This did random things with some image formats, including 10 bit
formats. Fixes the mp_image_clear() function too.
This still has some caveats:
- doesn't clear alpha to opaque (too hard with packed RGB, and is rarely
needed)
- sets luma to 0 for mpeg-range YUV, instead of the lowest possible
value (e.g. 16 for 8 bit)
The memcpy_pic() function had a rather dangerous optimization: when the
limit2width flag was not set, it was allowed to overwrite the data
between the last pixel of a line and the first pixel of the next line
(i.e. write over the stride padding). That was also the reason why there
are so many whacky names for this function (memcpy_pic, my_memcpy_pic,
memcpy_pic2).
Kill this optimization, and never overwrite the stride padding. The code
doing this can still be used if there's no stride padding at all,
though.
Also use the name memcpy_pic for the proper function. Now it should be
rather clear that my_memcpy_pic and memcpy_pic2 are compatibility
aliases. They should go away over the time.
Tis drops the silly lib prefixes, and attempts to organize the tree in
a more logical way. Make the top-level directory less cluttered as
well.
Renames the following directories:
libaf -> audio/filter
libao2 -> audio/out
libvo -> video/out
libmpdemux -> demux
Split libmpcodecs:
vf* -> video/filter
vd*, dec_video.* -> video/decode
mp_image*, img_format*, ... -> video/
ad*, dec_audio.* -> audio/decode
libaf/format.* is moved to audio/ - this is similar to how mp_image.*
is located in video/.
Move most top-level .c/.h files to core. (talloc.c/.h is left on top-
level, because it's external.) Park some of the more annoying files
in compat/. Some of these are relicts from the time mplayer used
ffmpeg internals.
sub/ is not split, because it's too much of a mess (subtitle code is
mixed with OSD display and rendering).
Maybe the organization of core is not ideal: it mixes playback core
(like mplayer.c) and utility helpers (like bstr.c/h). Should the need
arise, the playback core will be moved somewhere else, while core
contains all helper and common code.
