* core: simplify OSD capability handling, remove VFCAP_OSDwm42013-03-011-4/+1
| | | | | | | | | | | | | | | | | | | VFCAP_OSD was used to determine at runtime whether the VO supports OSD rendering. This was mostly unused. vo_direct3d had an option to disable OSD (was supposed to allow to force auto-insertion of vf_ass, but we removed that anyway). vo_opengl_old could disable OSD rendering when a very old OpenGL version was detected, and had an option to explicitly disable it as well. Remove VFCAP_OSD from everything (and some associated logic). Now the vo_driver.draw_osd callback can be set to NULL to indicate missing OSD support (important so that vo_null etc. don't single-step on OSD redraw), and if OSD support depends on runtime support, the VO's draw_osd should just do nothing if OSD is not available. Also, do not access vo->want_redraw directly. Change the want_redraw reset logic for this purpose, too. (Probably unneeded, vo_flip_page resets it already.)
* screenshot: minor simplification, prefer VF over VOwm42013-01-301-2/+0
| | | | | | | | | | | | | Remove screenshot_force and associated logic. Always try to use the screenshot video filter before trying taking screenshots with the VO, which means that --vf=screenshot now takes the role of --vf=screenshot_force. (To make this clear, not adding a video filter is still the recommended way to take screenshots; we just change how VF screenshots are forced.) Preferring VO over VF and having --vf=screenshot_force used to make sense when not all VOs supported screenshots, and some VOs had somewhat broken screenshots (like vo_xv taking screenshots with OSD in it). But all these issues are fixed now, so just get rid of the cruft.
* video: move handling of -x/-y/-xy options to VOwm42013-01-231-9/+5
| | | | | | | | | 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: reset filters on seekwm42013-01-201-0/+7
| | | | | | | | | | | | | | | | Drop queued frames on seek. Reset the internal state of some filters that seem to need it as well: at least vf_divtc still produced some frames using the previous PTS. This fixes weird behavior with some filters on seeking. In particular, this could lead to A/V desync or apparent lockups due to the PTS of filtered frames being too far away from audio PTS. This commit does only the minimally required work to fix these PTS related issues. Some filters have state dependent on previously filtered frames, and these are not automatically reset with this commit (even vf_divtc and vf_softpulldown reset the PTS info only). Filters that actually require a full reset can implement VFCTRL_SEEK_RESET.
* video: print filter chain in verbose modewm42013-01-141-2/+32
| | | | | Somewhat useful to see where filters are auto-inserted and which formats they take.
* vf: add vf_rescale_dsize()wm42013-01-131-0/+15
| | | | | | | | Needed because mplayer* basically tracks DAR, which makes it harder for filters which want to keep the SAR. The contents of this function are duplicated in a few filters, and will be used instead of custom code as the filters are updated later.
* video: cleanup: move and rename vf_mpi_clear and vf_clone_attributeswm42013-01-131-73/+0
| | | | | | | | 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.
* mp_image: change how palette is handledwm42013-01-131-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | According to DOCS/OUTDATED-tech/colorspaces.txt, the following formats are supposed to be palettized: IMGFMT_BGR8 IMGFMT_RGB8, IMGFMT_BGR4_CHAR IMGFMT_RGB4_CHAR IMGFMT_BGR4 IMGFMT_RGB4 Of these, only BGR8 and RGB8 are actually treated as palettized in some way. ffmpeg has only one palettized format (AV_PIX_FMT_PAL8), and IMGFMT_BGR8 was inconsistently mapped to packed non-palettized RGB formats too (AV_PIX_FMT_BGR8). Moreover, vf_scale.c contained messy hacks to generate a palette when AV_PIX_FMT_BGR8 is output. (libswscale does not support AV_PIX_FMT_PAL8 output in the first place.) Get rid of all of this, and introduce IMGFMT_PAL8, which directly maps to AV_PIX_FMT_PAL8. Remove the palette creation code from vf_scale.c. IMGFMT_BGR8 maps to AV_PIX_FMT_RGB8 (don't ask me why it's swapped), without any palette use. Enabling it in vo_x11 or using it as vf_scale input seems to give correct results.
* video: remove things related to old DR codewm42013-01-131-19/+11
| | | | | | | | | | | | | | | 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 DRwm42013-01-131-243/+91
| | | | | | | | | | | | | | | | | | | | 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: remove slice based filtering and video outputwm42013-01-131-42/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | 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/filter: rename vf_eq2 to vf_eqwm42012-11-161-2/+2
| | | | | vf_eq was deleted earlier, which makes the name vf_eq2 even more awkward.
* Rename directories, move files (step 2 of 2)wm42012-11-121-6/+6
| | | | | | | | | | | | 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/+830
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.
