2、ffmpeg轉碼

ffmpeg.exe -rtsp_transport tcp -buffer_size 4096000 -i "rtsp://admin:123456@192.168.1.2:554/Streaming/Channels/201" -vcodec copy -acodec copy -f flv rtmp://192.168.1.100:1935/myapp/0003

3、使用flv.js插入時，結果報錯：Unsupported codec in video frame: 2

意思是不輸出音訊（專案中用的攝像頭沒有音訊，所以此處用 -an，不輸出音訊）

ffmpeg.exe -rtsp_transport tcp -buffer_size 4096000 -i "rtsp://admin:123456@192.168.1.2:554/Streaming/Channels/201" -vcodec copy -an -f flv rtmp://192.168.1.100:1935/myapp/0003
