Distributing compressed video frames in a video conference
One disclosed example method includes receiving, by a video conference provider, video frames from a plurality of existing participants in a video conference; receiving, by the video conference provider, a request from a new user to join the video conference, and in response: generating, by the video conference provider, an instantaneous decoder refresh (IDR) frame; determining, by the video conference provider, one or more prior video frames previously acknowledged by each existing participant of the plurality of existing participants; generating, by the video conference provider, a benchmark frame for each of the plurality of existing participants based on at least one of the determined one or more prior video frames and the IDR frame; transmitting, by the video conference provider, the IDR frame to the new user; and transmitting, by the video conference provider, a message comprising the benchmark frame to each of the plurality of existing participants.
1. A method comprising:
receiving, during a video conference hosted by a video conferences provider, video streams from a subset of participants of a plurality of participants of the video conference,
receiving, for each video stream from the subset of the participants, a benchmark video frame;
generating, for each received benchmark video frame, a new full video frame; and
establishing a new instantaneous decoder refresh (“IDR”) video frame for each new full video frame.
2. The method of claim 1 , further comprising receiving instructions to establish the new IDR video frame.
3. The method of claim 1 , wherein the benchmark video frame comprises video information indicating differences between one or more acknowledged differential video frames and a prior IDR video frame.
4. The method of claim 1 , wherein generating the new full video frame is based on locally-stored data and the benchmark video frame.
5. The method of claim 1 , wherein the benchmark video frame is encoded in an IDR format.
6. The method of claim 1 , wherein the benchmark video frame is configured to be synthesized locally as a P-frame.
7. The method of claim 1 , wherein receiving the video streams comprising receiving one or more differential video frames, each differential video frame based on a prior IDR video frame and zero or more intervening differential video frames.
8. A system comprising:
a non-transitory computer-readable medium; and
a processor in communication with the non-transitory computer-readable medium, the processor configured to execute processor-executable instructions stored in the non-transitory computer-readable medium to:
receive, during a video conference hosted by a video conferences provider, video streams from a subset of participants of a plurality of participants of the video conference,
receive, for each video stream from the subset of the participants, a benchmark video frame;
generate, for each received benchmark video frame, a new full video frame; and
establish a new instantaneous decoder refresh (“IDR”) video frame for each new full video frame.
9. The system of claim 8 , wherein the processor is configured to execute further processor-executable instructions stored in the non-transitory computer-readable medium to receive instructions to establish the new IDR video frame.
10. The system of claim 8 , wherein the benchmark video frame comprises video information indicating differences between one or more acknowledged differential video frames and a prior IDR video frame.
11. The system of claim 8 , wherein generating the new full video frame is based on locally-stored data and the benchmark video frame.
12. The system of claim 8 , wherein the benchmark video frame is encoded in an IDR format.
13. The system of claim 8 , wherein the benchmark video frame is configured to be synthesized locally as a P-frame.
14. The system of claim 8 , wherein the processor is configured to execute further processor-executable instructions stored in the non-transitory computer-readable medium to receive instructions to receive one or more differential video frames, each differential video frame based on a prior IDR video frame and zero or more intervening differential video frames.
15. A non-transitory computer-readable medium comprising processor-executable instructions configured to cause a processor to:
receive, during a video conference hosted by a video conferences provider, video streams from a subset of participants of a plurality of participants of the video conference,
receive, for each video stream from the subset of the participants, a benchmark video frame;
generate, for each received benchmark video frame, a new full video frame; and
establish a new instantaneous decoder refresh (“IDR”) video frame for each new full video frame.
16. The non-transitory computer-readable medium of claim 15 , further comprising processor-executable instructions configured to cause a processor to establish the new IDR video frame.
17. The non-transitory computer-readable medium of claim 15 , wherein the benchmark video frame comprises video information indicating differences between one or more acknowledged differential video frames and a prior IDR video frame.
18. The non-transitory computer-readable medium of claim 15 , wherein the benchmark video frame is encoded in an IDR format.
19. The non-transitory computer-readable medium of claim 15 , wherein the benchmark video frame is configured to be synthesized locally as a P-frame.
20. The non-transitory computer-readable medium of claim 15 , further comprising processor-executable instructions configured to cause a processor to receive instructions to receive one or more differential video frames, each differential video frame based on a prior IDR video frame and zero or more intervening differential video frames.
