GstAllocatorFlags

The allocator has a custom alloc function. Only elements designed to work with this allocator should be using it, other elements should ignore it from allocation propositions. This implies gst.types.AllocatorFlags.NoCopy.

When copying a #GstMemory allocated with this allocator, the copy will instead be allocated using the default allocator. Use this when allocating a new memory is an heavy opperation that should only be done with a #GstBufferPool for example.

first flag that can be used for custom purposes
