* libav_compat: fix mmx2 define, provide fallback for avcodec_free_frameStefano Pigozzi2012-11-031-1/+1

* image_writer: add dump_png() function as debugging helperwm42012-11-011-0/+7

* screenshot: remove hack for passing anamorphic image sizewm42012-11-011-7/+5
| | | | | | | | | | With anamorphic video (display with non-1:1 PAR, e.g. DVD), the display size was passed using the mp_image fields w/h, which was blatantly incorrect. w/h are the normal image dimensions, while width/height are the "uncropped" storage size (used internally by vf.c). Add a display_w/h, and use that for the display size. Make all VOs that can do screenshots use it.
* screenshot: let VOs pass colorspace information via mp_imagewm42012-11-011-3/+3
| | | | | | | | | This removes the hack that screenshot_save() got the colorspace information from the decoder. Instead, require the VOs to set the colorspace information on the mp_images used to pass around the screenshot data. This is more correct, as the image may have been converted/modified in the video filter chain, although there's nothing yet in the video filter chain which does this correctly.
* screenshot, draw_bmp: use colorspace passed with mp_imagewm42012-11-011-20/+12
| | | | | Remove the explicit struct mp_csp_details parameters from all related functions, and use mp_image.colorspace/levels instead.
* libmpcodecs: move vf_scale.c swscale helper functions to sws_utils.cRudolf Polzer2012-10-241-1/+1
| | | | | Extracted/rebased by wm4 from commits 93978f17b76d..13211ef5fc20. Actual mp_image_swscale is added in a later commit.
* image_writer: make JPG default and increase quality (for screenshots)wm42012-08-161-2/+2
| | | | | | | | | The assumption is that JPG screenshots are more useful in general. Lossless screenshots made from lossy videos are just a waste of space. Increase JPEG quality a bit. There's a tradeoff between quality and size, and since JPEG is the default now, attempt to balance the JPEG settings to provide sane defaults for general use cases.
* image_writer: rename "filetype" option to "format"wm42012-08-061-3/+3
| | | | | | | Although slightly less precise, this sounds less clunky. This change also causes the --screenshot-filetype option to be renamed to --screenshot-format.
* image_writer: support all JPEG specific options vo_jpeg supportswm42012-08-061-1/+27
| | | | | | Most of these are useless or probably even dangerous. Support them anyway, because it's easy, and we want to replace vo_jpeg without any disadvantages.
* image_writer: add TGA image formatwm42012-08-061-0/+5
| | | | | | For getting rid of vo_tga. This makes use of the libavcodec TGA encoder.
* image_writer: add some PNM family image formatswm42012-08-061-9/+20
| | | | | | | | | | While the PNM formats are not that useful, supporting them helps getting rid of vo_pnm. This makes use of the libavcodec PNM encoder. Compared to vo_pnm, at least PNM ASCII mode is not supported. It doesn't look like libavcodec supports this mode for encoding.
* image_writer: add option parsingwm42012-08-061-0/+14
| | | | | image_writer now provides its own option parsing, and screenshot.c and the mplayer frontend use it.
* image_writer: allow specifying pixel formats for image writerswm42012-08-061-2/+13
|
* image_writer: never pass anamorphic images to image writerwm42012-08-061-1/+2

* screenshot: move image writer code into new file image_writer.cwm42012-08-061-0/+262
