  • How to tell if ffmpeg errored or not ?

    12 juin 2015, par dvdmn

    The Situation :
    I’m using ffmpeg (via .net) to save video files. I can get the output from ffmpeg but I dont know how can I customize the output to have better result.

    My Problem :
    My problem is, there is no certain difference between successful and failed operation.

    last line of success :

    video:1006kB audio:134kB subtitle:0 global headers:0kB muxing overhead 0.943510%

    last lines from fails

    c :\x\test-9-8/30/2012-9:29:56-AM.mp4 : Invalid argument

    rtmp ://cdn.tv/cdn-live39/definst/stream01 : Unknown error occurred

    My Question :
    Is there an option (or command line parameter) to add some sort of return code (200 : success, 500 : error, etc)

    Thanks !

    PS : I saw this topic How to tell if ffmpeg errored ? but there is no number before/after last line. I think the last version doesnt have number anymore.

    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 $ ?

    /home/mehmet/Android_NDK_r4/build/prebuilt/linux-x86/arm-eabi-4.4.0/bin/../lib/gcc/arm-eabi/4.4.0/../../../../arm-eabi/bin/ld : crt0.o : No such file : No such file or directory collect2 : ld returned

    I have checked the flags as well, flags seem ok or I can't see the faulty line. Above you may find the build script I am using.

    Problem solved. It was just a mistake related to typos. It works well now.
