The AVI container is the native container format for
|
||||
<application>MEncoder</application>, which means that it's the one that

is best handled, and the one for which <application>MEncoder</application>
|
||||
was designed.
|

As noted above, other container formats are usable, but you may
|

experience some problems when using them.

As you can see, <systemitem class="library">libavformat</systemitem>
|
||||
allows <application>MEncoder</application> to mux into a considerable
|
||||
variety of containers.
|
||||
Unfortunately, as <application>MEncoder</application> was not designed
|
||||
from the beginning to support other container formats than AVI,
|
||||
your should really be paranoid about the resulting file.
|
||||
Please check to be sure that the audio/video synchronization is okay
|
||||
and that the file can be played correctly by players other than
|
||||
<application>MPlayer</application>.
