From 96e1f1dfa587a4f21e8a7264ab9e28fad7e5739b Mon Sep 17 00:00:00 2001 From: nanahi <130121847+na-na-hi@users.noreply.github.com> Date: Mon, 15 Apr 2024 22:47:20 -0400 Subject: video/out/gpu/context: convert --gpu-context to use obj_settings_list Since the list of available GPU contexts is a compile time constant, use obj_settings_list instead of opt_string_validate for GPU contexts. This has several advantages: - Aligns with the existing usage of vo, ao, and filter lists. - Allows custom probing order. - Allows list option suffixes. (--gpu-context-append, etc.) - Allows autocomplete in console.lua. - Uses the standard obj_settings_list help printing, so the custom help printing function is no longer needed. This also deduplicates some context creation code for ra_ctx_create and ra_ctx_create_by_name. --- player/command.c | 2 +- video/out/gpu/context.c | 187 +++++++++++++++++++++++++----------------------- video/out/gpu/context.h | 2 +- 3 files changed, 101 insertions(+), 90 deletions(-) diff --git a/player/command.c b/player/command.c index 190b1fc025..b7130814d8 100644 --- a/player/command.c +++ b/player/command.c @@ -7306,7 +7306,7 @@ void mp_option_change_callback(void *ctx, struct m_config_option *co, int flags, } if (opt_ptr == &opts->vo->video_driver_list || - opt_ptr == &opts->ra_ctx_opts->context_name || + opt_ptr == &opts->ra_ctx_opts->context_list || opt_ptr == &opts->ra_ctx_opts->context_type) { struct track *track = mpctx->current_track[0][STREAM_VIDEO];
