@PaulleDemon TkvideoPlayer works fine with normal video but when a damaged file or non-video file is loaded then the pyav crashes and tkvideoplayer options also freezes and we have to restart the program.

Is there any way to reload or stop the pyav process in that case?

Secondly, I am also facing a playback speed issue with some raw videos (with variable frame rates) , I tried changing vid_player.set_resampling_method(1) and consistant_frame_rate=True but still the playback speed is very high with those videos.

How can I fix this?

First of all, thank you for your amazing work.

I have tried to use this library for playing several AVI videos. The videos in question are about 10-30 seconds long, with a resolution of 640x480 pixels at 120 FPS. Therefore, I noticed that the original videos play back slower than they should, about four times slower (I took the time with a stopwatch).

I saw that many other users experienced similar problems, so I tried the tkvideoplayer==2.3 version, but it doesn't seem to work.

Another thing I tried was downsampling the videos to 60 and 30 FPS, and as a result the playback seems to speed up 2 and 4 times respectively.

Maybe 120 frames are too many to be processed in real time?

Any ideas? What should I do?

Thank you.

I tested with master/examples/sample_player.py, and I am not sure what the problem is. Something about threads?

Thanks for creating this library, it helped me. But when i use <<Loaded>> event in example below, then the metadata is not printed. But your example with loop and <<Ended>> event - working good. I dont know why.

import tkinter as tk
from tkVideoPlayer import TkinterVideo
root = tk.Tk()
tkvideo = TkinterVideo(scaled=False, master=root)

#>>> both variants doesnt work
def showInf():
    print(tkvideo.metadata())
tkvideo.bind("<<Loaded>>", showInf) # prints the meta information
tkvideo.bind("<<Loaded>>", lambda e: print(tkvideo.video_info()), add='+') # prints duration frame rate and frame size
#<<<

tkvideo.load(r"video.mp4")
tkvideo.pack(expand=True, fill="both")
tkvideo.set_size((1200, 600)) # sets the frame size
tkvideo.play() # play the video

#>>> this variant works, when i click
def showMeta():
    print(tkvideo.metadata())
    print(tkvideo.video_info())
b = tk.Button(text="click me", command=showMeta)
b.pack()
#<<<

root.mainloop()

I am a little bit confused on the seek method, when I seek to a part while the video is paused then it doesn't display the frame, means it only displays the seeked part when it is played. I tried this method after seek while pausing the video and it worked but we have to use the time module and I think its not accurate;

vid_player.seek(int(5)) 
vid_player.play()
time.sleep(0.1)
vid_player.pause()

Any fix for this? I just want to display the video frame when seeked without playing it.

I got another error in tkVideoPlayer's scaled parameter, when we set scaled to True it works and the video fits with the label size, but I don't want stretching in videos so I set scaled to False but it is giving lots of errors. Can we fit the video on the label with original ratio but with other remaining portions as black/label color? And the set_scaled parameter is also not working.

Hello,

I love your package, however I am having some trouble implementing the .set_size() method in a working Tkinter mainloop, so if you could be so kind as to provide a minimal example of manual video size setting?

The problem is when I embed the video in the Tkinter window it only shows a corner of the video in a very small box. I manually set the size using this code:

vid_player = TkinterVideo( master=root,keep_aspect=False,scaled=True)
vid_player.set_size(size=(600,600))

I've come across an issue when using .play() and stop() in one function.

When creating buttons for each of the methods videoplayer.stop() and videoplayer.play(), everything works perfectly fine. But as soon as i combine them in one function, they don't work properly anymore:

directory = "/Users/..."
videofiles = [] # this is a list which gets filled with the video files in a specific folder
COUNT = 0
global videoplayer
global COUNT

def load_next_video():
    increment() # basic function to increase the COUNT variable by one, so it pulls the next object from the videofiles list
    videoplayer.load(r"{}".format(directory + "/" + videofiles[COUNT]))

def add_to_list():
    videoplayer.stop()
    load_next_video_()
    videoplayer.play()

I've kept out the rest of the code, which are only some buttons and basic pack statements.

When i use my add_to_list function behind a button, the video just keeps playing and does not change. Only when the video is fully played through and you click the button, a new video gets loaded. I want to be able to change the video with one button click, even if the video is not completely over yet. Does anyone have an idea how to fix this?

i'm using tkVideoPlayer to loop a video, but every time the video restart the ram usage continues to increase and reaches several gigabytes, is there any way to prevent this?

If you encounter any framerate-related issues, even after upgrading to the latest version, i.e the video being too fast or too slow, please comment under this. Before posting a comment make sure to test your video with other video players, (eg, VLC player), to make sure that it isn't related to hardware

tkVideoPlayer only seeks in seconds, but I want to seek the video based on frame number of video, can we do this with tkVideoPlayer and also the progress bar based on the number of frames?
