android videos/pics issues

[purushottam yadav]

Two issues I am facing  .

1) I need a widget to display both images  and videos from link over internet  

I am using below widget but display is slow and default images are appearing in between the video play .

I dont know if it is because of my slow  internet connection or something else .

suggest me something  .

from kivy.uix.image import AsyncImage

class Video__(Video , AsyncImage ):

    def __init__(self, **kw):
        super().__init__(**kw)

 .

2)

what is below error ,  how to solve it ?

Is ffpyplayer in requirements?

[purushottam yadav]

yes

# comma separated e.g. requirements = sqlite3,kivy
requirements = python3,kivy==2.0.0,ffpyplayer,libshine,libx264,ffpyplayer_codecs , kivymd , sdl2_ttf==2.0.15 ,thumb_gen ,   plyer ,  pyzbar, libzbar,  pillow, pyjnius  , kivmob ,kivy_garden.mapview , requests  , ffmpy ,  urllib3 , chardet , idna , infomedia ,  boto3 , botocore , dateutil , jmespath , simplejson  , certifi

The Video class is derived from Image, will display images and will accept a URL as a source.  Just use the Video class.

with your suggestions "  The Video class is derived from Image, will display images and will accept a URL as a source.  Just use the Video class. "  

I made below    class Video___(Video):   to    display images , Videos  and  to  accept a URL as a source . it is displayng  images   from  both url and local   , but not Videos  from  both url and local . 

 app crashes when clicked on widget   in all cases . 

in case of video from url , i get below error and red cross mark displayed in place of    video and no crash of app   .

Do you have the appropriate video player installed?

 

This works on Windows with Gstreamer installed.

Use:  python -m pip install "kivy[full]"

 

 

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


kv = """
AnchorLayout:
    TouchVideo:
        size_hint: None, None
        size: 400, 200
        source: 'http://clips.vorwaerts-gmbh.de/VfE_html5.mp4'
"""


class TouchVideo(Video):
    def on_touch_down(self, touch):
        if self.collide_point(*touch.pos):
            self.state = 'play' if self.state == 'stop' else 'stop'
            return True
        return False


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


EvalTouchVideoApp().run()

I don't think I want to get involved in this one, too many moving parts!

But:

1)  " [ERROR  ] [Image       ] Error loading "  I think these messages are noise. There is an issue somewhere, but it doesn't matter.

2)  I suggest looking at the Android log in the startup phase, where it logs what drivers are loaded (just like Kivy on PC but different drivers). I don't know well enough what things should be, but I wonder about video_ffmpeg.

3) I looked to see if I have any Android examples, just one and it uses the VideoPlayer widget and has videos pushed to it. So not what you want. Its here if you want to look https://github.com/Android-for-Python/share_receive_example/blob/main/main.py

4) There is some issue with Kivy's Async* classes on Android. I don't know enough to explain or know if it is significant. I always use requests and a thread to download stuff and that is reliable.

This may be at least part of the issue    https://github.com/kivy/kivy/pull/7994
Hopefully some dev will merge the PR
