Hi,
I have been trying to record screen with audio using ffmpeg but I do not

Hello,
I want to dynamically (per frame) zoom out/scale down a video below 100% size.

Hi everyone,
I am implementing a SIP user agent (softphone) in C++ where the media
encoding and decoding is handled by ffmpeg. I basically have one PCMU
encoder and one PCMU decoder. Taken separately they both works fine.
To cope with NAT traversal issues, I need to do Symmetric RTP
