and carrying out compression coding processing on each image frame according to the target resolution of each image frame to obtain the coded stream data of the target image.
5. The method according to claim 4, wherein said compression encoding each image frame according to the target resolution of said each image frame to obtain encoded stream data of said target image comprises:
determining a target coding parameter corresponding to the target resolution of each image frame according to the target resolution of each image frame;
and respectively carrying out compression coding processing on each image frame according to the target coding parameters of each image frame to obtain a coded data stream of the target image.
6. The method of claim 5, wherein the target encoding parameters comprise quantization parameters; the compressing and encoding process is performed on each image frame according to the target encoding parameters of each image frame, so as to obtain an encoded data stream of the target image, including:
respectively adjusting the size of each image frame according to the quantization parameter of each image frame;
and carrying out compression coding processing on each image frame after the size is adjusted to obtain a coded data stream of the target image.
7. The method of claim 5, wherein the encoding parameters comprise a quality scaling factor; the compressing and encoding process is performed on each image frame according to the target encoding parameters of each image frame, so as to obtain an encoded data stream of the target image, including:
respectively adjusting pixels of each image frame according to the quality scaling coefficient of each image frame;
and carrying out compression coding processing on each image frame after the pixel adjustment to obtain a coded data stream of the target image.
