  • strncpy_s error when deploying ffmpeg streaming application on XP

    26 juillet 2013, par dagur

    I'm trying to deploy an application that uses ffmpeg to stream camera output to an XP machine. The application is written compiled with gcc mingw32 and runs fine on Windows 8. But on Windows XP I get the following error :

    The procedure entry point strncpy_s could not be located in the
    dynamic link library msvcrt.dll

    GCC command, excluding paths :

    g++ -o mingw\streamer.exe src\testffmpeg.o -lavformat -lavutil -lavcodec -lFlyCapture2_C_v100

    Dependency walker shows the following :
    Depedency Walker

    How can I work around this strncpy_s problem ? It seems to be ffmpeg which uses this function is msvcrt. I used the windows binaries they provided. I'd rather not have to compile the library myself, as it has a huge set of dependencies.

  • What is wrong with the following ffmpeg command

    14 août 2013, par Brad

    What is wrong with the following ffmpeg command. Originally this had -sameq instead of the -qscale:a 0

    Command :

    ffmpeg -loglevel debug -threads 4 -i sample-in.mpg -ss 00:00:01 -t 00:00:05 -f image2 -y sample-frames/frame%d.png -acodec copy -qscale:a 0  -y sample.mp3

    I found the code above from : http://kwlug.org/node/854
    I did a few edits removing the -sameq and replacing it with -qscale:a 0 which probably is wrong.
