HarmonyOS 鸿蒙Next求大佬帮忙分析下为什么ffmpeg会闪退

我编译ffmpeg到so, 然后使用官方的ffmpeg.c更改了其中的int main方法

int exe_ffmpeg_cmd(int argc, char **argv, Callbacks* callback)
{
    int i, ret;
    BenchmarkTimeStamps ti;

    init_dynload();

    register_exit(ffmpeg_cleanup);

    setvbuf(stderr,NULL,_IONBF,0); /* win32 runtime needs this */

    av_log_set_flags(AV_LOG_SKIP_REPEATED);
    parse_loglevel(argc, argv, options);

    if(argc>1 && !strcmp(argv[1], "-d")){
        run_as_daemon=1;
        av_log_set_callback(log_callback_null);
        argc--;
        argv++;
    }

#if CONFIG_AVDEVICE
    avdevice_register_all();
#endif
    avformat_network_init();

    show_banner(argc, argv, options);

    /* parse options and open all input/output files */
    ret = ffmpeg_parse_options(argc, argv);
    if (ret < 0) {
        exit_program(ret);
        main_return_code = 1;
    }

    if (nb_output_files <= 0 && nb_input_files == 0) {
        show_usage();
        av_log(NULL, AV_LOG_WARNING, "Use -h to get full help or, even better, run 'man %s'\n", program_name);
        exit_program(1);
        main_return_code = 1;
    }

    /* file converter / grab */
    if (nb_output_files <= 0) {
        av_log(NULL, AV_LOG_FATAL, "At least one output file must be specified\n");
        exit_program(1);
        main_return_code = 1;
    }

//     if (nb_input_files == 0) {
//         av_log(NULL, AV_LOG_FATAL, "At least one input file must be specified\n");
//         exit_program(1);
//     }

    for (i = 0; i < nb_output_files; i++) {
        if (strcmp(output_files[i]->ctx->oformat->name, "rtp"))
            want_sdp = 0;
    }

    current_time = ti = get_benchmark_time_stamps();
    if (transcode(callback) < 0) {
        exit_program(1);
        main_return_code = 1;
    }
    if (do_benchmark) {
        int64_t utime, stime, rtime;
        current_time = get_benchmark_time_stamps();
        utime = current_time.user_usec - ti.user_usec;
        stime = current_time.sys_usec  - ti.sys_usec;
        rtime = current_time.real_usec - ti.real_usec;
        av_log(NULL, AV_LOG_INFO,
               "bench: utime=%0.3fs stime=%0.3fs rtime=%0.3fs\n",
               utime / 1000000.0, stime / 1000000.0, rtime / 1000000.0);
    }
    av_log(NULL, AV_LOG_DEBUG, "%"PRIu64" frames successfully decoded, %"PRIu64" decoding errors\n",
           decode_error_stat[0], decode_error_stat[1]);
    if ((decode_error_stat[0] + decode_error_stat[1]) * max_error_rate < decode_error_stat[1]) {
        exit_program(69);
        main_return_code = 69;
    }

    //exit_program(received_nb_signals ? 255 : main_return_code);
    ffmpeg_cleanup(0);
    return main_return_code;
}

去掉了其中的exit_program的中断退出方法

int exit_program(int ret)
{
    if (program_exit)
        program_exit(ret);
//<span class="hljs-keyword"><span class="hljs-keyword">exit</span></span>(ret);
<span class="hljs-keyword"><span class="hljs-keyword">return</span></span> ret;
}
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 4px; right: 8px; font-size: 14px;">复制</button>

按道理是不会闪退的吧? 正常运行命令没问题, 但是只要ffmpeg的命令运行出错, 比如输入的文件不存在, 输入的文件内容错误就会闪退. 闪退的报错很诡异 是在打印日志的地方闪退

void log_call_back(void *ptr, int level, const char *fmt, va_list vl) {
    static int print_prefix = 1;
    static int count;
    static char prev[1024];
    char line[1024];
    static int is_atty;
    av_log_format_line(ptr, level, fmt, vl, line, sizeof(line), &print_prefix);
    strcpy(prev, line);
    OH_LOG_ERROR(LOG_APP, "========> %{public}s", line);
}
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 4px; right: 8px; font-size: 14px;">复制</button>

大概是strcpy这些位置会闪退

 strcpy(prev, line);
 OH_LOG_ERROR(LOG_APP, "========> %{public}s", line);
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 4px; right: 8px; font-size: 14px;">复制</button>

请问各位有什么思路吗?
