i'm using to embed the ffplay window into my tkinter frame.
that's my code:
file = "path/to/the/file.mp4"
command = subprocess.Popen(["ffplay","-i","%s"%file],stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, text=True,)
pid = gw.getWindowsWithTitle('%s'%file) #getting the hwnd of the ffplay window
hwnd = re.findall(r'\d+',str(pid))
x = int(videoWidget.winfo_x()) #video widget is the target tkinter frame
y =int(videoWidget.winfo_y())
width = int(videoWidget.winfo_width())
height = int(videoWidget.winfo_height())
win32gui.MoveWindow(int(hwnd[-1]), int(x), int(y),int(width) , int(height), 1) # trying to move the ffplay window to the videowidget geometry
win32gui.SetParent(int(hwnd[-1]),int(stream_id)) #trying to set the parent of the ffplay window to the videowidget, that should show the ffplay window in the tkinter frame
the code run without any error, but the both ffplay window and tkinter window stop responding without any error
if any one can help me in this i'll be thankful
Root cause of stopping responding:
stdout=PIPE and/or stderr=PIPE.
It blocks the output of ffmpeg and cause a deadlock.
You could create a new console for the output of the ffmpeg.
My test sample:
import subprocess
from subprocess import Popen, CREATE_NEW_CONSOLE
import pygetwindow as gw
import win32gui
import regex as re
import time
file = "path/to/the/file.mp4"
proc = subprocess.Popen(["ffplay","-i","%s"%file], creationflags = CREATE_NEW_CONSOLE)
time.sleep(2) #make sure the window has been started and available to find.
pid = gw.getWindowsWithTitle('%s'%file) #getting the hwnd of the ffplay window
hwnd = re.findall(r'\d+',str(pid))
print(hwnd)
x = 0 #video widget is the target tkinter frame
y = 0
width = 800
height = 500
win32gui.MoveWindow(int(hwnd[-1]), int(x), int(y),int(width) , int(height), 1) # trying to move the ffplay window to the videowidget geometry
In addition, you should make sure you have started the window before calling getWindowsWithTitle.
