Load Certificate File: How to import a DTLS certificate and private key from a file?

[winlinvip]

To import a DTLS certificate and private key from a file, you should first generate an SSL certificate and private key file or obtain them from a Certificate Authority (CA) service.

openssl genrsa -out dtls.key 2048
openssl req -new -x509 -key dtls.key -out dtls.crt -days 3650 \
    -subj "/C=CA/ST=Toronto/L=Toronto/O=Me/OU=Me/CN=ffmpeg.org"

Then use -cert_file and -key_file to load it:

~/git/ffmpeg-webrtc/ffmpeg -re -f lavfi -i testsrc=size=1280x720 -f lavfi -i sine=frequency=440 -pix_fmt yuv420p \
    -vcodec libx264 -profile:v baseline -r 25 -g 50 -acodec libopus -ar 48000 -ac 2 \
    -f whip -cert_file dtls.crt -key_file dtls.key \
    "http://localhost:1985/rtc/v1/whip/?app=live&stream=livestream"

It works.
