Hello. I'm trying to make a tiny mci multimedia player. This is the very-very-very first version though operative. You can open a midi-mp3-wav-etc file and then play it, also stop and reanude it, and can demand a looping play of it. At least en W7 works fine... more or less. I need to insert a beep at the end of the file to reanude it from the begining, need to fix it.
I want to implement it a basic ... don't know how to name it... graphic bar guided by the music?. One status bar (I think it is not so hard), and one volume bar (not hard neither). And an avi player (not hard). The more difficult could be the first one.
In short. Any info about that?
By the way, 512Kb of size is a bit low limit... :redface:
Regards,
alfonso
you can probably just use a "slider" aka trackbar - somewhat similar to a scrollbar

if you want to use CreateWindowEx, you can use the predefined system class:
szTrkBarClass db 'msctls_trackbar32',0
A very good one is VLC.His author said that he is good because he don't use API as you do.

The mediaobj.h(.sdk) is part of the windows sdk
Perhaps wincodecsdk.h(.sdk) could help in this.
You need direct access to the audio buffer to create a sound bar or oscilloscope. Is this possible with the MCI api ?
You can do this if you use ACM-codecs.
Hello, thank you all for your responses. I've been a few days on hollidays and didn't watch them. I've had few time to work on the program, but it already has several interesting features: we already know how long is the file we are playing and for what position we are, hence it would be easy to add a track bar.
In the other hand, it can play several formats, including films avi, you can check it. Also can play in a loop if you click in the 8th button (loop icon) or just one time if you click it once again.
Nevertheless, i have to control better when the file ends playing and polish many things.
Also, i'd like to add an oscilloscope bar, but this seems to be not so easy to implement, though this is a main point to me because, controlling this, can be used in demos for sincronizing graphics and sounds.
My objective is not to make a multimedia player in the usual way, just play a bit with sound programming.
I think that it is amazing you can make a simply (but functional) multimedia player in a few kilo bytes.
Regards
a spectrum analyzer would be a nice feature (rather than an oscilloscope)
i bet Marinus has some code for that :t
Ever thought of using directsound ?
It's easy to set up and you have full control of the sounddata in the sound buffers.
With a bit of timing stuff you can draw a scope or whatever and synchronise graphics etc.
Lately i was busy programming a (ACM codec) mp3 player, wich is a pain in the a**. There are so many corrupt mp3 files that crashed my proggy.
So i made a little proggy to analyze the mp3 files to find the errors and correct them on the fly so they could play in my proggy or else skip the song.
It's fun to watch graphics that reacts to the music. :biggrin:
Hello. Track bars added but not fully functional, and any other minor changes.
Regards
Alfonso,
works fine under Windows 7-64. The language is Spanish, isn't it?
Gunther
Yes, it is.
Flat buttons seem to be more stylish than 3d ones :icon_rolleyes:
Hi,
Works for MP3 and WAV files under Windows 2000. An AVI
file opened, but did not play (I think). Looks a bit odd though.
Attached is a screen shot of it.
Cheers,
Steve N.
Mp3 Wav and Avi play well under Windows 8.1 64 bit.
My aim is to make a multimedia player as tiny as i can, doing the minimum win api calls, so i made icons using system fonts webdings and wingdings, but i can see that not everybody has them... :biggrin: Systems fonts size can take effect too :biggrin:
:( :redface: :(
One way to fix it should be using images, but this will increase the exe size...
The aspect of the window should be this one (didn't show the imagen in the zip???):
Thank you for your help,
alfonso
Playing so far: avi, wmv, wma, mp3, mp4, flv, aif
Windows 8.1 Pro with Media Center, also shark007's codec pack probably helps :biggrin:
Thank you sinsi. Everybody sees the player as i attached before? I see that FORTRANS can not, maybe he has not any of the fonts used... It should be a pity to have using images instead of fonts, though only increases in 11 kb the size of the exe, maybe even less. :idea:
Regards
Same as attached picture here.
Hello, some changes done
Now buttons work as expected: open, play/pause, stop, sequential/repeat, info. The others do nothing for now.
Tooltip changes in buttons with double function when is due, also in volume track bar.
Track bars work fine:
* status bar follows the playing position and you can interactuate with it for positioning the playing where you want.
* volume bar works fine, but the order to mci don't.
ToDo list:
* Add spectrum analyzer. Will we achieve to synchronize it with music?
* Add play list.
* Get into live buttons that for now don't work
* Make the file name oscillate in its field in status bar when doesn't fit
* Change font icons for image icons. It will increase in some kb the resulting size
* Polish the code.
Other:
* I have noticed that in some cases the file length returned by mci is not right
* It seems that mp3 are followed in milliseconds but films don't ???
Thank you all,
alfonso

I don't know. I will try it
It would be nice to see the source code for this player
A chance to educate!

that would be nice. You should perhaps it integrate in your tutorials. Only an idea.
Gunther
That's the idea. A tuto on sound programming... phewww, much work. If everything works and have time. Does anyone want to participate? Here's a preview of the spectrum analizer. Now "just" get it work.
Hi avcaballero,
If it's ok with you, i'll make a minimalistic example with an oscilloscope and a spectrum analyzer.
For that i'm gonna use DirectSound for the music and Direct3D9 for the graphics.
Did search for getting access via MCI to the raw audio data but, couldn't find anything.
To keep it simple, the program will load a .WAV file ( 16 bit, Stereo, 44100 sample rate )
Think i need a week or so to write it.....
Yes, it's very ok to me. If you like, i will include into the tuto and credit you as the author with your nickname, or real name, what you want, otherwise it would be nice to me just for learn.
Source code would be nice, but even better if it is accompanied by some explained notes. Will your code be masm? When i have time, or anybody else who wants, would translate it to nasmx/fasm/tinyc.
My aim is to make a tuto on sound, in the whole as i can, ie, midi, wavs, mp3, etc with differents ways of playing them (not only mci, but direct sound, playsound, etc, revive old dos crappy sounds, etc). This will require threads. I'd like to write code to play mods/xm, in a simply way, just for play them in demos/games.
Very important, synchronizing sounds and graphics.
I don't have previous experience with none of them, i'm learning as i a program.
So, very much things to do, so if any one want to contribute with code/explanation would be welcome.
Regards.
Yes, it will be written in MASM.
The sound data will be converted to a 32 bit floating point sound buffer so we can do some fast SIMD coding.
For the spectrum analyzer i'll use FIR bandpass filters for each frequency band we want to show on the screen.
The graphics will be synchronized to the screen refresh rate and the sound playing at that moment.
I'll try to keep it as simple as possible ( no fancy speed tricks etc.... )

Hi avcaballero,
Just found an old ( very bad ) modplayer routine on my old harddisk.
This was an attempt to make a Protracker the same as on the Amiga. :biggrin:
Never finished it......

Thank you, Marinus, very valuable example :t.... I've got "Unable to create Direct3D Object" though.
Check the dependencies , some DX DLLs may be missing from your computer.
I cheated. Spectrum works... randomly, not with the music :biggrin:
I've been playing a bit with this and i think that FFT is needed, that wouldn't be the problem in principle. To implement this formula we need to know samples, i guess that samples per second. I believe that we can retrieve this information from mci using "status" with a string like this:
status mymci audio samplespersec notify
But i'm not sure, the prooves that i made give me values such as 16,776,960. Would we need to divide it by 1000?
FFT seems to be a bit slow, and when i have used it every second, the program crashed after a while. Maybe would be needed creating a thread to calculate this, and maybe not every second... ?
Any idea?
Thank you
i would try to aim for 4, 8, or maybe even 16 updates per second
Just synchronize to the screen refresh rate.
Let's say you have a screen refresh rate of 60 Hz and play the music at a sample rate of 44100 Hz.
Then you have 44100 / 60 = 735 audio samples per frame to use with your spectrum.
Now trigger the screen update and calculate the position in the audio buffer.
Important is to use all samples to present a full spectrum.
If you want to use FFT then you can cheat and do a 512 samples FFT discarding the remaining 223 samples.
You will lose spectrum information...
Or you do a 1024 samples FFT and fill it with the 735 audio samples and 289 null samples.
Now you get the full spectrum information out of the 735 audio samples.
Because the audio data stream is continue, it is not important how often you present your spectrum to the screen.
for example 30 times a second, then you have to process 1470 audio samples at once.
Alfonso, did you find a way to get access to the MCI audio buffer?
B.T.W. there are many ways to show the frequency spectrum.
for example: FFT DFT Goertzel IIR
And the FIR method i'm working on now. ( need a couple of more days to complete it )
Quote from: Siekmanski on August 18, 2014, 05:08:45 AM
Alfonso, did you find a way to get access to the MCI audio buffer?
No. I'm studying MCI documentation and proving. There're many labels, much stuff, but poorly documented and very few resources in the net.
As i said before, it is possible that "status" mci command with some of its labels may help us, but i need prove.

Hi avcabalero,
This is how far i am now...
Wrote a timer interrupt which polls every 5 milliseconds the play cursor of the soundcard.
It's a double buffer system, 1 buffer is playing while the other buffer is filled with new audio data.
Fast sample type conversion from 16bit signed to float32 and vice versa is done with SSE2.
Drawing to the screen is done with Direct3D9 vertex programming.
As you can see i synchronized the audio that is playing with the oscilloscope on the screen.
You can load 44100 Hz 16bit stereo music wav files to test it.
In the attachment is a little wav sample.
This weekend i planned to implement the FIR audio spectrum analyzer.
When it's finished i will include all the source codes with some comments how things are done.
Marinus
It has an excellent look, Marinus. I'm going a bit slowly, but keep on going and hope to have some news soon.
Thanks a lot.
Alfonso
Hi Marinus,
looks good. :t

that looks more like an oscilloscope :biggrin:

Dave,
excuse me, but an oscilloscope looks a bit different. :lol:
Gunther
Thanks Alfonso and Gunther.
Hi Dave,
Quotethat looks more like an oscilloscope :biggrin:
Yes, but what's a spectrum analyzer without an oscilloscope. :biggrin: :biggrin:
The spectrum analyzer will be below the oscilloscope, in this case just as in Alfonso's request a 10 bar 1 octave pass band filter.
This weekend i hope to have it finnished.
Marinus
i have some idea what an oscilloscope looks like - lol
sometimes, i feel like i have one attached to my hip
a couple of the images above show linear divisions for frequency
for RF work, that's usually desirable (we want the sidebands to appear linear)
but, the audio spectrum might be best divided into log divisions
each band doesn't have to be an octave
let's say we want to cover 2 to 20,000 Hz in 12 bands
the width for each would be (20000/2)1/12 = 2.1544346900318837217592935665194
so, the bands would be
2 to 4.309 Hz
4.309 to 9.283 Hz
9.283 to 20 Hz
20 to 43.09 Hz
43.09 to 92.83 Hz
92.83 to 200 Hz
200 to 430.9 Hz
430.9 to 928.3 Hz
928.3 to 2000 Hz
2 to 4.309 KHz
4.309 to 9.283 KHz
9.283 to 20 KHz
probably, 20 to 20,000 is more common - i'll let you do the math :P
the vertical scale is also log (decibels)

Hello, here's my source code. I didn't achieve get the spectrum analyzer work yet.
What i have tried is the next:
* Line 225. [call WaveIn_Inicio]
Open de waveIn device to retrieve wave data from whatever the kind of music that mci were playing
* Line 300. [CreateThread RecogeWaveData]
In the TrimSpectrum timer we execute the recovering wave data that has the next subroutines:
- WaveIn_Rellena. Retrieves wave data from the device opened. This is the heart of the though, but is too slow and no effective. Commented, but it is needed to get it working.
- doFFT2. What the name says, second version.
- clcLongBarrasEspectro. Calculates the length of the spectrum analyzer. This data will go to the vbEspectro array. Ten fields of byte values (16 maximum).
I have no much time to work on it, so any help would be nice :). I think that i'm near, but the waveIn device seems to be too slow, there must be another way or something to makes it work.
Regards
Thank you Alfonso. :t
Gunther
I have fixed a couple of things, now i don't allow start filling the wavein buffer before it has been filled plenty before. The motion of the spectrum analyzer bars are due now to the wave in device. Surely they needed to apply some reduction factor, i don't worry about that. The main problem is that the wavein buffer is filled up very slowly. I can't believe it, there must be anything wrong.
In the other hand, i believe that there's a rawdata label for mci command. Other land to explore...
Regards
Hi Alfonso,
take a look at the source code of the directX of UFMod here: http://ufmod.sourceforge.net
It don´t seems to be that hard to port and it works as expected. Maybe it can help you fix on your own Bars (The example on dx uses only 2 channles of audio, but the filling of the bitmaps for them are simply gdi usage).
The functions that you may use are:
FillVUBars
RedrawVU
RedrawTimeP
All inside play_ds.c
Thank you, guga, i'll have a look, though i first wanted to make mci working, ufmod surely read directly from file, and i don't know yet if mci offers that lovely feature ::) . When i have finished what i want to do/learn with mci i will start with directx/maybe external dlls like ufmod or others.
Regards.
I`m currently also working on UFMod. Although it can be assembled in Masm as it is, the library is deeply confused. But, it works for mci as well (not only dx or openAI). It was biased on FMod, but the russian author is really insane :icon_mrgreen: :icon_mrgreen:
I´m trying to port it as a dll (or as a library, if i suceed to convert to RosAsm and later convert it to masm with JJ tool RosAsm2Masm) and fixing whatever i can be able to understand from that. But, if you plan to rewrite the asm version of UfMod, get ready, because it is a pain to do.

Yes, I'm afraid so :biggrin:, i'll settle with a few things
Hello there, i noticed yesterday that the process of my program wasted many resources... hmmm a bit strange. What i want so many data for at the same time? Now, spectrum analyzer works fluently using wavein device inside some logical values. Nevertheless the bars motion appears to be a bit chaotic yet, i think that i have to calibrate the fft function. We will see...
Regards
Great work.
But, the spectrum analyser is static here in WinXp. I mean, the bars shows up, but don´t move
:biggrin: that's another history. You have to set the wave in device activated, as you want to talk to microphone. Ie, it is a little fudge for not to have reading directly from the audio file. Maybe would be possible to do a bypass directly to the WaveIn device, but I haven't got such high expectations, for the moment I settle for get it working.
Well done, Alfonso. :t
Gunther
It took me a bit longer to write, sorry Alfonso.
But i have rewritten everything to make things more flexible.
Also included a fresh written routine to calculate the FIR coefficients for low pass, high pass, band pass and band reject filters with a Hamming window.
Very handy timing routines and fast sample type conversion routines.
I'll comment and explain as much as possible and rename labels and text from Dutch to English. :biggrin:
When i'm ready i will post all the source code and maybe open a new thread to explain some stuff if you guys are interested.
I know that there are other ways to do spectrum analyzers but you can do a lot of nice things with FIR filters.
Here is the exe with a 1 octave 10 band analyzer and 2 short wav samples.
Just load your favorite wav file and enjoy watching the music. :eusa_dance:
There is maybe 1 thing of which i'm not certain, that is the Direct3d9 code.
I've kept it very minimal so i hope it works on other PC as well.
You will need at least a PC with SSE2 ( didn't include a test.... )
Excelent work Siekmanski

Hello, Gunther. I don't remember exactly the error message. It was relative to Direct3D and the application never showed up. I will go there again some day and prove again. Does it work fine for everybody else in WXP? Maybe any library missed in those pc. I will check it in an vb xp...
It seems that standard wxp needs extra libraries.

Hello, this is the new version, i think it works quite well now. But, of course, we need to turn on the wave-in device to get the wave format of what we are playing. Hence, i wonder if it is possible making it work regardless of it is on or off to obtain this precious wave info.
Regards
Alfonso,
what's the reason for the new version? Bug fixes?
Gunther
No, in previous versions, spectrum analyzer didn't work well, ie at the rhythm of music. Now you can notice that bars move according to music, more visible when goes from top to down and vice versa.
Previously, when music was ending and sound was down, bars was up. Now, i believe that bars works better.
The hard thing to do is using wave-in device even if it were off, or use any other way to get the wave info.
Regards.
Works fine under Windows 7-64.
