Bug ID: 57269
           Summary: wine-9.19 build with ffmpeg fails in winedmo in Ubuntu
                    20.04
           Product: Wine
           Version: 9.19
          Hardware: x86-64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

If built with ffmpeg, the build fails in Ubuntu 20.04 with:

dlls/winedmo/unix_private.h:30:10: fatal error: libavcodec/bsf.h: No such file
or directory

No problem with any of the other distros we package. I was able to build the
9.19 packages for 20.04 without ffmpeg.
