How to show thumb for videos loaded by yt-dlp

[ahaoboy]

https://github.com/po5/thumbfast
https://github.com/marzzzello/mpv_thumbnail_script

I tried using the two libraries above, but neither seems to support

If it is a remote file stream or a webdav file, thumbfast works fine, but it cannot preview the video played by yt-dlp

./mpv.com 'https://www.youtube.com/watch?v=Ugb80d5lxEM'

[geextahslex]

I'm not sure what you mean by that. This is your youtube video mpv(38)+yt-dlp(nightly) and mpv_thumbnail_script

[ahaoboy]

mpv v0.38.0-611-g202ecc17 + yt-dlp(nightly) + mpv_thumbnail_script

The following error message is output

It also doesn't seem to work for some video formats.
The same mp4 file, but the former does not report an error and does not display a thumbnail

[geextahslex]

I have no idea, I just try to give some help
Are you loading the script the "normal" way, so on startup and in the default "scripts" folder? If you are using any other method, this makes scripts behave in a weird way.
I am also a bit confused about what "C:\msys64" is supposed to be. I don't have this folder on my system. My mpv_thumbs_cache is located at "C:\Users\Deep\AppData\Local\Temp\mpv_thumbs_cache" so your folder structure is completely different.
Are you on windows? ^^'

[ahaoboy]

I use the Windows11, C:\msys64\Temp is the system's temporary directory

I use portable_config to load scripts and only include this script

my yt-dlp.exe is in the same location where mpv.exe is

I use the Windows11, C:\msys64\Temp is the system's temporary directory

I don't know because I'm on Win 10, but here you can see that temp is also somewhere else on Win 11

[ahaoboy]

my yt-dlp.exe is in the same location where mpv.exe is

Finally found the reason, thank you very much, I used the configuration to specify the address of yt-dlp, but the thumbnail can only be displayed correctly when it is in the same folder as mpv.exe. This seems to be a problem with the processing of a path in the code.

script-opts=ytdl_hook-ytdl_path=portable_config/yt-dlp/yt-dlp

Awesome
