That is low efficiency and slow as James mentioned. You don't need to set the 
whole buffer to be zero, only padding bytes needed.

The memset inside av_mallocv sets the whole buffer of the size 
"avctx->extradata_size + AV_INPUT_BUFFER_PADDING_SIZE" to zero.

avctx->extradata_size = header_ptr->nFilledLen;
avctx->extradata = av_mallocz(avctx->extradata_size + 
AV_INPUT_BUFFER_PADDING_SIZE);

The better solution should be: use av_malloc and just memset the padding bytes.

Hi Almer,

Thanks for the review! Indeed the explicit memset() is redundant and I have 
removed that.

void *av_mallocz(size_t size)
{
void *ptr = av_malloc(size);
if (ptr)
memset(ptr, 0, size);
return ptr;
}

You used av_mallocz() to allocate the buffer, so it's already fully zeroed.

In any case, it would be faster to instead use av_malloc() above, then
only zero the padding bytes here. Since you're copying the actual data
in the line below, nothing will remain uninitialized.
