int write_nal_unit (  h264_stream_t *  h,
uint8_t *  buf,
int  size
) 
 

Write a NAL unit to a byte buffer. The NAL which is written out has a type determined by h->nal and data which comes from other fields within h depending on its type.

Parameters:
[in,out] h the stream object
[out] buf the buffer
[in] size the size of the buffer
Returns:
the length of data actually written
