Abstract: An example device for decoding media data includes a memory configured to store the media data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine whether two or more decoder instances are intended to be synchronized. The one or more processors are configured to, based on the two or more decoder instances being intended to be synchronized, control the two or more decoder instances so as to enable rendering of decoded data from each of the two or more decoder instances at a same presentation time.

Abstract: Example in-band delay measurement techniques are described. An example first computing device transmits, to a second computing device, a first data packet, the first data packet including a first time indicator and at least one header extension element. The at least one header extension element includes a header extension element header, the header extension element header having a length of at least one byte. The first computing device receives, from the second computing device, a second data packet, the second data packet including a second time indicator. The first computing device determines a data packet delay associated with the first data packet based on the first time indicator and the second time indicator and transmits an indication of the data packet delay to at least one of the second computing device or a third computing device.
