I. Video Playback 1) create a play_window_layer 2) The play_window_layer address buffer is used as the decoder output address, generally rgb565. (Yuv422 can also be directly output in the new version. You need to call gdi_layer_set_color_format (gdi_color_format_uyvy422) to set it to screen flushing by yuv422 .) 3) after each frame is decoded, call gdi_layer_blt_previous to fl the screen. Or you can use the write Register Method to screen more quickly. For more information, see start_ LCD _tr

is the callback function passed to L4StartTimer as a parameter. Because MTK is encapsulated, the internal callback trigger process is specific. I cannot know, but according to the speculation, it should be at the scheduled time, send the message in the form of interruption (MSG_ID_TIMER_EXPIRY), and write it to the MMI loop queue. This function may be called in L4CallBackTimer. The functions of L4CallBackTimer are as follows: A. Reset the currentTime
