Windows10下Pyglet播放视频仅出声无画面问题求助

Hey there, let's get your Pyglet video playback showing actual frames instead of just sound. I've gone through your code and spotted a few key issues, plus some extra tips to make it work smoothly:

Key Problems in Your Code #

• Typos break rendering: You wrote player.get_texture().bilt(50,50) — that's a typo! The correct method name is blit (missing an 'l'). This is why the video frame never gets drawn.
• Unbound draw event: You defined an on_draw function, but never told Pyglet's window to use it. Without binding this function to the window's on_draw event, Pyglet has no idea it needs to run your rendering logic.
• No screen clearing: Before drawing the video texture, you need to clear the window first. Skipping this can cause visual glitches or prevent the texture from showing up at all.

Corrected Code #

Here's the fixed version with explanations in comments:

import pyglet

vidPath = 'cc.avi'
window = pyglet.window.Window(fullscreen=True)
player = pyglet.media.Player()

# Load your video file
media_source = pyglet.media.load(vidPath)
player.queue(media_source)
player.play()

# Critical: Bind this function to the window's draw event
@window.event
def on_draw():
    window.clear()  # Clear the window before rendering
    if player.source and player.source.video_format:
        texture = player.get_texture()
        # Option 1: Stretch video to fill the fullscreen window
        texture.blit(0, 0, width=window.width, height=window.height)
        # Option 2: Keep fixed position (like your original code)
        # texture.blit(50, 50)

pyglet.app.run()

Extra Troubleshooting Tips #

If you still don't see video after fixing the code:

• Install FFmpeg support: Pyglet relies on FFmpeg to decode most video formats. Reinstall Pyglet with FFmpeg bindings using:

  pip install pyglet[ffmpeg]
  

• Check video encoding: Some AVI/MP4 files use rare or unsupported codecs. Try converting your video to a standard H.264-encoded MP4 and test again — this is the most widely supported format for Pyglet.
