Totem 在全新安装的 19.04 中播放 H.264 需要哪些编解码器？

  • 772

我全新安装了 Ubuntu 19.04，但无法在 Totem 中播放 MP4 视频。按照安装必要解码器的建议未成功。我必须安装哪些编解码器才能播放此视频文件，它使用 H.264（High Profile）视频编解码器和 MPEG-4 AAC 音频编解码器？

在安装过程中，我选中了安装第三方图形软件和其他媒体格式的复选框：

我启用了 main、universe、restricted 和 multiverse 存储库。

我已经安装了多个 gstreamer 包和编解码器：

我安装了 Totem，带有默认的包和插件：

tom@desktop:~$ apt list --installed | grep totem
gir1.2-totem-1.0/disco,now 3.32.0-1ubuntu1 amd64 [installed,automatic]
gir1.2-totemplparser-1.0/disco,now 3.26.3-1ubuntu1 amd64 [installed,automatic]

totem-plugins/disco,now 3.32.0-1ubuntu1 amd64 [installed,automatic]
totem/disco,now 3.32.0-1ubuntu1 amd64 [installed,automatic]

我没有安装ubuntu-restricted-extras，因为我不想要额外的包（Microsoft 字体等），但我手动安装了libavcodec-extra libavcodec-extra58其中包含的 AV 编解码器（ ）：

tom@desktop:~$ apt-cache depends ubuntu-restricted-extras
ubuntu-restricted-extras
  Depends: ubuntu-restricted-addons
  Recommends: libavcodec-extra
    libavcodec-extra58
  Recommends: ttf-mscorefonts-installer
  Recommends: unrar

我注意到我可以通过将视频文件从 Nautilus 拖到空的 Firefox 或 Chromium 选项卡中来播放视频文件，但 Totem 不会播放它。

当我单击“在 Ubuntu 软件中查找”按钮时，Ubuntu 软件显示消息“无法找到请求的软件”（最后一点可能是一个错误，但我不介意，我只需要知道要手动安装哪些软件包） . 请问有什么建议吗？如何在全新的 19.04 安装时在 Totem 中播放此文件？

编辑：在进一步故障排除后，我发现 Totem 将播放相同的文件，如果它们是 MKV 容器格式而不是 MP4。我使用youtube-dl（最新版本，不是来自 repos）下载 BBC iPlayer 视频。我可以设置--merge-output-format mkv选项并播放下载的文件。如果没有该选项，它会输出到我无法播放的 MP4。这是一个不错的解决方法，但我很想知道究竟是什么干扰了 MP4 播放并解决了这个问题。

如果您在 iPlayer 服务的区域并希望进行测试，我使用了这个短短的三分钟视频https://www.bbc.co.uk/iplayer/episode/p07hlmxr/the-news-explained-a-tale-of-two-tankers，它下载文件The_News_Explained_A_Tale_of_Two_Tankers.fstream-uk-iptv_streaming_concrete_combined_hd_mf_limelight_uk_dash_https-video=5070000.mp4，The_News_Explained_A_Tale_of_Two_Tankers.fstream-uk-iptv_streaming_concrete_combined_hd_mf_limelight_uk_dash_https-audio_eng_1=128000.m4a然后将它们合并到 MP4 或 MKV 中。

    gstreamer1.0-vaapi请先做一个模拟有问题。apt --dry-run purge gstreamer1.0-vaapi因为依赖。

  2. 我最近遇到了类似的问题，安装gstreamer1.0-libav修复了它。

  3. 使用 totem 3.34.1 会弹出一个对话框，在 Ubuntu 软件中搜索 GStreamer 多媒体编解码器。

    从类别安装GStreamer plugins from the "bad" set版本后，totem 可以播放 avi。1.16.2-2.1ubuntu1Add-ons → Codecs

    GStreamer Bad Plug-ins 是一组与其他插件相比无法达到标准的插件。它们可能接近于良好的质量，但它们缺少一些东西——无论是良好的代码审查、一些文档、一组测试、一个真正的实时维护者，还是一些实际的广泛使用。
