IPTV Channel Switching Time & Caching

Added by nanns ssj4 almost 7 years ago

Hi,

I am currently using IPTV in tvheadend 4.2.5. We have observed that channel switching time on playing a channel for the first time is about 3-4s. Once the channel is played then subsequent switching to the same channel will take about 2s. I think some kind of caching enables tvheadend to perform fast channel switching. Is there a way to control cache expiry such that it never expires ? Or is there an option which can enable periodic cache refreshes so that channel switching is always fast ?

Hey,

I have The same problem. I See When i‘m Using a Constant Running stream from a xtream of flussonic Panel i have No Delay (0,1 sec). If i use a transcoded or untranscoded stream from tvheadend i have always 2sec switching times.

Are you both make difference between live and on-demand streaming
p.s.
on-demand streaming on flussonic take 4-6+ seconds to switch channels
p.p.s
live streaming on flussonic is 10 seconds back in time

hey,

i want switching times under 0,5sec. so i import the channels from the first tvheadend (with tv card) in xtream or flussonic. The second tvheadend machine get the stream from xtream or flussonic and play it on client... in this setup i have very fast switching times.... but i dont want to use xtream or flussonic because its not free.

so is there a possibility that i can do it without these panels?

when i run the channels from first tvh in vlc and get the same channel with the second tvheadend the switching times always at 2. that flussonic have 10 seconds back in time is not important

Under 0.5sec only on multicast.

Hi

I am talking about IPTV over multicast. Initial switching time is about 3 seconds. Once the channel is played then subsequent switching to the channel takes about 1 - 1.5 seconds. So is there a caching mechanism in tvheadend ? After some time this cache seems to expire and channel again takes time initially.

Thank you
