error: unknown type name 'VIDEO_STREAM_CONFIG_CAPS'

Hi,

I'm getting this error when trying to compile FFmpeg with the latest MinGW-w64:

make: *** [libavdevice/dshow.o] Error 1

I posted on the MinGW-w64 mailing list and was told this:
That's because your libavdevice/dshow.h is misfortunately named
"dshow.h". It is attempting to include system's dshow.h by an
#include directive, which is wrong: you should use #include_next
instead (or rename the header). If system's dshow.h is included,
it includes strmif.h by itself and the missing data type will be
there.

I'm using the latest FFmpeg git source.

I can provide any further information needed, a quick fix for this would be much appreciated.

Best regards,

Kyle Schwarz

Is this a regression or did compilation never succeed on MinGW64?

Replying to cehoyos:

I used to have no issues compiling FFmpeg before I updated my MinGW-w64 tool chain.

I suspect the problem occurs due to the libavcodec source directory with the private dshow.h header ending somehow in the systems headers search path.
A workaround would be to rename libavcodec/dshow.h.
I think we should rename the header to make it more robust. Can you submit a patch for that ? (i cant easily test dshow so its better you make this change and test it instead of me blindly doing it)

thanks

[michael]

Patch applied (without the configure change which looked wrong)

please test!
