[FFmpeg-devel] av_open_input_file memory leak?

[Emanuele Fumagalli]

I read "Reporting a Bug To The FFmpeg Project" and I think I'm in the right 
mailing list for posting this, otherwise redirect me to another forum.
As suggested I uploaded the example file and txt in Mplayer/Incoming/Memory 
leak open_input.

I reproduced the memory leak with these lines of code:

av_register_all();
AVFormatContext* m_context;
for(int i = 0; i < 100; i++)
{
av_open_input_file(&m_context, "c:\\sheryl.mp4.001", 0, 0, NULL);
if (m_context)
{
    av_close_input_file(m_context);
    m_context = NULL;
}

If the file is complete(with full header) no memory leak, if the file is 
truncated at the beginning not preserving entire header I get memory leak of 
around 5 Mb at each av_open_input_file.

Is that a memory leak or I'm missing something?

Thanks
