Title : Save AVI with Sound
Author : jfk EO-11110
Posted : 1+ years ago

Description : Like the framegrabber this one is using AviFil32.dll and some of the codecs listed in the codec selection box won't work. I also guess MP3 won't work for the sound, better use a standard WAV file.
Some things may be not implemented 100% correctly, although it worked on my machine. Thanks to the PB Community where I have found most of the infos needed for this.

Have fun, Mr. Next-Industrial-Light-and-Magic.

 Memoey Access Violation on RtlMoveMemory2


Hambone(Posted 1+ years ago)

 MAke sure you read the comments and put the decls in the right place:avifil32.decls and kernel32.decls are in the comments.Allan


John Blackledge(Posted 1+ years ago)

 Yes, I did.Then had to comment out RtlMoveMemory2 because it was already in another lib <sigh>,So does that mean that the other RtlMoveMemory2 definition is different from yours?


CS_TBL(Posted 1+ years ago)

 also important: can we expect a bmax port?


RGR(Posted 1+ years ago)

 @ JohnRTLMoveMemory is indeed a critical functionThere are 3 of them "on the market" (_from _to _ex)They differ only in the way the parameters are provided (Pointers and/or Variables). I just looked it up a minute ago because I had a MAV using the FreeImage.dll that was mentioned here 1 month ago ;-)


jfk EO-11110(Posted 1+ years ago)

 the only diffrence is: if you use a bank pointer (a*) or a plain int (a). So blitz will decide how it's handled. In kernel32.dll it's the same function.If this RtlMoveMemory2 isn't compatible with the one that is already in use by one of your userlibs, then off course you only have to rename it in the source and the kernel32.decls userlib mentioned in the code. Or you may use one of your existing declarations. Only make sure the pointers are used correctly:RtlMoveMemoryWhatever%( bank* ,source_adr,len) : "RtlMoveMemory"The star (*) is important.<div class="quote"> also important: can we expect a bmax port? </div>Maybe you should do that, all your contributions to the community are welcome. However, they sell those tongue cleaners .


Matty(Posted 1+ years ago)

 I realise this is an old code archive entry, but I am seeking some assistance in how to get it to work.I've put the decls in place, yet when I try to run the program (the small included demo in the listing above), I get an MAV (no extra info supplied even in Debug mode) on the following line:(line 184)

Code Select Expand

If AVISaveOptions(hwnd, 3, 1, ret, plpOptionsList)=1 ;=0




Matty(Posted 1+ years ago)

 anyone?


Warner(Posted 1+ years ago)

 Here the code runs fine. Are you on Vista? I believe that line executes a dialog in which the user can select what compressor should be used.Maybe you can omit this problem by changing these lines to:

Code Select Expand

;;;If AVISaveOptions(hwnd, 3, 1, ret, plpOptionsList)=1 ;=0
res=AVIMakeCompressedStream(compression_handle, stream_handle, 0, 0)



Matty(Posted 1+ years ago)

 Thanks Warner I'll give it a try, I'm on XP though.


Matty(Posted 1+ years ago)

 Sorry, still didn't work, no debugging errors either.  I'll give up on this one I think...


Gladclef - Ben B(Posted 1+ years ago)

 Well, I don't know if anyone's paying attention to this anymore, but I'm having difficulties with this line:If AVISaveOptions(hwnd, 3, 1, ret, plpOptionsList)=1


jfk EO-11110(Posted 1+ years ago)

 I just see this, sorry ppl. Tho I don't know what your problem is with the code, there yould be several reasons:-Microsofts Implementation of AviFile Api lacks of compatibility (rather unlikely)-Security Management prevent it from working (eg. DEP)-Incompatible with other DECLS files (likely). To test this, save all decls in a backup folder, then delete everything but the ones used by this code.Also: there is the bank plpOptionsList, try to make it bigger for debugging purpose:   plpOptionsList=CreateBank(80000) ; req. size guessed, but hey...Seems like I didn't know exactly what I'm doing there :)Finally, try not to compare it against 1, but agains <>0 instead:If AVISaveOptions(hwnd, 3, 1, ret, plpOptionsList)<>0 [/i]
