What will be the resolution for no audio in RTMP output due to not having extradata in the copyts mode i.e stream copy?

/opt/ripcode/bin/ffmpeg -copyts -i /root/ModernFamilyVMGCapture.ts -async 0 -vsync 0 -f flv -mpegts_pmt_start_pid 480 -map 0:2,0:0 -vcodec copy -b:v 544000 -muxdelay 0 -map 0:0 -codec:a:0 copy -flags +global_header -metadata:s:a:0 language=fra -b:a:0 128000 -bsf:a aac_adtstoasc rtmp://
