  fftools/ffmpeg_filter : move filtering to a separate thread
  As previously for decoding, this is merely "scaffolding" for moving to a
  
  fully threaded architecture and does not yet make filtering truly
  
  parallel - the main thread will currently wait for the filtering thread
  
  to finish its work before continuing. That will change in future commits
  
  after encoders are also moved to threads and a thread-aware scheduler is
  
  added.

  fftools/ffmpeg_enc : move encoding to a separate thread
  As for the analogous decoding change, this is only a preparatory step to
  
  a fully threaded architecture and does not yet make encoding truly
  
  parallel. The main thread will currently submit a frame and wait until
  
  it has been fully processed by the encoder before moving on. That will
  
  change in future commits after filters are moved to threads and a
  
  thread-aware scheduler is added.
  This code suffers from a known issue -  if an encoder with a sync queue
  
  receives EOF it will terminate after processing everything it currently
  
  has, even though the sync queue might still be triggered by other
  
  threads. That will be fixed in following commits.

• Capture xvfb stream from docker container using webRTC [closed]

  5 septembre 2023, par HIMANSHU SAHU

  I have a windows game .exe file and running the game inside a docker container (In EC2 linux VM) using xvfb version of X server. Now I want to Capture X server stream from docker container to my local system using webRTC. What should I do for the same ?

  


  Here's my Dockerfile :

  


  FROM ubuntu:22.04

  


  #Specify a workdir, to better organize your files inside the container.

  


  WORKDIR /app

  


  #Update package lists and install required packages

  


  RUN apt-get update
RUN apt-get install -y wget software-properties-common gnupg2 winbind xvfb
RUN apt-get -qq update -y && apt-get -qq install -y —no-install-recommends \

  As of now I'm capturing the xserver stream using ffmpeg and storing the same in .mp4 file. Now I want to play the game on my local machine by using webRTC for connection and streaming.

  


  I have run the .exe in linux using wine and xvfb server and captured the stream using ffmpeg and stored in a .mp4 file.
