Decoding method, encoding method, device, computer-readable storage medium and product
By introducing a feature propagation controller into the video coding model, which clears the cached features according to the refresh cycle and uses the reconstructed video frames for decoding or encoding, the quality degradation problem of the end-to-end video coding model in long video sequences is solved, achieving a balance between quality stability and efficiency.

AI Technical Summary
End-to-end video coding models suffer from a degradation in coding quality in long video sequences. Existing strategies, such as reducing the number of intra-frame codes or hierarchical quality structures, have limited effectiveness in long video sequences and sacrifice coding efficiency.
By introducing feature propagation controllers at the decoding and encoding ends, buffered features are cleared according to the refresh cycle, and only reconstructed video frames are used for decoding or encoding, ensuring precise timing alignment of the encoding and decoding processes and reducing error accumulation.
Without sacrificing the quality grading structure, it effectively eliminates error accumulation, ensures the stability of decoding quality for long video sequences, and improves video quality while maintaining encoding efficiency.
