Member Function Documentation
◆ close()
|
overridevirtual |
This function will be called just before destruction of the StreamWriter object and no other calls (except destructor) will follow.
Implements nx::sdk::cloud_storage::IStreamWriter.
◆ locationUrl()
|
overridevirtual |
Returns last location of where data has been written. It's not location of an individual media chunk, but general physical storage location. This url should be passed later to the DeviceAgent::createStreamReader when requesting this media chunk for reading later.
Implements nx::sdk::cloud_storage::IStreamWriter.
◆ putData()
|
overridevirtual |
Write a data packet. Implementation is discouraged to buffer packets. Instead, it should block until the data is completely processed.
packet->channelNumber() corresponds to ICodecInfo::channelNumber() i.e. if packet->type() == dptVideo && packet->channelNumber() == 1, then CodecInfo with mediaType == AVMEDIA_TYPE_VIDEO && channelNumber == 1 can be used to process this packet.
If packet->type() == dptAudio && packet->channelNumber() == 0, then CodecInfo with mediaType == AVMEDIA_TYPE_AUDIO && channelNumber == 0 can be used to process this packet.
If packet->type() == dptData && packet->channelNumber() == 0, then CodecInfo with mediaType == AVMEDIA_TYPE_DATA && channelNumber == 0 can be used to process this packet.
Implements nx::sdk::cloud_storage::IStreamWriter.
◆ size()
|
overridevirtual |
Total size of written data so far.
Implements nx::sdk::cloud_storage::IStreamWriter.
