我将尝试在 lubuntu 20.04 中使用mpv_thumbnail_script 我对这个脚本的配置
cat .config/mpv/lua-settings/mpv_thumbnail_script.conf
#Für Vorschaubildchein in mpv
cache_directory=/home/alex/mpv/my_mpv_thumbnails
autogenerate=yes
prefer_mpv=yes
mpv_no_sub=yes
disable_keybinds=yes
thumbnail_width=200
thumbnail_height=200
thumbnail_network=no
thumbnail_count=150
min_delta=5
max_delta=90
我的 mpv 配置
cat .config/mpv/config
#hwdec=vdpau
#vo=vdpau
fullscreen
sub-scale=1
osc=no
但是当我启动 mpv 时缩略图是黑色的。
从终端开始
mpv jd2/downloads/Aang\ \&\ Tenzin\ -\ Clip_\ Avatar\ The\ Legend\ of\ Korra/Aang\ \&\ Tenzin\ -\ Clip_\ Avatar\ The\ Legend\ of\ Korra\ \(360p\).mp4

我不确定是我犯了错误，还是脚本本身有问题。
注意：我不会写脚本。我发现了这个这个问题并点击答案中的链接，但我不知道该做什么。
答案1
我可以通过改变来解决这个问题
.config/mpv/lua-settings/mpv_thumbnail_script.conf
部分
prefer_mpv=yes
到
prefer_mpv=no
即使在 PATH 中找到 ffmpeg，也使用 mpv 生成缩略图 ffmpeg 比 mpv 稍快，但不支持 MKV 中有序的 >章节，这可能会破坏生成的缩略图。您已收到警告。默认为是（不使用 ffmpeg）prefer_mpv=[yes/no]
使用 ffmpeg 制作缩略图，可以工作。
