i mean how to solve video texture error ....?

[Elliot Garbus]

You can ignore this error.

If you trace through the video widget you will see the code first attempts to load a still image, if that fails, then it will load the video.  You can use the video widget to display a slide show of jpeg images or mix a list of still images and videos.

[Elliot Garbus]

I should add – if you load a still image with the Video widget, you  will not see the error.

[Degenerate Tech]

how ? can you give me a simple example ?

[Elliot Garbus]

The example below plays a list of videos or images from the list video_list.  Replace the filenames with your own.  You will see in the log that there are no error for the still images, and errors for the videos.

 

 

from kivy.app import App
from kivy.uix.video import Video
from kivy.lang import Builder

kv = """
BoxLayout:
    orientation: 'vertical'
    Player:
        id:player
    BoxLayout:
        size_hint_y: .1
        Button: 
            text: 'play'
            on_release: player.state = 'play' 
"""

video_list = ['IMG_1853.jpg',
              'Hand Washing - 34091.mp4']  # Put you content in this list.

class Player(Video):
    def __init__(self, **kwargs):
        self.v = 0
        super().__init__(source=video_list[0], state='stop', **kwargs)

    def on_eos(self, *args):
        print(f'on_eos: {self.eos} loaded: {self.loaded}, state: {self.state}')
        if self.eos:
            self.v += 1
            if self.v == len(video_list):
                print('End of playlist')
                self.v = 0
                return
        self.source = video_list[self.v]
        self.state = 'play'  # must set state to play for video to be loaded

    def on_loaded(self, *args):
        # print('*' * 80)
        print(f'loaded: {self.loaded}')


class VideoPlayerApp(App):
    def build(self):
        return Builder.load_string(kv)


if __name__ == '__main__':
    VideoPlayerApp().run()

[Degenerate Tech]

&. can I make my coustom video player? by using button ,slider etc ?

[Elliot Garbus]

Yes,  You can make your own custom video player using buttons and sliders.

The video will size automatically to fit the size of the enclosing layout.

You can go fullscreen – but I don’t see an easy way to change the aspect ratio.

If you need to change the aspect ratio, it might be useful to look at the source code for Image and look how keep_ratio (especially keep_ratio: False) works to change the aspect ration of a still image.

give me a direction ...I am new in Python

[Elliot Garbus]

Use glob to get a list of video files. Put a list of file names on buttons in a scroll view, or recycle view, on the button press, play a video.

Hi @Elliot Garbus, Can you tell me how should I install ffmpeg on android such that I should get this output correctly.

def test_ffmpeg():

try:

import subprocess

print(subprocess.check_output(['ffmpeg', '-version']))

except Exception as e:

print(e)

print('==> ffmpeg is not good :(, nooooooooooooo')

else:

print('==> ffmpeg is good :)')

test_ffmpeg()

Please reply ASAP, I am stuck on this since many days.

Thanks

I have no experience with Android.   Robert, Do you know?

 

Take a look at the source for the kivy core video player to see how kivy uses ffpyplayer.

https://github.com/kivy/kivy/blob/master/kivy/core/video/video_ffpyplayer.py

[Robert Flatt]

Assuming ffmpeg is specified in requirements. There are I think two issues with the approach (meaning its not going to work):

1) where would the executable be? There is no $PATH

2) I think the recipe says the executable is not built.

Look in

https://github.com/kivy/python-for-android/blob/develop/pythonforandroid/recipes/ffmpeg/__init__.py

Line 84:

# disable binaries / doc
 flags += [
 '--disable-programs',
 '--disable-doc',
 ]

However you know what version of ffmpeg was used because you built it !  Also in requirements one can specify a version of a package (e.g kivy==2.0.0rc3). So  ffmpeg==whatever   HOWEVER I can't tell you if version WHATEVER will catually build on Android.
