Integrating audio and video conferencing capabilities
Systems, methods, and computer-readable storage media for adding video to an audio only communication session. During a communication session between a first device and a second device, the first device receives an audio portion of the communication session from a user. The first device then receives, via a wireless connection, a video portion of the communication session from a third device. The first device synchronizes the audio portion of the communication session and the video portion of the communication session to yield a synchronized audio and video portion of the communication session. Next, the first device sends the synchronized audio and video portion of the communication session to the second device.

6. The method of claim 1 , wherein the third device comprises a video decoder and encoder, a camera, and a video output, and wherein the audio portion and the video portion of the audio video communication session are both transmitted via a same network associated with the wireless connection.
7. The method of claim 1 , further comprising:
receiving, from a fourth device, a second video portion of the audio video communication session when the first device is outside of a wireless range of the third device;
synchronizing the second video portion of the audio video communication session and a corresponding audio portion of the audio video communication session to yield a second synchronized audio and video portion of the audio video communication session, wherein the corresponding audio portion is associated with the first device; and
sending the second synchronized audio and video portion of the audio video communication session to the second device.
8. The method of claim 1 , wherein the first device is a WIFI direct enabled phone, and wherein the wireless connection is a WIFI direct connection.
9. A system comprising:
a processor; and
a computer-readable storage medium storing instructions which, when executed by the processor, cause the processor to perform operations comprising:
establishing, via a wireless connection, an audio only communication session between a first device and a second device;
adding video capabilities to the audio only communication session by sending a message to a third device having video capabilities, the message requesting initialization of video input and output to yield an audio video communication session;
receiving, via the wireless connection, a video portion and an audio portion of the audio video communication session;
synchronizing the audio portion of the audio video communication session and the video portion of the audio video communication session to yield a synchronization of the audio and video portion of the audio video communication session; and
based on the synchronization, sending the video portion of the audio video communication session to a video output component at the third device and the audio portion of the audio video communication session to an audio output at the first device so as to expand capabilities of the audio only communication session from audio only to both audio and video.
10. The system of claim 9 , wherein the first device is a WIFI direct enabled phone and the wireless connection is a WIFI direct connection, and wherein the audio portion and the video portion of the audio video communication session are both transmitted via a same network associated with the wireless connection.
11. The system of claim 9 , wherein the computer-readable storage medium stores additional instructions which result in operations further comprising:
receiving audio for the audio video communication session via the first device, the audio originating from a user.
12. The system of claim 9 , wherein the computer-readable storage medium stores additional instructions which result in operations further comprising:
receiving video frames associated with the audio video communication session;
checking lip synchronization attributes on the video frames;
at a time that is based at least in part on the lip synchronization attributes, sending the video frames to the third device to be decoded and displayed at the third device; and
at the time that is based at least in part on the lip synchronization attributes, sending audio frames received for the audio video communication session to an audio output component on the first device, the audio frames being associated with the video frames.
13. The system of claim 9 , wherein the video portion of the audio video communication session comprises compressed video frames captured by a camera associated with the third device.
14. The system of claim 9 , wherein the third device comprises a video decoder and encoder, a camera, and a video output.
15. The system of claim 9 , wherein synchronizing the audio portion of the audio video communication session and the video portion of the audio video communication session comprises setting lip synchronization attributes on the video portion of the audio video communication session with audio from the audio portion of the audio video communication session.
16. A non-transitory computer-readable storage medium storing instructions which, when executed by a processor, cause the processor to perform operations comprising:
establishing, via a wireless connection, an audio only communication session between a first device and a second device;
adding video capabilities to the audio only communication session by sending a message to a third device having video capabilities, the message requesting initialization of video input and output to yield a video audio communication session;
receiving, via the wireless connection, a video portion and an audio portion of the audio video communication session;
synchronizing the audio portion of the audio video communication session and the video portion of the audio video communication session to yield a synchronization of the audio and video portion of the audio video communication session; and
