Abstract
Still frame detection for single pass video data, including: determining that an average quantization parameter of a frame of video data falls below a quantization parameter threshold; determining whether an amount of skipped macroblocks in the frame meets a skipped macroblock threshold; and responsive to the amount of skipped macroblocks exceeding the skipped macroblock threshold, identifying the frame as a still frame.
Claims20
A method of still frame detection in video data, the method comprising:
- determining that an average quantization parameter of a frame of video data falls below a quantization parameter threshold;
- determining, in response to the average quantization parameter falling below the quantization parameter threshold, whether an amount of skipped macroblocks in the frame meets a skipped macroblock threshold;
- and
- responsive to the amount of skipped macroblocks exceeding the skipped macroblock threshold, identifying the frame as a still frame.
An apparatus for still frame detection in video data, the apparatus comprising:
- a processor;
- and
- memory, the memory including instructions that, when executed by the processor, cause the apparatus to:
- determine that an average quantization parameter of a frame of video data falls below a quantization parameter threshold;
- determine, in response to the average quantization parameter falling below the quantization parameter threshold, whether an amount of skipped macroblocks in the frame meets a skipped macroblock threshold;
- and
- responsive to the amount of skipped macroblocks exceeding the skipped macroblock threshold, identify the frame as a still frame.
A computer program product disposed upon a non-transitory computer readable medium, the computer program product comprising computer program instructions for still frame detection in video data that, when executed, cause a computer system to perform steps comprising:
- determining that an average quantization parameter of a frame of video data falls below a quantization parameter threshold;
- determining, in response to the average quantization parameter falling below the quantization parameter threshold, whether an amount of skipped macroblocks in the frame meets a skipped macroblock threshold;
- and
- responsive to the amount of skipped macroblocks exceeding the skipped macroblock threshold, identifying the frame as a still frame.
