我有一个rtp流，服务器正在2个单独的端口上接收音频和视频，视频在VP8中，音频在Opus中。
我的最终目标是将RTP流转换为RTMP，再将其转换为Youtube Live，但是Youtube Live仅支持H264 https://developers.google.com/youtube/v3/live/guides/ingestion-protocol-comparison，因此首先，我希望将我的RTP流转换为H264。
我已经运行了以下命令
ffmpeg -analyzeduration 300M -probesize 300M -protocol_whitelist file,udp,rtp -i test.sdp -c:v libx264 -pix_fmt yuv420p -r 25 -c:a aac -f flv youtube_rtmp_url
我的sdp文件
v=0
o=- 0 0 IN IP4 127.0.0.1
s=RTP Video
c=IN IP4 127.0.0.1
t=0 0
a=tool:libavformat 55.2.100
m=audio 50000 RTP/AVP 111
a=rtpmap:111 OPUS/48000
m=video 50002 RTP/AVP 100
a=rtpmap:100 VP8/90000
a=fmtp:100 packetization-mode=1
其中50000和50002是用于接收rtp视频和音频的端口。
