video: use libavutil pixel format descriptors Replace the internal pixel format stuff with code that queries the libavutil list of pixel format descriptors. Trying to map IMGFMT_IS_RGB() etc. turned out extremely hacky.

#include <assert.h>
video: decouple internal pixel formats from FourCCs mplayer's video chain traditionally used FourCCs for pixel formats. For example, it used IMGFMT_YV12 for 4:2:0 YUV, which was defined to the string 'YV12' interpreted as unsigned int. Additionally, it used to encode information into the numeric values of some formats. The RGB formats had their bit depth and endian encoded into the least significant byte. Extended planar formats (420P10 etc.) had chroma shift, endian, and component bit depth encoded. (This has been removed in recent commits.) Replace the FourCC mess with a simple enum. Remove all the redundant formats like YV12/I420/IYUV. Replace some image format names by something more intuitive, most importantly IMGFMT_YV12 -> IMGFMT_420P. Add img_fourcc.h, which contains the old IDs for code that actually uses FourCCs. Change the way demuxers, that output raw video, identify the video format: they set either MP_FOURCC_RAWVIDEO or MP_FOURCC_IMGFMT to request the rawvideo decoder, and sh_video->imgfmt specifies the pixel format. Like the previous hack, this is supposed to avoid the need for a complete codecs.cfg entry per format, or other lookup tables. (Note that the RGB raw video FourCCs mostly rely on ffmpeg's mappings for NUT raw video, but this is still considered better than adding a raw video decoder - even if trivial, it would be full of annoying lookup tables.) The TV code has not been tested. Some corrective changes regarding endian and other image format flags creep in.

Rename directories, move files (step 2 of 2) Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)

options, codecs.conf, img_format: unify imgfmt name handling Remove the duplication of image format name lists from codec-cfg.c and img_format.c. Remove the list of "long" image format names from img_format.c. One user visible change is that now mplayer won't print "long" format names anymore: e.g. instead of "Planar 420P 10-bit little-endian", the name "420p10le" is used. This is consistent with the names used by the option parser, and also less noisy. Partially based on mplayer2 commit f98e47574de15, with some differences.

video: decouple internal pixel formats from FourCCs mplayer's video chain traditionally used FourCCs for pixel formats. For example, it used IMGFMT_YV12 for 4:2:0 YUV, which was defined to the string 'YV12' interpreted as unsigned int. Additionally, it used to encode information into the numeric values of some formats. The RGB formats had their bit depth and endian encoded into the least significant byte. Extended planar formats (420P10 etc.) had chroma shift, endian, and component bit depth encoded. (This has been removed in recent commits.) Replace the FourCC mess with a simple enum. Remove all the redundant formats like YV12/I420/IYUV. Replace some image format names by something more intuitive, most importantly IMGFMT_YV12 -> IMGFMT_420P. Add img_fourcc.h, which contains the old IDs for code that actually uses FourCCs. Change the way demuxers, that output raw video, identify the video format: they set either MP_FOURCC_RAWVIDEO or MP_FOURCC_IMGFMT to request the rawvideo decoder, and sh_video->imgfmt specifies the pixel format. Like the previous hack, this is supposed to avoid the need for a complete codecs.cfg entry per format, or other lookup tables. (Note that the RGB raw video FourCCs mostly rely on ffmpeg's mappings for NUT raw video, but this is still considered better than adding a raw video decoder - even if trivial, it would be full of annoying lookup tables.) The TV code has not been tested. Some corrective changes regarding endian and other image format flags creep in.

img_format: change meaning of MP_IMGFLAG_PLANAR This used to mean that there is more than one plane. This is not very useful: IMGFMT_Y8 was not considered planar, but it's just a Y plane, and could be treated the same as actual planar formats. On the other hand, IMGFMT_NV12 is partially packed, and usually requires special handling, but was considered planar. Change its meaning. Now the flag is set if the format has a separate plane for each component. IMGFMT_Y8 is now planar, IMGFMT_NV12 is not. As an odd special case, IMGFMT_MONO (1 bit per pixel) is like a planar RGB format with a single plane.

draw_bmp: better way to find 444 format Even though #ifdef ACCURATE is removed, the result should be about the same. The fallback is only used by packed YUV formats (YUYV, NV12), and doing 16 bit for them instead of 8 bit is not useful. A side effect is that Y8 (gray) is not converted drawing subs, and for alpha formats, the alpha plane is not removed. This means the number of planes after upsampling can be 1-4 (1: gray, 2: gray+alpha, 3: planar, 4: planar+alpha). The code has to be adjusted accordingly to work on the color planes only. Also remove the workaround for the chroma shift 31 hack.
