From 5fa45fb5641c95a5dc65faac2087d842333b5425 Mon Sep 17 00:00:00 2001 From: wm4 Date: Mon, 7 Mar 2016 22:20:51 +0100 Subject: osd, lua: remove weird OSD scaling Do not scale OSD mouse input to the ASS OSD script resolution. The original idea of this mechanism was that the user doesn't have to care about the actual resolution of anything, and can just use the OSD resolution consistently. But this made things worse. Remove the implicit scaling, and always use the screen resolution. (Except with --vo=xv, where additional scaling is forced upon everything.) Drop get_osd_resolution(). There is no replacement. Rename get_screen_size() and get_screen_margins() to use "osd" instead of "screen". For anything but --vo=xv these are equivalent, but with --vo=xv the OSD resolution has additional implicit scaling. Add code to osc.lua which emulates the old behavior. Note that none of the changed functions were public API, so implicit breakage of scripts which used it is just going to happen. --- player/lua.c | 36 ++++++++++-------------------------- player/lua/osc.lua | 39 ++++++++++++++++++++++++++++++--------- 2 files changed, 40 insertions(+), 35 deletions(-) (limited to 'player') diff --git a/player/lua.c b/player/lua.c index 9fe1d0deca..04c7dbb977 100644 --- a/player/lua.c +++ b/player/lua.c @@ -974,17 +974,7 @@ static int script_set_osd_ass(lua_State *L) return 0; } -static int script_get_osd_resolution(lua_State *L) -{ - struct MPContext *mpctx = get_mpctx(L); - int w, h; - osd_object_get_resolution(mpctx->osd, OSDTYPE_EXTERNAL, &w, &h); - lua_pushnumber(L, w); - lua_pushnumber(L, h); - return 2; -} - -static int script_get_screen_size(lua_State *L) +static int script_get_osd_size(lua_State *L) { struct MPContext *mpctx = get_mpctx(L); struct mp_osd_res vo_res = osd_get_vo_res(mpctx->osd, OSDTYPE_EXTERNAL); @@ -996,7 +986,7 @@ static int script_get_screen_size(lua_State *L) return 3; } -static int script_get_screen_margins(lua_State *L) +static int script_get_osd_margins(lua_State *L) { struct MPContext *mpctx = get_mpctx(L); struct mp_osd_res vo_res = osd_get_vo_res(mpctx->osd, OSDTYPE_EXTERNAL); @@ -1012,10 +1002,8 @@ static int script_get_mouse_pos(lua_State *L) struct MPContext *mpctx = get_mpctx(L); int px, py; mp_input_get_mouse_pos(mpctx->input, &px, &py); - double sw, sh; - osd_object_get_scale_factor(mpctx->osd, OSDTYPE_EXTERNAL, &sw, &sh); - lua_pushnumber(L, px * sw); - lua_pushnumber(L, py * sh); + lua_pushnumber(L, px); + lua_pushnumber(L, py); return 2; } @@ -1030,14 +1018,11 @@ static int script_input_set_section_mouse_area(lua_State *L) { struct MPContext *mpctx = get_mpctx(L); - double sw, sh; - osd_object_get_scale_factor(mpctx->osd, OSDTYPE_EXTERNAL, &sw, &sh); - char *section = (char *)luaL_checkstring(L, 1); - int x0 = sw ?
