* vo_gpu: make screenshots use the GL rendererwm42018-02-111-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Using the GL renderer for color conversion will make sure screenshots will use the same conversion as normal video rendering. It can do this for all types of screenshots. The logic when to write 16 bit PNGs changes. To approximate the old behavior, we decide by looking whether the source video format has more than 8 bits per component. We apply this logic even for window screenshots. Also, 16 bit PNGs now always include an unused alpha channel. The reason is that FFmpeg has RGB48 and RGBA64 formats, but no RGB064. RGB48 is 3 bytes and usually not supported by GPUs for rendering, so we have to use RGBA64, which forces an alpha channel. Will break for users who use --target-trc and similar options. I considered creating a new gl_video context, but it could double GPU memory use, so I didn't. This uses FBOs instead of glGetTexImage(), because that increases the chance it could work on GLES (e.g. ANGLE). Untested. No support for the Vulkan and D3D11 backends yet. Fixes #5498. Also fixes #5240, because the code for reading back is not used with the new code path.
* image_writer, vo_image: change license to LGPLwm42017-06-181-7/+7
| | | | | | | | | | | | | | | | | | image_writer.c has code originating from vf_screenshot.c, vo_jpeg.c, and potentially others. vo_image.c is based on a bunch of those VOs as well, and the intention was to replace them with a single codebase. vo_tga.c was written by someone who was not or not could be contacted, but it doesn't matter anyway, as no code from that initial patch was used. One rather old patch (57f77bb41a9) reordered by libjpeg patch API calls, and the author of the patch was not contacted. But at least with the smoothing_factor override removed, this pretty much exactly corresponds to the official libjpeg API example (and might even reflect a change to those - didn't dig deeper). This removes the -jpeg-smooth option. While we're at it, remove all the other dropped jpeg options from the manpage (which was forgotten in past changes).
* screenshot: change details of --screenshot-format handlingwm42017-03-181-1/+4
| | | | | | | | | | | | | | | | This is just a pointless refactor with the only goal of making image_writer_opts.format a number. The pointless part of it is that instead of using some sort of arbitrary ID (in place of a file extension string), we use a AV_CODEC_ID_. There was also some idea of falling back to the libavcodec MJPEG encoder if mpv was not linked against libjpeg, but this fails. libavcodec insist on having AV_PIX_FMT_YUVJ420P, which we pretend does not exist, and which we always map to AV_PIX_FMT_YUV420P (without the J indicating full range), so encoder init fails. This is pretty dumb, but whatever. The not-caring factor is raised by the fact that we don't know that we should convert to full range, because encoders have no proper way to signal this. (Be reminded that AV_PIX_FMT_YUVJ420P is deprecated.)
* vo_image: move to global optionswm42016-09-051-1/+3
| | | | | This is a bit "special", because the config tree wants unique m_sub_options pointers in the whole thing.
* screenshots: add option to prevent 16 bit outputwm42015-04-291-0/+1
| | | | That's what it's usually about (again).
* screenshots: add option to disable JPEG 4:4:4 outputwm42015-04-291-0/+1
| | | | That's what it's usually about.
* image_writer: factor image conversion into a separate functionwm42015-04-201-0/+6
| | | | Needed for a later commit.
* image_writer: minor cleanupwm42015-04-201-2/+2
| | | | Instead of using int like bool, use bool directly.

* Revert recent vo_opengl related commitswm42015-02-281-1/+0
| | | | | | | | | | | | | | | Breaks vo_opengl by default. I'm hot able to fix this myself, because I have no clue about the overcomplicated color management logic. Also, whilethis is apparently caused by commit fbacd5, the following commits all depend on it, so revert them too. This reverts the following commits: e141caa97dade07f4d7e0d6c208bcd3493e712ed 653b0dd5295453d9661f673b4ebd02c5ceacf645 729c8b3f641e633474be612e66388c131a1b5c92 fbacd5de31de964f7cd562304ab1c9b4a0d76015 Fixes #1636.
* screenshots: add support for csp taggingNiklas Haas2015-02-281-0/+1
| | | | | | This relies on upstream support in lavc, and will hence basically not work at all. The intent is to get support for writing this information into ffmpeg's PNG encoders etc.
* image_writer: mp_msg conversionswm42013-12-211-3/+3
| | | | Adds an awkward mp_log argument for error messages.
* image_writer: Add PNG filter option (default "mixed")Martin Herkt2013-06-151-0/+1
| | | | | | The use of filters prior to PNG compression can greatly improve compression ratio, with "mixed" (ImageMagick calls it "adaptive") typically achieving the best results.
* Rename directories, move files (step 1 of 2) (does not compile)wm42012-11-121-0/+53
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.
