Jittering movements on some H.265 streams on DVB-T2

Yes. Unfortunately I’m trying to fix another playback issue first as that will likely impact this file as well.

OK Sam, in 4.9.113-20 the problem still persist. Will let you know next update, looking forward even for epg fix in kodi 18.7.
Thx

I would recommend checking this upstream with Kodi.

I will check this.

The first post in the 4.9 thread is updated with buster repository

[TESTING] Linux 4.9 kernel and improved video stack for Vero 4K / 4K +

Summary Since we launched the Vero 4K in February 2017, we’ve been shipping Linux 3.14 to support this hardware. In 2018, we modernised the media stack by backporting Linux 4.9 drivers to this 3.14 kernel, which enabled us to support a wider variety of DVB tuners. Linux 3.14 has been end of life for some time. As part of our commitment to long term support, we’d like to move to a more modern kernel and take advantage of a number of upstream improvements from the system-on-chip (SoC) vendor. …

hey @Bary I´ve tested with buster and latest 4.9 kernel and problem still persists. Now i think problem is not just in player but in tvheadend and signal strength. Reason for signal strength is cause of jittering is sometimes visible and sometimes is picture fine during same day. So maybe it is signal strength dependent.
