void Image::Indeo::avFreeP (void *arg)
 Free a memory block which has been allocated with a function of av_malloc() or av_realloc() family, and set the pointer pointing to it to `NULL`.
void * Image::Indeo::avReallocF (void *ptr, size_t nelem, size_t elsize)
 Allocate, reallocate, or free a block of memory.
uint16 Image::Indeo::invertBits (uint16 val, int nbits)
 Reverse "nbits" bits of the value "val" and return the result in the least significant bits.
uint32 Image::Indeo::bitswap32 (uint32 x)
 Swap the order of the bytes in the passed value.
uint8 Image::Indeo::avClipUint8 (int a)
 Clip a signed integer value into the 0-255 range.
unsigned Image::Indeo::avClipUintp2 (int a, int p)
 Clip a signed integer to an unsigned power of two range.
