Ffmpeg Raspberry Pi如何将RTSP流h265转换为h264

我正在尝试将H265 rtsp流转换为H264

ffmpeg -rtsp_transport tcp -i 'rtsp://admin:admin123@192.168.1.42:554/stream2' -f lavfi -i aevalsrc=0 -vcodec copy -acodec aac -map 0:0 -map 1:0 -c:v libx264 -pix_fmt yuv420p -shortest -strict experimental -f flv rtmp://localhost:1935/live/stream

当我使用这个命令时，它给出了这个错误

[tcp @ 0x23f13b0] Connection to tcp://localhost:1935 failed: Connection refused
[rtmp @ 0x23f1270] Cannot open connection tcp://localhost:1935
rtmp://localhost:1935/live/stream: Connection refused

如果FFmpeg应充当服务器，则必须添加参数

-listen 1

ffmpeg -i 'rtsp://admin:admin123@192.168.1.42:554/stream2' {...} -f flv -listen 1 rtmp://localhost:1935/live/stream
