This article mainly explains "what are the command line parameters of DOS multimedia player MPXPLAY". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "what are the command line parameters of the DOS multimedia player MPXPLAY?"

MPXPLAY.EXE [options] File name or list of files to play / convert

Playlist:

-@ PLAYLIST: playlist file (such as M3U, MXU, etc.)

-@ d PLAYLIST: click mode (put the list of files to be played on the left, that is, put the song in the queue)

-@ s PLAYLIST.M3U: save the edited playlist to the list file (default is MPXPLAY.M3U)

-@ sw PLAYLIST.M3U: save the playlist in EXTM3U format (like Winamp format)

-@ sx PLAYLIST.MXU: save the playlist in an extended format (playlist with file information)

-ds DRIVES: detect multiple drives (such as:-ds cde-> detect c: d: e: drives) (- ds cde * .wav-> find only WAV files)

-dd uses click mode (load files to the left) (used when detecting drives (- ds) and directory browsers)

-prn random playback

-prn2 starts by randomizing playlists

-pre playback / repeat playlist

-pre1 replays / repeats only one song (back to the beginning of the file)

-pss NUM: start playing (starting with the first song num)

-pst TIME: starts playback (from playback time TIME) (TIME can be in HH:MM:SS or MM:SS or SSS format (e.g. 3:17 or 197))

-psf NUM: starts playback (from the playback position NUM)

-psp NUM: play from the NUM-16% position of the song (16% is the beginning of the song)

-psc NUM: exit when playing to the location of the song NUM

-ptc TIME: duration of playback (in a song) (TIME can be in HH:MM:SS or MM:SS or SSS format)

-pfc NUM: only play NUM playback positions

-pef NUM: exit when playing to the location of the song NUM (cannot be used with the-psp option)

-phs hi-lite scan: each song is only played for 10 seconds (1m00s-1m10s) (can be configured with the-psf,-pst,-pfc,-ptc option)

-pap enables automatic pause (i.e. automatic pause before each song)

Display:

-f0 no screen output

-ff displays only the current playback position and the actual file name

-fl displays only one line of output

-v detailed mode (including media information, ID3 tag information, when the-f0mam quoffjpfl option is specified)

-fe full-screen playlist editor (no spectral simulator and browser)

-fs single line count mode (that is, do not change the screen to 50 line mode at run time) (25-> 50)

-db disables the catalog browser (left) in the playlist editor (if used, the program will exit after the last song)

-db2 has directory browsers on both sides (that is, on the left and right sides)

-ebs num: the size of the editor and directory browser box (1-64) (default: 64)

Input buffering (default is 128 (4'32) bytes of pre-buffering, no interrupt decoding):

-bn has no input buffering (not recommended)

-bp input file pre-buffering (decoder runs in interrupt signal)

-bl input all buffers (load the whole song into memory before playing (maximum is 13m))

-bni disables interrupt decoding (for-bl option)

-bn8 prohibits the use of all int08 functions (interrupt decoding, DMA monitor)

-bbn pre-buffer block (for-bp option) (1 block = 32 kilobytes) (using: 8-64 (MP3-WAV)) (default: 4;-bp: 32)

Sound card and output:

-scs CARD manually select sound card (S16pjr ESS Magi WSS Magi gus Magi SBP Magi MID Magol nul)

-sct CARD sound card testing (if no CARD parameter is specified, all possible / detected sound cards will be automatically tested and displayed)

-scm manually sets MIDAS and saves it in the MPXMIDAS.INI file (MIDAS has been cancelled because it does not work)

-scv num sets the sound card volume (main volume and pcm volume at the same time) (1-100 (%)) (some sound cards in Win9x use 100% (for example, SB Live/Audigy sound card))

-sctr num sets the treble volume of the sound card (1-100 (%)) (for old SB16 (OPL) and AWE32/64 sound cards only, 50 means no change)

-scbs num sets the bass volume of the sound card (1-100 (%)) (for old SB16 (OPL) and AWE32/64 sound cards only, 50 means no change)

-ddma dual DMA (32k-> 64k) (sound card buffer)

-o write pcm data to the wav file (instead of playing it through the sound card)

-of num sets the output frequency (using a constant sound card conversion frequency when exporting to wav files)

-oc num sets the output channel (for output to wav files only) (channel 1 or 2)

-ob num sets the input bit (for output to wav files only) (if the input (wav file) and output (wav file) are greater than 16 bits (such as 24732 bits), the-hq option is recommended.

-t test mode (that is, do not really output sound, but do various other operations)

Sound adjustment and output modification:

-Volume setting (enlarged) in sv volnum software (default: 100 (%))

-sva [volnum] automatically adjust volume [use initial volume value]

-sr surnum surround / stereo amplifier (default: 100 (%) = no surround sound, 10 = mono, 150 = wide stereo)

-sp speed playback speed (frequency) control (60-200) (default: 100 (%))

-sl limit sound limit (playback limit) (0-200) (default: 20)

-cl decodes only the left channel (1.9x/1.4x times faster when decoding MP3/OGG files)

-cm downmix channel (stereo to mono) (1.7x faster when decoding MP3 files)

-hq hq (floating) Mixer + Virtual loudness when playing MP2 files

-cf automatically converts smoothness at the end of the file

-cfp [num] smooth transition point (default is 120) (the smooth transition starts from the playback position num, relative to the beginning of the fade)

-cfo [num] fade length (default is 250)

-cfi [num] fade length (default is 200)

-cfl [num] smooth transition limit (default is 0) (starts smooth conversion when the volume is less than numb (no smooth transition point is used)

-cft [num] smooth conversion type (default is 1) (0 bit: fade out, 1 bit: fade in) (- cft 3: fade in + fade out)

(smooth conversion only:-cfo 150-cfp 0-cfi 150, fade in & fade out only:-cfo 150-cfp 150-cfi 100)

ID3 information and file information:

-inl does not preload file information (including file headers, id3 tags) (loaded at the beginning of the file)

-ipl loads information while playing

-idl loads only the information of the files displayed (that is, the files displayed in the playlist editor)

-in does not load the id3 tag information of the file (that is, only the file header information is loaded) (but the-il option works)

-8 convert characters in tags (author, title, etc.) (its Win character / DOS character setting can be configured in mpxplay.ini)

-8U enable UTF-8 text decoding in tags (MP3,MPC,OGG is also OK, but the OGG standard is better)

-8cp CPNAME: the target code page for UTF-8 decoding (CPNAME can be: ISO-8859-1 (standard US-ASCII) and ISO-8859-2 (default))

-8uv validates (only uses) Win characters in decoding of UTF-8 (codes above ASCII 128s)

ID3 list:

-il [information file] load partial id3 information list file (for current folder items, reload each time the folder changes)

-ig [information file] load the global id3 information list file (for items in the playlist) (establish: mpxplay-@ playlist.m3u-is d:listfile.txt-ist 448)

-is [Information File] Save id3 information to list file

-iw [information file] writes the id3 tag to the media file (mp2,mp3,mpc) (loads it from the information file) (the default [information file] name is:! FILES)

-io NUM sorts playlists (0 by title, 1 by author, 2 by album, 3 by year, 4 by annotation, 5 by style / category of song, 6 by track number, 7 by time, 9 by file name, 10 by full path and file name, 11 by file name only

-ist NUM specifies the type of id3 save list (the type varies with the num bit) (default: 63)

Bit 0 (+ 1): lists the folder name

Bit 1 (+ 2): lists the file name

No. 2 (+ 4): how the author-title is listed (non-fixed / fixed position)

Bit 3 (+ 8): the time when the file is listed

Bit 4 (+ 16): list bit rate (kilobytes / second)

Bit 5 (+ 32): lists the file size (megabytes)

Bit 6 (+ 64): lists the full path to the file

Other:

-x PRGNAME: sets the program name used when SHELL to DOS (for example,-x nc.exe)

-xs: automatically SHELL to DOS when MPXPLAY is started

-xr: TSR method (for CDW audio files only) (for example, 'mpxplay.exe-bl-xr-xs-pre1 song.mp3' will be played continuously in the background)

-xas: enable the soft shutdown feature of the ATX/APM power supply (on exit)

Keyboard control (some keys are case-sensitive (that is, only lowercase!)

(it is recommended that the keyboard rate in BIOS be set to 30 characters per second):

ESC-quit

F10-exit

CTRL-C-quit

Gray-backward a song from the playlist

Gray -'+'- advance a song from the playlist

White -'-'- go backwards like a CD player (that is, if the playback position is greater than 38, go back to the beginning of the song, otherwise go back to the previous song)

Gray -'/'- back a folder (an album) in the playlist

Gray -'*'- advance a folder (an album) in the playlist

->-(right button head) advance 50 playback positions (which can be configured through SeekFrames in mpxplay.ini. 50 playback positions are usually 1.3 seconds)

-4x fast forward (200 playback positions)
