Video playback Raspbian Buster (Full) Raspberry PI4 2gb and 4gb

[Lee Goodman]

Hi guys very new to PYGLET and python, trying to piece together a script which is coming on very well other than video playback.

This is the sample code i have used

import pyglet

import youtube_dl

from pyglet.gl import *

glScalef(0.5, 0.5, 0.5)

#youtube play test===========================

#Youtube video download======================

streampath = "https://www.youtube.com/watch?v=LD_WvcLi95I"

output='spiderbath.mpg'

ydl_opts = {'outtmpl':output,'format':'134'}

#youtube_dl.YoutubeDL()

with youtube_dl.YoutubeDL(ydl_opts) as ydl:

   ydl.download([streampath])

#video playback=============================

MediaLoad = pyglet.media.load(output) 

player = pyglet.media.Player()

source = pyglet.media.StreamingSource()

window= pyglet.window.Window(1800,900)

player.queue(MediaLoad)

player.play()

print (player.source.video_format)

face_image = pyglet.image.load('clouda.png')

face = pyglet.sprite.Sprite(face_image, x=50, y=650)

animation = pyglet.image.load_animation('example-2.gif')

animSprite = pyglet.sprite.Sprite(animation)

w = animSprite.width

h = animSprite.height

 

@window.event

def on_draw():

    window.clear()

    if player.source and player.source.video_format:

        player.get_texture().blit(350,100)

    #animSprite.draw()

    face.draw()

@window.event

def on_close():

    print("close")

    player.pause()

    window.close()

@player.event   

def on_player_eos():

    print('end')

    window.close()

pyglet.app.run()

Ignore the sprites its the video playback that is having issues, im getting the following in the shell window before it dumps me out.

I have installed Gstreamer v1.0 because I had issues with the media player not working at all but it at least plays sound now.

I assume (or hope) there is a package I havent installed, The script works on my pc as it should but as soon as I try the same script on either raspberry pi 4 (2gb and 4gb) I get the above error reports.

I would appreciate any help , this is a tiny part of a large script ive been writing over the last week, its for a project for my granddaughter.

The mistake I made was to write and test on my pc and not try on the pi before I prceeded any further DOH!.

Many thanks
