I want to play MPEG-4 Part 2 multicast streaming on VLC, but can not.

MPEG-2 and H.264 multicast streaming was able to play.

How can I play it?

  • OS: Windows 8.1 Pro 64bit

  • VLC Version: 2.2.4

  • Command: vlc -I dummy -vvv udp://@{MulticastAddress}:{Port}

Logs:

  • what is your source encoder? & are you sure your multicast is working? – user3788685 Oct 20 '16 at 07:43
  • I just heard only with the "MPEG-4 stream", and got the captured packets. multicast is working. – nkmr Oct 20 '16 at 08:06
  • I dont understand 'I just heard only with the "MPEG-4 stream"' - I'll have a check on my decoders when I get into work as we use VLC & encode our own mcast services – user3788685 Oct 20 '16 at 08:10
  • You are right. I have just checked it again, encoder is Fujitsu IP-700II. – nkmr Oct 21 '16 at 01:12
  • I've just checked my encoder - its only encoding MPEG2. I need to have a look at another unit as I *think* I had an issue with MPEG4 and a CCTV network so I need to try and find some very old notes. There was all sorts of settings on the encoder I had to change to get it to play nice with our system – user3788685 Oct 21 '16 at 10:41
