• 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

• Revision 9068bce4e7 : Put iterative motion search under speed control Enable iterative motion search

  3 juin 2013, par Jingning Han

  Changed Paths :
   Modify /vp9/encoder/vp9_rdopt.c

  
  
  Put iterative motion search under speed control

  Enable iterative motion search for compound inter-inter prediction
  of block sizes 4x4/4x8/8x4 only when best coding quality is selected.
  The iterative motion search provides about 0.1% gains for derf and
  stdhd at this point, at the expense of longer runtime.

• problem with creating a robot voice with flutterFFmpeg

  28 février 2021, par Sadiq Samaila

  so here is the code I ran

  


                        String commandToExecute =
                      "-i $aud -filter_complex 'afftfilt=real='hypot(re,im)*sin(0)':imag='hypot(re,im)*cos(0)':win_size=512:overlap=0.75' " +
                          outputPath;
   
                  _flutterFFmpeg.execute(commandToExecute).then((rc) => print(
                      "FFmpeg process exited with rc $rc $appDocumentDir"));


  


  and I got this error

  


  E/mobile-ffmpeg( 5493): [AVFilterGraph @ 0x7ce619159800] No such filter: 'im)*sin(0):imag'
E/mobile-ffmpeg( 5493): Error initializing complex filters.
E/mobile-ffmpeg( 5493): Invalid argument
D/flutter-ffmpeg( 5493): FFmpeg exited with rc: 1


  


  I tried changing all single quote(') to double quote(") in the command but it did not work.
