• moviepy ruining video after combining them

  1er juin 2020, par jjakeryan

  I'm trying to make a program that downloads videos from TikTok and combines all the separate videos into one .mp4 file and moves the final video to a folder on my desktop. I've been able to make it download all the videos and when I watch the separate videos they play fine however when I combine the videos some of the videos are messed up and look like this but the audio is fine.

  



  #slecting all .mp4 files
    video_files = glob.iglob("*.mp4")

    print(video_files)
    clips = []

    for clip in video_files:  # For each mp4 file name
        clips.append(VideoFileClip(clip))  # Store them as a VideoFileClip and add to the clips list

    today = date.today()

    final = concatenate_videoclips(clips)  # Concatenate the VideoFileClips
    final.write_videofile(f"{today}.mp4", codec="libx264")


#moving completed video to folder on desktop
    shutil.move(f'{today}.mp4', '/Users/jacobmarrandio/Desktop/done_videos/')


  



  thanks for any help

  


• How to stream video and audio to a virtual camera (simultaneously) and a virtual microphone, using ffmpeg ?

  26 janvier 2023, par Alex Delmero

  I created a virtual camera using the commands
modprobe v4l2loopback card_label="My Fake Webcam" exclusive_caps=1

  


  Passing video from a file to a virtual camera works for me on command

  


  ffmpeg -stream_loop -1 -re -i /root/Downloads/test.mp4 -vcodec rawvideo -threads 0 -f v4l2 /dev/video0

  


  I need to simultaneously transfer audio from the same file along with the video.
How to do it ?

  


  I have read the question already asked
https://stackoverflow.com/questions/61990828/how-to-redirect-an-audio-stream-to-a-virtual-pulseaudio-microphone-with-ffmpeg

  


  And try command
ffmpeg -stream_loop -1 -re -i /home/alex/test.mp4 -threads 0 -f v4l2 /dev/video0 & PULSE_SINK=virtual_speaker ffmpeg -i /home/alex/test.mp4 -f pulse "stream name"

  


  But I only get audio, no video...

  


• Download TS files from video stream

  13 avril 2017, par Nicky Smits

  Videos on most sites make use of progressive downloading, which means that the video is downloaded to my computer, and easy to trace. There are lots of extensions out there to do this, and even in the dev-tools this is easily done.

  On certain websites videos are streamed. which means that we do no just download 1 file, we download lots of small packages. In the dev-tools these packages can be traced. The website I’m interested in is : http://www.rtlxl.nl/# !/goede-tijden-slechte-tijden-10821/c8e2bff7-5a5c-45cb-be2b-4b3b3e866ffb.

  -The packages have a .TS extension.

  -Packages can be saved by copying the url of the request

  -I can not play these files.

  I must have done something wrong, or I’m missing something. I want to know what I am doing wrong. I want to create a chrome extension for personal use which captures the urls of all the packages. when I have all the urls I want to pass them on to a php scripts which downloads them and uses ffmpeg to paste them into a mp4 file.

  Please help me get the packages.
