获取库文件

在官网下载“Dev”版的压缩包，内含`mpv-1.dll`文件。务必从此处下载，这个版本的编译包含i686/x64两种架构，通常使用i686版本是正确的。使用错误版本的.dll文件会导致0xc000007b错误。

编译

以最简单的simple.c为例。目录结构为：

simple-mpv
    | simple.c
    | mpv-1.dll
    | include
    |    | client.h
    |    | ...headers

simple.c源代码：

#include <stddef.h>
#include <stdio.h>
#include <stdlib.h>

#include "include/client.h"

static inline void check_error(int status)
{
	if (status < 0)
	{
		printf("mpv API error: %s\n", mpv_error_string(status));
		exit(1);
	}
}

int main(int argc, char* argv[])
{
	printf("pass a single media file as argument\n");
	if (argc != 2)
	{
		printf("pass a single media file as argument\n");
		return 1;
	}

	mpv_handle* ctx = mpv_create();
	if (!ctx)
	{
		printf("failed creating context\n");
		return 1;
	}

	// Enable default key bindings, so the user can actually interact with
	// the player (and e.g. close the window).
	check_error(mpv_set_option_string(ctx, "input-default-bindings", "yes"));
	mpv_set_option_string(ctx, "input-vo-keyboard", "yes");
	int val = 1;
	check_error(mpv_set_option(ctx, "osc", MPV_FORMAT_FLAG, &val));

	// Done setting up options.
	check_error(mpv_initialize(ctx));

	// Play this file.
	const char* cmd[] = { "loadfile", argv[1], NULL };
	check_error(mpv_command(ctx, cmd));

	// Let it play, and wait until the user quits.
	while (1)
	{
		mpv_event* event = mpv_wait_event(ctx, 10000);
		printf("event: %s\n", mpv_event_name(event->event_id));
		if (event->event_id == MPV_EVENT_SHUTDOWN)
			break;
	}

	mpv_terminate_destroy(ctx);
	return 0;
}

则编译脚本为：

gcc -o simple.exe simple.c mpv-1.dll

此处使用的是MinGW环境，在此环境下的链接器支持直接链接.dll文件。如果使用了正确的mpv-1.dll，则程序应该能正常运行。
