OKay so I've spent a good hour trying but still nothing is working. First time working with DllCallBack, so hopefully one of you gurus can see where my problem lies. What I would like to achieve is playing of a MP3 file located in a remote location or an internet radio using bass.dll.

Here is my code:

;       Pointer to the downloaded data... NULL = finished downloading. 
;   length
;       The number of bytes in the buffer... 0 = HTTP or ICY tags.

;       The user instance data given when BASS_StreamCreateURL was called.

;HSTREAM BASS_StreamCreateURL(
;   char *url,
;   DWORD offset,
;   DWORD flags,
;   DOWNLOADPROC *proc,
;   void *user
;)

;WHats what....
;   url 
;       URL of the file to stream. Should begin with "http://" or "ftp://". 
;
;   offset
;       File position to start streaming from. This is ignored by some servers, specifically when the length is unknown/undefined.
;
;   flags Any combination of these flags.
;       BASS_SAMPLE_FLOAT
;            Use 32-bit floating-point sample data. See Floating-point channels for info.  
;       BASS_SAMPLE_MONO
;            Decode/play the stream (MP3/MP2/MP1 only) in mono, reducing the CPU usage (if it was originally stereo). This flag is automatically applied if BASS_DEVICE_MONO was specified when calling BASS_Init.  
;       BASS_SAMPLE_SOFTWARE
;            Force the stream to not use hardware mixing.  
;       BASS_SAMPLE_3D
;            Enable 3D functionality. This requires that the BASS_DEVICE_3D flag was specified when calling BASS_Init, and the stream must be mono. The SPEAKER flags can not be used together with this flag.  
;       BASS_SAMPLE_LOOP
;            Loop the file. This flag can be toggled at any time using BASS_ChannelFlags. This flag is ignored when streaming in blocks (BASS_STREAM_BLOCK).  
;       BASS_SAMPLE_FX
;           requires DirectX 8 or above Enable the old implementation of DirectX 8 effects. See the DX8 effect implementations section for details. Use BASS_ChannelSetFX to add effects to the stream.  
;       BASS_STREAM_RESTRATE
;            Restrict the download rate of the file to the rate required to sustain playback. If this flag is not used, then the file will be downloaded as quickly as the user's internet connection allows.  
;       BASS_STREAM_BLOCK
;            Download and play the file in smaller chunks, instead of downloading the entire file to memory. Uses a lot less memory than otherwise, but it's not possible to seek or loop the stream; once it's ended, the file must be opened again to play it again. This flag will automatically be applied when the file length is unknown, for example with Shout/Icecast streams. This flag also has the effect of restricting the download rate.  
;       BASS_STREAM_STATUS
;            Pass status info (HTTP/ICY tags) from the server to the DOWNLOADPROC callback during connection. This can be useful to determine the reason for a failure.  
;       BASS_STREAM_AUTOFREE
;            Automatically free the stream when playback ends.  
;       BASS_STREAM_DECODE
;            Decode the sample data, without playing it. Use BASS_ChannelGetData to retrieve decoded sample data. The BASS_SAMPLE_3D, BASS_STREAM_AUTOFREE and SPEAKER flags can not be used together with this flag. The BASS_SAMPLE_SOFTWARE and BASS_SAMPLE_FX flags are also ignored.  
;       BASS_SPEAKER_xxx
;            Speaker assignment flags. These flags have no effect when the stream is more than stereo.  
;
;   proc 
;       Callback function to receive the file as it is downloaded... NULL = no callback. 
;   user
;       User instance data to pass to the callback function.

And here is 1 example for using the CallBack in the function in some other language (Stream an MP3 file, and save a local copy.)

FILE *file=NULL;
...
void CALLBACK downproc(void *buffer, DWORD length, void *user)
{
    if (!file) file=fopen("afile.mp3", "wb"); // create the file
    if (!buffer) fclose(file); // finished downloading
    else fwrite(buffer, 1, length, file);
}
...
HSTREAM stream=BASS_StreamCreateURL("http://www.asite.com/afile.mp3", 0, 0, &downproc, 0);

BASS_StreamCreateURL Example (Stream an MP3 file.)

HSTREAM stream=BASS_StreamCreateURL("http://www.asite.com/afile.mp3", 0, 0, NULL, 0);

Thanks for any help, I greatly appreciate it.

Cheers,

Brett

I made changes to your dllcallbackregister, dllcall lines (you had used "unint64" but should have used "dword"), and to the test function which needed an extra parameter. This must be getting very close.

Well, in theory, this is right, but AutoIt crashes after a few secinds, when doing anything in the callback function Or the stream just hangs because AutoIt is too slow... Write the CallBack in e.g. FreeBasci and all should work >_<

Edit: The uint64 is wrong this must always be DWORD ! Also, it would be better to use hwnd for the stream Handles.

Hey All,

Bumping this topic, as it has started to crash, mostly after around 20 seconds max.

Any ideas?

Cheers,

Brett

EDIT:

Current code is in the first post. You will need BASS.au3 which is in my signature... Well it will be in a moment...

I think, the AutoIt-Interpreter is too slow for the callbacks of BASS.dll... Propably BASS has to wait too long and then crashes because the resources arent used correctly

[Kragen]

Is my computer fucked, or is the download link broken?

[BrettF]

What download link?

[trancexx]

The everlasting dilemma.
