We could handle directories as descriptors, but we currently don't. In
the mean time, we had better show an error than generate corrupt
playlist entries.

"-" is now converted to "fd://0" by the input code. And file:///- really
means /- (which is a valid file name).

venc=x264{slices,slice-max-size,slice-max-mbs} options are there now

libx264 gives dts-value, but we need to calculate initial delay, so dts doesn't
go < VLC_TS_0.

Tell how many frames are still left on libx264 buffer when we close encoder

Only set BLOCK_FLAG_TYPE_I on IDR-frames on X264_BUILD < 83 and only those
which have b_keyframe on X264_BUILD >= 83.

We assume it is present in plenty of places anyway

This requires support for fdopendir(). One open() and fstat() calls per
input file are avoided. Ok, this is not such a major improvement).
This should also work around brain-damaged file system drivers such as
Linux HFS+, whereby opendir() succeeds on regular files.

directory does not register the "fd" shortcut, so the standard input
case should not occur.

(You can't read ahead a pipe)

InputSourceInit() does it globally already

We have too much false positive with this script.
Feel free to revert or to remove.

Attempt to run scripts in share/lua/meta/fetcher.

The result of meta fetching is not cached (except the artwork), but this could be an envisionned goal for the media library.

fix crash when switching phonon backends on the fly, remember to stop libvlc media player before releasing it
