From 28d12a899645be09dae7e4cb8c293bf7fc64d6ad Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Thu, 30 Nov 2023 11:34:15 -0800 Subject: til: wire up til_video_setup_t throughout *_fb Preparatory commit for aspect ratio settings at the fb layer. This slightly reworks how main::setup_video() integrates the selected fb backend's setup_func to better resemble how the module setup_funcs work now, with more clearly separated settings-building and setup-baking/finalizing phases. Which makes inserting the ratio setting in the middle of the front-end and back-end setup_funcs fairly trivial. Not a fan of all the casts, but there will probably be more helpers introduced to take care of that and make til_video_setup_t more of a first-class thing facilitating the fb stuff. --- src/drm_fb.c | 7 ++++--- src/main.c | 56 +++++++++++++++++++++++++++++++++----------------------- src/mem_fb.c | 9 +++++---- src/sdl_fb.c | 15 ++++++++------- src/til_fb.c | 5 +++-- src/til_fb.h | 5 +++-- 6 files changed, 56 insertions(+), 41 deletions(-) diff --git a/src/drm_fb.c b/src/drm_fb.c index 5d7f259..2dd4f98 100644 --- a/src/drm_fb.c +++ b/src/drm_fb.c @@ -14,6 +14,7 @@ #include "til_fb.h" #include "til_settings.h" #include "til_util.h" +#include "til_video_setup.h" /* drm fb backend, everything drm-specific in rototiller resides here. */ typedef struct drm_fb_page_t drm_fb_page_t; @@ -37,7 +38,7 @@ typedef struct drm_fb_t { } drm_fb_t; typedef struct drm_fb_setup_t { - til_setup_t til_setup; + til_video_setup_t til_video_setup; const char *dev; const char *connector; const char *mode; @@ -330,7 +331,7 @@ static drmModeModeInfo * lookup_mode(drmModeConnector *connector, const char *mo /* prepare the drm context for use with the supplied settings */ -static int drm_fb_init(const char *title, const til_setup_t *setup, void **res_context) +static int drm_fb_init(const char *title, const til_video_setup_t *setup, void **res_context) { drm_fb_setup_t *s = (drm_fb_setup_t *)setup; drm_fb_t *c; @@ -598,7 +599,7 @@ static int drm_fb_setup(const til_settings_t *settings, til_setting_t **res_sett if (!setup) return -ENOMEM; - return til_settings_apply_desc_generators(settings, generators, nelems(generators), &setup->til_setup, res_setting, res_desc, res_setup); + return til_settings_apply_desc_generators(settings, generators, nelems(generators), &setup->til_video_setup.til_setup, res_setting, res_desc, res_setup); } diff --git a/src/main.c b/src/main.c index c4e4c4e..df2d219 100644 --- a/src/main.c +++ b/src/main.c @@ -17,6 +17,7 @@ #include "til_settings.h" #include "til_stream.h" #include "til_util.h" +#include "til_video_setup.h" #include "fps.h" #include "setup.h" @@ -80,14 +81,14 @@ static rototiller_t rototiller; typedef struct setup_t { - til_settings_t *module_settings; - til_setup_t *module_setup; - til_settings_t *audio_settings; - til_setup_t *audio_setup; - til_settings_t *video_settings; - til_setup_t *video_setup; - unsigned seed; - const char *title; + til_settings_t *module_settings; + til_setup_t *module_setup; + til_settings_t *audio_settings; + til_setup_t *audio_setup; + til_settings_t *video_settings; + til_video_setup_t *video_setup; + unsigned seed; + const char *title; } setup_t; /* FIXME: this is unnecessarily copy-pasta, i think modules should just be made @@ -153,6 +154,7 @@ static int setup_video(const til_settings_t *settings, til_setting_t **res_setti { til_setting_t *setting; const char *video; + int r; video = til_settings_get_value_by_idx(settings, 0, &setting); if (!video || !setting->desc) { @@ -166,7 +168,6 @@ static int setup_video(const til_settings_t *settings, til_setting_t **res_setti #endif NULL, }; - int r; r = til_setting_desc_new( settings, &(til_setting_spec_t){ @@ -189,26 +190,35 @@ static int setup_video(const til_settings_t *settings, til_setting_t **res_setti /* XXX: this is kind of hacky for now */ #ifdef HAVE_DRM - if (!strcasecmp(video, "drm")) { + if (!strcasecmp(video, "drm")) fb_ops = &drm_fb_ops; - - return drm_fb_ops.setup(settings, res_setting, res_desc, res_setup); - } #endif - if (!strcasecmp(video, "mem")) { + if (!strcasecmp(video, "mem")) fb_ops = &mem_fb_ops; - - return mem_fb_ops.setup(settings, res_setting, res_desc, res_setup); - } #ifdef HAVE_SDL - if (!strcasecmp(video, "sdl")) { + if (!strcasecmp(video, "sdl")) fb_ops = &sdl_fb_ops; +#endif + if (!fb_ops) { + *res_setting = setting; + return -EINVAL; + } - return sdl_fb_ops.setup(settings, res_setting, res_desc, res_setup); + r = fb_ops->setup(settings, res_setting, res_desc, NULL); + if (r) + return r; + + if (res_setup) { /* now to finalize/bake the setup */ + til_video_setup_t *setup; + + r = fb_ops->setup(settings, res_setting, res_desc, (til_setup_t **)&setup); + if (r) + return r; + + *res_setup = &setup->til_setup; } -#endif - return -EINVAL; + return 0; } @@ -319,7 +329,7 @@ static int setup_from_args(til_args_t *args, setup_t *res_setup, const char **re if (r) changes = 1; - r = setup_interactively(setup.video_settings, setup_video, args->use_defaults, &setup.video_setup, res_failed_desc_path); + r = setup_interactively(setup.video_settings, setup_video, args->use_defaults, (til_setup_t **)&setup.video_setup, res_failed_desc_path); if (r < 0) goto _err; if (r) @@ -531,7 +541,7 @@ int main(int argc, const char *argv[]) { /* free setup (move to function? and disambiguate from til_setup_t w/rename?
