* vf: minor simplificationwm42014-11-121-2/+0
| | | | | | | | Remove the extra vf_chain.output field - there's absolutely no need for it, because there is always a last filter which will buffer the output. For some reason, vf_chain.last was never set, which we now need to fix too.
* video/filter: allow better dataflowwm42014-09-181-0/+9
| | | | | | | | | Consider a filter which turns 1 frame into 2 frames (such as an deinterlacer). Until now, we forced filters to produce all output frames at once. This was done for simplicity. Change the filter API such that a filter can produce frames incrementally.
* video: introduce failure path for image allocationswm42014-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* options: remove global variables for swscale options; rename themwm42014-06-111-0/+1
| | | | | | Additionally to removing the global variables, this makes the options more uniform. --ssf-... becomes --sws-..., and --sws becomes --sws- scaler. For --sws-scaler, use choices instead of magic integer values.
* vf: print for which filter initialization failedwm42014-05-041-1/+2

* video: removed unused stuffwm42014-05-021-1/+0
|
* video: handle colorspace and aspect overrides separatelywm42014-05-021-1/+3
| | | | | Now the video filter code handles these explicitly, which should increase robustness (or at least find bugs earlier).
* vf: add alternate functions for retrieving filter outputwm42014-05-021-0/+4
| | | | | | | These replace vf_read_output_frame(), although we still emulate that function. This change is preparation for another commit (and this is basically just to reduce the diff and signal/noise ratio in that commit).
* vf: expose input parameters; clear parameters on failurewm42014-05-021-0/+1
| | | | Preparation (and simplification) for following commits.
* video: don't drop last frame when deinterlacing with yadifwm42014-04-281-1/+4
| | | | | | | | | | | | | | | | | | Or in other words, add support for properly draining remaining frames from video filters. vf_yadif is buffering at least one frame, and the buffered frame was not retrieved on EOF. For most filters, ignore this for now, and just adjust them to the changed semantics of filter_ext. But for vf_lavfi (used by vf_yadif), real support is implemented. libavfilter handles this simply by passing a NULL frame to av_buffersrc_add_frame(), so we just have to make mp_to_av() handle NULL arguments. In load_next_vo_frame(), we first try to output a frame buffered in the VO, then the filter, and then (if EOF is reached and there's still no new frame) the VO again, with draining enabled. I guess this was implemented slightly incorrectly before, because the filter chain still could have had remaining output frames.
* vf: remove autoinserted filters on reconfigwm42014-04-211-0/+1
| | | | | | | When using rotation with hw decoding, and the VO does not support rotation, vf_rotate is attempted to be inserted. This will go wrong, and after that it can't recover because a vf_scale filter was autoinserted. Just removing all autoinserted filters before reconfig fixes this.

* video: move VO reinit from filter chain to playerwm42013-12-101-2/+4
| | | | | | | | | This gets rid of the vf_vo pseudo-filter. It ends the idea of MPlayer's architecture that the VO is just a (terminating) video filter. It didn't really work for us with respect to video timing (the "end" of the video chain isn't really made for video timing, and making it do so would be awkward), and now we're removing it entirely. We will be able to fix some things, such as properly draining video on reconfiguration.
* vf: redo conversion filter insertion/format negotiationwm42013-12-071-7/+11
| | | | | | | | | | | | | | | | | Remove the inconsistent, duplicated, and insufficient scale filter insertion code, and do it in one place instead. This also compensates for the earlier removal of vf_match_csp() (which was in fact duplicated code). The algorithm to determine where to insert a filter etc. is probably the same, though it also comes with some changes that should make debugging easier when trying to figure out why a chain is failing to configure. Add an "in" pseudo filter, which makes insertion of conversion filters easier. Also change the vf->reconfig signature. At a later point, I'll probably change format negotiation such that the generic filter code will choose the output format, so having separate in and out params will be useful.
* video/filter: make vf->control non-recursivewm42013-12-071-1/+0
| | | | | | Reason: I never liked it being recursive. Generally, this seems to cause more problems than trouble, and is less flexible for access outside of the chain.
* vf: remove flags from filter format statuswm42013-12-071-9/+2
| | | | | | | | I don't think we need these flags anymore. Simplify the code and get rid of the vf_format struct. There still is the vf_format.configured field, but this can be replaced by checking for a valid image format.
* video: create a separate context for video filter chainwm42013-12-071-22/+30
| | | | | | This adds vf_chain, which unlike vf_instance refers to the filter chain as a whole. This makes the filter API less awkward, and will allow handling format negotiation better.
* video/filter: remove vf_match_csp()wm42013-12-071-3/+0
| | | | | | | | | This function improves automatic filter insertion, but this really should be done by the generic filter code. Remove vf_match_csp() and all code using it as preparation for that. This commit temporarily makes handling of filter insertion worse for now, but it will be fixed with the following commits.
* vf: remove unused functionwm42013-12-071-1/+0

* vf: declare config() as legacywm42013-12-051-5/+5

* vf: move norm_qscale() to the only filter which uses itwm42013-12-051-15/+0
|
* video/filter: remove legacy option handling hackswm42013-12-041-1/+1
| | | | | | | | | All filters now either use the generic option parser, or don't have options. This finally finishes a transition started in 2003 (see git commit 33b62af94760186c). Why are MPlayer devs so monumentally lazy? Sorry, but this takes the cake. You had 10 years.
* vf_vo: don't abuse option strings to set VOwm42013-12-041-0/+1
| | | | Whoever thought this was a good idea should be punched.
* vf: remove unneeded fieldwm42013-12-041-1/+0
| | | | | This was once required for padding, because many filters didn't use designated initializers, and initialized a removed field with NULL.
* options: implement --pphelp differentlywm42013-11-231-0/+1
| | | | Make it work via --vf=pp:help instead.
* video: remove vf_pp auto-insertionwm42013-11-231-2/+0
| | | | | | | | | | This drops the --pp option, which was probably broken for a while. The option automatically inserted the "pp" filter. The value passed to it was ignored (which is probably broken, it always selected maximal quality). Inserting this filter can be done simply with --vf=pp, so this is not needed anymore.
* video/filter: remove useless vf_info fieldswm42013-10-231-4/+2
| | | | | This time I didn't bother to move the contents of the author field to the file headers. "git log" is your friend.
* cosmetics: replace "CTRL" defines by enumswm42013-10-021-13/+15
| | | | Because why not.
* vd: move aspect calculation to a functionwm42013-09-261-0/+1
| | | | | | | | This function would probably be useful in other places too. I'm not sure why vd.c doesn't apply the aspect if it changes size by less than 4 pixels. Maybe it's supposed to avoid ugly results with bad scalers if the difference is too small to be noticed normally.
* vaapi: add vf_vavpp and use it for deinterlacingxylosper2013-09-251-0/+1
| | | | | | | | Merged from pull request #246 by xylosper. Minor cosmetic changes, some adjustments (compatibility with older libva versions), and manpage additions by wm4. Signed-off-by: wm4 <wm4@nowhere>
* video: handle video output levels with mp_image_paramswm42013-08-241-2/+0
| | | | | | | | | | | | Until now, video output levels (obscure feature, like using TV screens that require RGB output in limited range, similar to YUY) still required handling of VOCTRL_SET_YUV_COLORSPACE. Simplify this, and use the new mp_image_params code. This gets rid of some code. VOCTRL_SET_YUV_COLORSPACE is not needed at all anymore in VOs that use the reconfig callback. The result of VOCTRL_GET_YUV_COLORSPACE is now used only used for the colormatrix related properties (basically, for display on OSD). For other VOs, VOCTRL_SET_YUV_COLORSPACE will be sent only once after config instead of twice.
* core: move contents to mpvcore (2/2)Stefano Pigozzi2013-08-061-1/+1
| | | | Followup commit. Fixes all the files references.
* vdpau: split off decoder parts, use "new" libavcodec vdpau hwaccel APIwm42013-07-281-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the decoder parts from vo_vdpau.c to a new file vdpau_old.c. This file is named so because because it's written against the "old" libavcodec vdpau pseudo-decoder (e.g. "h264_vdpau"). Add support for the "new" libavcodec vdpau support. This was recently added and replaces the "old" vdpau parts. (In fact, Libav is about to deprecate and remove the "old" API without deprecation grace period, so we have to support it now. Moreover, there will probably be no Libav release which supports both, so the transition is even less smooth than we could hope, and we have to support both the old and new API.) Whether the old or new API is used is checked by a configure test: if the new API is found, it is used, otherwise the old API is assumed. Some details might be handled differently. Especially display preemption is a bit problematic with the "new" libavcodec vdpau support: it wants to keep a pointer to a specific vdpau API function (which can be driver specific, because preemption might switch drivers). Also, surface IDs are now directly stored in AVFrames (and mp_images), so they can't be forced to VDP_INVALID_HANDLE on preemption. (This changes even with older libavcodec versions, because mp_image always uses the newer representation to make vo_vdpau.c simpler.) Decoder initialization in the new code tries to deal with codec profiles, while the old code always uses the highest profile per codec. Surface allocation changes. Since the decoder won't call config() in vo_vdpau.c on video size change anymore, we allow allocating surfaces of arbitrary size instead of locking it to what the VO was configured. The non-hwdec code also has slightly different allocation behavior now. Enabling the old vdpau special decoders via e.g. --vd=lavc:h264_vdpau doesn't work anymore (a warning suggesting the --hwdec option is printed instead).
* vf: fix unintended overwriting of image infowm42013-07-281-2/+2
| | | | | | The symptom was that "-vf scale,format=rgba" broke the vsfilter colorspace hack in sd_ass. vf->reconfig is allowed to overwrite its input parameter for convenience (maybe that was a bad idea).
* options: use m_config for options instead of m_structwm42013-07-211-2/+4
| | | | | | | | | | | | | | | | | | For some reason, both m_config and m_struct are somewhat similar, except that m_config is much more powerful. m_config is used for VOs and some other things, so to unify them. We plan to kick out m_struct and use m_config for everything. (Unfortunately, m_config is also a bit more bloated, so this commit isn't all that great, but it will allow to reduce the option parser mess somewhat.) This commit also switches all video filters to use the option macros. One reason is that m_struct and m_config, even though they both use m_option, store the offsets of the option fields differently (sigh...), meaning the options defined for either are incompatible. It's easier to switch everything in one go. This commit will allow using the -vf option parser for other things, like VOs and AOs.
* vf: remove unnecessary indirectionwm42013-07-211-6/+0
|
* vf: add vf_control wrapperwm42013-07-151-0/+1
| | | | | Slightly cleaner, although rather redundant. But still, why wasn't this added 10 years ago?
* video: add a new method to configure filters and VOswm42013-06-281-6/+15
| | | | | | | | | | | | | | | | | | The filter chain and the video ouputs have config() functions. They are strictly limited to transfering the video size and format. Other parameters (like color levels) have to be transferred separately. Improve upon this by introducing a separate set of reconfig() functions, which use mp_image_params to carry format parameters. This struct contains all image format related parameters from config(), plus additional parameters such as colorspace. Change vf_rotate to use it, as well as vo_opengl. vf_rotate is just an example/test case, but vo_opengl will need it later. The intention is also to get rid of VOCTRL_SET_YUV_COLORSPACE. This information is now handed to the VOs via reconfig(). The getter, VOCTRL_GET_YUV_COLORSPACE, will still be needed though.
* m_option, vf: add label supportwm42013-05-231-0/+4
| | | | | | | | | | | | | | | | | Can be used to refer to filters by name. Intended to be used when the filter chain is changed at runtime. A label can be assigned to a filter by prefixing it with '@name:', where 'name' is an user-chosen identifier. For example, a filter added with '-vf-add @label1:gradfun=123' can be removed with '-vf-del @label1'. If a filter with an already existing label is added, the existing filter is replaced with the new filter (this happens for both -vf-add and -vf-pre). If a filter is replaced, the new filter takes the position of the old filter, instead of being appended/prepended to the filter chain as usual. For -vf-toggle, labels are compared if at least one of the filters has a label; otherwise they are compared by filter name and arguments (like before). This means two filters are never considered equal if one has a label and the other one does not.
* core: simplify OSD capability handling, remove VFCAP_OSDwm42013-03-011-2/+0
| | | | | | | | | | | | | | | | | | | 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.)
* core: redo how codecs are mapped, remove codecs.confwm42013-02-101-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 VOwm42013-01-231-2/+2
| | | | | | | | | 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/+2
| | | | | | | | | | | | | | | | 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 modewm42013-01-141-1/+2
| | | | | Somewhat useful to see where filters are auto-inserted and which formats they take.
* vf: add vf_rescale_dsize()wm42013-01-131-0/+3
| | | | | | | | 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_attributeswm42013-01-131-3/+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.
* vf_screenshot: simplifywm42013-01-131-7/+1
| | | | | | | | | | Instead of using a callback to "capture" the image next time the filter function is called, do it the other way around: on every filter invocation, create a reference to the image, and return it if a screenshot is requested. This also fixes the 1-frame delay when taking screenshots with the filter. This also allows simplifying screenshot.c.
* video/filter: change filter API, use refcounting, remove filter DRwm42013-01-131-29/+28
| | | | | | | | | | | | | | | | | | | | 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 pathwm42013-01-131-0/+1
| | | | | | vdpau hardware decoding used the DR (direct rendering) path to le
