Abstract: Provided in the embodiments of the present disclosure are a multimedia resource processing method and apparatus, and an electronic device and a readable storage medium. On the basis of a contribution feature, the number of future visits of a multimedia resource uploaded by a contribution user can be predicted; a transcoding priority is obtained on the basis of the number of future visits of the multimedia resource; and the multimedia resource with a high transcoding priority is preferentially transcoded.

Abstract: Embodiments of the present disclosure provide an adaptive playback method and device for video, the method includes: receiving a playback instruction for a target video; and playing the target video according to a first code rate in response to the playback instruction; where the first code rate is determined by the following steps: predicting by using a network speed prediction algorithm to obtain a first network speed; acquiring a code rate prediction model corresponding to the network speed prediction algorithm, where the code rate prediction model is used for representing, under a historical performance parameter before switching to the network speed prediction algorithm, a mapping relationship between a network speed predicted by the network speed prediction algorithm and a code rate; and determining the first code rate corresponding to the first network speed through the code rate prediction model.
