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.

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.

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.

Colorspace selection is currently supported by vo_gl, vo_vdpau, vo_xv and vf_scale, and all can change it at runtime (previously only vo_vdpau and vo_xv could). vo_vdpau now uses the same conversion matrix generation as vo_gl instead of libvdpau functionality; the main functional difference is that the "contrast" equalizer control behaves somewhat differently (it scales the Y component around 1/2 instead of around 0, so that contrast 0 makes the image gray rather than black). vo_xv does not support level conversion. vf_scale supports range setting for input, but always outputs full-range RGB. The value of the slave properties is the policy setting used for conversions. This means they can be set to any value regardless of whether the current VO supports that value or whether there currently even is any video. Possibly separate properties could be added to query the conversion actually used at the moment, if any. Because the colorspace and level settings are now set with a single VF/VO control call, the return value of that is no longer used to signal whether all the settings are actually supported. Instead code should set all the details it can support, and ignore the rest. The core will use GET_YUV_COLORSPACE to check which colorspace details have been set and which not. In other words, the return value for SET_YUV_COLORSPACE only signals whether any kind of YUV colorspace conversion handling exists at all, and VOs have to take care to return the actual state with GET_YUV_COLORSPACE instead.

input: handle mouse movement differently Before this commit, mouse movement events emitted a special command ("set_mouse_pos"), which was specially handled in command.c. This was once special-cased to the dvdnav and menu code, and did nothing after libmenu and dvdnav were removed. Change it so that mouse movement triggers a pseudo-key ("MOUSE_MOVE"), which then can be bound to an arbitrary command. The mouse position is now managed in input.c. A command which actually needs the mouse position can use either mp_input_get_mouse_pos() or mp_get_osd_mouse_pos() to query it. The former returns raw window-space coordinates, while the latter returns coordinates transformed to OSD- space. (Both are the same for most VOs, except vo_xv and vo_x11, which can't render OSD in window-space. These require extra code for mapping mouse position.) As of this commit, there is still nothing that uses mouse movement, so MOUSE_MOVE is mapped to "ignore" to silence warnings when moving the mouse (much like MOUSE_BTN0). Extend the concept of input sections. Allow multiple sections to be active at once, and organize them as stack. Bindings from the top of the stack are preferred to lower ones. Each section has a mouse input section associated, inside which mouse events are associated with the bindings. If the mouse pointer is outside of a section's mouse area, mouse events will be dispatched to an input section lower on the stack of active sections. This is intended for scripting, which is to be added later. Two scripts could occupy different areas of the screen without conflicting with each other. (If it turns out that this mechanism is useless, we'll just remove it again.)
