* vo: remove and cleanup globalsAlexander Preisinger2013-03-041-10/+10
| | | | | | | | Removes almost every global variabel in vo.h and puts them in a special struct in MPOpts for video output related options. Also we completly remove the options/globals pts and refresh rate because they were unused.
* video/out: remove video mode switching (--vm)wm42013-02-261-3/+2
| | | | | | | | | | | | | | | | | | | | This allowed making the player switch the monitor video mode when creating the video window. This was a questionable feature, and with today's LCD screens certainly not useful anymore. Switching to a random video mode (going by video width/height) doesn't sound too useful either. I'm not sure about the win32 implementation, but the X part had several bugs. Even in mplayer-svn (where x11_common.c hasn't been receiving any larger changes for a long time), this code is buggy and doesn't do the right thing anyway. (And what the hell _did_ it do when using multiple physical monitors?) If you really want this, write a shell script that calls xrandr before and after calling mpv. vo_sdl still can do mode switching, because SDL has native support for it, and using it is trivial. Add a new sub-option for this.
* core: redo how codecs are mapped, remove codecs.confwm42013-02-101-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: move handling of -x/-y/-xy options to VOwm42013-01-231-51/+20
| | | | | | | | | Now the calculations of the final display size are done after the filter chain. This makes the difference between display aspect ratio and window size a bit more clear, especially in the -xy case. With an empty filter chain, the behavior of the options should be the same, except that they don't affect vo_image and vo_lavc anymore.
* video: print filter chain in verbose modewm42013-01-141-7/+8
| | | | | Somewhat useful to see where filters are auto-inserted and which formats they take.
* video/filter: change filter API, use refcounting, remove filter DRwm42013-01-131-3/+0
| | | | | | | | | | | | | | | | | | | | Change the entire filter API to use reference counted images instead of vf_get_image(). Remove filter "direct rendering". This was useful for vf_expand and (in rare cases) vf_sub: DR allowed these filters to pass a cropped image to the filters before them. Then, on filtering, the image was "uncropped", so that black bars could be added around the image without copying. This means that in some cases, vf_expand will be slower (-vf gradfun,expand for example). Note that another form of DR used for in-place filters has been replaced by simpler logic. Instead of trying to do DR, filters can check if the image is writeable (with mp_image_is_writeable()), and do true in-place if that's the case. This affects filters like vf_gradfun and vf_sub. Everything has to support strides now. If something doesn't, making a copy of the image data is required.
* vd_lavc: remove codec DRwm42013-01-131-10/+0
| | | | | | | | | | This was buggy and didn't even work in the simplest cases. It was disabled when multithreading was used, and always disabled for h264. A better alternative (reference counting) will be added later. Hardware decoding still uses the ffmpeg DR mechanism, but has been decoupled from mpv's DR in the previous commit.
* video: simplify decoder pixel format handlingwm42013-01-131-58/+25
| | | | | | | | | | | | | | | | | | | | Simplify the decoder pixel format handling by making it handle only the case vd_lavc needs: a video stream always decodes to a single pixel format. Remove the handling for multiple pixel formats, and remove the codecs.conf pixel format declarations that are left. Remove the handling of "ambiguous" pixel formats like YV12 vs. I420 (via VDCTRL_QUERY_FORMAT etc.). This is only a problem if the video chain supports I420, but not YV12, which doesn't seem to be the case anywhere, and in fact would not have any advantage. Make the "flip" flag a global per-codec flag, rather than a pixel format specific flag. (Some ffmpeg decoders still return a flipped image, so this has to be done manually.) Also fix handling of the flip operation: do not overwrite the global flip option, and make the --flip option invert the codec flip option rather than overriding it.
* video: remove slice based filtering and video outputwm42013-01-131-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | Slices allowed filtering or drawing video in horizontal bands or blocks. This allowed working on the video in smaller units. In theory, this could bring a performance win by lowering cache pressure, as you didn't have to keep the whole video frame in cache while filtering, only the slice. In practice, the slice code path was barely used for the following reasons: - Multithreaded decoding with ffmpeg didn't use slices. The ffmpeg slice callback was disabled, because it can be called from another thread, and the mplayer video chain is not thread-safe. - There was nothing that would turn "full" images into appropriate slices, so slices were rarely used. - Most filters didn't actually support slices. On the other hand, supporting slices lead to code duplication and more complex code in general. I made some experiments and didn't find any actual measurable performance improvements when using slices. Even ffmpeg removed slices based filtering from libavfilter in favor of simpler code. The most broken thing about the slices code path is that slices can't be queued, like it is done for images in vo.c.
* options, vo_x11: remove -zoom option, make it defaultwm42012-11-161-1/+0
| | | | | | | | | | | | | | The -zoom option enabled scaling with vo_x11. Remove the -zoom option, and make its behavior default. Since vo_x11 has to use libswscale for colorspace conversion anyway, which doesn't do actual extra scaling when vo_x11 is run in windowed mode, there should be no speed difference with this change. The code removed from vf_scale attempted to scale the video to d_width/ d_height, which matters for anamorphic video and the --xy option only. vo_x11 can handle these natively. The only case for which the removed vf_scale code could matter is encoding with vo_lavc, but since that didn't set VOFLAG_SWSCALE, nothing actually changes.
* Rename directories, move files (step 2 of 2)wm42012-11-121-8/+8
| | | | | | | | | | | | 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/+273
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.
