FFMPEG : Merge Image and Audio Convert into Video in android using FFMPEG library
30 janvier 2014, par Nitish Singlai want to convert images into video in android using FFMPEG,still now i compiled the library successfully,and also get Libffmpeg.so.
Using Platform : UBUNTU,Eclipse
My problem is- when i use this library command too convert video into images through Java code i mean through my Activity i got Error-
JAVA.IO.EXCEPTION.Enable to execute .Exec() command
But if i exceute this command through CMD then my video file is created successfully.
i want to know whats the problem behind it,i am searching from 2 days on it,but could not get the solution,i thing its problem of Execute Permission In android.Plzzz help me,,,or tell me is it possible to in android to make a video file using FFMPEG.Code :
