I am seeing the same issue here....

I have made a case in the fora about this: https://tvheadend.org/boards/5/topics/24416

My setup is currently a test setup to see how it works. So this is how I am getting my signal

From Tvheadend server to my own Tvheadend server running Ubuntu 16.10 with version HTS Tvheadend 4.1-2405~geb495a0~xenial running

When I test with my rasp pi3 directly from my source it´s running smoothly.

What do there??

Hi,

I have a similar problem with my X86_64 TvH server. I see that the CC errors with IPTV inputs (multicast) increases over time. I don't know why, but it appears in all muxes (=streams). I check all network streams with a TS-Analyzer and I can't see any error (except puntuals time to time).

It's possible that TvH has troubles with the IPTV input? Can I increase the reading buffers?

I suggest to add a counter for CC errors based on time, like: TOTAL-CC-errors, CC-errors-last-60sec.
Perhaps this helps to fine-tune the server.

Could you try to increase IPTV_BUF_SIZE in src/input/mpegts/iptv/iptv_private.h ? Try value 3000*188 .

Hi Frank,

In the source code: http://github.com/tvheadend/tvheadend/blob/master/src/input/mpegts/iptv/iptv_private.h#L28

I'll do some checks. However, I suggest to move this define value to a configurable variable.

Jaroslav, please, can you add the option to reset "all" CC errors counters in the UI? This will simplifies a lot the testing.

I also have this issue since 4.1-2405~geb495a0~xenial from ppa
Not seen previously even when test recording 8HD simultaneously.
Fails with only single tuner in use.
Pixelation dropouts vary from ~10 seconds to worst case every second or two.

I have been getting the same over the past couple of years. Whatever I try, I have been unable to get it down to zero. This is on two different networks, both IPTV. I am quite certain it isn't anything in my own network, as I've tried every single combination known to man before eventually giving up. :-)

Tried to change the buffer value, but that doesn't seem to do much. The problems always seem to be in the video stream.

Example for the highest bandwidth stream I can test with (which happens to be a HEVC stream, but this happens to all my channels, also SD ones);

2017-01-12 13:50:01.919 TS: channelname: HEVC #4011 Continuity counter error (total 1)

2017-01-12 13:56:09.922 TS: *channelname*: HEVC

.. And this increases steadily over time.
