videoplayer: Use code to control playback progress, play and pause

[EvenYeah]

using class videoplayer, how to control playback progress, play and pause by coding

[anrayliu]

When you create a VideoPlayer and pass it a Video object, you can save the Video object and use it directly manipulate the VideoPlayer. For example, to pause the video, just use video.pause() as normal.

thanks！and there's another problem. to display two windows simultaneously, I used two threads and played the video in one thread,and when i tried to use method video.seek(time=1) in the main thread, it showed 'Assertion fctx->async_lock failed at libavcodec/pthread_frame.c:173', i tried the mutex way, but it didn't work out

plus video.toggle_pause( ) worked fine,

You don't have to use threading to play videos in parallel. Here is the code from many_videos_demo.py found in the examples folder.

import pygame
from pyvidplayer2 import Video, VideoPlayer

win = pygame.display.set_mode((1066, 744))
pygame.display.set_caption("many videos demo")

videos = [VideoPlayer(Video(r"resources\billiejean.mp4"), (0, 0, 426, 240),  interactable=False),
          VideoPlayer(Video(r"resources\trailer1.mp4"), (426, 0, 256, 144), interactable=False),
          VideoPlayer(Video(r"resources\medic.mov"), (682, 0, 256, 144), interactable=False),
          VideoPlayer(Video(r"resources\trailer2.mp4"), (426, 144, 640, 360), interactable=False),
          VideoPlayer(Video(r"resources\clip.mp4"), (0, 240, 256, 144), interactable=False),
          VideoPlayer(Video(r"resources\birds.avi"), (0, 384, 426, 240), interactable=False),
          VideoPlayer(Video(r"resources\ocean.mkv"), (426, 504, 426, 240), interactable=False)]

while True:
    key = None
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            [video.close() for video in videos]
            pygame.quit()
            exit()
        elif event.type == pygame.KEYDOWN:
            key = pygame.key.name(event.key)

    pygame.time.wait(16)

    win.fill("white")

    [video.update() for video in videos]
    [video.draw(win) for video in videos]

    pygame.display.update()

As you can see, as long as every video is updated each frame, they will all play seperately.
