  • ffmpeg fade filter installed but not working ?

    4 novembre 2011, par Astha

    I have php 5.1.6 running on my CentOS 5 server running Apache 2.2.3

    I installed ffmpeg library and my aim is to covert a set of images into a slideshow with the fadein/fade out effect per image swap.

    Command ffmpeg says :

    and command ffmpeg -filters prints :

    firstly my ffmpeg was not having fade filter because it was giving error

    fade: filter not found

    so i installed the patch created vf_fade.c and made corresponding changes to Makefile and allfilters.c file of directory libavfilters in ffmpeg. configured it again then also ran commands 'make' and 'make install' Restarted the server but still its showing the same error

    fade: filter not found

    what should i do next ? if any more details needed please ask and all the helps and ideas and links will be appreciated.

  • 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
