• FFMPEG : Error writing trailer of v%v/index.m3u8 : Cannot allocate memory

  7 avril 2023, par user3309447

  I wanted to convert one video track and 2 audio tracks to HLS by combining them.
That means, the HLS conversion has to be multi-bitrate and multi-language both.

  


  What do I want to achieve ?
I have to prepare an HLS stream for 3 resolutions, namely, 720px, 480px and 360px.
Also, there will be 2 audio tracks in the resultant stream, one English and another Hindi.
I am running the below command and getting the error as described below.
Can anybody help me out ?

  


  Command :

• Could not find ref with POC ffmpeg H265

  7 juin 2021, par user1307697

  I'm trying to develop a video streaming with H265. Unfortunately, in decoding phase, I have these errors :

  


  [hevc @ 0x5563d05b4940] Could not find ref with POC

  


  and the resulting frames are corrupted.

  


  I cannot understand the meaning of this type of error. How can I fix it ?

  


• Generating DASH manifest with ffmpeg works in Docker exec shell but not in os.exec golang

  22 février 2023, par Inquisitor

  I 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})
