* video: remove things related to old DR codewm42013-01-131-6/+1
| | | | | | | | | | | | | | | Remove mp_image.width/height. The w/h members are the ones to use. width/height were used internally by vf_get_image(), and sometimes for other purposes. Remove some image flags, most of which are now useless or completely unused. This includes VFCAP_ACCEPT_STRIDE: the vf_expand insertion in vf.c does nothing. Remove some other unused mp_image fields. Some rather messy changes in vo_opengl[_old] to get rid of legacy mp_image flags and fields. This is left from when vo_gl supported DR.
* video/filter: change filter API, use refcounting, remove filter DRwm42013-01-131-10/+2
| | | | | | | | | | | | | | | | | | | | 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 Note that another form of DR used for in-place filters has been replaced by simpler logic.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.
* video: make vdpau hardware decoding not use DR code pathwm42013-01-131-11/+2
| | | | | | vdpau hardware decoding used the DR (direct rendering) path to let the decoder query a surface from the VO. Special-case the HW decoding path instead, to make it separate from DR.
* video: remove slice based filtering and video outputwm42013-01-131-21/+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.
* video: make vdpau hardware decoding not use slices code pathwm42013-01-131-0/+2
| | | | | | | | | | | | | | For some reason, libavcodec abuses the slices rendering code path for hardware decoding: in that case, the only purpose of the draw callback is to pass a vdpau video surface object to video output. (It is unclear to me why this had to use the slices code, instead of just returning an AVFrame with the required vdpau state.) Make this code separate within mpv, so that the internal slices code path is not used for hardware decoding. Pass the vdpau state with VOCTRL_HWDEC_DECODER_RENDER instead. Remove the mencoder specific VOCTRLs.
* video/out: replace VOCTRL_QUERY_FORMAT with vo_driver.query_formatwm42013-01-131-1/+1
|
* video/out: make draw_image mandatory, remove VOCTRL_DRAW_IMAGEwm42013-01-131-12/+1
| | | | | | | | | | | | | Remove VOCTRL_DRAW_IMAGE and always set vo_driver.draw_image in VOs. Make draw_image mandatory: change some VOs (like vo_x11) to support it, and remove the image-to-slices fallback in vf_vo. Remove vo_driver.is_new. This member indicated whether draw_image is supported unconditionally, which is now always the case. draw_image_pts is a hack until the video filter chain is changed to include the PTS as field in mp_image. Then vo_vdpau and vo_lavc will be changed to use draw_image.
* options, vo_x11: remove -zoom option, make it defaultwm42012-11-161-2/+1
| | | | | | | | | | | | | | 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)wm42012-11-121-4/+4
| | | | | | | | | | | | 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/+202
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.
