Hi,
I'm building a small Video-Chat-App and playing around with publishing video and audio.
Everything is fine on Desktop, but if i port the code to mobile I'm facing a kind of permformance issue.
So I build a small app just using Camera, Video and NetConnection/NetStream for testing.
If I attach the Camera to Video and switching between different resolutions (320x240, 480x360, 640x480 at 30fps, camquality at 75) the video is running smoothly.
But the framerate drops when I start publishing via NetStream, depending on the selected Camera-resolution.
Render mode is set to "direct", but I also tested the others without any good results. Building is done with AIR 3.5, tested on iPad2 with iOS 6.2.1 and Samsung S3 with Android 4.1.2
Using 320x240 is fine on both devices. but at 480x360 framerate on iPad 2 drops to 15fps, S3 still has 28fps. On 640x480 iPad drops to 10fps, S3 at 14fps.
Does anyone facing the same problems or has a tweak/solution or is this just depoending on the hardware/cpu because publishing via NetStream is eating a lot?
Any ideas, hints or informations are much appreciated.
Kind regards
Benny
