Classes
struct	DRMPRIME::DmaBufIdentity
	Identifies a frame's memory and layout across file descriptor reuse. More...

Namespaces
namespace	DRMPRIME

Typedefs
using	DRMPRIME::StatInodeFn = std::function<bool(int fd, uint64_t& inode)>
	Writes the dma-buf inode for fd; false on failure.

Functions
bool	DRMPRIME::StatInode (int fd, uint64_t &inode)
std::optional< DmaBufIdentity >	DRMPRIME::GetDmaBufIdentity (const AVDRMFrameDescriptor *descriptor, uint32_t width, uint32_t height)
	Identity of descriptor layer[0] only; nbLayers is keyed, layers 1+ are not inspected: a consumer that reads layers 1+ must not key on this identity. Returns nullopt for a missing or malformed descriptor or an unreadable inode.
std::optional< DmaBufIdentity >	DRMPRIME::GetDmaBufIdentity (const AVDRMFrameDescriptor *descriptor, uint32_t width, uint32_t height, const StatInodeFn &statInode)
	Test seam: same, with an injectable stat function.
