• ffmpeg : Don't require a known device to pass a frames context to an encoder

  29 avril 2020, par Mark Thompson

  ffmpeg : Don't require a known device to pass a frames context to an encoder
  The previous code here did not handle passing a frames context when
  
  ffmpeg itself did not know about the device it came from (for example,
  
  because it was created by device derivation inside a filter graph), which
  
  would break encoders requiring that input.  Fix that by checking for HW
  
  frames and device context methods independently, and prefer to use a
  
  frames context method if possible.  At the same time, revert the encoding
  
  additions to the device matching function because the additional
  
  complexity was not relevant to decoding.
  Also fixes #8637, which is the same case but with the device creation
  
  hidden in the ad-hoc libmfx setup code.

• Revision 25f22d2e0b : In realtime mode enforce one pass with 0 lag vpxenc level changes to enforce on

  14 février 2014, par Deb Mukherjee

  Changed Paths :
   Modify /vpxenc.c

  
  
  In realtime mode enforce one pass with 0 lag

  vpxenc level changes to enforce one pass encoding with 0
  lag_in_frames when —rt mode is on.

• 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
