* video: introduce failure path for image allocationswm42014-06-171-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, failure to allocate image data resulted in a crash (i.e. abort() was called). This was intentional, because it's pretty silly to degrade playback, and in almost all situations, the OOM will probably kill you anyway. (And then there's the standard Linux overcommit behavior, which also will kill you at some point.) But I changed my opinion, so here we go. This change does not affect _all_ memory allocations, just image data. Now in most failure cases, the output will just be skipped. For video filters, this coincidentally means that failure is treated as EOF (because the playback core assumes EOF if nothing comes out of the video filter chain). In other situations, output might be in some way degraded, like skipping frames, not scaling OSD, and such.

* video: synchronize mpv rgb pixel format names with ffmpeg nameswm42014-06-141-1/+1
| | | | | | | | | | | This affects packed RGB formats up to 16 bits per pixel. The old mplayer names used LSB-to-MSB order, while FFmpeg (and some other libraries) use MSB-to-LSB. Nothing should change with this commit, i.e. no bit order or endian bugs should be added or fixed. In some cases, the name stays the same, even though the byte order changes, e.g. RGB8->BGR8 and BGR8->RGB8, and this affects the user-visible names too; this might cause confusion.
* Add more constwm42014-06-111-7/+7
| | | | | | | 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.
* video: remove redundant mp_image display_w/_h memberswm42014-04-291-2/+2
| | | | | | | | | | | | | | | | | Commit 5e4e248 added a mp_image_params field to mp_image, and moved many parameters to that struct. display_w/h was left redundant with mp_image_params.d_w/d_h. These fields were supposed to be always in sync, but it seems some code forgot to do this correctly, such as vf_fix_img_params() or mp_image_copy_attributes(). This led to the problem in github issue #756, because display_w/_h could become incorrect. It turns out that most code didn't use the old fields anyway. Just remove them. Note that mp_image_params.d_w/d_h are supposed to be always valid, so the additional checks for 0 shouldn't be needed. Remove these checks as well. Fixes #756.

* video/fmt-conversion.c: remove unknown pixel format messageswm42013-12-211-0/+5
| | | | | | | | | | | This removes the messages printed on unknown pixel format messages. Passing a mp_log to them would be too messy. Actually, this is a good change, because in the past we often had trouble with these messages printed too often (causing terminal spam etc.), and printing warnings or error messages on the caller sides is much cleaner. vd_lavc.c had a change earlier to print an error message if a decoder outputs an unsupported pixel format.
* image_writer: mp_msg conversionswm42013-12-211-10/+8
| | | | Adds an awkward mp_log argument for error messages.
* Move options/config related files from mpvcore/ to options/wm42013-12-171-1/+1
| | | | | | | | | 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.
* configure: uniform the defines to #define HAVE_xxx (0|1)Stefano Pigozzi2013-11-031-3/+3
| | | | | | | | | | | | | | | | | | | | | The configure followed 5 different convetions of defines because the next guy always wanted to introduce a new better way to uniform it[1]. For an hypothetic feature 'hurr' you could have had: * #define HAVE_HURR 1 / #undef HAVE_DURR * #define HAVE_HURR / #undef HAVE_DURR * #define CONFIG_HURR 1 / #undef CONFIG_DURR * #define HAVE_HURR 1 / #define HAVE_DURR 0 * #define CONFIG_HURR 1 / #define CONFIG_DURR 0 All is now uniform and uses: * #define HAVE_HURR 1 * #define HAVE_DURR 0 We like definining to 0 as opposed to `undef` bcause it can help spot typos and is very helpful when doing big reorganizations in the code.

* core: move contents to mpvcore (2/2)Stefano Pigozzi2013-08-061-1/+1
| | | | Followup commit. Fixes all the files references.
* sws_utils: make hq swscale flags available with mp_sws_hq_flagswm42013-07-181-5/+1
| | | | No need to duplicate this on the call-site.
* image_writer: Add PNG filter option (default "mixed")Martin Herkt2013-06-151-1/+5
| | | | | | The use of filters prior to PNG compression can greatly improve compression ratio, with "mixed" (ImageMagick calls it "adaptive") typically achieving the best results.
* Prefix CODEC_ID_ with AV_wm42013-03-131-6/+6
| | | | | | | | | The old names have been deprecated a while ago, but were needed for supporting older ffmpeg/libav versions. The deprecated identifiers have been removed from recent Libav and FFmpeg git. This change breaks compatibility with Libav 0.8.x and equivalent FFmpeg releases.
* image_writer: switch to avcodec_encode_video2()wm42013-03-131-14/+11
| | | | | | | | avcodec_encode_video() was deprecated, and was finally removed from Libav and FFmpeg git. This change breaks compatibility with Libav 0.8.x. Thank the Libav developers, not me.
* m_option: don't define OPT_BASE_STRUCT by defaultwm42013-03-011-1/+0
| | | | | | | | | | | OPT_BASE_STRUCT defines which struct the OPT_ macros (like OPT_INT etc.) reference implicitly, since these macros take struct member names but no struct type. Normally, only cfg-mplayer.h should need this, and other places shouldn't be bothered with having to #undef it. (Some files, like demux_lavf.c, still store their options in MPOpts. In the long term, this should be removed, and handled like e.g. with VO suboptions instead.)
* cleanup: replace OPT_FLAG_ON and OPT_MAKE_FLAGS with OPT_FLAGwm42013-02-091-2/+2
| | | | | | | | | | OPT_MAKE_FLAGS() used to emit two options (one with "no" prefixed), but that has been long removed by special casing flag options in the option parser. OPT_FLAG_ON() used to imply that there's no "no-" prefixed option, but this hasn't been the case for a while either. (Conceptually, it has been replaced by OPT_FLAG_STORE().) Remove OPT_FLAG_OFF, which was unused.
* video: decouple internal pixel formats from FourCCswm42013-01-131-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* video: cleanup: replace old mp_image function nameswm42013-01-131-2/+2
| | | | | mp_image_alloc() also changes argument order compared to alloc_mpi(). The format now comes first, then width/height.
* video: cleanup: move and rename vf_mpi_clear and vf_clone_attributeswm42013-01-131-3/+1
| | | | | | | | These functions weren't specific to video filters and were misplaced in vf.c. Move them to mp_image.c. Fix the big endian test in vf_mpi_clear/mp_image_clear, which has been messed up in 74df1d.
* video: fix bogus uses of mp_image.w/widthwm42012-11-211-10/+7
| | | | | | | | | | | | | | | | | mp_image has this confusing distinction between the w/h and width/height fields. w/h are the actual width and height, while width/height have a very special meaning inside the video filter code: it's the actually allocated width, which is also used for stride padding. Screenshot related code abused the w/h fields to store the aspect corrected size. Some code confused the role of w/h and width/height. Fix these issues. For aspect corrected size, display_w/h are used, while width/height should never be used outside vf.c internals and related code. This also fixes an actual bug when taking screenshots of anamorphic video with vf_screenshot, as well as using vo_image with such videos.
* Add missing compat/libav.h includeswm42012-11-121-0/+2
| | | | For avcodec_free_frame().
* Rename directories, move files (step 2 of 2)wm42012-11-121-8/+7
| | | | | | | | | | | | Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)
* Rename directories, move files (step 1 of 2) (does not compile)wm42012-11-121-0/+327
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.
