Slow tuning channels Kodi 16

DVBLink Kodi PVR addon is discussed here

Slow tuning channels Kodi 16

Postby GuiltyNL » Thu May 05, 2016 10:01 am

I have:

1) Synology 411+ II
2) DVB Link Server 5.1.1
3) Octopus NET V2 Tuner
4) Kodi 16 on a Windows 7 machine with gigabit LAN connected

Everything seems to work well, but I want to troubleshoot slow channel tuning / channel change.

It takes about 6 to 10 seconds to tune a channel. Where do I need to look?

When I tune a channel I can see in the DVBLink Server Monitor that the tune start instantly and after a second or two I see the bitrate and the packets running. (no errors or discontinues).

After that it takes another 4 to 6 seconds before Kodi starts showing the stream.

I tested to play a recording in Kodi too. The recordings are stored on the NAS ofcourse and recordings starts in 1 second or so.

What to do?

Can you try to use the VLC for test?
- install and launch the VLC player and press the combination Ctrl+N
- in the "Please, enter a Network URL" enter:http://ip-of-your-server:8100/mobile/?command=get_playlist_m3u
- start to play channel /switch to another ... results?

FTA channels take about 5 seconds to show the first image and about another second to get the image moving.

Encrypted channels are about 1 second slower. So 6 seconds to show the first image and 7 to 8 seconds to get the image moving.

I also tried to tune directly a rtsp link via the tuner, but I can't get that to work.

OK, please, set log level to info, restart dvblink server, conduct the tests with the channels switching once more and attach zipped log files here .

As i see at the log files the channels switching in your case takes from 3-4 up to 5sec. So, if it takes longer, it may be the network issue, or maybe some firewall/antivirus software cause such behaviour.

These two lines:
Code: Select all
2016-May-06 13:37:46:   [I] CTSStreamWaiter::GetPidToCheck. PID to check 2301
2016-May-06 13:37:51:   [I] CTSStreamWaiter::ProcessStream. Found first not encrypted packet. Start streaming

say that it takes 5 seconds to decrypt stream. This is where your issue resides.

Re: Slow tuning channels Kodi 16

Postby GuiltyNL » Fri May 06, 2016 1:17 pm

No firewalls or antivirus installed. Not on my Synology and not on my HTPC.

But 5 seconds is still slow isn't it? In my Mediaportal / Anysee Tuner solution the channel change was 2 seconds, 3 seconds maximum.

The first three channels are FTA (3 or 4 seconds) the rest is encrypted. Can I state that my OctopusNet tuner needs 2 seconds to start decrypting?

And of course my Kodi also needs some time to start the stream after receiving it. So we have the initial tuning time like below + 1 or 2 seconds for Kodi for fire up the stream. Making it in total a second or 6 / 7 per channel change.

Which is a pretty frustrating matter for my wife and thus a show stopper to use this solution.

I summarized my log and it seems indeed like this:

say that it takes 5 seconds to decrypt stream. This is where your issue resides.


Agreed, so I can say that in the above case my OctopusNet V2 tuner is causing this delay, correct?

Yes. The command to start decrypting was sent to Octopus here:

Clear!

Is it possible to speed up the rest a bit with a second or so? I'm considering a new Synology NAS for example. Could a better processor speed up the first part?

And would it be faster in general to put DVBLink Server on a fast Windows server instead of on my NAS?

I have disabled PVR caching / buffering in Kodi and that saves me a second or two.

Now testing the tuningspeed directly on my Octopus tuner and will compare this with my kodi tuning speed. The difference between the two would be more or less the DVBLink server is my guess.

I've done three things at once now and channel switching is fast. But I need to figure out what the main cause is:

1) Moved my DVBLink TV Server from my Synology to the client PC where Kodi also runs on
2) Disabled Windows Defender
3) Disabled Firewall

To be continued :)

I would say the biggest culprit is the Synology. I have a Synology DS411J and used to run multiple services on it (SB, CP, NZB etc) and the CPU used to suffer as a result (like constantly maxxed out CPU etc). Have since moved all these services on to a Raspberry Pi2 and use the Synology just for storage.
