cannot able to load the live video stream

[Sandesh Chand]

Hello All,

Actually, I want to display the video stream in my app. I have created the apk file using bulldozer. In my desktop, the programs runs well and video is also displaying. but when I installed the apk  file in mobile. the app is running but no  video stream is displayed.

This is the code snippet of source. I am using the ip camera as a source.

I tried many times but couldn't able to display ?

The code snippet as follows

I don't know for sure but it is possible this is the issue addressed by this possible fix https://github.com/kivy/kivy/pull/7994

As you can see It is a work in progress. And I don't know anything about its future inclusion.

It is also possible Android has become picky about not using https, but that just brings you back to the issue above.

I am getting error  from ffpyplayer.

Dear Support team, 

Actually, i  want to display the video video stream in my app.

This is the code snippet of source. I am using the ip camera as a source. My aim  is to display the live video stream in my app. I can able to display the video in the desktop. But in the android mobile, the app is running without displaying the video.

I tried many times but couldn't able to display ?

 please check the spec file , I am stuck in this work  from last week.

I am creating the apk file from google colab using buildozer.

Please find the app log file and spec file of app.

Waiting for your support

No idea if any of these are the issue you face (its wildly optimistic to throw your app over a wall and hope somebody will debug it for you).

Looking at your buildozer.spec

- I suggest you don't pin the Python version, better to use the default.

- Don't add python-for-android to requirements, it not something imported by your app

- The 'requests' dependencies are https://github.com/Android-for-Python/Android-for-Python-Users#kivy-widget-dependencies

I'm surprised you can load a jpg with ffpyplayer, but that doesn't mean you can't.

(In this situation I'd test this with a jpg file locally on the Android device, this might explain the error message you see)

I'm surprised you can to do real time streaming with http, but that doesn't mean you can't.

(I would have expected rstp, but I suspect the default build of ffpyplayer does not support it,  so some recipe customization may be required.)

I have not done what you want to do, so I am not able to offer specific advice.

Dear Robert,

Thanks for the message.

During running the code i got the following the following error from adb tool

09-13 20:52:06.329 19112 19307 I python : [ERROR ] [ffpyplayer ] https://192.168.178.51:8080/shot.jpg: Invalid data found when processing input

Is there any problem of permission ?
