  • FFMPEG preset is not found ? Linux Cent OS 6

    25 août 2012, par Darius

    I ran this command

    I alos tried with -vpre libx264-ipod640 and still no luck. I get preset libx264-ipod640 is not found.... Do i have to enable presets somehow ? ffmpeg — enable presets ? or something ?

  • no c compiler found libx264 build [closed]

    24 août 2012, par kerim yucel

    I have been trying to build ffmpeg for Android and I have managed to do so by using roman10's tutorial.

    However, I needed x264 and I enabled libx264 in the configurations but it wasn't able to find the library. A quick internet search led me to the answer that I have to build x264 seperately and include it to ffmpeg config by editing ExternalLibs flags.

    Currently I am using this script to build x264. Everything is fine except the fact that the error saying "No working C compiler is found" pops up. I have updated and installed build-essential and my gcc version is up to date.

    Any help will be appreciated. Thanks a lot.

    P.S. I am using ndk 4 just to make everything compatible with the tutorial link given above. I am running Ubuntu with VirtualBox from Windows 7.

    Edit : I have been trying this tutorial as well, I am getting the same error along with unknown options error for each configuration options.

    Another edit :
    I have tried this code and obtained the following.

    echo 'int main() return 0 ;' > main.c && arm-eabi-gcc main.c || echo $ ?
