• Revision 2901bf2d00 : Reducing the number of recursive calls. Both decode_modes_sb and decode_modes_b

  30 octobre 2013, par Dmitry Kovalev

  Changed Paths :
   Modify /vp9/decoder/vp9_decodframe.c

  
  
  Reducing the number of recursive calls.

  Both decode_modes_sb and decode_modes_b had conditions to immediately
  return at the beginning. Eliminating these conditions here and calling
  these functions only to do a real work. Also unrolling loop for
  PARTITION_SPLIT.

• Video - ffmpeg wrong frame number when merging mkv files

  9 juin 2014, par communications

  im trying to join several mkv files together with ffmpeg.

  they all have the same encoding settings.

  i think ffmpeg joins the files, because the filesize of the resulting file has the size of all others combined

  BUT when i open the file, only the number of frames of the last part are shown, so i guess its a problem in the header, where is says how long the video is...

  How can i fix that ?

  Heres the command i use :

  ffmpeg -i "concat:100frames_part0.mkv|100frames_part1.mkv|100frames_part3.mkv" -c copy 100frames.mkv

• 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
