The invention discloses an end-to-end video sending method and device. The method comprises the steps of determining a first bandwidth measurement value C(k)= [C-wave,...,C-wave-M]; predicting an available bandwidth prediction value C^caret of a next I frame interval (k+1) based on the first bandwidth measurement value; determining a rate limit value for sending video frames within the next I frame interval according to the available bandwidth prediction value and a preset trusted parameter; coding the video frames within the next I frame interval in a layered -P(hP) coding mode according to the rate limit value, thereby obtaining a coded video stream, and recording a coding rate and a time sequence layer priority of each coded frame within the next I frame interval; and sending the coded video stream according to the preset rule.
