Abstract: A vehicle decision-making planning method, apparatus, device, and medium comprises generating a base coordinate system, generating a guide line in the base coordinate system to determine an approximate travel trajectory of a vehicle in the future, performing obstacle decision-making under the constraint of the guide line, and generating a drivable area based on the obstacle decision-making.

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.
