mpv window freeze before video end - rfeyer - Feb-13-2021
Hi all,
mostly new to python, certainly new to tkinter and mpv!
wrote a little python/tkinter script to select recorded mkv's (from motion) which then play via mpv. All works OK, but:
whether I select one or multiple video's, one of two things are a problem:
1- if I pause any video before end and try to close the player window, it freezes until I close the app from idle
2- if I select one mor multiple mkv's, then either play to end or go through selection process again (via Browse button), the app closes.
Here is the complete code:
#!/usr/bin/python3
import os
import shutil
import tkinter as tk
from tkinter import *
from tkinter import ttk
from tkinter import filedialog
from tkinter import messagebox
import webbrowser
if os.environ.get('DISPLAY','') == "":
print('no display found.Using :0.0')
os.environ.__setitem__('DISPLAY',':0.0')

I think there's known issues with using tk inside idle. Does the same behavior exist when running your program normally, via the command line?

Ty vm for looking this over. I am kinda lost as I can't find anything online
Yup, the program reacts the same when being called from a bash or terminal.
RE: mpv window freeze before video end - rfeyer - Feb-16-2021
Not sure if I overwhelmed with entering the whole code.
It is worth noting, that, with all the Buttons and Defs (i.e.: View, Copy, Delete, Move), the View function is the only one causing problems of sudden program exit on second file selection attempt.
I can not find any examples explaining MPV player playing multiple videos in succession ( i.e.: utilizing the askopenfilenames multiple selection widget.
here is what I am currently using:
def ViewFile():
# plays all selected files one by one, keeps speed selected in 1st clip unless changed..
files_list = WidgetFrame.files_list
print(files_list)
# loop through files
for f in files_list:
player.play(f)
player.playlist_append(f)
player.wait_for_playback()
player.wait_for_playback
Would it be better to try and write the askopenfilenames resulting tuble to a playlist file and use that with MPV?
RE: mpv window freeze before video end - rfeyer - Feb-16-2021
OK,so I have tried dozens of different avenues to loop through a tuple, no success.
I have been able to write the tuple files to a file called mplaylist.e3u
However, now I can not find any coding or explanation which shows how to play a playlist from within python.
What I have now is:
import mpv
player = mpv.MPV(ytdl=True,input_default_bindings=True,input_vo_keyboard=True,osc=True)
def ViewFile():
files_list = WidgetFrame.files_list
# loop through files
with open( 'mPlaylist.u3e', 'w+' ) as playlist:
for f in files_list:
print(f)
playlist.write( f + '\n' )
player.play("mPlylist.u3e")
player.wait_for_playback
playlist.close()ANY suggestions would be greatly appreciated
RE: mpv window freeze before video end - Axel_Erfurt - Feb-16-2021
This works for me
import mpv
player = mpv.MPV(ytdl=True,input_default_bindings=True,input_vo_keyboard=True,osc=True)
media = open('playlist.m3u', 'r').read().splitlines()
try:
for item in media:
player.play(item)
player.wait_for_playback()
except mpv.ShutdownError:
pass
RE: mpv window freeze before video end - rfeyer - Feb-17-2021
TY - that works! But only when I use it as a standalone.
When I plug it into the function of the (initially posted) script, one of two things happen:
1- if I halt the strem (rightclick) and try to close the window the stream is playing in, the window freezes and I have to close the program from IDLE (or a quit button I have in it).
2- If I let the video/s run through to end, the window closes. But, if I try to select more files via Browse button (activating askopenfilenames()) then the program closes down abruptly as soon as the new file selections are made.
Essentially, this happens with your code and with mine.
I haven't a clue what to try next!
I made a shorter version of the program (removed the other labes/buttons/functions) to it's easier on the eye to look through:

My apology - I thought I had the python /python with [] included before and after text, but it is not showing correctly and the edit button won't let me edit
RE: mpv window freeze before video end - Axel_Erfurt - Feb-17-2021
Do you have to use tkinter? There are better and easier ways for video.
RE: mpv window freeze before video end - rfeyer - Feb-17-2021
no, I don't have to use tkinter.
I simply chose it as it works with python, which I had used some about 12 years ago.
My needs are to view mkv video files (usually 15 to 120 seconds each) which are produced by motion video surveillance program.
I have motion configured to store each cameras files in separate folders. However, it can produce an easy 50 each per day. I would also like it to show live streaming feeds of the cameras, all on one page and separately full screen.
I also need to view the files over LAN, and 2-3 times per year over web.
I could easily ssh, but my wife is not into ssh or even folders.
12 years ago I made a program to automate our chicken coop (doors/lights/water heaters,etc using python and Flask on RPI's. I did start something for the cameras with Flask, but when running into hurdles could not get any help response from forums, so had to give up. Been working on this for a couple of months now.
What suggestions would you have? I am retired and willing to learn something new as long as my 63 yo brain can comprehend it.
