• Aws-sdk-php putobject with ffmpeg .m3u8 & .ts format

  13 avril 2018, par Waqas Mani

  I can’t send hls video. aws-sdk-php mp4 video working well but hls videos only send .m3u8 file all .ts file come in local storage

  Here my actual code. Submit-ffmpeg.php :

    $ffmpeg_b = $pt->config->ffmpeg_binary_file;
  
    $filepath = explode('.', $_POST['video-location'])[0];
  
    $time     = time();
  
    $full_dir = str_replace('ajax', '/', __DIR__);
  
  
  
   $structure = $filepath;
  
  
  
   if (!mkdir($structure, 0777, true)) {
  
     die('Failed to create folders...');
  
   }
  
   $hls_link = $structure . "/_360p_converted.m3u8";
  
  
  
   $video_file_full_path = $full_dir . $_POST['videolocation'];
  
   $shell                = shell_exec("$ffmpeg_b -y -i $video_file_full_path -vcodec copy -acodec copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls $hls_link 2>&1");
  
   $upload_s3            = PT_UploadToS3($filepath . "/_360p_converted.m3u8");
  
   $db->where('id', $insert);
  
   $db->update(T_VIDEOS, array( 
  
     'converted' => 1,
  
     '360p' => 1,
  
     'video_location' => $filepath . "/_360p_converted.m3u8"
  
   ));

  function.php
  the sent file in aws-sdk-php

   $s3->putObject([
  
      'Bucket' => $pt->config->s3_bucket_name,
  
      'Key'    => $filename,
  
      'Body'   => fopen($filename, 'r+'),
  
      'ACL'    => 'public-read',
  
   ]);

• ffmpeg does not fill in my provided buffer

  14 avril 2018, par thelearner

  I’m trying to pipe a mp4 video to ffmpeg to generate a thumbnail. Unfortunately, ffmpeg does not fill in my provided buffer, even though the whole command execution is successful.

  I’m reading the video from a http request body :

  videoData, err := ioutil.ReadAll(r.Body)

  This is how I push it to ffmpeg :

  log.Print("Creating thumbnail..")
  
  
  
  width := 640
  
  height := 360
  
  log.Print("Size of the video: ", len(videoData))
  
  
  
  
  
  cmd := exec.Command("ffmpeg", "-i", "pipe:0", "-vframes", "1", "-s", fmt.Sprintf("%dx%d", width, height), "-f",  "singlejpeg", "-frame_size", fmt.Sprintf("%d", totalVideoBytes), "-")
  
  
  
  cmd.Stdin = bytes.NewReader(videoData)
  
  
  
  var imageBuffer bytes.Buffer
  
  cmd.Stdout = &imageBuffer
  
  err := cmd.Run()
  
  
  
  if err != nil {
  
      log.Panic("ERROR")
  
  }
  
  
  
  imageBytes := imageBuffer.Bytes()

  This is the error output :

  [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7ff05d002600]stream 0, offset 0x5ded : partial file

  pipe:0 : Invalid data found when processing input

  Finishing stream 0:0 without any data written to it.

  frame= 0 fps=0.0 q=0.0
  Lsize= 0kB time=-577014:32:22.77 bitrate= -0.0kbits/s speed=N/A
  video:0kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB
  muxing overhead : unknown

  Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

  Thanks a lot, any help is appreciated.

• avformat/utils : Stream specifier enhancement 2.

  13 avril 2018, par Bela Bodecs

  avformat/utils : Stream specifier enhancement 2.
  In some cases, mainly working with multiprogram mpeg-ts containers as
  
  input, it would be handy to select sub stream of a specific program by
  
  their metadata.
  
  This patch makes it possible to narrow the stream selection among
  
  streams of the specified program by stream metadata.
  Examples :
  
  p:601:m:language:hun  will select all sub streams of program with id 601
  
  where sub streams have metadata key named 'language' with value 'hun'.
  
  p:602:m:guide  will select all sub streams of program with id 602 where
  
  sub streams have metadata key named 'guide'.
