Question

Is this possible? Someone tried to do on-line recording of audio and video(of the screen) with ffmpeg? I read everything google can find about ffmpeg in the net. The variant of recording I deed load CPU to 100%, but it still can't convert frames with appr. speed relevant to how fast frames are recording, audio go good, but video lost frames..

Answer 1

This pretty much depends on the codec used, the frame size/complexity and obviously the capabilities of the computer doing the compression. You can try a low complexity codec like MJPEG, which might improve your experience.

Answer 2

Recording audio/video of the screen is possible with ffmpeg. People do this for the purposes of screen casting. Performance of this depends on the hardware in use, the codecs used and various other factors.
