Some HEVC does not have hardware decoding.
Posted: 06 Nov 2022 13:52
My laptop has a core i3 1115g4 processor with integrated intel graphics and installed ubuntu 22.04.1 with ubuntu-restricted-extras and vlc player version 3.0.16 installed.
In general, hardware acceleration in the vlc player works fine in almost all hevc and h264 videos, the gpu is involved during playback and therefore the CPU is not heavily loaded, but still, sometimes there are such videos (hevc) in which hardware acceleration does not work.
1. I have enabled hardware acceleration in vlc player using vaapi. Settings--InputCodecs--HW accelerated decoding = VAAPI.
2. Ubuntu has free and non-free codec packages by default, the first ones were installed by default, and I replaced them with non-free, because only the non-free package has the VC1 codec.
3. I also checked for codecs.

Description: VAAPI driver for the Intel GEN8+ Graphics family
The VA-API (Video Acceleration API) enables hardware accelerated video
decode/encode at various entry-points (VLD, IDCT, Motion Compensation
etc.) for the prevailing coding standards today (MPEG-2, MPEG-4
ASP/H.263, MPEG-4 AVC/H.264, and VC-1/WMV3). It provides an interface
to fully expose the video decode capabilities in today's GPUs.
.
This package contains the video decode and encode driver backend for the
Intel HD Graphics of the Intel Core processor family. The supported platforms
include:
* Broadwell
* Skylake
* Broxton
* Apollo Lake
* Kaby Lake
* Coffee Lake
* Whiskey Lake
* Cannon Lake
* Ice Lake
