我正在尝试在 ffmpeg 1.2中编译和运行resampling_audio.c 。似乎有一个错误和代码段错误。我调试了代码，它似乎正在崩溃

/* convert to destination format */
ret = swr_convert(swr_ctx, dst_data, dst_nb_samples, (const uint8_t **)src_data, src_nb_samples);
if (ret < 0) {
    fprintf(stderr, "Error while converting\n");
    goto end;
}
dst_bufsize = av_samples_get_buffer_size(&dst_linesize, dst_nb_channels,
                                             ret, dst_sample_fmt, 1);

堆栈跟踪是
