通过 RTMP 进行视频流传输

Question

我需要将 RTSP 实时监控 URL rtsp://mylocation.4545 转换为 RTMP URL rtmp://127.0.0.1:1935/live/livestream1 我在 centos 中通过 ffmpeg 使用以下命令

 ffmpeg -i "rtsp://127.0.0.1.4545/live" -f flv -r 25 -s 640x480 -an "rtmp://127.0.0.1:1935/live/livestream1"

但是当我尝试这个时我收到了以下错误..

 [h264 @ 0x24de1e0]number of reference frames exceeds max (probably corrupt input), discarding one
