Building FFmpeg with NVIDIA GPU Hardware Acceleration in docker image, cannot load libnvcuvid.so.1 and libnvidia-encode.so.1
22 mars 2023, par konovificationI'm trying to build FFmpeg with NVIDIA GPU Hardware Acceleration following these instructions : https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/index.html#compiling-for-linux. The Docker image I'm using is

Generating DASH manifest with ffmpeg works in Docker exec shell but not in os.exec golang
22 février 2023, par InquisitorI am trying to generate a DASH manifest with ffmpeg using this command


/usr/bin/ffmpeg -f webm_dash_manifest -i ./480.webm -f webm_dash_manifest -i ./audio.webm -c copy -map 0:0 -map 1:0 -y -f webm_dash_manifest -adaptation_sets "id=0,streams=0 id=1,streams=1" ./manifest.mpd -loglevel repeat+level+verbose



I run this in go, in a docker container as shown :


func runFFmpeg(arguments []string) {
 arguments = append(arguments, "-loglevel", "repeat+level+verbose")
 cmd := exec.Command("ffmpeg", arguments...)

 fmt.Printf("cmd: %v\n", cmd)

 var out bytes.Buffer
 var stderr bytes.Buffer
 cmd.Stdout = &out
 cmd.Stderr = &stderr
 err := cmd.Run()

 if err != nil {
 log.Println(err)
 log.Println(stderr.String())
 }
}
runFFmpeg([]string{"-f", "webm_dash_manifest", "-i", "./480.webm", "-f", "webm_dash_manifest", "-i", "./audio.webm", "-c", "copy", "-map", "0:0", "-map", "1:0", "-y", "-f", "webm_dash_manifest", "-adaptation_sets", "\"id=0,streams=0 id=1,streams=1\"", "./manifest.mpd"})



But I get this output :


cmd: /usr/bin/ffmpeg -f webm_dash_manifest -i ./480.webm -f webm_dash_manifest -i ./audio.webm -c copy -map 0:0 -map 1:0 -y -copy_unknown -f webm_dash_manifest -adaptation_sets "id=0,streams=0 id=1,streams=1" ./manifest.mpd -loglevel repeat+level+verbose

It works perfectly however if I run it within docker exec (exec into the container and run the command in bash). Also, note in the last output that the command is well formed when I print it out from go. File permissions are also not the problem since the command to create the video variants works with os.exec i.e


runFFmpeg([]string{"-i", originalFilePath, "-c:v", "libvpx-vp9", "-keyint_min", "150", "-g", "150", "-tile-columns", "4", "-frame-parallel", "1", "-f", "webm", "-dash", "1", "-an", "-vf", fmt.Sprintf("scale=%s:%s", width, height), "-b:v", bitRate, "-dash", "1", "-y", destinationFilePath})
