Functions 9

fnint dmabufMemoryGetFd(gst.memory.Memory mem)Return the file descriptor associated with mem.

fngst.memory.Memory drmDumbMemoryExportDmabuf(gst.memory.Memory mem)Exports a DMABuf from the DRM Bumb buffer object. One can check if this feature is supported using [gstallocators.drmdumb_allocator.DRMDumbAllocator.hasPrimeExport];

fnuint drmDumbMemoryGetHandle(gst.memory.Memory mem)Return the DRM buffer object handle associated with mem.

fnint fdMemoryGetFd(gst.memory.Memory mem)Get the fd from mem. Call [gstallocators.global.isFdMemory] to check if mem has an fd.

fnbool isDmabufMemory(gst.memory.Memory mem)Check if mem is dmabuf memory.

fnbool isDrmDumbMemory(gst.memory.Memory mem)

fnbool isFdMemory(gst.memory.Memory mem)Check if mem is memory backed by an fd

fnbool isPhysMemory(gst.memory.Memory mem)

fnsize_t physMemoryGetPhysAddr(gst.memory.Memory mem)
