Hi!

After update
multimedia/mpv to version 0.40.0.1 with binary package I have a problem. Many times it freeze the laptop and help just power off.
I didn't change anything and in mpv.conf I have just:
Code: 
# Dont allow windows to be larger than the screen
autofit-larger=50%x50%
# Hardware decoding
hwdec=auto
# normal top-level option
fullscreen=no
Thank you.

hi mate

try these options

Code: 
vo=gpu
hwdec=vaapi

i have these packages installed on my dell xps 15 2019
which has an nvidia gpu and intel as well

Code: 
libva-intel-driver-2.4.1_3     VAAPI legacy driver for Intel GMA 4500 (Gen4) to UHD 630 (Gen9.5)
libva-2.22.0                   VAAPI wrapper and dummy driver
gstreamer1-vaapi-1.24.8        GStreamer hardware video decoding via VA-API plug-in

do you have ffmpeg installed and this package

Code: 
openh264-2.3.0,2               Cisco implementation of H.264 codec

im on freebsd 14.2 p2 quarterly branch

this is my mpv version

pkg info mpv
mpv-0.39.0_1,1

it is possible for badly encoded videos to cause mpv to crash the system
 
I will try. I have amd gpu and I am on latest branch.
And I have Openbox but many years as I am rusing MPV I didn't have problems.
I have installed openh264-2.3.0,2.
Thank you very much.

Mpv is based on the MPlayer and mplayer2 projects which it greatly improves.
It supports a wide variety of video file formats, audio and video codecs, and
subtitle types. Special input URL types are available to read input from
a variety of sources other than disk files. Depending on platform, a variety of
different video and audio output methods are supported.
 
FWIW... to check vaapi set up...

First identify your CPU architecture. Find your cpu name and look it up on intel.com

for example
$ cpuid | grep -i brand
Extended brand string: "Intel(R) Core(TM) i5 CPU M 560 @ 2.67GHz"

Chip support page is here
www.intel.com

Intel® Core™ Processors, FPGAs, GPUs, Networking, Software

Browse Intel product information for Intel® Core™ processors, Intel® Xeon® processors, Intel® Arc™ graphics and more.
www.intel.com www.intel.com
- from that page note Code Name 'Products formerly Arrandale', this is the architecture name.

Look up the architecture name here

List of Intel CPU microarchitectures - Wikipedia

en.wikipedia.org en.wikipedia.org

Find your codename in the list and check whether it was released before or after Broadwell. In this example Arrandale was released in 2010, before Broadwell which was released in 2014. Then choose which intel driver package to install as below.

$ pkg ins libva-intel-driver # for pre-broadwell cpus OR
$ pkg ins intel-media-driver # for broadwell and later cpus

Finally install libva tools
$ pkg ins libva-utils

Now run vainfo and check output looks reasonable. On my core i3-560m I get

$ vainfo
Trying display: wayland
Trying display: x11
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/local/lib/dri/iHD_drv_video.so
libva info: va_openDriver() returns -1
libva info: Trying to open /usr/local/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_1_22
/usr/local/lib/dri/hybrid_drv_video.so init failed
Not using hybrid_drv_video.so
libva info: va_openDriver() returns 0
vainfo: VA-API version: 1.22 (libva 2.22.0)
vainfo: Driver version: Intel i965 driver for Intel(R) Ironlake Mobile - 2.4.1
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Main : VAEntrypointVLD
VAProfileH264ConstrainedBaseline: VAEntrypointVLD
VAProfileH264Main : VAEntrypointVLD
VAProfileH264High : VAEntrypointVLD
VAProfileNone : VAEntrypointVideoProc

I'm not sure of the significance of the hybrid driver init failing is. But we get some valid VA entrypoints.

After doing this...

1. mpv with hwdec=vaapi works with hardware video decoding

2. in firefox, go to about:support and search for HARDWARE_VIDEO_DECODING
- if it shows 'available' as per my screenshot below, you get hardware video decode in firefox, eg for yt videos.
- you don't need to change any about:config settings (AFAIK!)
- you DO need to restart FF after installing the intel driver

So you now have hardware accelerated video decoding operational in both mpv and the firefox video player :)

And what is in case of AMD cpu and gpu?
And my settings
Code: 
autofit-larger=50%x50%
# Hardware decoding
vo=gpu
hwdec=vaapi
# normal top-level option
fullscreen=no

works but before update of mpv to version 0.40.0.1 I didn't have on my laptop T495 no settings and for my use everything worked.
 
I did change now hwdec from vaapi to vdpau and it works. I have just "problem" as I have before with messgae related to sound:
"Audio device underrun detected".
