encoder wrapper
>The better solution should be: use av_malloc and just memset the padding bytes.
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);
