Embodiment Construction
[0052] Such as figure 1 As shown, in the flow chart of Embodiment 1 of the method for embedding time in a video frame of a player in the present invention, the method for embedding time in a video frame performs the following steps after decoding the video frame:
[0053] S100. Extracting time data from the time stamp of the current video frame, it should be noted that the extracted time data is in text format;
[0054] S200. Rounding the extracted time data to seconds;
[0055] S300. Use the rounded time data as the current time data of the video, and store it in the first buffer;
[0056] S400. Convert the format of the current time data of the video according to the format of the video frame, and store the outputted time data in the corresponding picture format into the second buffer. The format of the video frame can be YV12, YUY2, RGB24, etc. In this step, since the current time data of the video before conversion is in text format, the current time data of the video af...

The invention discloses a player and a method for embedding time in video frames of the player. The method includes the steps of A, extracting time data from a timestamp of a current video frame; B, rounding the extracted time to second; C, saving the rounded time data into a first buffer; D, converting a format of current time data of the video according to the format of the video frame, and saving the output time data of the corresponding image format into a second buffer; and E, mixing the time data of the image format in the second buffer with the current video frame to output the video frame embedded with time. According to the technical scheme, the video frame embedded with time can be output, and the current time of the video can be displayed even in full-screen playing. Besides, when user carries out screenshot to the video of a certain time point or range, the corresponding time point is saved, and the screenshot pictures can be searched conveniently later according to the time point.
Description
technical field [0001] The invention relates to video processing technology, in particular to a method for embedding time in a video frame and a player. Background technique [0002] When the video is playing, most users want to display the current time, total playing time, remaining playing time and current system time of the video on the playing window, especially when users sometimes need to specify to watch the video content at a specific time period or time point in the video, The playback time displayed on the playback window is very helpful for video positioning. However, when the existing player is playing a video, the displayed playing time is realized in the form of a small window superimposition, and the time is not directly written in the video frame. In this case, when the user performs a screenshot operation, the intercepted The pictures are also saved at the time points in the entire video, so it is not convenient to search for the captured pictures according...
