[Libav-user] avio_close_dyn_buf + av_free != freed memory

[Isaac Wang]

I'm currently using avio_close_dyn_buf to grab the data out of an 
AVIOContext object into uint8_t * buffer.  Once I am done using the 
data, I try to free the buffer with av_free(buffer), but the memory 
doesn't get freed.  Over time, my program runs out of memory and 
crashes.  Can anyone help shed some light?
