Distribution and use of video statistics for cloud-based video encoding

摘要

A method for processing a video stream includes receiving first and second copies of the video stream by first and second video processing devices, respectively, and generating first and second statistical data for the video stream by the first and the second video processing devices, respectively. The method further includes transmitting in first and second transmissions the first and the second copies of the video stream with the first and the second statistical data respectively from the first and the second video processing device to a third video processing device, and reading the first and the second statistical data from the first and the second transmissions by the third video processing device. The method further includes combining the first and the second statistical data with one copy of the video stream by the third video processing device, and transmitting the one copy of the video stream with the first and the second statistical data.

1. A method for processing a video stream comprising:
receiving a first copy of the video stream and a second copy of the video stream by a first hardware encoder and a second hardware encoder, respectively; processing the first copy of the video stream and the second copy of the video stream to generate first statistical data and second statistical data for the video stream using the first hardware encoder and the second hardware encoder, respectively, wherein at least one of the first statistical data and the second statistical data includes information indicating content detected in the video stream; transmitting, in a first transmission by the first hardware encoder, the first copy of the video stream with the first statistical data; transmitting, in a second transmission by the second hardware encoder, the second statistical data; receiving the first copy of the video stream with the first statistical data from the first transmission by the first hardware encoder and the second statistical data from the second transmission by the second hardware encoder by a third hardware encoder; in response to receiving the first copy of the video stream with the first statistical data from the first hardware encoder and the second statistical data from the second hardware encoder, generating, using the third hardware encoder, third statistical data for the video stream using at least one of the first statistical data and the second statistical data; combining the first statistical data, the second statistical data, and the third statistical data with the first copy of the video stream to produce a third video stream, wherein the first statistical data, the second statistical data, and the third statistical data are included in one or more in-band portions of the third video stream; and transmitting the third video stream.
