A coding parameter determining method, apparatus, and computer-readable storage medium for efficient video recoding. The method parses a bit stream to obtain a coded picture and decoding information, then decodes the coded picture using the decoding information to produce a reconstructed picture. Based on decoding parameters contained in the decoding information, coding parameters are determined for recoding the reconstructed picture. The reconstructed picture is then recoded using these determined coding parameters to generate a recoded bit stream. This approach enables intelligent recoding by leveraging decoding parameters from the original encoding process to inform recoding decisions, facilitating efficient video transcoding and format conversion operations.
