The video frame extraction function enables the capture of a single frame from a video stream at a specified time and resizes it into an image of the designated dimensions.

Sample Code

The following code demonstrates how to extract the video frame at 1000 milliseconds and download the resulting image to the local device.

​
TOSCredential *credential = [[TOSCredential alloc] initWithAccessKey:@"accesskey" secretKey:@"secretkey" securityToken:@"securityToken"];​
TOSEndpoint *tosEndpoint = [[TOSEndpoint alloc] initWithURLString:@"endpoint" withRegion:@"region"];​
TOSClientConfiguration *config = [[TOSClientConfiguration alloc] initWithEndpoint:tosEndpoint credential:credential];​
TOSClient *client = [[TOSClient alloc] initWithConfiguration:config];​
​
TOSGetObjectToFileInput *get = [TOSGetObjectToFileInput new];​
get.tosBucket = @"bucket-name";​
get.tosKey = @"video-name";​
get.tosFilePath = @"your_local_file_path";​
get.tosProcess = @"video/snapshot,t_1000";​
TOSTask *task = [client getObjectToFile:get];​
[task continueWithBlock:^id _Nullable(TOSTask * _Nonnull t) {​
    if (!t.error) {​
        NSLog(@"Get object to file success.");​
    } else {​
        NSLog(@"Get object to file failed, error: %@" ,t.error);​
    }​
    return nil;​
}];​
