UNIVERSAL_process - max nb of inBufs

Hi,

when using Codec Engine version 2.25.01 and a IUNIVERSAL algo - in UNIVERSAL_process:

UNIVERSAL_process(

triggerphase_codec_handle,

&inBufs, &outBufs,

NULL,

(UNIVERSAL_InArgs *) &inArgs,

(UNIVERSAL_OutArgs *) &outArgs);

whats the maximum number of inBufs? I set inBufs.numBufs to 31 - and UNIVERSAL_process fails. If I set it to 1 - it succeeds!

This is the log when it fails:

The input and output params are XDM1_BufDesc structures defined in xdm.h:

#define XDM_MAX_IO_BUFFERS 16 /**< Max I/O Buffers */

...

typedef struct XDM1_BufDesc {
    XDAS_Int32   numBufs;   /**< Number of buffers in @c descs array.
                             *
                             *   @remarks Must be less than
                             *             #XDM_MAX_IO_BUFFERS.
                             */
    XDM1_SingleBufDesc descs[XDM_MAX_IO_BUFFERS]; /** Array of buffer
                             * descriptors.
                             */
} XDM1_BufDesc;
