Comment 6 for bug 730159

The problem is that ffmpeg is spewing nearly a page-full of spurious error messages to the screen every time it is run, and/or that ffmpeg is mis-configured at build-time, and the library mismatch may be causing very difficult to find glitches or artefacts, bugs, or even outright crashes and protection faults.

If maintainers are confident that the configuration mismatch has no effect, there should be a patch to cmdutils.c to suppress the output in the PRINT_LIB_INFO macro. IMO arguments about whether upstream are being overly cautious, insufficiently clever about their library detection, or whatever, aren't at issue here (I have no opinion on it).

Having to scroll through nearly a page of spurious warnings is tedious.
