Hello,
I am using melted as a playout server with outputs: a decklink monitor card
and avformat udp ouput.
I do not have any problems when my input clips have only one audio channel,
but if they have more than one I only get the first audio channel in the
output.
Can anyone help me?
I provide *details below:*
melt -version
melt 6.3.0
*INPUT CLIP:* test_audio_3.mp4
*INPUT CLIP DETAILS:*
mlt@OVE-DAG:~/test_files$ cat test_audio_3_details.txt

</mlt>
As you can see: there are three audio tracks in the input clip.
*MELT COMMAND:*
melt eof=loop -profile atsc_1080i_50 test_audio_3.mp4 -consumer
avformat:udp://224.168.225.202:2002?pkt_size=1316\&reuse=1 real_time=1
terminate_on_pause=0 f=mpegts vcodec=mpeg2video vb=5M s=1280x720 acodec=mp2
ab=256k
This is the melt command I am using (the same in melted server) but in
udp://224.168.225.202:2002 multicast address I only get the first audio
track.
Any help would be really appreciated.
Regards,
David
