After adding colorspace support to xine-lib, I insist in proper

As for intra-refresh it is just a commodity.

libx264 has a few data exports which require X264_API_IMPORTS
to be defined if we link to libx264 dynamically on Windows.

In a similar fashion to how we handle our compat snprintf
implementation, if we define it all the time, the compiler
will first try and link to __imp_x264_symbol_name, and failing
that, as in the case of a static libx264, will attempt to link
to the non-prefixed symbol, which has already been pulled in by
other x264 functions' object files.

It is a shortcut to set all the params using x264_param_parse,
makes simpler importing settings from other software using x264.

By default libav sets it to 3/4 while x264 sets it to 9/10.

You should not need to enable verbose logging and all the output that comes
with it in order to get things like the obtained bitrate from a first
pass encode. Many things parse this output.

Also, since it is marked as info in libx264, it should be marked as
info in libavcodec as well.

This reverts commit 911519ca.

AV_LOG_INFO is more geared towards messages to be read by the user, the
statistics shown by libx264 with X264_LOG_INFO are more useful at the
debugging level.
