TOS supports saving images generated from video frame extraction to a specified storage bucket. This article describes how to use the TOS Go SDK to save images captured from video frames to a specified storage bucket.
Sample Code
The following code demonstrates how to capture the video frame at 300 milliseconds, name the resulting image temp.jpg, and save it to the target storage bucket.
package main
import (
"context"
"encoding/base64"
"encoding/json"
"fmt"
"github.com/volcengine/ve-tos-golang-sdk/v2/tos"
)
func checkErr(err error) {
if err != nil {
if serverErr, ok := err.(*tos.TosServerError); ok {
fmt.Println("Error:", serverErr.Error())
fmt.Println("Request ID:", serverErr.RequestID)
fmt.Println("Response Status Code:", serverErr.StatusCode)
fmt.Println("Response Header:", serverErr.Header)
fmt.Println("Response Err Code:", serverErr.Code)
fmt.Println("Response Err Msg:", serverErr.Message)
} else {
fmt.Println("Error:", err)
}
panic(err)
}
}
type SaveAsResult struct {
Bucket string `json:"bucket"`
FileSize string `json:"fileSize"`
Object string `json:"object"`
Status string `json:"status"`
}
func main() {
var (
accessKey = os.Getenv("TOS_ACCESS_KEY")
secretKey = os.Getenv("TOS_SECRET_KEY")
endpoint = "https://tos-cn-beijing.volces.com"
region = "cn-beijing"
bucketName = "*** Provide your bucket name ***"
videoKey = "video.mp4"
ctx = context.Background()
saveBucket = "*** Provide your bucket name ***"
saveObject = "temp.jpg"
)
client, err := tos.NewClientV2(endpoint, tos.WithRegion(region), tos.WithCredentials(tos.NewStaticCredentials(accessKey, secretKey)))
checkErr(err)
style := "video/snapshot,t_300"
out, err := client.GetObjectV2(ctx, &tos.GetObjectV2Input{Bucket: bucketName, Key: videoKey, Process: style, SaveBucket: base64.URLEncoding.EncodeToString([]byte(saveBucket)), SaveObject: base64.URLEncoding.EncodeToString([]byte(saveObject))})
checkErr(err)
var saveAsResult SaveAsResult
err = json.NewDecoder(out.Content).Decode(&saveAsResult)
checkErr(err)
fmt.Println("Save As Result:", saveAsResult)
}
