)
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_sizeByte length of each length code
sample_bufferNAL units prefixed with length codes.
seiOptional A53 closed captions SEI data.
dst_dataMust be zeroed before calling this function. Contains the copied NAL units prefixed with start codes when the function returns successfully.
dst_sizeLength of dst_data
Returns
0 on success AVERROR_INVALIDDATA if length_code_size is invalid AVERROR_BUFFER_TOO_SMALL if dst_data is too small or if a length_code in src_data specifies data beyond the end of its buffer.
