Optimization audio video

Post by staff@ergosoft.it » Wed Mar 22, 2017 7:22 pm

Hi,

I'm trying the components ... in a slow ADSL line (10 Mbs download and 1 Mbs upload) ...

some question:

1) what are the optimal settings ? i use the FFMPEG library
2) the sound is very poor ... if I try to increase the quality you only hear noises ...

I use it with server component...

thanks
Alessandro Romano

FFmpeg is used only for receiving video from IP cameras, it is not used for local (USB) web cameras and for sending and receiving video.

If you want to reduce bandwidth,
1) Assign RVCamSender.Encoding = rvetJPEGChange to send only changed video fragments. Probably, it may require to adjust properties to detect changed fragments better, you can test in Demos\SendAndReceive\SingleApp
2) Assign lower value of RVCamera.FramePerSec
3) Assign lower RVCamera.VideoResolution

There are some problems with sound playing on the receiver side, we are working on improving, I hope sound will be better in the next update.
