core: redo how codecs are mapped, remove codecs.conf Use codec names instead of FourCCs to identify codecs. Rewrite how codecs are selected and initialized. Now each decoder exports a list of decoders (and the codec it supports) via add_decoders(). The order matters, and the first decoder for a given decoder is preferred over the other decoders. E.g. all ad_mpg123 decoders are preferred over ad_lavc, because it comes first in the mpcodecs_ad_drivers array. Likewise, decoders within ad_lavc that are enumerated first by libavcodec (using av_codec_next()) are preferred. (This is actually critical to select h264 software decoding by default instead of vdpau. libavcodec and ffmpeg/avconv use the same method to select decoders by default, so we hope this is sane.) The codec names follow libavcodec's codec names as defined by AVCodecDescriptor.name (see libavcodec/codec_desc.c). Some decoders have names different from the canonical codec name. The AVCodecDescriptor API is relatively new, so we need a compatibility layer for older libavcodec versions for codec names that are referenced internally, and which are different from the decoder name. (Add a configure check for that, because checking versions is getting way too messy.) demux/codec_tags.c is generated from the former codecs.conf (minus "special" decoders like vdpau, and excluding the mappings that are the same as the mappings libavformat's exported RIFF tables). It contains all the mappings from FourCCs to codec name. This is needed for demux_mkv, demux_mpg, demux_avi and demux_asf. demux_lavf will set the codec as determined by libavformat, while the other demuxers have to do this on their own, using the mp_set_audio/video_codec_from_tag() functions. Note that the sh_audio/video->format members don't uniquely identify the codec anymore, and sh->codec takes over this role. Replace the --ac/--vc/--afm/--vfm with new --vd/--ad options, which provide cover the functionality of the removed switched. Note: there's no CODECS_FLAG_FLIP flag anymore. This means some obscure container/video combinations (e.g. the sample Film_200_zygo_pro.mov) are played flipped. ffplay/avplay doesn't handle this properly either, so we don't care and blame ffmeg/libav instead.

video, options: implement better YUV->RGB conversion control Rewrite control of the colorspace and input/output level parameters used in YUV-RGB conversions, replacing VO-specific suboptions with new common options and adding configuration support to more cases. Add new option --colormatrix which selects the colorspace the original video is assumed to have in YUV->RGB conversions. The default behavior changes from assuming BT.601 to colorspace autoselection between BT.601 and BT.709 using a simple heuristic based on video size. Add new options --colormatrix-input-range and --colormatrix-output-range which select input YUV and output RGB range. Disable the previously existing VO-specific colorspace and level conversion suboptions in vo_gl and vo_vdpau. Remove the "yuv_colorspace" property and replace it with one named "colormatrix" and semantics matching the new option. Add new properties matching the options for level conversion. 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. To be changed in later commits: add missing option documentation.
