  • FFMPEG | add same effect with different settings several times to an input-file

    3 mai 2019, par Bamba675

    I’m trying to remove (for example) the greenscreen and the bluescreen of a video. To do this, I have to use FFMpeg.

    I already tried this one :

    ffmpeg -i background.mp4 -i greenbluefootage.mp4 -filter_complex "[1:v]chromakey=0x67FF00:0.1:0.1,chromakey=0x0061FF:0.1:0.1[aa];[0:v][aa] overlay" output.mp4

    The problem is, that just one color gets removed.
    I simply want to remove both colors (make them transparent) so the background can shine through.

  • Opencv VideoCapture always returns false on Heroku

    27 juin 2022, par Dacian Mujdar

    I'm using the following code to open a video stream :

    


    import cv2
video = cv2.VideoCapture()
video.open("some_m3u8_link")
success, image = video.read()


    


    However, even if the code works as intended locally, on Heroku success is always false.

    


    I'm using cedar-14 stack with the following buildpacks :

    


    


    heroku/python

    


    https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git

    


    


    (I tried several buildpack options for ffmpeg)

    


    Running ffmpeg --version on heroku instance will return ffmpeg version 4.0-static https://johnvansickle.com/ffmpeg/

    


    Is there any setting/configuration I missed in order to make it work on deployment ? Thank you !

    


    Later edit : I tried several links for "some_m3u8_link" including from twitch and other streaming services (including traffic streaming li
An example for reproducing :

    


    python -c "import cv2; video=cv2.VideoCapture(); video.open('https://hddn01.skylinewebcams.com/live.m3u8?a=5tm6kfqrhqbpblan9j5d4bmua4'); success, image = video.read(); print(success)"


    


    Returns True on local machine and False on Heroku.

  • ffmpeg carrierwave-video always returns "unknown encoder libfaac"

    17 juillet 2015, par olgash

    I can give ffmpeg videos to convert via command line, and it converts them happily, but when I ask it to convert things in rails, it returns "Unknown encoder libfaac" no matter the video I give it.

    I call it using this line :
    process encode_video : [:mp4, resolution : "640x480"]

    I’ve already spent hours trying to (unsuccessfully) compile ffmpeg with libfaac on Windows, but now it just seems ridiculous, because not everything I pass it is even aac. What’s going on ?
