• Socket code Python code at the end influences code in the beginning

  21 décembre 2019, par Samy Smart

  So basically i am trying to do the following things : Client sends project file, Server receives Project file, Server generates Video file, Server sends video File, Client receives Video File. Everything works up until sending the Video back. The Thing is when i include my code for sending the Video, not even the Things that worked before work anymore.
  The commented code in the code is the code that should send the Video back

  Client :

  import socket
  
  
  
  s = socket.socket()
  
  ip = socket.gethostname()
  
  file = "testae.aep"
  
  s.connect((ip, 1234))
  
  
  
  f = open(file, "rb")
  
  txt = f.read(1024)
  
  while txt:
  
      s.send(txt)
  
      print(f"Sending... {txt}")
  
      txt = f.read(1024)
  
  f.close()
  
  #f2 = open("final_output.mp4", "wb")
  
  #txt2 = s.recv(1024)
  
  #while txt2:
  
  #    f2.write(txt2)
  
  #    txt2 = s.recv(1024)
  
  #f2.close()
  
  print("received final output")
  
  s.close()

  Server :

  import os
  
  import socket
  
  
  
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  
  s.bind((socket.gethostname(), 1234))
  
  counter = 0
  
  s.listen(5)
  
  aerpath = "C:/aerender.lnk"
  
  ffmpegpath = '"C:/Program Files/ffmpeg/bin/ffmpeg.exe"'
  
  
  
  while True:
  
      c, addr = s.accept()
  
      print("Client Connected")
  
      print(addr)
  
      f = open(f"ae_render_file{counter}.aep", "wb")
  
      txt = c.recv(1024)
  
      while txt:
  
          f.write(txt)
  
          print(f"Receiving... {txt}")
  
          txt = c.recv(1024)
  
      print("Out of WHILE")
  
      f.close()
  
      print("received file")
  
      os.system(aerpath + " -project " + f"C:/Users/weilu/PycharmProjects/localAERF/ae_render_file{counter}.aep "
  
                + '-comp "Comp 1" ' + f"-output C:/Users/weilu/PycharmProjects/localAERF/output/output{counter}")
  
      os.system(ffmpegpath + " -i " + f"output/output{counter}.avi -f mp4 -vcodec libx264 -preset slow -profile:v main "
  
                                      f"-pix_fmt yuv420p -acodec aac -hide_banner output/outputr{counter}.mp4")
  
      #f2 = open(f"output/outputr{counter}.mp4","rb")
  
      #txt2 = f2.read(1024)
  
      #while txt2:
  
      #    c.send(txt2)
  
      #    print("Sending...")
  
      #    txt2 = f.read(1024)
  
      #f2.close()
  
      c.close()
  
      counter += 1

• Media Type Unrecognized with FFMPEG file generated

  2 août 2016, par pirmax

  I have an upload problem with the Twitter API.
  The problem is caused by codecs I think.

  I use FFMPEG to concatenate an audio file and an image, so to build a 30-second video to a file not exceeding in the 1MB.

  Here is the code that allows me to build this file and then upload the video via the Twitter API :

      var convert = function(image, audio, output) {
  
      var proc = ffmpeg(image)
  
      .loop(30)
  
      .addInput(audio)
  
      .format('mp4')
  
      .videoBitrate('1024k')
  
      .videoCodec('mpeg4')
  
      .size('640x640')
  
      .audioBitrate('128k')
  
      .audioChannels(2)
  
      .audioCodec('libfaac')
  
      .on('end', function() {
  
          console.log(output);
  
          fs.readFile(output, function(err, base64data) {
  
              client.post('media/upload', { media: base64data }, function (error, media, response) {
  
                  console.log(media);
  
              });
  
          });
  
      })
  
      .on('error', function(err) {
  
          console.log('an error happened: ' + err.message);
  
      })
  
      .save(output);
  
  };

  Each upload, I get the following message : unrecognized media type

  { request: '/1.1/media/upload.json',
  
    error: 'media type unrecognized.' }

  Could you help me please ? Thanks !

• ffmpeg - How to set MIME-type ? [migrated]

  22 octobre 2012, par sasa

  I'm trying to set the proper MIME-type for an AAC file, but this command does not work :

  ffmpeg -i rain.mp3 -metadata mime-type="audio/aac" rainmp3toaac.aac

  but, actualy audio/x-hx-aac-adts is set.

  So, how I can force another MIME-type ?
