重现步骤

（一）：

from media.player import *
import os
import time
start_play = False
def player_event(event, data):
    global start_play
    print(f"Event: {event}, Data: {data}")  # 打印 event 和 data
    if event == K_PLAYER_EVENT_EOF:
        start_play = False
def play_mp4_test(filename):
    global start_play
    player = Player(Display.LT9611)
    player.load(filename)
    player.set_event_callback(player_event)
    player.start()
    start_play = True
    while start_play:
        time.sleep(0.1)
    player.stop()
    print("播放结束")
play_mp4_test("/sdcard/test/test.mp4")
play_mp4_test("/sdcard/test/test.mp4")

（二）：

from media.player import *
import os
import time
start_play = False
def player_event(event, data):
    global start_play
    if event == K_PLAYER_EVENT_EOF:
        start_play = False
def play_mp4_test(filename):
    global start_play
    time_old = time.time()
    player = Player(Display.LT9611)
    player.load(filename)
    player.set_event_callback(player_event)
    player.start()
    start_play = True
    while start_play:
        time.sleep(0.1)
        time_new = time.time()
        if time_new - time_old >= 15:
            player_event(event=0,data=0)
            print("播放结束")
    player.stop()
    time.sleep(0.1)
play_mp4_test("/sdcard/test/test.mp4")
play_mp4_test("/sdcard/test/test.mp4")
