在 Ubuntu Gnome 17.04 中使用 ffmpegthumbnailer 时没有 mp3 缩略图(专辑封面)

在 Ubuntu Gnome 17.04 中使用 ffmpegthumbnailer 时没有 mp3 缩略图(专辑封面)

我使用 Nemo 作为默认文件浏览器,并且我想使用ffmpeg缩略图工具生成缩略图。所以我安装了ffmpeg缩略图工具并编辑了totem.缩略图文件/usr/share/thumbnailers并添加

TryExec=/usr/bin/ffmpegthumbnailer Exec=/usr/bin/ffmpegthumbnailer -s %s -i %i -o %o -c png -f

所以我的系统使用ffmpegthumbnailer而不是totem-video-thumbnailer 但每次我这样做时,nemo(和nautilus)都会停止生成如图所示的mp3缩略图(2) 如下。我想使用,ffmpegthumbnailer因为您可以让视频具有电影条覆盖(2)并且由于totem-video-thumbnailer某些视频文件缩略图上有紫色(1)。

1使用 totem-video-thumbnailer 处理 Mp3 和视频文件

2使用 ffmpegthumbnailer 处理 Mp3 和视频文件

因此,当我使用下面的原始 totem.thumbnailer 行时,我得到了图片1
我的原始 totem.thumbnailer 文件包含 totem-video-thumbnailer 行:

当我使用这个(带有 ffmpegthumbnailer 行的 totem.thumbnailer)时:

我得到了图片2

mp3 标签不是问题,因为正如你在图片中看到的那样1我得到了带有 的艺术封面totem-video-thumbnailer。我认为这是 ffmpegthumbnailer 中的一个错误。

我总是删除~/.cache/thumbnails。我使用的是 Ubuntu Gnome 17.04,nautilus 也出现了同样的问题,只是缺少视频叠加(nautilus 默认会添加视频叠加)。我能做些什么来解决这个问题,或者做些什么让我可以使用带有电影条叠加的 nemo,并且缩略图上没有颜色?

答案1

我通过将两个文件放入来解决问题/usr/share/thumbnailers

  • 首先,我totem.thumbnailer用这个替换:

     [Thumbnailer Entry]
     TryExec=/usr/bin/totem-video-thumbnailer
     Exec=/usr/bin/totem-video-thumbnailer -s %s %u %o
     MimeType=audio/x-pn-realaudio;audio/3gpp;audio/3gpp2;audio/aac;audio/ac3;audio/AMR;audio/AMR-WB;audio/basic;audio/dv;audio/eac3;audio/flac;audio/m4a;audio/midi;audio/mp1;audio/mp2;audio/mp3;audio/mp4;audio/mpeg;audio/mpg;audio/ogg;audio/opus;audio/prs.sid;audio/scpls;audio/vnd.rn-realaudio;audio/wav;audio/webm;audio/x-aac;audio/x-aiff;audio/x-ape;audio/x-flac;audio/x-gsm;audio/x-it;audio/x-m4a;audio/x-matroska;audio/x-mod;audio/x-mp1;audio/x-mp2;audio/x-mp3;audio/x-mpg;audio/x-mpeg;audio/x-ms-asf;audio/x-ms-asx;audio/x-ms-wax;audio/x-ms-wma;audio/x-musepack;audio/x-pn-aiff;audio/x-pn-au;audio/x-pn-wav;audio/x-pn-windows-acm;audio/x-realaudio;audio/x-real-audio;audio/x-s3m;audio/x-sbc;audio/x-shorten;audio/x-speex;audio/x-stm;audio/x-tta;audio/x-wav;audio/x-wavpack;audio/x-vorbis;audio/x-vorbis+ogg;audio/x-xm;application/x-flac;
    

(我删除了除audio/...MimeType 之外的所有内容)

  • 其次,我ffmpeg.thumbnailer用这个创建了:

     [Thumbnailer Entry]
     TryExec=ffmpegthumbnailer
     Exec=ffmpegthumbnailer -i %i -o %o -s %s -f
     MimeType=video/jpeg;video/mp4;video/mpeg;video/quicktime;video/x-ms-asf;video/x-ms-wm;video/x-ms-wmv;video/x-ms-asx;video/x-ms-wmx;video/x-ms-wvx;video/x-msvideo;video/x-flv;video/x-matroska;application/mxf;video/3gp;video/3gpp;video/dv;video/divx;video/fli;video/flv;video/mp2t;video/mp4v-es;video/msvideo;video/ogg;video/vivo;video/vnd.divx;video/vnd.mpegurl;video/vnd.rn-realvideo;video/vnd.vivo;video/webm;video/x-anim;video/x-avi;video/x-flc;video/x-fli;video/x-flic;video/x-m4v;video/x-mpeg;video/x-mpeg2;video/x-nsv;video/x-ogm+ogg;video/x-theora+ogg
    

(我从 MimeType 中删除了除视频/... 之外的所有内容)

我现在可以看到 mp3 和视频文件的缩略图。这在 Nautilus 上对我来说是可行的,但我想在 Nemo 上也应该可以。
