<p>Codec Config Buffer Flag: OMX_BUFFERFLAG_CODECCONFIG is an optional flag that is set by an output port when all bytes in the buffer form part or all of a set of codec specific configuration data.

Any component that for a given stream sets OMX_BUFFERFLAG_CODECCONFIG shall not mix codec configuration bytes with frame data in the same buffer, and shall send all buffers containing codec configuration bytes before any buffers containing frame data that those configurations bytes describe. If the stream format for a particular codec has a frame specific header at the start of each frame, for example OMX_AUDIO_CodingMP3 or OMX_AUDIO_CodingAAC in ADTS mode, then these shall be presented as normal without setting OMX_BUFFERFLAG_CODECCONFIG. </p>

The starting timestamp corresponds to the first data that should be displayed at startup or after a seek. The first timestamp of the stream is not necessarily the start time. For instance, in the case of a seek to a particular video frame, the target frame may be an interframe. Thus the first buffer of the stream will be the intra-frame preceding the target frame and the starttime will occur with the target frame (with any other required frames required to reconstruct the target intervening).</p>
