Permission denied on RunWithResource

[dhanielsales]

I'm trying to run a command with Run With Resource and i receive a permission denied error like above

OS: Fedora 37
GO version: go1.20.4 linux/amd64

Error:

panic: mkdir /sys/fs/cgroup/cpu,cpuacct/ffmpeg_go_2wtdg9: permission denied

goroutine 47 [running]:

        /home/dhanielsales/MyProjects/video-preview-progress/main.go:45 +0x432

        /home/dhanielsales/MyProjects/video-preview-progress/main.go:32 +0xc5
exit status 2

Code:

package main

import (
	"encoding/json"
	"fmt"
	"strconv"
	"sync"

	ffmpeg "github.com/u2takey/ffmpeg-go"
)

func main() {
	a, err := ffmpeg.Probe("./video.mp4")
	if err != nil {
		panic(err)
	}

	totalDuration, err := probeDuration(a)
	if err != nil {
		panic(err)
	}

	totalSeconds := int(totalDuration)

	totalIntervals := totalSeconds / 10

	var wg sync.WaitGroup

	wg.Add(totalIntervals)

	for i := 1; i <= totalIntervals; i++ {
		go func(interval int) {
			defer wg.Done()
			currentTime := interval * 10

			if currentTime <= totalSeconds {
				err := ffmpeg.
					Input("./video.mp4").
					Output(fmt.Sprintf("outputs/output%d.jpg", interval), ffmpeg.KwArgs{"ss": fmt.Sprintf("%d", interval*10), "frames:v": "1", "q:v": "2", "vf": "scale=160:96"}).
					OverWriteOutput().
					ErrorToStdOut().
					RunWithResource(0.1, 0.5)

				if err != nil {
					panic(err)
				}
			}
		}(i)
	}

	wg.Wait()
}

type probeFormat struct {
	Duration string `json:"duration"`
}

type probeData struct {
	Format probeFormat `json:"format"`
}

func probeDuration(a string) (float64, error) {
	pd := probeData{}
	err := json.Unmarshal([]byte(a), &pd)

	if err != nil {
		return 0, err
	}

	f, err := strconv.ParseFloat(pd.Format.Duration, 64)

	if err != nil {
		return 0, err
	}

	return f, nil
}

I already try to build and run the code with Sudo but receive the same error.

did you managed to fix this? i have the same problem

[rhuanpk]

same here, without sudo:

mkdir /sys/fs/cgroup/cpu,cpuacct: permission denied

with sudo:

open /sys/fs/cgroup/cpu,cpuacct/ffmpeg_go_fvdwwd/cpu.shares: permission denied

[dhanielsales]

@ashkan-esz @rhuanpk unfortunately I couldn't fix it by myself and I changed the package

[rhuanpk]

@dhanielsales what's the package you choosen?

@dhanielsales what's the package you choosen?

OpenCV, but we changed the approach completely.
