Comment (by er.anshul.maheshwari@…):
It is not the case of multiple av_frame_free
I placed break point at av_frame_free and saw all frames memory address,
address that is given to av_free_frame when it gives segmentation fault is
not matching to previous allocated frame memory.
$352 = (AVFrame **) 0xbfffe7d0
353-421 repeat same memory
$424 = (AVFrame **) 0xbfffe7d0
$425 = (AVFrame **) 0x9500954
$426 = (AVFrame **) 0x9501e14
$427 = (AVFrame **) 0x9501db4
