2.1. Támogatott formátumok

+ +

Az MPlayer a következő egységeket/formátumokat ismeri :
+

+ +

Megjegyzés: realmedia-val (.ra/.rm) kapcsolatban lásd a FAQ-t!

+ +

Fontos tisztázni egy elterjedt tévhitet. Amikor az emberek egy .AVI +kiterjesztésű 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 őket RTFM-be.

+ +

Ugyanis, a codec nem egyenlő a file formátummal.
+A video codec-ek például a következők: MPEG1, MPEG2, DivX, Indeo5, 3ivx.
+És a video formátumok: MPG, VOB, AVI, ASF.
+

+ +

Elméletben nyugodt szívvel beletehetsz OpenDivX videot és MP3 audiot +egy .MPG formátumú file-ba. Annyi a probléma hogy a legtöbb lejátsz +nem fogja lejátszani, mert MPEG1 videot és MP2 audiot várnak (az .MPG-ben +nem lehet megadni hogy milyen formátumban van benne a video és audio, mint +például az .AVI-ban). Van tegyél MPEG1 videot .AVI-ba. Például az +ffmpeg tud ilyen fileokat +létrehozni.

+ +

Audionál a codec és formátum gyakorlatilag ugyanazt +jelenti.

+ + +

2.1.1. Video formátumok

+ + +

2.1.1.1. MPG, VOB, DAT file-ok

+ +

+

  • MPG : this is the most basic form of MPEG file formats. Contains +MPEG1 video, and MP2 audio.
    • +
  • VOB : this is the MPEG file format on DVDs. Contains optionally +encoded MPEG2 video, and usually AC3 audio.
    +Read the DVD section !
    • +
  • DAT : this is the MPEG file format on Video CDs. 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 +-vcd option to play the VideoCD.
    • +

    + +

    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.

    + + +

    2.1.1.2. AVI file-ok

    + +

    Designed by Micro$oft, the AVI (Audio Video Interleaved) is a +widespread multipurpose format, currently used mostly for DivX and DivX4 +videos. Has many known drawbacks, and inabilities (for example in streaming). +Has support for one video stream, and 99 audio streams. Can be as big as +2Gb. There exists an extension for it to be bigger, called OpenDMS. +M$ currently strongly discourages its use and propagates ASF/WMV. Not if +anybody cares.
    +NOTE : DV cameras can create two types of AVI format, one is the usual and +playable, the other is neither.

    + + +

    2.1.1.3. ASF/WMV file-ok

    + +

    ASF is a new very undocumented fileformat from M$, and WMV is its +successor. They are very commercial, and anyone who writes an opensource +parser for them, soon meets certain doom. While creating the parser, it +was obvious to see how bulky, shit, and unusable they are. Not if anybody +would expect something else from M$. + + +

    2.1.1.4. QT/MOV file-ok

    + +

    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. + +

    2.1.1.5. VIV file-ok

    + +

    Hey this is new code in MPlayer, be gentle! Seeking is +currently nonexistent, audio too. TODO : complete this section.

    + + +

    2.1.2. Audio formátumok

    + +

    Currently MPlayer is still a Movie and not a Media +player, thus the pure audio formats (for example MP3, WAV, audio ASF) are +unplayable. Use xmms, mpg123 +or whatever.
