This enables a more C99-compliant implementation of printf et al.

The MinGW32 project is deprecating its old version macros.

The flag is not unconditionally added to CFLAGS either and the

Based on eeb975f5

The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.

Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.
