  • PNG to webm - mask not synchronized

    4 juin 2018, par Saiffyros

    I’m using ffmpeg to convert 230 pngs to webm format.The quality was not good, so, I added -lossless 1 to the command. But, now mask is not synchronized.

    It’s like this : https://image.ibb.co/niEOAy/screenshot0002.png

    Here are the commands I’m using :

    ffmpeg -framerate 30 -i epsilon-idle_%3d.png -lossless 1 epsilon-idle.webm
    

    
ffmpeg -r 30 -i epsilon-idle_%3d.png -lossless 1 -filter:v alphaextract epsilon-idle_mask.webm

  • Mask an Image over Video in Android

    19 octobre 2018, par Kiran Maniya

    enter image description here

    See the Example image shown above. Y is a video having chrome key color inside it(here RED Color). X is an image to be clipped on video chrome key and Output is shown in the image.
    Now the problem is, the chrome key (RED Color part) is moving a bit while playing so, is there any way to clip and mask an image on video directly ?

    Right now I’m using

    1. Platform : Android
    2. Library : FFmpeg
    3. File Types : Video(mp4) and Image(png)
