What version of the product are you using? On what operating system?
0.6rc3 windows xp + latest mingw and ubuntu 9.04

How do you compile a working windows version?
regards

Out of interest - what are your configure options?

I get a working FFmbc-v0.6rc3 on Ubuntu 10.04 with this (although I have to 
edit the output config.mak to remove -Werror=missing-prototypes from the end of 
CFLAGS line 29)

PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig \
./configure \
    --cpu=i686 \
    --arch=i686 \
    --prefix=$PREFIX \
    --target-os=mingw32 \

This may help you:
http://ffmpeg.arrozcru.org/forum/viewtopic.php?f=1&t=1688
.................
Found a workaround:

adding:

Code: Select all
    static char *strCopy(const char *str)
    {
        int n = strlen(str) + 1;
        char *dup = malloc(n);
        if(dup)
        {
            strcpy(dup, str);
        }
        return dup;
    }

and replacing all the strdup with strCopy calls works,..

I'll fix this in rc4.

Is there a windows build?

Hi,

I was able to compile ffmbc with mingw under windows.

However I found that using the target xdcamhd422 was configured as 16 bit audio.
The spec for xdcamhd422 is 24 bit audio.

in ffmbc.c i changed the audio codec.

else if(!strcmp(arg, "xdcamhd422")) {
        target = "xdcamhd422";

        opt_video_codec("mpeg2video");
        opt_audio_codec("pcm_s24le");

Next week I will analyse the IMX and xdcamhd files with a profesional media 
analyser. Baton.

Should be fixed in rc4, can you please double check ?

Hi,
strdup compile error under MinGW seems to be fixed in:
libavfilter/libmpcodecs/vf_detc.c
and
libavfilter/libmpcodecs/vf_divtc.c
BUT left(only) in ffmbc.c :
ffmbc.c:3251:9: error: implicit declaration of function 'strdup'

_____________________________________

Arf, sorry about that, I updated the tarball in downloads.

Many thanks!
Now compiles without error under MinGW:)
