  • ffmpeg : Resampling with input channels greater than 2 unsupported ?

    13 septembre 2011, par user739711

    This question is already been asked but because that thread is old I am posting again.

    When a video file has 5.1 audio channels ffmpeg is not able to convert it to another format giving error :

    "Resampling with input channels greater than 2 unsupported"

    I saw some blogs saying I can modify the code and or patch ffmpeg for it.

    Any solution found yet ?

  • 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 :

    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.
