I am trying to wrap aac encoder and decoder codecs (they came with the
ipp sample) into DirectShow filters. I need to understand the
"precharging" of the decoder. According to a document from Apple(
their AAC streams have 2112 samples of audio to precharge the decoder.
Since we will support loop play, shuffle forward/backword, I need to
understand how Intel IPP codecs deal with this precharging issue. Is
there precharging needed? The encoded AAC streams has extra data at the
beginning and the end of the bit streams?
Any information and pointers will be very helpful. Thanks.
