I am compiling opencv 3.0.0 but I get multiple "xxx was not declared in this scope" errors when compiling cap_ffmpeg_impl.hpp file. (E.g pix_fmt_yuv422p, codec_pix_fmt) I have built ffmpeg using the --enable-shared option (as advised on other forums) and ffmpeg appears to run without any problems.

If a patch has been issued for this please let me know. Any help would be greatly appreciated

  • can you give us the exact error msges ?
  • which os / compiler is it ?
  • can you try latest github master src, instead of opencv3.0 (which is already half a year away)

I used 3.0 because I don't have much experience with linux and the tutorials I had found used that. Turns out that using 3.1 made the problem go away - the compilation completed OK. Thanks for your help
