FFmpeg
We have tools whipinto and whepfrom for support rtp
<-> whip
/whep
convert
For Example:
ffmpeg -> whipinto -> live777 -> whepfrom -> ffplay
Video: VP8
Video Test Src
bash
# send RTP and Create SDP file
ffmpeg -re -f lavfi -i testsrc=size=640x480:rate=30 \
-vcodec libvpx -f rtp 'rtp://127.0.0.1:5002' -sdp_file input.sdp
For ffplay. You Need a sdp file
bash
ffplay -protocol_whitelist rtp,file,udp -i input.sdp
You can use whipinto
tools receiver RTP and convert to WebRTC
bash
# Use SDP file as input
whipinto -i input.sdp -w http://localhost:7777/whip/777
bash
whepfrom -o output.sdp -w http://localhost:7777/whep/777
For ffplay. You Need a sdp file
bash
ffplay -protocol_whitelist rtp,file,udp -i output.sdp
