+<a name="fftools_rename"></a><h3>August 09 2011</h3>
+
+<p>
+For consistency with our new name we have renamed <b>ffplay</b> to
+<b>avplay</b>, <b>ffserver</b> to <b>avserver</b> and <b>ffprobe</b> to
+<b>avprobe</b>. Their behavior is the same, just the names were changed.
+</p>
+
+<p>
+With <b>ffmpeg</b> (the commandline tool) we decided to use this opportunity to
+fix some longstanding usability problems, which involves breaking
compatibility.
+Therefore we have added a new tool named <b>avconv</b> which is based on
+<b>ffmpeg</b>, but has a different (hopefully more powerful and easier to use)
+syntax for some options.
+<b>ffmpeg</b> will be kept in its current state for some time, so no scripts or
+frontends using it will break. However it will not be developed further.
+</p>
+
+<p>
+Differences between <b>avconv</b> and <b>ffmpeg</b> are:
+<ul>
+ <li>In <b>ffmpeg</b> some options (like <i>-newvideo/-newaudio/...</i>) are
+ irregular in the sense that they're specified <i>after</i> the output
+ filename instead of before, like all other options. In <b>avconv</b> this
+ irregularity is removed, all options apply to the next input or output
+ file.</li>
+ <li><i>-newvideo/-newaudio/-newsubtitle</i> options were removed. Not only
+ were they irregular and highly confusing, they were also redundant. In
+ <b>avconv</b> the <i>-map</i> option will create new streams in the output
+ file and map input streams to them. E.g. <i>avconv -i INPUT -map 0
+ OUTPUT</i> will create an output stream for each stream in the first input
+ file.</li>
+ <li>The <i>-map</i> option now has slightly different and more powerful
+ syntax:
+ <ul>
+ <li> Colons (':') are used to separate file index/stream type/stream
+ index instead of dots. Comma (',') is used to separate the sync stream
+ instead of colon.. This is done for consistency with other
options.</li>
+ <li> It's possible to specify stream type. E.g. <i>-map 0:a:2</i>
+ creates an output stream from the third input audio stream.</li>
+ <li> Omitting the stream index now maps all the streams of the given
+ type, not just the first. E.g. <i>-map 0:s</i> creates output streams
+ for all the subtitle streams in the first input file.</li>
+ <li> Since -map can now match multiple streams, negative mappings were
+ introduced. Negative mappings disable some streams from an already
+ defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
+ all the stream in the first input file, except for the second audio
+ stream'.</li>
+ </ul>
+ <li> <i>-vcodec/-acodec/-scodec</i> options are gone, replaced by <i>-c</i>
+ (or <i>-codec</i>), which allows to precisely specify target stream(s)
+ consistently with other options. E.g. <i>-c:v lib264</i> sets the codec
for all
+ video streams, <i>-c:a:0 libvorbis</i> sets the codec for the first audio
stream
+ and <c>-c copy</i> copies all the streams without reencoding.</li>
+ <li> It is now possible to precisely specify which stream should an
AVOption
+ apply to. E.g. <i>-b:v:0 2M</i> sets the bitrate for the first video
stream,
+ while <i>-b:a 128k</i> sets the bitrate for all audio streams. Note that
the
+ old <i>-ab 128k</i> syntax is deprecated and will stop working soon.</li>
+ <li> <i>-map_chapters</i> now takes only an input file index and applies to
+ the next output file. This is consistent with how all the other options
+ work.</li>
+ <li> <i>-map_metadata</i> now takes only an input metadata specifier and
+ applies to the next output file. Output metadata specifier is now part of
+ the option name, similarly to the AVOptions/map/codec feature above.</li>
+ <li> Presets in <b>avconv</b> are disabled, because only libx264 used them
+ and presets for libx264 can now be specified using a private option
<i>-preset
+ presetname</i>.</li>
+</ul>
