Which allocated memory units do I have to free manually; which are freed by calls to the OSS API functions?

The general rule is: Any memory that you allocate yourself, you have to also free yourself. On the other hand, if you let an OSS API function allocate memory for you, you can call one of the provided OSS API memory deallocating functions (e.g., ossFreeBuf() and ossFreePDU()) to free up the memory. This general rule applies to both the encoder and decoder output buffers.

The samples included with some of the Knowledge Center answers are meant for your general understanding of the OSS products. Different versions of the products might produce slightly different outputs. Consult the products documentation and samples for the most up-to-date products information and code examples.
