[Libav-user] 答复: Errors when creating a C++ object (with a C API) in FFmpeg filter

I hope to build the new library in a standalone one which can be used in ffmpeg filter and can also be used independent on ffmpeg (with some wrapper). So, I let it depend on openCV only.
It now looks like if I create it (by explicitly calling "new ..."), and if there is another struct in ffmpeg filter which is allocated by av_malloc after I create my object, there will be a memory issue. But if I create alone, or allocate the struct alone, there is no memory issue. So, both of them cannot be used at the same time.

Why didn't you use the existing opencv filter in FFmpeg?
