This is GStreamer module that packetize 188 bytes TS packets into one UDP packet. I wrote it because I need raw UDP stream from gstreamer, but without packetizer each TS packet sent in UDP packet independently, but this makes highly packetized stream, where some packets may be dropped due rate-limit or shaper. So some solution for decreasing packetisation is needed.
The standard IPTV-UDP packet contains 7 MPEG-TS packets, and I can't find any plugin that do the trick. The similar plug-in is rtpmp2tpayload, but it adds RTP header to the stream, and some IPTV Set-Top-Boxes can't play this stream.
gst-launch -v -e --gst-debug=*:2,udptspayload:3 alsasrc device="plughw:0,0" slave-method=0 ! queue leaky=1 ! \
audiorate ! aacplus ! \
queue ! flutsmux name=muuxer ! udptspayload packets=6 ! \
queue ! udpsink host=220.127.116.11 port=1234 ttl-mc=16 auto-multicast=true
You can adjust how much packets to collect befor give then to the next module. Just add "packets=[number]
Maybe the same task can be done with "queue2" plugin magic, but I can't successfuly do the trick with it.
