UDP multicast ? any tutorial available?

Hi guys

Ok so far i have done some searching in the forum and i could not find any specific information about support for UDP multicast on tvheadend.

Lets make things clear, aldo HTSP is working great atm, i have several problems.

1- audio delay out of sync due to TCP, the OS must buffer the lost segments for every client. This is bad, particularly in the case of live events;

2- IP multicast, i need it in our working environment testing office we have around 70 devices on a gigabit network, when over 40 devices connected streaming on the network our network bandwidth starts getting slow..

3- I want to reduce my LAN bandwidth by using IP multicast + UDP because there are no

4- Also IP multicast does not work with TCP protocol..

Any information available about modifying the tvheadend source to enable multicast and UDP ?

I have the same problem. I want to multicast Tvheadend output to UDP. There is a old fork where a user has enabled UDP: https://github.com/zakalibit/tvheadend/tree/master-multicast

Somting as:

ffmpeg -re -i http://localhost:9981/play/stream/channel/1231231321231 -vcodec copy -acodec copy -f mpegts udp://239.0.0.1:1234

ffmpeg can be replaced with avconv in some distros

Can be used also with rtp(s)://224.0.1.2:1234
