[Libav-user] avpicture_alloc returns error -12 at frame 308

[jim morgenstern]

Application using ffmpeg to read and write QT files.  C++, Win 7.

 

First 300+ calls to avpicture_alloc succeed; then the next one returns error
despite valid parameters in function call:

{

             AVPicture* reformatFrame = new AVPicture;

              ap = avpicture_alloc( reformatFrame, iPxfmt, nss, nlines);

 

in same module, after processing reformatFrame it gets released:

                    avpicture_free(reformatFrame);

                    delete reformatFrame;

             }

 

When it fails, the return code, ap, is -12

 

Smells like a memory leak, though.  I run vld [visual lead detector] and it
does not report any memory leaks.

 

Any ideas where to look?  What would -12 mean ??
