Abstract
An adaptive video encoding method includes: encoding, by an encoding circuit, a current frame to generate a current encoded frame; and after the current frame is encoded, obtaining quantization parameter information of at least one encoded frame, wherein the at least one encoded frame includes the current encoded frame, and referring to the quantization parameter information to adaptively adjust a frame rate of at least one next frame to be actually encoded by the encoding circuit.
Claims22
An adaptive video encoding method comprising:
- encoding, by an encoding circuit, a current frame to generate a current encoded frame;
- and
- after the current frame is encoded:
- obtaining quantization parameter information of at least one encoded frame, wherein said at least one encoded frame comprises the current encoded frame;
- and
- referring to the quantization parameter information to adaptively adjust a frame rate of at least one next frame to be actually encoded by the encoding circuit.
An adaptive video encoding method comprising:
- encoding, by an encoding circuit, a current frame to generate a current encoded frame;
- and
- after the current frame is encoded:
- setting re-encode indication according to at least encoding-related information of the current frame;
- and
- referring to the re-encode indication for adaptively re-encoding, by the encoding circuit, the current frame to update the current encoded frame.
A video encoder for adaptive video encoding, comprising:
- an encoding circuit, arranged to encode a current frame to generate a current encoded frame;
- and
- a control circuit, wherein after the current frame is encoded, the control circuit is arranged to:
- obtain quantization parameter information of at least one encoded frame, wherein said at least one encoded frame comprises the current encoded frame;
- and
- refer to the quantization parameter information to adaptively adjust a frame rate of at least one next frame to be actually encoded by the encoding circuit.
A video encoder for adaptive video encoding, comprising:
- an encoding circuit, arranged to encode a current frame to generate a current encoded frame;
- and
- a control circuit;
- wherein after the current frame is encoded, the control circuit is arranged to set re-encode indication according to at least encoding-related information of the current frame, and the encoding circuit is further arranged to refer to the re-encode indication for adaptively re-encoding the current frame to update the current encoded frame.
