• sdp : Add an option for sending RTCP packets to the source of the last packets

  13 août 2013, par Martin Storsjö

  sdp : Add an option for sending RTCP packets to the source of the last packets
  An SDP description normally only contains the target IP address
  
  and port for the packets. This means that we don’t really have
  
  any clue where to send the RTCP RR packets - previously they’re
  
  sent to the destination IP written in the SDP (at the same port),
  
  which rarely is the actual peer. And if the source for the packets
  
  is on a different port than the destination, it’s never correct.
  With a new option, we can choose to send the packets to the
  
  address that the latest packet on each socket arrived from.
  
  — -
  
  Some may even argue that this should be the default - perhaps,
  
  but I’d rather keep it optional at first. Additionally, I’m not
  
  sure if sending RTCP RR directly back to the source is
  
  desireable for e.g. multicast.

• Stream mp4 file to multicast using ffmpeg ?

  17 décembre 2018, par Stuart

  I have a mp4 video with no sound that I want to stream to a multicast address on a loop, I can connect to the stream group to play but it’s just empty when I play in VLC but the timer in VLC changes as if something is playing.

  ffmpeg -re -stream_loop -1 -i testvideo.mp4 -s 640x480 -vcodec copy -f mpegts udp://238.100.100.1:1234

  I’ve also noticed that the size doesn’t seem to work either ?

  Any help would be great. Thanks

• Get rtsp udp streaming with ffmpeg utility failed

  16 février 2021, par Lidor Abo

  Hey there,
I have a problem with get streaming from wowza stream engine as described below :
I try to get streaming in private network from wowza stream engine in UDP with ffmpeg as following :
ffmpeg -loglevel debug -rtsp_transport udp -i "rtsp ://192.168.8.117:1935/live/ecad838c-b431-4c8b-b2e8-d43f78a8d2f2.stream" -acodec copy -vcodec copy test.mp4
and i get the following error :
rtsp ://192.168.8.117:1935/live/ecad838c-b431-4c8b-b2e8-d43f78a8d2f2.stream : Connection timed out
Few remarks about that :

  


  

  1. When i try to get streaming using public ip with ffmpeg utility i success in UDP and TCP

  


  2. I success to get streaming with private IP with TCP connection through ffmpeg utility as following :
ffmpeg -loglevel debug -rtsp_transport tcp -i "rtsp ://192.168.8.117:1935/live/ecad838c-b431-4c8b-b2e8-d43f78a8d2f2.stream" -acodec copy -vcodec copy test.mp4

  


  3. I open 1935 UDP and TCP ports in security group of wowza stream engine for machines that will need to get streaming from wowza stream engine. Also, i opened UDP in 6970-9999 range for any ip address.

  


  4. I added relevant IP address in Whitelist property in Server.xml conf in wowza stream engine.

  


  5. I using vpn service (perimeter) to access the machine that from it i get streaming from wowza streaming engine.

  


  6. iptables in machine that i try to get stream allow any rule and not enabled any firewall.
Note : i adding link to zip file with logs and config files because is not me your upload limitations :
