TVHeadend Server recording issue in CoreElec and LibreElec "Matrix", but work fine in "Leia"

Marco Rob

I’m going crazy for problems recording an Italian IPTV stream (RAI1).

With all the other channels I have no problems, with this one after a while I get these error messages in the console:

2022-02-02 12: 06: 09.754 TS: IPTV1 / iptvitaplus.m3u - Rai 1 / Service01: H264

# 256 Continuity counter error (total 1) 2022-02-02 12: 06: 09.754 TS: IPTV1 / iptvitaplus.m3u - Rai 1 / Service01: AAC

# 257 Continuity counter error (total 1)

The thing are repeated randomly, then the stream reconnects and the recording continues but then it is unusable, because it tries to hang up the stream and this creates a problem in the saved file.
Latest version of TVHeadend Server downloaded from repo for Matrix 19.4 RC2.
I am doing the same recording on CoreElec and LibreElec V9.x (Leia, Kodi V18.x) with the same settings and I have absolutely no problem, hours of recording on that channel without a single abnormal message.
To do a test I tried also to install TVHeadend Server on Ubuntu and in that the channel is perfectly recorded without ever problems.
Perhaps this IPTV sends out a particular stream that is misinterpreted in the version of TVHeadend for CoreElec/LibreElec "Matrix" (Kodi 19.x)... possible kernel issue?
Since Leia and Matrix use two different versions of FFmpeg (V4.x and V5.x) in those distributions, I also tried to replace it by downgrading it but the problem remains.
The mux: pipe:///storage/.kodi/addons/tools.ffmpeg-tools/bin/ffmpeg -loglevel fatal -hide_banner -re -i "https://mediapolis.rai.it/relinker/relinkerServlet.htm?cont=2606803" -c copy -f mpegts -flags +global_header pipe:1
Tested in two different tvbox: Tictid TX6 and X96Max Plus 2T (both sm1_s905x3_4g_1gbit.dtb).

It would be useful if any of you who use Matrix on a tvbox did the same check with this mux, thanks!

I'm trying now with the TVH 4.2.8 version, same problem, it's just something in the Matrix that gives the problem.
