You now label each registered buffer with a frame_number_tag . When Bink finishes decoding, it calls your sync_callback with that tag. This allows triple-buffered async decode without polling.
: Bink typically requires two full YUV12 video buffers in memory at playback time.
While powerful, bink register frame buffer8 new comes with caveats:
The term "Frame Buffer 8" likely denotes two overlapping features in Bink’s history. First, it references the mode. In many 5th and 6th generation consoles, video memory was scarce. Bink could decode video into an 8-bit indexed frame buffer, where each pixel was a single byte indexing a 256-color palette. The codec then leveraged the console’s hardware color lookup table (CLUT) to display 24-bit color without storing full RGB per pixel. This “Frame Buffer 8” mode cut memory bandwidth and storage by 66% compared to 24-bit buffers. Second, “8” hints at Bink’s core transform block size: the codec processes frames in 8×8 pixel blocks using a variant of the DCT (discrete cosine transform) or simple differential coding. By aligning operations to 8-byte or 8-pixel boundaries, Bink maximized cache line usage and register file efficiency on CPUs like the PowerPC 750 or MIPS R5900.
The Bink Register Frame Buffer call is a critical step in the Bink SDK workflow. It informs the Bink decoder about the specific memory layout of the buffers you provide. Instead of the decoder allocating its own memory, this function allows developers to point Bink to pre-allocated textures or system memory.
