static

Copies NAL units and replaces length codes with H.264 Annex B start codes.

On failure, the contents of dst_data may have been modified.

Parameters

length_code_size	Byte length of each length code
sample_buffer	NAL units prefixed with length codes.
sei	Optional A53 closed captions SEI data.
dst_data	Must be zeroed before calling this function. Contains the copied NAL units prefixed with start codes when the function returns successfully.
