Accelerated re-encoding of video for video delivery
In one embodiment, the method determines a second location associated with a client device that requested to view an encoded video. Replacement content to insert in the encoded video to replace existing content is selected based on the location of the client device. The method decodes blocks in a frame of the encoded video in which the replacement content will be inserted and analyzes the decoded blocks to determine first blocks of the encoded video that will be affected by insertion of the replacement content and second blocks that will not be affected by the insertion. Motion prediction information is saved for the second blocks. The method then encodes the frame where the replacement content is inserted to replace the existing content. Motion prediction information for the second blocks is reused when performing the encoding of the second blocks.
