Abstract
A method for searching for a flash video (FLV) tag in a bitstream includes the following steps: setting a first start position and a first search length related to a first search process, wherein the first search length indicates a bitstream length of the first search process performed upon the bitstream; starting the first search process upon the bitstream from the first start position to search for the FLV tag; when the FLV tag is not found in the first search length, setting a second start position related to a second search process immediately following the first search process, wherein the first start position and the second start position are separated by a time period equaling a sum of the first search length and a first skip length corresponding to the first search process; and starting the second search process upon the bitstream from the second start position to search for the FLV tag.
