2.6.9 IBMDStreamingAudioPacket Interface¶

The IBMDStreamingAudioPacket interface represents an audio packet.

Objects with an IBMDStreamingAudioPacket interface are passed to the IBMDStreamingH264InputCallback::H264AudioPacketArrived() callback.

The audio packet can contain compressed audio, such as MPEG-2 AAC audio, which can be passed to a suitable audio decoder for decoding and playback.

For some applications it may be more convenient to process audio packets instead of processing audio carried in transport stream packets.

2.6.9.1 IBMDStreamingAudioPacket::GetCodec method¶

BMDStreamingAudioCodec IBMDStreamingAudioPacket::GetCodec();¶

The GetCodec method returns the codec describing the audio in the packet.

Returns:: The codec for the audio in the packet.

2.6.9.2 IBMDStreamingAudioPacket::GetPayloadSize method¶

long IBMDStreamingAudioPacket::GetPayloadSize();¶

The GetPayloadSize method gets the number of bytes in the audio packet.

Returns:: Audio packet size in bytes.

2.6.9.3 IBMDStreamingAudioPacket::GetBytes method¶

HRESULT IBMDStreamingAudioPacket::GetBytes(void **buffer);¶

The GetBytes method returns a pointer to the data buffer of the audio packet.

Parameters:

buffer – Pointer to audio packet data buffer - only valid while object remains valid.

Return values:

E_POINTER – The buffer parameter is invalid
S_OK – Success

2.6.9.4 IBMDStreamingAudioPacket::GetPlayTime method¶

HRESULT IBMDStreamingAudioPacket::GetPlayTime(uint64_t requestedTimeScale, uint64_t *playTime);¶

The GetPlayTime method returns the time at which to playback the audio contained in the audio packet. The play time is in units of the requested time scale.
