Abstract

A method and a computer product for processing video streams. The computer product is a virtual camera configured to: obtain a sequence of video frames from the video source; generate a sequence of alternative frames; the virtual camera computer product is implemented using program instructions that are executable by a processor, the virtual camera computer product comprises: an areas determination module, said area determination module is configured to: obtain a first frame from the video source; determine a first interesting area comprised by the first video frame displaying an image of an object, whereby determining a first non-interesting area, wherein the first non-interesting area is a complement, in the first video frame, of the interesting area; a first processing channel configured to: process the first video frame based on the first interesting area, whereby determining a first interesting alternative frame; write the first interesting alternative video frame to a shared memory location; a second processing configured to: process the first video frame based on a non-interesting area, whereby determining a first non-interesting alternative frame; write the first non-interesting alternative video frame to the shared memory location, whereby generating the first alternative frame of the alternative video stream, wherein the video stream, when encoded, is associated with a first footprint, wherein the alternative video stream, when encoded, is associated with a second footprint, wherein the second footprint is smaller than the first footprint, wherein a video software is configured to obtain the alternative video stream frame by frame.

Dependent claims

A virtual camera computer product retained a non-transitory computer readable medium, wherein the virtual camera is configured to:

obtain a sequence of video frames from the video source, whereby obtaining a video stream frame by frame;
generate a sequence of alternative frames, whereby generating an alternative video stream;
the virtual camera computer product is implemented using program instructions that are executable by a processor, the virtual camera computer product comprises:
an areas determination module, said area determination module is configured to:
obtain a first frame from the video source, wherein the first frame comprised by the sequence of video frames;
determine a first interesting area comprised by the first video frame, wherein the first interesting area is displaying an image of an object, whereby determining a first non-interesting area, wherein the first non-interesting area is a complement, in the first video frame, of the interesting area;
a first processing channel configured to:
process the first video frame based on the first interesting area, whereby determining a first interesting alternative frame;
write the first interesting alternative video frame to a shared memory location;
a second processing configured to:
process the first video frame based on a non-interesting area, whereby determining a first non-interesting alternative frame;
write the first non-interesting alternative video frame to the shared memory location, whereby generating the first alternative frame of the alternative video stream, wherein the video stream, when encoded, is associated with a first footprint, wherein the alternative video stream, when encoded, is associated with a second footprint, wherein the second footprint is smaller than the first footprint, wherein a video software is configured to obtain the alternative video stream frame by frame.

A method comprising:

obtaining, by a virtual camera implemented in a computerized device, a first video frame, wherein the first video frame is comprised by a sequences of video frames;
determining a first interesting area comprised by the first video frame, wherein the first video frame comprised by the sequences of video frames, wherein the first interesting area is displaying an object, whereby determining a first non-interesting area;
processing the first video frame based on the first interesting area in a first processing channel, whereby determining a first interesting alternative video frame;
writing the first interesting alternative video frame to a shared memory location;
processing the first video frame based on the first non-interesting area in a second processing channel, whereby determining a first non-interesting alternative video frame;
writing the first non-interesting alternative video frame a shared memory location, wherein a video software is configured to utilize the first alternative video frame, wherein utilizing the first alternative video frame comprises encoding the first alternative video frame;
obtaining a second video frame from the video source, wherein the second video frame appears after first video frame in the sequence of video frames;
determining a second interesting area comprised by the second video frame, wherein the second interesting area is displaying the object;
processing the second video frame based on the second interesting area in the first processing channel, whereby determining a second interesting alternative video frame;
and
writing the second interesting alternative video frame to the shared memory location, whereby the shared memory location comprises a second alternative video frame, wherein the second alternative video frame comprises the second interesting alternative video frame and the first non-interesting alternative video frame, wherein the video software is configured to utilize the second alternative video frame, wherein utilizing the second alternative video frame comprises encoding the second alternative video frame, wherein a video stream comprising the first and second video frames, when encoded, is associated with a first footprint, wherein an alternative video stream comprising the first and second alternative video frames, when encoded, is associated with a second foot print, wherein the second footprint is smaller than the first footprint.
