[Libav-user] Cleaning AVFrame properly

[Venkateswaran.S]

Hi all,

I'm creating AVFrame object using av_frame_alloc() function and clearing it
using av_frame_free(&frame) which internally calls av_frame_unref(), but
it's not cleaning the memory properly. Heap size of my app grows
exponentially in run time.

As far as I know, av_frame_alloc() calls av_freep() which calls av_free()
to free the dynamic memory. Memory gets cleaned, If I use
av_free(frame->data[0]) directly instead of av_frame_free(&free)
