  • FFmpeg film grain

    21 août 2019, par Some1Else

    I want to add a film grain effect using FFMPEG if possible.

    Taking a nice clean computer rendered scene and filter for a gritty black and white 16mm film look. As an example something like Clerks https://www.youtube.com/watch?v=Mlfn5n-E2WE

    According to Simulating TV noise Ishould be able to use the following filter

    -filter_complex "geq=random(1)*255:128:128;aevalsrc=-2+random(0)"

    but when I add it to my ffmpeg command

    ffmpeg.exe -framerate 30 -i XYZ%05d.PNG -vf format=yuv420p -dst_range 1 -color_range 2 -c:v libxvid -vtag xvid -q:v 1 -y OUTPUT.AVI

    so the command is now

    ffmpeg.exe -framerate 30 -i XYZ%05d.PNG -vf format=yuv420p -dst_range 1 -color_range 2 -c:v libxvid -vtag xvid -q:v 1 -y -filter_complex "geq=random(1)*255:128:128;aevalsrc=-2+random(0)" OUTPUT.AVI

    I get the message

    Filtergraph ’format=yuv420p’ was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph.
    - vf/-af/-filter and -filter_complex cannot be used together for the same stream.

    How can I change my ffmpeg command line so the grain filter works ? Additionally, can I add a slight blur too ? The old 16mm looks more like blurred then grainy.

    Thanks for any tips.

  • Extract just the audio link from a youtube video without converting

    27 janvier, par MR-4O4

    I know there are hundreds of sites to convert youtube video to mp3. Most of them do it by first downloading the video and then converting it to mp3(or any other audio format) on their server using youtube-dl, ffmpeg or similar programs.

    



    What I want to know is, is there any way I can just extract the audio link for any youtube video ? I don't know if it's possible but I saw a couple of websites doing it .

    



    First Website : Openaisearch.com
This website simply gives a download link for the audio(getting it from youtube videos). I searched for a song and saw the download url, it looked something like this :

    



    https://redirector.googlevideo.com/videoplayback?source=youtube&requiressl=yes&clen=3814013&upn=dzwY9aUVYME&lmt=1469875393441562&expire=1484854959&mime=audio%2Fmp4&nh=IgpwcjAxLnNlYTA5Kg01Mi45NS4yMTYuMTAy&itag=140........... 


    



    I believe that this is not done by first downloading and converting the video to audio format(Correct me if I am wrong).
Although the file which gets downloaded after using this link is without any extension, but adding ".m4a" at the end of downloaded file does the work.

    



    Second Website : http://keepvid.com/ ?url=https ://www.youtube.com/watch?v=PT2_F-1esPk

    



    Again similar website with similar audio link. You can check by visiting the URL and see link of audio files.

    



    Any idea how these websites get that "googlevideo.com" link ? Do they scrap the youtube video links or something ?

    



    Thanks.
