The Video Format Bridge core uses the user-selected VC and Data Type information to filter only the required AXI4-Stream data beats. This AXI4-Stream data is further processed based on the Data Type information and the output is based on the requested number of pixels per clock. The output interface adheres to the protocol defined in the AXI4-Stream Video IP and System Design Guide (UG934) [Ref 2] .

The Video Format Bridge core processes the data type selected in the Vivado Integrated Design Environment (IDE) and filters out all other data types except for RAW8 and User Defined Byte-based Data types (0x30 to 0x37) received from the CSI-2 RX Controller.

Irrespective of the Vivado IDE selection, RAW8 and User Defined Byte-based Data types are always processed by the Video Format Bridge core. This allows multiple data-type support, one main data-type from the Vivado IDE for pixel data and a User Defined Byte-based Data type for metadata. When multiple data types are transferred (for example, RAW10 and User Defined Byte-based Data) the actual placement pixel data bits are defined in the AXI4-Stream Video IP and System Design Guide (UG934) [Ref 2] .

For unaligned transfers there is no way to specify the partial final output (TKEEP) for the output interface. Ensure that you take this into consideration and discard the unintended bytes in the last beats when there are un-aligned transfers.
