Hello. I'd like to play a video on my app on android, I tried with videoplayer, it works but doesn't load the video simply open theUI but not thevideo
26 octobre 2022, par AbdulI'd like to play a video on my app on android, I tried with videoplayer, it works but doesn't load the video ( simply open the UI but not the video).


I found out i may need ffpyplayer so I changed buildozer requirements :
requirements = python3,kivy, android,ffpyplayer


but buildozer failed to build apk when i added ffpyplayer and ffmpeg in buildozer.spec file in requirement.

ffmpeg encoding leaves me with blank space at the end where the video pauses and there is nothing ahead
6 novembre 2022, par Nisarg DesaiI was trying to slice some of the video being played and clip it in mpv.net using a .lua script which uses ffmpeg to encode the webm output. ffmpeg sometimes leaves some seconds blank and without any video/audio ahead while clipping from source. Is there any solution to this ?


The code for the script is given below (was taken from here https://github.com/occivink/mpv-scripts) :


local utils = require "mp.utils"
local msg = require "mp.msg"
local options = require "mp.options"

local ON_WINDOWS = (package.config:sub(1,1) ~= "/")

local start_timestamp = nil
local profile_start = ""

-- implementation detail of the osd message
local timer = nil
local timer_duration = 2

-- folder creation if it doesnt exist
function exists(file)
