  • Android FFmpeg sometimes works and sometimes crashes

    20 novembre 2013, par Pawel Cala

    I compiled FFmpeg for Android ( https://gitorious.org/android-ffmpeg ) but when I'm trying to do some operations ( f.e filters cropping, transpose, trim etc ) it crashes in 5 on 10 cases.
    Error logs are not the same so I assume that it might be caused by memory issues.
    I'm using OSX, NDK android-ndk-r9b : darwing x86_64.
    Native ffmpeg method is passing args to ffmpeg.c main method. It's executed in AsyncTask in Activity.
    Thanks in advance

    EDIT :
    I forgot to mention that programs algorithm runs like that :
    Press Button - > Open Camera Intent - > Start recording - > After recording copy file to project folder ( on SD card ) - > Open edit activity + Start asynctask

    EDIT2 :
    Tested on HTC ONE with different video resolutions

    20 mars 2015, par jagdish

    I read the tutorial of ffmpeg libray to combine the image into audio file.but is more complex and getting error environment value is null.I googled a lot but didn’t found any solution.

    Thanks in advance....
