Android Camera Streaming

[m_g_]

My app is based on the Camera Streaming sample code. I am seeing low frame rates while streaming (my test device is  4.4). Before streaming the preview looks like it's full frame rate (> 24fps). Once i start the capture it drops to 3-4 fps for the preview and the stream to Wowza. I have disabled all effects in the pipeline. The CPU shows 36% idle. Any thoughts?

Hi,

Can you provide us more details on your test device. You are using Android OS 4.4? Also once the application starts capturing and streaming simultaneously directly to Wowza, there is a negligible drop in framerate, but not to 3-4 fps. Can you test the internet connectivity speed when the test device and Wowza are connected on the same network. We have tested on Android tablets and donot see the performance drop.

Thanks,

I am using a Samsung S3 that's been reset to factory settings. My Wowza server is on my local Wifi network and the Wowza GoCoder downloaded from the Play store streams at 30fps at a higher bandwidth from the same device.

Hi,

We confirm that performance\fps differ from device to device in capturing scenario. Our assumption is that SW codec in used instead of HW by some reason. Our tests show that this is device problem, not INDE or CameraCapturing in particular. Most of devices give normal FPS, but there are several exceptions.

Thanks,
