I didn’t find an easy and working movie player for wide screen setups. Like double/triple monitor setups.
I’ve got 3x 1920×1080 monitors connected to my battlestation. With a resolution of 5760×1080
Simple Python code to play a movie fullscreen
# importing vlc module
import vlc
# creating vlc media player object
media_player = vlc.MediaPlayer()
# media object
media = vlc.Media("movie.mp4")
# setting media to the media player
media_player.set_media(media)
media_player.toggle_fullscreen()
# start playing video
media_player.play()
But trying to get this stable working, I resorted to pysimplegui
#!/usr/bin/env python3
import PySimpleGUI as sg
import vlc
import sys
from sys import platform as PLATFORM
try:
movie=sys.argv[1]
except:
print(sys.argv[0] + " filename")
exit()
sg.theme('DarkBlue')
layout = [[sg.Image('', size=(5760, 1080), key='-VID_OUT-')]]
window = sg.Window('Triple movie player', layout, no_titlebar=True, margins=(0,0),location=(0,0), size=(5760,1080), keep_on_top=True, finalize=True,resizable=False)
window.bring_to_front()
window.Maximize()
window.bind("<Escape>", "-ESCAPE-")
window.bind("<Return>", "-ENTER-")
window['-VID_OUT-'].expand(True, True)
inst = vlc.Instance()
list_player = inst.media_list_player_new()
media_list = inst.media_list_new([])
list_player.set_media_list(media_list)
player = list_player.get_media_player()
if PLATFORM.startswith('linux'):
player.set_xwindow(window['-VID_OUT-'].Widget.winfo_id())
else:
player.set_hwnd(window['-VID_OUT-'].Widget.winfo_id())
media_list.add_media(movie)
list_player.set_media_list(media_list)
list_player.play()
while True:
event, values = window.read(timeout=1000)
if event == sg.WIN_CLOSED:
break
if event == '-ENTER-':
list_player.play()
if event == '-ESCAPE-':
list_player.stop()
window.close()
window.close()
I’ve converted some of my Vuze media to the correct resolution using kdenlive.
Created this for usage with Kodi, for our own personal movies, which can’t be scraped by movie scrapers obviously. (dvd-rip,digital video, mobile movies, OBS, Vuze and Nikon movies for example)
UPDATE V2 added functions
This is a followup on:
Works on Windows also!
Needed libraries: (install with pip) pathlib, Pillow, pymediainfo,PySimpleGUI,python-vlc
NFO created
Title – editable (generated from filename) Duration – mediainfo data in seconds Plot – Single line type it yourself Actors – Predefined Tags – Predefined checkboxes Country – Pulldown ( I use this as location, Scotland, Asia, Garden) Year – default 2023, copy button from mobile phone metadata year Genre – Pulldown
Works
File select and loaded
Play movie, scrub thretro movie
Create snapshot
Play/Mute/Pause
Playtimer
Auto update NFO text field with selectable options
Poster art – rotate
Poster art – brightness
Reload Thumb after snapshotting
Year extracted from filename
add tag field
Next file (button AND functionality)
checkboxes from text list
Read NFO from file into fields
Poster art – aspect ratio
Needs work
Wish list
Poster art – contrast?
Low – more mediainfo?
Low – Media rotate??
The GUI in action (V1)
Kodi example
CODE ( WIP ) V2 I place this python script in every library directory. So i can change the checkboxes and the NFO being generated. I fill the directory with symlinks for every movie I want to have included in this directory, but this is not needed. (thats the way I like to do things) (This is the directory I scrape into Kodi)

Today I was working on my own brew ISA card (wirewrapping). Did some mini modeling stuff. Sorted some pipetunes. And played around with my 8086.
Got it on a desk now, and replaced the harddisk with the CF card. Also got an old SoundBlaster working, so i wanted to see what of my old code could still run. Apparanty most code was compiled for 386/486 🙁 So i recompiled some stuff. Below a horizontal scroller example.
Meanwhile i got my new fans in for my NUC (Kodi player, it was making a hell of a noise due to bad ball bearings.
Got some new roms in. These are for my 8088/8086 the 6502 computer and C64 cartridges.
While I seldom had any problem writing to these, now I could not write one! Erasing didn´t give me an error?!?

I found some parts of our (Edk and Me) bootloader demo.
It was compiled using masm or tasm. Encountering a problem converting the code into a raw bin, to put on a floppy I diverted to another setup to try to get things working.
Using old code (below) and a example from YT, I made the following setup.
Visual studio code, with the x64 assembly plugin. xxd as hexviewer. fasm as assembler (This makes things easier, because it is a native Linux x86 compiler. So no need for dosbox anymore.)

Booting the demo in milli seconds using qemu. Next to do: Write this to floppy and test on real hardware.
A reset starts the virtual machine and boots from a virtual floppy. The drawing of the pixels is slow, because I used a int 10h function for every pixel, instead of writing to screen memory directly.
Got a part working again in PCem. This is from our bootdemo. A scroller and sector loader in a bootsector. Needed some include files masm, link, exe2com creates a 12- sector sized floppy. And we’ve got a (little distorted but working) Scroller in boot sector with custom font!
font: db 64 dup (0) ;space

Today two boot projects. One using a bios extension, so it chip based. Second is a floppy disk boot program. (Creating a test situation to get our old Boot floppy demo working. ( That one without using an operatingsystem like ms-dos.
