The video information retrieval function enables the acquisition of metadata for a specified video resource. This document describes how to obtain video information using the TOS C++ SDK.

Sample Code

The following code demonstrates how to retrieve video information.

#include "TosClientV2.h"​
using namespace VolcengineTos;​
​
int main(void){​
    ​
    ​
    std::string region = "Your Region";​
    std::string accessKey = std::getenv("TOS_ACCESS_KEY");​
    std::string secretKey = std::getenv("TOS_SECRET_KEY");​
    ​
    std::string bucketName = "examplebucket";​
    ​
    std::string objectName = "exampledir/exampleobject.mp4";​
    ​
    ​
    InitializeClient();​
    ​
    TosClientV2 client(region, accessKey, secretKey);​
    ​
    GetObjectV2Input input(bucketName, objectName);​
    std::string style = "video/info";​
    input.setProcess(style);​
    auto output = client.getObject(input);​
    if (!output.isSuccess()) {​
    ​
        std::cout << "GetObjectToFile failed." << output.error().String() << std::endl;​
      ​
        CloseClient();​
        return -1;​
    }​
    ​
    std::ostringstream ss;​
    ss << output.result().getContent()->rdbuf();​
 ​
    std::string infoJson = ss.str();​
    ​
 ​
    CloseClient();​
    return 0;​
}​
