For instance, in one example, a method includes initiating, by a first computing device, a connection to a second computing device, selecting, by the first computing device, a codec for encoding data into a data stream, wherein the codec is selected such that the data stream can be decoded by the second computing device without being transcoded by an intermediary, encoding, by the first computing device, the data into the data stream using the codec, and sending, by the first computing device, the data stream to the second computing device. ## Claims ### Claim 1 A method, comprising: initiating, by a first computing device, a connection to a second computing device; selecting, by the first computing device, a codec for encoding data into a data stream, wherein the codec is selected such that the data stream can be decoded by the second computing device without being transcoded by an intermediary; encoding, by the first computing device, the data into the data stream using the codec; and sending, by the first computing device, the data stream to the second computing device. ### Claim 2 (depends on 1) The method of claim 1, wherein the selecting comprises: consulting, by the first computing device, a profile for the second computing device in a set of contacts stored on the first computing device; and retrieving, by the first computing device, the codec from the profile. ### Claim 3 (depends on 2) The method of claim 2, wherein the codec is a codec that the first computing device has used in conjunction with a past connection to the second computing device. ### Claim 4 (depends on 1) The method of claim 1, wherein the selecting comprises: consulting, by the first computing device, a remote repository of connection parameters for a profile for the second computing device; and retrieving, by the first computing device, the codec from the profile. ### Claim 5 (depends on 1) The method of claim 1, wherein the selecting comprises: negotiating, by the first computing device, the codec with the second computing device. ### Claim 6 (depends on 1) The method of claim 1, wherein the codec is stored in a set of codecs on the first computing device. ### Claim 7 (depends on 1) The method of claim 1, further comprising: downloading, by the first computing device, the codec from a remote repository of codecs stored in a content delivery network to which the first computing device and the second computing device are connected. ### Claim 8 (depends on 7) The method of claim 7, wherein the remote repository of codecs is shared among a pool of customers including an operator of the first computing device and an operator of the second computing device. ### Claim 9 (depends on 7) The method of claim 7, wherein the remote repository of codecs loads the codec to the first computing device based on an observation that the first computing device and the second computing device have communicated with a common set of contacts. ### Claim 10 (depends on 1) The method of claim 1, wherein the codec is selected based upon aggregate resources present across a path between the first computing device and the second computing device. ### Claim 11 (depends on 1) The method of claim 1, wherein the second computing device opts in to use the codec prior to the sending. ### Claim 12 A computer-readable medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising: initiating, by a first computing device, a connection to a second computing device; selecting, by the first computing device, a codec for encoding data into a data stream, wherein the codec is selected such that the data stream can be decoded by the second computing device without being transcoded by an intermediary; encoding, by the first computing device, the data into the data stream using the codec; and sending, by the first computing device, the data stream to the second computing device. ### Claim 13 (depends on 12) The computer-readable medium of claim 12, wherein the selecting comprises: consulting, by the first computing device, a profile for the second computing device in a set of contacts stored on the first computing device; and retrieving, by the first computing device, the codec from the profile. ### Claim 14 (depends on 13) The computer-readable medium of claim 13, wherein the codec is a codec that the first computing device has used in conjunction with a past connection to the second computing device. ### Claim 15 (depends on 12) The computer-readable medium of claim 12, wherein the selecting comprises: consulting, by the first computing device, a remote repository of connection parameters for a profile for the second computing device; and retrieving, by the first computing device, the codec from the profile. ### Claim 16 (depends on 12) The computer-readable medium of claim 12, wherein the codec is stored in a set of codecs on the first computing device. ### Claim 17 (depends on 12) The computer-readable medium of claim 12, further comprising: downloading, by the first computing device, the codec from a remote repository of codecs stored in a content delivery network to which the first computing device and the second computing device are connected. ### Claim 18 A method, comprising: initiating, by a first computing device, a connection to a second computing device; selecting, by the first computing device, a codec for encoding data into a data stream, wherein the codec is selected such that the data stream can be decoded by the second computing device without being transcoded by a lossy transcoder; encoding, by the first computing device, the data into the data stream using the codec; and sending, by the first computing device, the data stream to the second computing device. ### Claim 19 (depends on 18) The method of claim 18, wherein the data stream is transcoded by a lossless transcoder after being sent by the first computing device, but prior to being received by the second computing device. ### Claim 20 (depends on 18) The method of claim 18, wherein the selecting comprises: consulting, by the first computing device, a profile for the second computing device in a set of contacts stored on the first computing device; and retrieving, by the first computing device, the codec from the profile.
