5.40.1 Function Documentation
5.40.1.1 on2sc Flix2_AddFilter (FLIX2PLGNHANDLE ∗ pPlgn, const FLIX2HANDLE flix, const
char ∗ plgn_name)
Add a filter to the encoder’s filter chain.
Initializes a FLIX2PLGNHANDLE mapped to plgn_name for use in subsequent filter calls.
Parameters:
→ pPlgn Storage location to receive the value of the created FLIX2PLGNHANDLE
← flix Handle to the flix engine returned from Flix2_Create() or Flix2_CreateEx()
← plgn_name Name of the filter to add to the chain
Return values:
ON2_OK the engine successfully added the filter and initialized a FLIX2PLGNHANDLE for use in
filter related functions.
ON2_INVALID_PARAMS should one or more of the preconditions fail
ON2_NO_MEM memory could not be allocated for the FLIX2PLGNHANDLE
