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 (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 are played flipped. ffplay/avplay doesn't handle this properly either, so we don't care and blame ffmeg/libav instead.

-Understanding MPlayer's etc/codecs.conf File
-MPlayer features a very flexible codec architecture which allows it to
-use its own open source codecs, as well as open source libraries, Win32
-codec DLLs and other binary codec modules. To the MPlayer user, the
-most visible piece of this architecture is the etc/codecs.conf file. This
-is a text-based configuration file that controls which MPlayer components
-are in charge of handling particular compressed data formats.
-The codecs.conf file is stored either in a shared directory for all system
-users to access, or in the .mplayer directory in a user's home
-directory. When MPlayer starts, it first looks for a codecs.conf file in a
-user's home directory. Failing that, it searches for the shared file. If
-no codecs.conf file is found MPlayer falls back on its internal hardcoded
-configuration. If the file is present but has syntax errors, MPlayer will
-report the error.
-The codecs.conf file is really quite simple. It is simply a collection of
-codec definition blocks that define how different media types should be
-handled. There are a number of keywords that can occur in a block. Not all
-of them are required and no particular order is enforced.
-Editing codecs.conf
-You can edit codecs.conf using your favorite text editor. Anything that
-comes after a semicolon (;) on a line is regarded as a comment. For
-; this is a comment
- format 0x34616d69 ; "ima4" (MOV files)
-The codec blocks can be in any order; the file parser doesn't
-care. However, they are organized in a particular order for the benefit of
-human readers. For example, all of the open source decoders that MPlayer
-implements natively are grouped in one section.
-Release Number
-Your codecs.conf now requires a release number to avoid codec release
-incompatibilities. The format is simple: (YYYYMMDD)
-release 20020520
-Whenever changes are made to the codecs that *require* an updated
-codecs.conf, then MPlayer will no longer accept outdated versions.
-It is not recommended to change this line unless you know exactly
-what you are doing.
-Video Codecs
-Let's jump right in with an example. Here is an example video codec block:
-videocodec indeo5ds
- info "Intel Indeo 5"
- status working
- fourcc IV50,iv50
- driver dshow
- dll "ir50_32.dll"
- guid 0x30355649, 0x0000, 0x0010, 0x80, 0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, 0x71
- out YV12
- out YUY2
- out BGR32,BGR24,BGR16,BGR15
-This is a particularly full-featured video codec. The "videocodec" keyword
-identifies the fact that this is the start of a new video
-codec. "indeo5ds" is MPlayer's unique name for the codec. You have to use
-this name with the -vc/-ac option.
-The next line has the keyword "info" which specifies a human-readable
-comment accompanying this codec. This is printed by -vc help / -ac help.
-The "status" keyword carries information about the codec's functional
-status. MPlayer currently recognizes 4 status levels: working, buggy,
-crashing, and untested. When it gets to codec auto-selection, it tries
-untested first (to force users to test it for us and report results :)),
-then working and finally buggy ones. Codecs marked crashing won't be tried,
-unless explicitly (-vc/-ac) selected.
-The next line lists 4-character codes (FOURCCs) that are associated with
-this codec. There can be more than one FOURCC specified on a fourcc line
-as long as they are separated with a comma. There can also be multiple
-fourcc lines in the codec. A second fourcc can also be given, separated
-with a space. MPlayer will replace the original fourcc in the headers with
-this one before opening the codec. It's useful for win32 codecs checking for
-the fourccs.
-The "driver" keyword associates this codec with an internal MPlayer
-decoder module. MPlayer has a module named "dshow" that handles data
-encoded by the codec. See -vfm help / -afm help for the available module list.
-The "dll" keyword specifies which Win32/XAnim/Real/Quicktime binary
-module needs to be loaded. It's also used to specify which FFmpeg codec
-to load. The list of FFmpeg codecs can be found in libavcodec/allcodecs.c.
-The "guid" keyword identifies a 16-byte Microsoft GUID that some media
-files use to identify codecs. Used only for win32 dshow and DMO codecs.
-The "out" keyword identifies which output format the decoder is known
-to provide. Just like the fourcc line, there can be multiple out lines or
-multiple comma-separated output formats on the same line. The output
-formats should be listed in order of preference.
-The outfmt values can be followed by one or more flags, like flip, noflip,
-static, query. The flags are defined as follows:
- If this flag is set for a given format, then o_bih->biHeight will NOT be
- set to -bih->biHeight, i.e. the image will be decoded upside-down.
- Used only by vfw and vfwex codecs.
- This flag is ignored (no effect) without "flip" being set!
- If this flag is set, it means the codec doesn't decode upside-down,
- although it's told to do so.
- This flag is required for the old win32 ms-mpeg4 vfw codecs, including
- MP42 and DIV3 (DivX 3.11). These DLLs actually support YUV formats,
- but the query/begin functions are buggy and don't accept YUV fourccs
- (the decode function accepts it and works well!)
- If this flag is set, then o_bih->biCompression will be set to 0 for
- the initialization for the YUV modes. Used only by vfw/vfwex codecs.
- This flag is used to control VDCTRL_QUERY_FORMAT for vfw/vfewx codecs.
- If this flag is set, the control() will query the codec for the csp
- support, otherwise it will assume a constant csp table. Required for
- some DLLs (like huffyuv, CRAM).
- This flag forces STATIC (instead of TEMP) buffer allocation for the codec.
- Used for some very old DLLs like Indeo 3 and for some XAnim codecs like
- cinepak. See dr-methods.txt for details on buffer types.
-The "in" keyword -- UNDOCUMENTED
-Audio Codecs
-Here is an example of a rather full-featured audio codec block:
-audiocodec mp3
- info "MPEG layer-2, layer-3"
- status working
- comment "Optimized to MMX/SSE/3Dnow!"
- format 0x50
- format 0x55
- format 0x33706d2e ; ".mp3" CBR/VBR MP3 (MOV files)
- format 0x5500736d ; "ms\0\x55" older mp3 fcc (MOV files)
- driver mp3lib
- dll "mp3lib (mpglib)"
- flags seekable
-Many of the keywords are the same as a video codec block. However, we see
-a few that we haven't seen before. The "comment" keyword identifies
-another human-readable note for this codec.
-The "format" keyword performs a similar job as the fourcc line. However,
-since certain media file formats (notably AVI) identify audio formats with
-16-bit numbers rather than 32-bit FOURCCs, it's necessary to use this
-convention to accommodate them. However, as shown in this example, FOURCCs
-can also be specified with the format keyword as long as they're converted
-to their hex representation. It's important to note that this can be
-useful for video codecs as well if a FOURCC contains a space (such as
-Apple's "rle " codec).
-The "flags" keywords identifies any additional abilities of this
-codec. Currently, seekable is the only supported flag.
-Adding FFmpeg Codecs
-example codec:
-videocodec ffmdec
- info "FFmpeg Sony PlayStation MDEC (Motion DECoder)"
- status working
- fourcc MDEC ; internal MPlayer FourCC
- driver ffmpeg
- dll mdec
- out YV12
-The "videocodec" name should start with ff to differentiate it from other
-libraries or binary codecs.
-The "dll" name comes from the codec source file or the libavcodec/allcodecs.c
-The "out" colorspace can be found in the codec source file in the PIX_FMT
-struct. Note that some codecs may have several pix_fmt structs.
-The pix_fmt can be converted to the codecs.conf "out" format by reading
-the fmt-conversion.c file.
-If there are BE and LE versions of a pix_fmt, ignore them and use the short
-native format instead. e.g. 422P16_LE becomes out 422P16. also to note that
-underscores cause parse errors, so 422P16_LE becomes out 422P16LE.
-Sometimes the lavf demuxer will not pass on a fourcc (mostly video game
-formats or other containers that do not support isom/riff tags). You will have
-to make one based on the codec_id listed in the codec source file.
-Note that it is a good idea to mark any fourcc you create as
-' ; internal MPlayer FourCC'. In case another codec uses that fourcc,
-you can easily change the internal one. Also this will stop other projects
-from thinking of the internal tag as a real fourcc found in the wild.
-Some audio codecs require a parser, you can see which ones do
-by reading the parsers section in libavcodec/allcodecs.c.
