From d4bdd0473d6f43132257c9fb3848d829755167a3 Mon Sep 17 00:00:00 2001 From: wm4 Date: Mon, 5 Nov 2012 17:02:04 +0100 Subject: Rename directories, move files (step 1 of 2) (does not compile) Tis drops the silly lib prefixes, and attempts to organize the tree in a more logical way. Make the top-level directory less cluttered as well. Renames the following directories: libaf -> audio/filter libao2 -> audio/out libvo -> video/out libmpdemux -> demux Split libmpcodecs: vf* -> video/filter vd*, dec_video.* -> video/decode mp_image*, img_format*, ... -> video/ ad*, dec_audio.* -> audio/decode libaf/format.* is moved to audio/ - this is similar to how mp_image.* is located in video/. Move most top-level .c/.h files to core. (talloc.c/.h is left on top- level, because it's external.) Park some of the more annoying files in compat/. Some of these are relicts from the time mplayer used ffmpeg internals. sub/ is not split, because it's too much of a mess (subtitle code is mixed with OSD display and rendering). Maybe the organization of core is not ideal: it mixes playback core (like mplayer.c) and utility helpers (like bstr.c/h). Should the need arise, the playback core will be moved somewhere else, while core contains all helper and common code. --- demux/asf.h | 251 ++++ demux/asfguid.h | 89 ++ demux/asfheader.c | 717 ++++++++++ demux/asfheader.h | 28 + demux/aviheader.c | 674 +++++++++ demux/aviheader.h | 382 ++++++ demux/aviprint.c | 197 +++ demux/aviprint.h | 35 + demux/demux.c | 1435 ++++++++++++++++++++ demux/demux.h | 414 ++++++ demux/demux_asf.c | 697 ++++++++++ demux/demux_avi.c | 909 +++++++++++++ demux/demux_cue.c | 65 + demux/demux_edl.c | 58 + demux/demux_gif.c | 338 +++++ demux/demux_lavf.c | 1092 +++++++++++++++ demux/demux_mf.c | 226 ++++ demux/demux_mkv.c | 2558 ++++++++++++++++++++++++++++++++++ demux/demux_mng.c | 623 +++++++++ demux/demux_mpg.c | 1248 +++++++++++++++++ demux/demux_packet.h | 40 + demux/demux_rawaudio.c | 127 ++ demux/demux_rawvideo.c | 172 +++ demux/demux_ts.c | 3537 ++++++++++++++++++++++++++++++++++++++++++++++++ demux/demux_ts.h | 24 + demux/ebml.c | 670 +++++++++ demux/ebml.h | 107 ++ demux/extension.c | 104 ++ demux/matroska.h | 86 ++ demux/mf.c | 171 +++ demux/mf.h | 36 + demux/mp3_hdr.c | 144 ++ demux/mp3_hdr.h | 36 + demux/mp_taglists.c | 158 +++ demux/mp_taglists.h | 28 + demux/mpeg_hdr.c | 539 ++++++++ demux/mpeg_hdr.h | 55 + demux/ms_hdr.h | 114 ++ demux/parse_es.c | 158 +++ demux/parse_es.h | 45 + demux/stheader.h | 195 +++ demux/video.c | 622 +++++++++ 42 files changed, 19204 insertions(+) create mode 100644 demux/asf.h create mode 100644 demux/asfguid.h create mode 100644 demux/asfheader.c create mode 100644 demux/asfheader.h create mode 100644 demux/aviheader.c create mode 100644 demux/aviheader.h create mode 100644 demux/aviprint.c create mode 100644 demux/aviprint.h create mode 100644 demux/demux.c create mode 100644 demux/demux.h create mode 100644 demux/demux_asf.c create mode 100644 demux/demux_avi.c create mode 100644 demux/demux_cue.c create mode 100644 demux/demux_edl.c create mode 100644 demux/demux_gif.c create mode 100644 demux/demux_lavf.c create mode 100644 demux/demux_mf.c create mode 100644 demux/demux_mkv.c create mode 100644 demux/demux_mng.c create mode 100644 demux/demux_mpg.c create mode 100644 demux/demux_packet.h create mode 100644 demux/demux_rawaudio.c create mode 100644 demux/demux_rawvideo.c create mode 100644 demux/demux_ts.c create mode 100644 demux/demux_ts.h create mode 100644 demux/ebml.c create mode 100644 demux/ebml.h create mode 100644 demux/extension.c create mode 100644 demux/matroska.h create mode 100644 demux/mf.c create mode 100644 demux/mf.h create mode 100644 demux/mp3_hdr.c create mode 100644 demux/mp3_hdr.h create mode 100644 demux/mp_taglists.c create mode 100644 demux/mp_taglists.h create mode 100644 demux/mpeg_hdr.c create mode 100644 demux/mpeg_hdr.h create mode 100644 demux/ms_hdr.h create mode 100644 demux/parse_es.c create mode 100644 demux/parse_es.h create mode 100644 demux/stheader.h create mode 100644 demux/video.c (limited to 'demux') diff --git a/demux/asf.h b/demux/asf.h new file mode 100644 index 0000000000..2886a4d752 --- /dev/null +++ b/demux/asf.h @@ -0,0 +1,251 @@ +/* + * This file is part of MPlayer. + * + * MPlayer is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * MPlayer is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
