c语言播放视频或动图的代码

C语言本身没有直接播放视频或动图的功能，需要通过调用其他库或工具来实现。以下是使用SDL库播放视频和动图的示例代码：

播放视频：

#include <stdio.h>
#include <SDL2/SDL.h>

int main(int argc, char *argv[]) {
    if (SDL_Init(SDL_INIT_VIDEO) < 0) {
        printf("SDL_Init failed: %s\n", SDL_GetError());
        return -1;
    }

    SDL_Window *window = SDL_CreateWindow("Video Player", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 640, 480, SDL_WINDOW_OPENGL);
    if (!window) {
        printf("SDL_CreateWindow failed: %s\n", SDL_GetError());
        SDL_Quit();
        return -1;
    }

    SDL_Renderer *renderer = SDL_CreateRenderer(window, -1, 0);
    if (!renderer) {
        printf("SDL_CreateRenderer failed: %s\n", SDL_GetError());
        SDL_DestroyWindow(window);
        SDL_Quit();
        return -1;
    }

    SDL_Surface *surface = SDL_LoadBMP("video.bmp");
    if (!surface) {
        printf("SDL_LoadBMP failed: %s\n", SDL_GetError());
        SDL_DestroyRenderer(renderer);
        SDL_DestroyWindow(window);
        SDL_Quit();
        return -1;
    }

    SDL_Texture *texture = SDL_CreateTextureFromSurface(renderer, surface);
    if (!texture) {
        printf("SDL_CreateTextureFromSurface failed: %s\n", SDL_GetError());
        SDL_FreeSurface(surface);
        SDL_DestroyRenderer(renderer);
        SDL_DestroyWindow(window);
        SDL_Quit();
        return -1;
    }

    SDL_FreeSurface(surface);

    SDL_Rect rect;
    rect.x = 0;
    rect.y = 0;
    rect.w = 640;
    rect.h = 480;

    SDL_Event event;
    int quit = 0;

    while (!quit) {
        while (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                quit = 1;
                break;
            }
        }

        SDL_RenderClear(renderer);
        SDL_RenderCopy(renderer, texture, NULL, &rect);
        SDL_RenderPresent(renderer);
    }

    SDL_DestroyTexture(texture);
    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}

播放动图：

#include <stdio.h>
#include <SDL2/SDL.h>

int main(int argc, char *argv[]) {
    if (SDL_Init(SDL_INIT_VIDEO) < 0) {
        printf("SDL_Init failed: %s\n", SDL_GetError());
        return -1;
    }

    SDL_Window *window = SDL_CreateWindow("GIF Player", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, 640, 480, SDL_WINDOW_OPENGL);
    if (!window) {
        printf("SDL_CreateWindow failed: %s\n", SDL_GetError());
        SDL_Quit();
        return -1;
    }

    SDL_Renderer *renderer = SDL_CreateRenderer(window, -1, 0);
    if (!renderer) {
        printf("SDL_CreateRenderer failed: %s\n", SDL_GetError());
        SDL_DestroyWindow(window);
        SDL_Quit();
        return -1;
    }

    SDL_Surface *surface = SDL_LoadBMP("animation.bmp");
    if (!surface) {
        printf("SDL_LoadBMP failed: %s\n", SDL_GetError());
        SDL_DestroyRenderer(renderer);
        SDL_DestroyWindow(window);
        SDL_Quit();
        return -1;
    }

    SDL_Rect rect;
    rect.x = 0;
    rect.y = 0;
    rect.w = 640;
    rect.h = 480;

    SDL_Event event;
    int quit = 0;
    int frame = 0;

    while (!quit) {
        while (SDL_PollEvent(&event)) {
            if (event.type == SDL_QUIT) {
                quit = 1;
                break;
            }
        }

        SDL_Rect clip;
        clip.x = (frame % 10) * 64;
        clip.y = (frame / 10) * 64;
        clip.w = 64;
        clip.h = 64;

        SDL_Texture *texture = SDL_CreateTextureFromSurface(renderer, surface);
        if (!texture) {
            printf("SDL_CreateTextureFromSurface failed: %s\n", SDL_GetError());
            SDL_FreeSurface(surface);
            SDL_DestroyRenderer(renderer);
            SDL_DestroyWindow(window);
            SDL_Quit();
            return -1;
        }

        SDL_RenderClear(renderer);
        SDL_RenderCopy(renderer, texture, &clip, &rect);
        SDL_RenderPresent(renderer);

        SDL_DestroyTexture(texture);

        frame++;
        if (frame >= 64) {
            frame = 0;
        }

        SDL_Delay(100);
    }

    SDL_FreeSurface(surface);
    SDL_DestroyRenderer(renderer);
    SDL_DestroyWindow(window);
    SDL_Quit();

    return 0;
}

需要注意的是，这里的示例代码仅供参考，实际使用时需要根据具体情况进行修改和调整。
