Direct VCD/SVCD/DVD mode
in this mode encode2mpeg creates an mpeg stream, then a binary image
and finally burns
the image on the selectred support (CD or DVD). You don't need to
execute all the steps, you can only create the mpeg stream or the
binary image.
A more detailed view fo the first block is showed below; mpeg2enc is
used to
create the mpeg video stream from a yuv4mpeg stream generated by
MPlayer. The audio stream can be mp2, mp3, ac3 or lpcm. Different tools
can be used for this purpose: mp2enc, toolame, lame, MEncoder
(libavcodec).
Direct mode
is the defaul mode. If you do not select a specific mpeg profile a
VCD is created. The profile options are:
-vcd
-svcd <1-2>
-dvd <1-5>
The argument of -svcd selects the following resolutions:
n
|
PAL
|
NTSC
|
|
1
|
480x576
|
480x480
|
(default)

|
352x240
|

The argument of -dvd selects the following resolutions:

|
PAL
|

Common options
The following options can be used with every profile:
-abr <n> (audio bit rate, default 224/mp2, 128/mp3, 448/ac3-6ch,
192/ac3-2ch )
-asr <n> (audio sample rate, defaul 44100/mp2-mp3, 48000/ac3-lpcm)
-vfr <1-8> (video frame rate, defaul is 4/NTSC, 3/PAL)
-n <n|p|s> (video norm, it's better to always specify the norm
because
it selects appropriate default values for other parameters)
-mp2 <mp2enc|toolame|mencoder|copy> (choose mp2 audio and use the
specified tool)
-mp3 <lame|mencoder|copy> (choose mp3 audio and use the specified
tool)
-ac3 <mencoder|copy> (choose ac3 audio and use the specified tool)
-lpcm (choose lpcm audio)
-qmatrix <kvcd|tmpgenc|default|hi-res> (select custom
quantization matrices: this can reduces the size of the mpeg stream)
-mpegchannels <1-6> (number of channels of the audio stream, 1-6
for ac3/lpcm, 1-2 for mp2/mp3)
-normalize (apply normalize to the audio stream)
-volume <n> (change the amplitude of the audio stream)
-noscale (tell yuvscaler to not rescale the video stream to
VCD/SVCD/DVD frame
size. Usefull if you want to use mplayer scale filter for scaling)
-monochrome
-split <n> (split the resulting video in n MB chunk, defaul 800)
-nosplit (do not split the mpeg stream, defaul is to split)
-imageonly (create the mpeg stream and the binary image, but don't burn
it)
-mpegonly (create only the mpeg stream)
-streamonly (create only the elementary video and audio stream without
multiplexing them)
-cpu <1-8> (number of threads)
-addchapter <time,time,...|copy> (insert chapters at specified
time, or copy the chapers structure from a DVD)
-mpegfixaspect <pad|crop> (force the aspect ratio of the
source video to match the one specified with -a)
-nowait (do not ask for a keypress before starting the burning process)
VCD
For the vcd profile you can specify the following options:
-a <1-3> (aspect ratio, defaul 2)
-vbr <n> (video bitrate, default 1152)
-mpeg1vbr (generate an mpeg1 variable video bit rate stream. Not all
the hardware players can play such VCD)
-mp2 <mp2enc|toolame|mencoder|copy> (create an mp2 audio stream
with the selected tool, default mp2enc)
-mp3 <lame|mencoder|copy> (create an mp3 audio stream with the
selected tool, default lame)
-blank (blank a cd before burning)
-cdi <path to CD-i application files> (add CD-i compatibility)
SVCD
-a <2-3> (aspect ratio, defaul 2)
-vbr <n> (video bitrate, default 2500)
-mp2 <mp2enc|toolame|mencoder|copy> (create an mp2 audio stream
with the selected tool, default mp2enc)
-mp3 <lame|mencoder|copy> (create an mp3 audio stream with the
selected tool, default lame)
-ac3 <mencoder|copy> (create an ac3 audio stream with the
selected tool, default mencoder)
-lpcm (create an uncompressed lpcm audio stream [48000 or 96000 kHz])
-multiaudio "aid0 aid1 ..." (output mpeg stream with several audio
streams)
-p (play the movie as NTSC video using 3:2 pulldown, -vfr 1
-p creates a smaller stream than -vfr 4)
-blank (blank a cd before burning)
-addsub <sid,sid,...> (copy the specified subtitle stream)
-svcdht (enable the VCD header trick, see http://www.videohelp.com/svcd)
DVD
-a <1-4> (aspect ratio, defaul 2)
-vbr <n> (video bitrate, default 7500)
-mp2 <mp2enc|toolame|mencoder|copy> (create an mp2 audio stream
with the selected tool, default mp2enc)
-mp3 <lame|mencoder|copy> (create an mp3 audio stream with the
selected tool, default lame)
-ac3 <mencoder|copy> (create an ac3 audio stream with the
selected tool, default mencoder)
-lpcm (create an uncompressed lpcm audio stream [48000 or 96000 kHz])
-multiaudio "aid0 aid1 ..." (mpeg stream with several audio streams)
-p (play the movie as NTSC video using 3:2 pulldown, -vfr 1
-p creates a smaller stream than -vfr 4)
-dvdaudiolang <code,code,...> (ISO 639 langauges codes)
-addsub <sid,sid,...> (copy the specified subtitle stream)
Limitations
Direct VCD/SVCD/DVD mode doesn't handle correctly video that has a
source frame rate different from the one of the final mpeg stream. This
includes source video with variable frame rate, video with non standard
frame rate (like 15 fps), and, sometimes, NTSC videos. PAL -> NTSC
or
NTSC -> PAL conversion is therefore not possible in this mode.
Examples
