|[in] hEnc||Handle to the encoder|
|[in] pStream||stream buffer, required to possess a stream metadata|
|[in] isPrefix||Discriminate between prefix and suffix SEI|
|[in] iPayloadType||SEI payload type. See Annex D.3 of ITU-T [in] pPayload. Raw data of the SEI payload|
|[in] iPayloadSize||Size of the raw data payload|
|[in] iTempId||Temporal id of the raw data payload|
Add an SEI to the stream This function should be called after the encoder has encoded the bitstream. The maximum final size of the SEI in the stream cannot exceed 2Ko. The SEI payload does not need to be anti emulated, this is done by the Encoder.
Returns section id.
