* video: remove slice based filtering and video outputwm42013-01-1313-301/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | 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 pathwm42013-01-132-3/+3
| | | | | | | | | | | | | | 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.
* configure: remove check for .align semanticswm42013-01-134-8/+8
| | | | | | | | | | | | | | | | | | | | | The check determined whether the argument for .align is in bytes, or log2(bytes). Apparently it's always in bytes for ELF i386 systems, and this check is used for x86 inline assembler only. Even if this assumption should be wrong, it likely won't cause much damage: the existing code uses it only in the form ".align 4", which means in the worst case it will try to align to 16 bytes, which doesn't cause any problems (unless the object file format does not support such a high alignment). Update the filters that used this. Quoting the GNU as manual: For other systems, including ppc, i386 using a.out format, arm and strongarm, it is the number of low-order zero bits the location counter must have after advancement. For example `.align 3' advances the location counter until it a multiple of 8. If the location counter is already a multiple of 8, no change is needed.
* vf_scale: prefer 420P10 -> YV12 instead of 444Pwm42012-12-281-0/+1
| | | | | | Strictly speaking, 444P is higher quality than YV12, but doing this is not very useful when playing 10 bit video with -vo opengl-old on a GPU that doesn't support 16 bit textures.
* vf_scale: support more pixel formatsRudolf Polzer2012-12-281-0/+4
| | | | | The RGBA, ARGB, BGRA, ABGR were previously not always supported, depending on system endianness.
* options: move -ass-bottom-margin/-ass-top-margin options to vf_subwm42012-12-121-10/+15
| | | | | These options might be useful sometimes, but they are not that important, and work with vf_sub only. Make them vf_sub sub-options.

* video: add support for 12 and 14 bit YUV pixel formatsStephen Hutchinson2012-12-031-0/+12
| | | | | | | | | | | | Based on a patch by qyot27. Add the missing parts in mp_get_chroma_shift(), which allow allocation of such images, and which make vo_opengl automatically accept the new formats. Change the IMGFMT_IS_YUVP16_LE/BE macros to properly report IMGFMT_444P14 as supported: this pixel format has the highest numerical bit width identifier (0x55), which is not covered by the mask ~0xfc. Remove 1 bit from the mask (makes it 0xf8) so that IMGFMT_IS_YUVP16(IMGFMT_444P14) is 1. This is slightly risky, as the organization of the image format IDs (actually FourCCs + mplayer internal IDs) is messy at best, but it should be ok.
* sws_utils: remove unused helperwm42012-11-241-1/+5
| | | | | | | | sws_getContextFromCmdLine_hq() was used by the screenshot code, which now uses mp_image_swscale(). Also move the mp_sws_set_colorspace() declaration from sws_utils.h to vf_scale.c.
* screenshot: add subs even with vf_screenshotwm42012-11-211-0/+1
| | | | | | | | | | | | | | Until now, screenshots with the video filter didn't add subs (unclear whether that was an oversight or feature). Fix this and make behavior when taking screenshots with vf_screenshot more consistent with VO screenshots. The change in vf_screenshot is needed, because add_subs() checks this flag to decide whether it's allowed to mutate the image. This commit has another user visible side effect. When taking a screenshot each frame (using the "each-frame" mode of the screenshot command), a normal screenshot command will stop the each-frame mode.
* video: fix bogus uses of mp_image.w/widthwm42012-11-211-2/+4
| | | | | | | | | | | | | | | | | 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.
* vf_softpulldown: fix possible regressionwm42012-11-201-1/+2
| | | | | | | | | The lines added with this commit were accidentally removed in commit a0d759, which was a pure cleanup commit merged from mplayer-svn. The difference between mplayer-svn and the mplayer2 base is that this filter has been made PTS aware in mplayer2. Also remove the redundant initialization of vf->priv->state.
* video/filter: rename vf_eq2 to vf_eqwm42012-11-162-4/+4
| | | | | vf_eq was deleted earlier, which makes the name vf_eq2 even more awkward.
* options, vo_x11: remove -zoom option, make it defaultwm42012-11-162-29/+2
| | | | | | | | | | | | | | 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.
* vf_dlopen: fix a typo in zeroing memory (thanks, pigoz)Rudolf Polzer2012-11-131-1/+1
| | | | Accidentally had put the & inside the sizeof call too. Typing too fast.
* Rename directories, move files (step 2 of 2)wm42012-11-1232-161/+162
| | | | | | | | | | | | 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)wm42012-11-1234-0/+11133
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.
