1. A method of processing videos, comprising:
obtaining a video to be transcoded, the video comprising a plurality of frames;
embedding a test object in each of the plurality of frames of the video to be transcoded, wherein the test object in each of the plurality of frames of the video to be transcoded comprises a video parameter, and wherein the test object is configured to test a transcoding result;
transcoding the video using a predetermined video transcoding mechanism and obtaining the transcoded video;
extracting the test object from each of a plurality of frames of the transcoded video; and
determining an accuracy of the transcoding result based on a first sequence of video parameter comprised in the test object embedded in each of the plurality of frames of the video to be transcoded and a second sequence of video parameter comprised in the test object extracted from each of the plurality of frames of the transcoded video.
