If you want the H.264 encoder, then

The package that fixed it for me on 16.04 is the gstreamer plugins bad.
I got a message about Python-3.5 minimal wanting to install some MPEG-4 AAC plugin, which did not do anything. To fix:
In a terminal type:

<pre><code>sudo apt-get install gstreamer1.0-plugins-bad
</code></pre>

If you still can't get it to work somehow, you can try VLC as a workaround, installable by:

<pre><code>sudo apt-get install vlc
</code></pre>

I did not unclick the restricted software, that may work but may disable other codecs.
By the way, movie player or Video is the Totem video player.

blocks|key|2876339|text|我认为这是gstreamer坏包的一部分。如果你在软件中心搜索这个，它应该会出现。它可能是，您必须激活多体存储库(启动软件和源，并勾选适当的方框)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2876340|安装软件包后，Movie应该能够播放该文件。|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|E|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|F|8|@]|9|@]|A|$]]]|D|$]]

I think this is part of the package gstreamer-plugins-bad. If you search for this in Software Center it should show up. It might be that you have to activate the multiverse repository (start Software &amp; Sources and tick the appropriate box for this).

After you have installed the package, Movie Player should be able to play the file.

<h1>The audio-only gstreamer bug can easily be resolved</h1>
Hearing only audio on H.264 playback with an otherwise black video screen was reported as <code>gstreamer1.0</code> <a href="https://bugs.launchpad.net/ubuntu/+source/gstreamer1.0/+bug/1562875" rel="nofollow noreferrer">bug #1562875</a>.
Luckily, this bug can easily be resolved by issuing the following command once:
<pre><code>$ rm -R ~/.cache/gstreamer-1.0
</code></pre>
This will take effect after restarting the application.

blocks|key|268315|text|我在播放视频时也遇到了同样的问题。视频播放器想要下载mpeg+-4acc解码器和h.264解码器，但由于法律原因(-if+I正确地理解了在pc试图下载上述程序后在窗口中写入的内容)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|268316|在我打开软件并更新->+Ubuntu软件->之后，受版权或法律问题(multiverse)限制的软件"unclick“都重新开始工作。(我的意思是说，在这次操作之后，pc下载了他需要的东西，并开始工作了)。|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|E|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|F|8|@]|9|@]|A|$]]]|D|$]]

I had the same problem with playing videos. Video player wanted to download mpeg - 4 acc decoder and h.264 decoder, but this hadn`t happened due to legal reasons (-if I understand correctly what was written in the window what appears after pc was trying to download mentioned programs).

After I unclicked Software &amp; updates -> Ubuntu software -> "unclick" Software restricted by copyright or legal issues (multiverse) all start working again. (I mean that after this operation pc downloads what he needed and that it started working).

Following this video (<a href="https://www.youtube.com/watch?v=Vk5viMViSXk" rel="nofollow noreferrer">https://www.youtube.com/watch?v=Vk5viMViSXk</a>) worked for me. Now, I am able to play and seek forward/backward h264 files created by my Chinese IP Camera.

To sum up:

<ul>
<li>Open VLC. </li>
<li>Go to: <code>Tools</code>/<code>Preferences</code>. Select <code>Show settings</code>: `All'</li>
<li>In <code>Input / Codecs</code> / <code>Demuxers</code>, select <code>Demux module</code> as <code>h264 video demuxer</code>. Save and restart VLC.</li>
</ul>

Now you should be able to play h264 file.
