the ffmpeg files all put inside an installer (.exe and .dmg). Didn't think this would end so easily.
The only downside is that I wont be able to get this working on mobile since the NativeProcess isn't supported.
Any ideas on how such a feat can be accomplished through an Android/iOS AIR app?
Thank you again!
- David

Subject: Re: Screenshare in AIR
With ffmpeg there are tons of ways of doing something and parameters to
set... so I'll just give one sample commandline, then you can investigate a
bit further googling around or you can always try to ask and if we can
reply we'll do so:
-f gdigrab -framerate 30 -i desktop -vcodec libx264 -vb 500000 -g 60
-vprofile baseline -level 3.1 -pix_fmt yuv420p -acodec none -f flv rtmp://
127.0.0.1:1935/live/screenshare
-f gdigrab: tells ffmpeg to use a built-in device it has that captures
Windows windows through GDI. There are more capturers that use other
methods like DirectShow.
-framerate 30: the framerate at which the window content is captured.
-i desktop: tells the device to capture the desktop, you can also use
title="window name" to capture a particular window, you can also capture a
particular area, make it output the video in a smaller size (if you are
seeing the remote window in a small area why send the original image), etc.
-vcodec libx264 -vb 500000 -g 60 -vprofile baseline -level 3.1 -pix_fmt
yuv420p -acodec none: tells ffmpeg to stream using h264 in a format Flash
understands: -vb 300000 is the bitrate (300kb/s in this case, you could use
variable bitrate with different conditions), -g 60 is the keyframe
interval, -acodec none tells the stream has no audio, gdigrab doesn't
capture the audio anyway.
-f flv rtmp://127.0.0.1:1935/live/screenshare: tells to stream the video in
Flash video format, to a RTMP server (some local Red5 installation).

Thank you, John.
It looks very interesting. I'll check this out as another option of doing this app.
Thanks again!

Yes, more or less like you say. FFMPEG is a library on mobile, already in ObjectiveC on iOS, and I think it's written in C for Android and the NDK has to be used, you can still use it from Java, but it makes things a bit harder, I guess there are already some easy-to-go libraries out there for it.
You'd have to design and write AS code that communicates with native code (Objective C or Java) that you have to write as well, and that native code would then use the native ffmpeg library, you can check the documentation for making your own ANEs here:

RE: Screenshare in AIR
Posted by David Frank <Da...@on24.com>.
Hi Hector,
Yes, that is what I was wondering myself. But, from my Googling of this info, it looks like I have to write the ANE in C or Java. So, does this mean I have to write a Java/ObjectiveC class that invokes ffmpeg? Or is there a simpler way?
Thank you again for helping me out.

For mobile you'd need an ANE, as ffmpeg is used as a library in that case.

Re: Screenshare in AIR
Posted by Héctor A <ne...@gmail.com>.
For mobile you'd need an ANE, as ffmpeg is used as a library in that case.

RE: Screenshare in AIR
Posted by David Frank <Da...@on24.com>.
Hi Fabrice,
Actually, it was a lot simpler. I simply moved the ffmpeg installation folder under a folder called extlib of my project's src, and referenced it relatively in my code (that is, instead of C:/ffmpeg/bin/ffmpeg.exe or whatever, I used extlib/ffmpeg/bin/ffmpeg.exe). On exporting the application in FlashBuilder, the ffmpeg got included in the application's installer. Piece of cake!
Thank you,
David

Hi there,
You can juste compile as executable and create an installer with some other tools if you want to include some libraries. Really easy to do.
Hope that helps.
