Abstract
Exemplary embodiments relate to techniques for dynamically selecting codecs as video is transmitted in real time. In some embodiments, a first codec initially encodes video data, and a second codec is evaluated to replace the first codec. The system switches to the second codec only if an increased amount of power consumption resulting from using the second codec balances with a correspondingly sufficient increase in the quality of the video encoded by the second codec. In some embodiments, codecs are excluded from consideration if it is determined that the local device does not have sufficient processing resources to operate the codec, or if a mismatch is detected between the codec operating on a sending device and a codec operating on a receiving device.
