core: add a playlist demuxer Modeled after the old playlist_parser.c, but actually new code, and it works a bit differently. Demuxers (and sometimes streams) are the component that should be used to open files and to determine the file format. This was already done for subtitles, but playlists still use a separate code path.

player: allow playing directories If a directory is encountered, replace it with its contents in the internal playlist. This is messed into demux_playlist.c, because why not. STREAMTYPE_DIR could be avoided by unconditonally trying opendir() in demux_playlist.c, but it seems nicer not to do weird things like calling it on real files. This does not work on Windows, because msvcrt is retarded.

Move options/config related files from mpvcore/ to options/ Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok.

demux_playlist: redirect ASF streaming to mmsh:// I'm not sure if this could be done in libavformat instead. Probably not, because libavformat doesn't seem to have any mechanism for trying one protocol and reverting (or redirecting) to another one if needed. This commit is sort of a hack too, because it redirects the URL by pretending the http:// link is a playlist containing the mmsh:// link. The list of mime types is borrowed from MPlayer (which has completely different code to handle this).

(so that when <embed>ing videos quicktime would be forced.) These mov files may contain several "Text Hacks". One of these is RTSPtext. The suggested/allowed format (as regex) is like: RTSPtext[ \r]RTSP://url See also p.51 of: https://developer.apple.com/library/mac/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML.pdf In reality there are also files like (e.g. zdfmediathek.de): RTSPtext\nrtsp://url\n\n Lets handle these files as a playlist with one element.

Each "File" entry is followed by a number that is supposed to be the entry number, and "File1" is first.

demux_playlist: redirect ASF streaming to mmsh:// I'm not sure if this could be done in libavformat instead. Probably not, because libavformat doesn't seem to have any mechanism for trying one protocol and reverting (or redirecting) to another one if needed. This commit is sort of a hack too, because it redirects the URL by pretending the http:// link is a playlist containing the mmsh:// link. The list of mime types is borrowed from MPlayer (which has completely different code to handle this).

core: add a playlist demuxer Modeled after the old playlist_parser.c, but actually new code, and it works a bit differently. Demuxers (and sometimes streams) are the component that should be used to open files and to determine the file format. This was already done for subtitles, but playlists still use a separate code path.

Add more const While I'm not very fond of "const", it's important for declarations (it decides whether a symbol is emitted in a read-only or read/write section). Fix all these cases, so we have writeable global data only when we really need.

demux_playlist: port ini reference playlist parser Port it from playlist_parser.c to demux_playlist.c. Also, change the m3u parser to drop whitespace from the trailing part of the line (will make it work properly with windows line endings). (I hoped that this would make MMS URIs with http instead of mmsh prefixes work, but it doesn't. Instead, it leads to a playlist loop. So solving this issue would require a change in ffmpeg, probably.)

demux_playlist: add mov RTSPtext tag parser The quicktime html scripting guide suggests to wrap urls not necesarly associated with quicktime in a .mov file. (so that when <embed>ing videos quicktime would be forced.) These mov files may contain several "Text Hacks". One of these is RTSPtext. The suggested/allowed format (as regex) is like: RTSPtext[ \r]RTSP://url See also p.51 of: https://developer.apple.com/library/mac/documentation/QuickTime/Conceptual/QTScripting_HTML/QTScripting_HTML.pdf In reality there are also files like (e.g. zdfmediathek.de): RTSPtext\nrtsp://url\n\n Lets handle these files as a playlist with one element.

demux_playlist: detect headerless m3u files by extension m3u files are normally just text files with a list of filenames. Nothing actually mandates that there is a header. Until now, we've rejected such files, because there's absolutely no way to detect them. If nothing else claims the file, the extension is ".m3u", and if the contents of the file look like text, then load it as m3u playlist. The text heuristic is pretty cheap, but at least it should prevent trying to load binary data as playlist. (Which would "work", but result in a catastrophic user experience.) Due to the text heuristic, UTF-16/32 files will be rejected (unless they have a header), but I don't care.
