Adaptive batch encoding for slow motion video recording

A system for adaptively batching encode tasks for slow motion video recording comprising:

• a memory comprising a buffer for storing video frames;
• a camera to:
• capture, in a slow motion video record mode, first video at a first frame rate of not less than twice a second frame rate of a standard video record mode;
• and
• capturing, in the standard video record mode, second video at the second frame rate;
• a central processor coupled to the memory, the central processor to:
• store to the buffer, in response to the first video being captured in the slow motion video record mode, a plurality of first video frames of the first video to generate an encode batch comprising the plurality of first video frames;
• and
• store to the buffer, in response to the second video being captured in the standard motion video record mode, a plurality of second video frames of the second video;
• and a graphics processor to:
• encode, during a continuous active state of the graphics processor, the encode batch to generate an encoded bitstream, wherein the graphics processor does not enter a low power state during the continuous active state;
• and
• encode the second video frames to generate a second encoded bitstream, wherein the graphics processor enters the low power state between encode of each of the second video frames.

At least one non-transitory machine readable medium comprising a plurality of instructions that, in response to being executed on a computing device, cause the computing device to adaptively batch encode tasks for slow motion video recording by:

• capturing, in a slow motion video recording mode, first video at a first frame rate of not less than twice a second frame rate of a standard video recording mode;
• buffering, in response to the first video being captured in the slow motion video recording mode at the first frame rate, a plurality of first video frames of the first video to generate an encode batch comprising the plurality of first video frames;
• submitting the encode batch comprising the plurality of first video frames for encoding to a graphics processor;
• encoding, during a continuous active state of the graphics processor, the encode batch to generate a first encoded bitstream, wherein the graphics processor does not enter a low power state during the continuous active state;
• capturing, in the standard video recording mode, second video at the second frame rate;
• buffering, in response to the second video being captured in the standard video recording mode at the second frame rate, a plurality of second video frames of the second video;
• submitting the second video frames for encoding to the graphics processor;
• and
• encoding, via the graphics processor, the second video frames to generate a second encoded bitstream, wherein the graphics processor enters the low power state between encode of each of the second video frames.
