|

|
<P>Fontos tisztázni egy elterjedt tévhitet. Amikor az emberek egy <B>.AVI</B>
|
||||||
|
kiterjesztésû file-t látnak, azonnal azt mondják hogy az nem MPEG file.
|
||||||
|
Ez nem igaz. Legalábbis nem ebben a formában. Ha azt mondod nekik hogy ez
|
||||||
|
a file tartalmazhat MPEG videot is, kinevetnek. Nyugodtan verd bucira
|
||||||
|
a fejüket, és küldd el õket RTFM-be.</P>
|
||||||
|
|
||||||
|
<P>Ugyanis, a <B>codec</B> nem egyenlõ a <B>file formátummal</B>.<BR>
|
||||||
|
A video <B>codec-ek</B> például a következõk: MPEG1, MPEG2, DivX, Indeo5, 3ivx.<BR>
|
||||||
|
És a video <B>formátumok</B>: MPG, VOB, AVI, ASF.<BR>
|
||||||
|
</P>
|
||||||
|
|
||||||
|
<P>Elméletben nyugodt szívvel beletehetsz OpenDivX videot és MP3 audiot
|
||||||
|
egy <B>.MPG</B> formátumú file-ba. Annyi a probléma hogy a legtöbb lejátsz
|
||||||
|
nem fogja lejátszani, mert MPEG1 videot és MP2 audiot várnak (az <B>.MPG</B>-ben
|
||||||
|
nem lehet megadni hogy milyen formátumban van benne a video és audio, mint
|
||||||
|
például az <B>.AVI</B>-ban). Van tegyél MPEG1 videot .AVI-ba. Például az
|
||||||
|
<A HREF="http://ffmpeg.sourceforge.net">ffmpeg</A> tud ilyen fileokat
|
||||||
|
létrehozni.</P>
|
||||||
|
|
||||||
|
<P>Audionál a <B>codec</B> és <B>formátum</B> gyakorlatilag ugyanazt
|
||||||
|
jelenti.</P>

<P>
|

|
<LI>MPG : this is the most <B>basic</B> form of MPEG file formats. Contains
|
||||||
|
MPEG1 video, and MP2 audio.</LI>
|
||||||
|
<LI>VOB : this is the MPEG file format on <B>DVD</B>s. Contains optionally
|
||||||
|
encoded MPEG2 video, and usually AC3 audio.<BR>
|
||||||
|
<B>Read the <A HREF="cd-dvd.html#4.2">DVD section</A> !</B></LI>
|
||||||
|
<LI>DAT : this is the MPEG file format on <B>Video CD</B>s. It's the same
|
||||||
|
as the MPG, but due to the nature VCDs are created and Linux is designed,
|
||||||
|
the DAT files can't be played nor copied from VCDs. You have to use the
|
||||||
|
<CODE>-vcd</CODE> option to play the VideoCD.</LI>
|
||||||
|
</P>
|
||||||
|
|
||||||
|
<P>One important feature for MPGs is that they have a field to describe
|
||||||
|
the aspect ratio of the video stream within. For example SVCDs have
|
||||||
|
480x480 resolution video, and in the header that field is set to 4:3, so
|
||||||
|
it's played at 640x480. AVI files don't have this field, so one has to
|
||||||
|
scale it during encoding.</P>

<P><B><A NAME=2.1.1.2>2.1.1.2. AVI file-ok</A></B></P>
|
||||||
|
|
||||||
|
<P>Designed by Micro$oft, the <B>AVI (Audio Video Interleaved)</B> is a
|
||||||
|
widespread multipurpose format, currently used mostly for DivX and DivX4
|
||||||
|
videos. Has many known drawbacks, and inabilities (for example in streaming).
|
||||||
|
Has support for one video stream, and 99 audio streams. Can be as big as
|
||||||
|
2Gb. There exists an extension for it to be bigger, called <B>OpenDMS</B>.
|
||||||
|
M$ currently strongly discourages its use and propagates ASF/WMV. Not if
|
||||||
|
anybody cares.<BR>
|
||||||
|
<B>NOTE</B> : DV cameras can create two types of AVI format, one is the usual and
|
||||||
|
playable, the other is neither.</P>
|
||||||
|
|
||||||
|
|
||||||
|
<P><B><A NAME=2.1.1.3>2.1.1.3. ASF/WMV file-ok</A></B></P>
|
||||||
|
|
||||||
|
<P>ASF is a new very undocumented fileformat from M$, and WMV is its
|
||||||
|
successor. They are very commercial, and anyone who writes an opensource
|
||||||
|
parser for them, soon meets certain doom. While creating the parser, it
|
||||||
|
was obvious to see how bulky, shit, and unusable they are. Not if anybody
|
||||||
|
would expect something else from M$.

||||||
|
|
||||||
|

||||||
|
<P><B><A NAME=2.1.1.4>2.1.1.4. QT/MOV file-ok</A></B></P>
|
||||||
|
|
||||||
|
<P>They are Apple's formats. Not much to say, basically well designed,
|
||||||
|
multipurpose, streamable, many features etc. Kinda hard to find documentation,
|
||||||
|
but we think the parser is perfect.

||||||

<P><B><A NAME=2.1.1.5>2.1.1.5. VIV file-ok</A></B></P>
|
||||||
|
|
||||||
|
<P>Hey this is new code in <B>MPlayer</B>, be gentle! Seeking is
|
||||||
|
currently nonexistent, audio too. TODO : complete this section.</P>
|
||||||
|
|
||||||
|
|
||||||
|
<P><B><A NAME=2.1.2>2.1.2. Audio formátumok</A></B></P>
|
||||||
|
|
||||||
|
<P>Currently <B>MPlayer</B> is still a <B>Movie</B> and not a <B>Media</B>
|
||||||
|
player, thus the pure audio formats (for example MP3, WAV, audio ASF) are
|
||||||
|
unplayable. Use <A HREF="http://www.xmms.org">xmms</A>, <A HREF="http://www.mpg123.de">mpg123</A>
|
||||||
|
or whatever.</P>
