Subject: [libav-user] libavcodec - Memory allocation problem in DLL
Hi, All,
I've created pretty simple DLL, based on api-example. It uses FLV1 codec.
All works fine unless I use ANY memory allocation in the _main_program_. I
tried several approaches and now I suppose that something is wrong within
the DLL. DLL has no explicit entry point and uses malloc() to get memory
for picture_buf and outbuf. It all was done just as it was shown in
api-example.c.
My question is - where could be the problem?
Maybe I must to make any explicit memory manager initialization in the
DLL?
Or does MINGW do it for me internally?
The AV occures here:
out_size = avcodec_encode_video(c, outbuf, out_size, picture);
It says "read of address "0xffffffff". And it only occurs if I insert ANY
dummy GetMem() in my main project, which is calling this DLL. Main project
is written in Delphi 7.
Any ideas?
Best regards,
Alex
