From 1d0349d3b5d9a263251fcb3b0d7e135d4731bfd0 Mon Sep 17 00:00:00 2001 From: Bin Jin Date: Thu, 7 Mar 2019 15:06:24 +0000 Subject: vo_gpu: add two useful operators to user shader modulo operator could be used to check if size is multiple of a certain number. equal operator could be used to verify if size of different textures aligns. --- video/out/gpu/user_shaders.c | 5 +++++ video/out/gpu/user_shaders.h | 2 ++ 2 files changed, 7 insertions(+) diff --git a/video/out/gpu/user_shaders.c b/video/out/gpu/user_shaders.c index 446941b03f..0613eb93f6 100644 --- a/video/out/gpu/user_shaders.c +++ b/video/out/gpu/user_shaders.c @@ -16,6 +16,7 @@ */ #include +#include #include "common/msg.h" #include "misc/ctype.h" @@ -52,9 +53,11 @@ static bool parse_rpn_szexpr(struct bstr line, struct szexp out[MAX_SZEXP_SIZE]) case '-': exp->tag = SZEXP_OP2; exp->val.op = SZEXP_OP_SUB; continue; case '*': exp->tag = SZEXP_OP2; exp->val.op = SZEXP_OP_MUL; continue; case '/': exp->tag = SZEXP_OP2; exp->val.op = SZEXP_OP_DIV; continue; + case '%': exp->tag = SZEXP_OP2; exp->val.op = SZEXP_OP_MOD; continue; case '!': exp->tag = SZEXP_OP1; exp->val.op = SZEXP_OP_NOT; continue; case '>': exp->tag = SZEXP_OP2; exp->val.op = SZEXP_OP_GT; continue; case '<': exp->tag = SZEXP_OP2; exp->val.op = SZEXP_OP_LT; continue; + case '=': exp->tag = SZEXP_OP2; exp->val.op = SZEXP_OP_EQ; continue; } if (mp_isdigit(word.start[0])) { @@ -118,8 +121,10 @@ bool eval_szexpr(struct mp_log *log, void *priv, case SZEXP_OP_SUB: res = op1 - op2; break; case SZEXP_OP_MUL: res = op1 * op2; break; case SZEXP_OP_DIV: res = op1 / op2; break; + case SZEXP_OP_MOD: res = fmodf(op1, op2); break; case SZEXP_OP_GT: res = op1 > op2; break; case SZEXP_OP_LT: res = op1 < op2; break; + case SZEXP_OP_EQ: res = op1 == op2; break; default: abort(); } diff --git a/video/out/gpu/user_shaders.h b/video/out/gpu/user_shaders.h index 8d8cc6bde0..a477e3ce3d 100644 --- a/video/out/gpu/user_shaders.h +++ b/video/out/gpu/user_shaders.h @@ -30,9 +30,11 @@ enum szexp_op { SZEXP_OP_SUB, SZEXP_OP_MUL, SZEXP_OP_DIV, + SZEXP_OP_MOD, SZEXP_OP_NOT, SZEXP_OP_GT, SZEXP_OP_LT, + SZEXP_OP_EQ, }; enum szexp_tag { -- cgit v1.2.3
