<p>Distributions usually split libraries in several packages. The main package
contains the files necessary to run programs using the library. The
development package contains the files necessary to build programs using the
library. Sometimes, docs and/or data are in a separate package too.
</p>
<p>To build FFmpeg, you need to install the development package. It is usually
called ‘<tt>libfoo-dev</tt>’ or ‘<tt>libfoo-devel</tt>’. You can remove it after the
build is finished, but be sure to keep the main package.

<p>For multithreaded MPEG* encoding, the encoded slices must be independent,
otherwise thread n would practically have to wait for n-1 to finish, so it’s
quite logical that there is a small reduction of quality. This is not a bug.

<p>Both Xvid and DivX (version 4+) are implementations of the ISO MPEG-4
standard (note that there are many other coding formats that use this
same standard). Thus, use ’-c:v mpeg4’ to encode in these formats. The
default fourcc stored in an MPEG-4-coded file will be ’FMP4’. If you want
a different fourcc, use the ’-vtag’ option. E.g., ’-vtag xvid’ will
force the fourcc ’xvid’ to be stored as the video fourcc rather than the

material, and try ’-top 0/1’ if the result looks really messed-up.

<h3class="subsection"><ahref="faq.html#toc-Concatenating-using-the-concat-demuxer">3.14.2 Concatenating using the concat <em>demuxer</em></a></h3>
<p>FFmpeg has a <ahref="http://www.ffmpeg.org/ffmpeg-formats.html#concat"><code>concat</code></a> demuxer which you can use when you want to avoid a re-encode and
your format doesn’t support file level concatenation.

<p>FFmpeg has a <ahref="http://ffmpeg.org/ffmpeg-protocols.html#concat"><code>concat</code></a> protocol designed specifically for that, with examples in the
documentation.
</p>
<p>A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow to concatenate
video by merely concatenating the files containing them.

<h2class="section"><ahref="faq.html#toc-Why-does-FFmpeg-not-see-the-subtitles-in-my-VOB-file_003f">3.17 Why does FFmpeg not see the subtitles in my VOB file?</a></h2>
<p>VOB and a few other formats do not have a global header that describes
everything present in the file. Instead, applications are supposed to scan
the file to see what it contains. Since VOB files are frequently large, only
the beginning is scanned. If the subtitles happen only later in the file,
they will not be initally detected.
</p>
<p>Some applications, including the <code>ffmpeg</code> command-line tool, can only
work with streams that were detected during the initial scan; streams that
are detected later are ignored.
</p>
<p>The size of the initial scan is controlled by two options: <code>probesize</code>
(default ~5Mo) and <code>analyzeduration</code> (default 5,000,000 µs = 5s). For
the subtitle stream to be detected, both values must be large enough.
<h2class="section"><ahref="faq.html#toc-Why-was-the-ffmpeg-_002dsameq-option-removed_003f-What-to-use-instead_003f">3.18 Why was the <code>ffmpeg</code>‘<samp>-sameq</samp>’ option removed? What to use instead?</a></h2>
<p>The ‘<samp>-sameq</samp>’ option meant "same quantizer", and made sense only in a
very limited set of cases. Unfortunately, a lot of people mistook it for
"same quality" and used it in places where it did not make sense: it had
roughly the expected visible effect, but achieved it in a very inefficient
way.
</p>
<p>Each encoder has its own set of options to set the quality-vs-size balance,
use the options for the encoder you are using to set the quality level to a
point acceptable for your tastes. The most common options to do that are
‘<samp>-qscale</samp>’ and ‘<samp>-qmax</samp>’, but you should peruse the documentation

<p>FFmpeg builds static libraries by default. In static libraries, dependencies
are not handled. That has two consequences. First, you must specify the
libraries in dependency order: <code>-lavdevice</code> must come before
<code>-lavformat</code>, <code>-lavutil</code> must come after everything else, etc.
Second, external libraries that are used in FFmpeg have to be specified too.
</p>
<p>An easy way to get the full list of required libraries in dependency order
is to use <code>pkg-config</code>.
