what's new /mpv/?
dav1d
my cpu's too old to handle it
How do I into 4k on my t420 (i5-2520M)? MPV stutters but I can play the same file fine in VLC.
whats your config?
default

test what works best for your hardware and OS
didn't help
What OS are you running?
loonix
what did you try? what is your config now?
we aint doing the work for you
gpu-context=x11
gpu-api=opengl
hwdec=vaapi-copy
Its not like there is much I can change
Are you on wayland? Can you get a hardware decoder running and confirm it's running by checking the stats (it should tell you what hwdec is running in the video line)?
KDE so x11
Looks like my HD3000 doesn't support 4k for some reason it wasn't throwing up those errors until I restarted
[ffmpeg/video] h264: Hardware does not support image size 3840x2160 (constraints: width 0-2048 height 0-2048).
[ffmpeg/video] h264: Failed setup for format vaapi_vld: hwaccel initialisation returned error. still these videos play in vlc without dropping frames
here is a different video thats not 4k
Using hardware decoding (vaapi-copy).
AO: [pulse] 48000Hz stereo 2ch float
VO: [gpu] 1280x720 nv12
fucked up code tags im not going to fix it
try gpu-context=x11probe and hwdec=vaapi and see what the log says
[vo/vdpau] VDPAU is most likely emulated via VA-API.
[vo/vdpau] This is inefficient. Use --vo=gpu instead.

vo=gpu
[vo/gpu] Failed initializing any suitable GPU context!
Error opening/initializing the selected video_out (--vo) device.
Video: no video
are you using a downloaded 4k video? how do you know vlc is playing it with hwdec?
or you may need to update your drivers/use the right driver
vlc is probably using software I don't care what it uses just as long as it works
You get that on a config that only has vo=gpu? Do you have proper drivers for video?
that was with
gpu-context=x11probe
gpu-api=opengl
hwdec=vaapi-copy
vo=gpu
using just vo=gpu gets video but it still drops frames
Remove the gpu-context line for now. You can try gpu-api=vulkan if your build supports it; it may give you better performance. You need drivers for vulkan too. Also use hwdec=vaapi, using copy might bring you bad results.
are you streaming or did you dl a file?
download
I didn't realize the hd3000 supported vulkan ill try it
it helped I still don't think its perfect but its serviceable right now I still get this error
[ffmpeg/video] h264: Hardware does not support image size 3840x2160 (constraints: width 0-2048 height 0-2048) but its not dropping tons of frames
Try using bicubic_fast
