  • How to add watermark to some videos using ffmpeg ? Random images for watermark. The images should resize resolution according to video quality [duplicate]

    27 mars 2021, par Abir Hasan

    I have many videos in different quality/resolution. I want to add random image to the videos using ffmpeg. The images should resize image resolution according to video resolution. The image should be at top left corner and it should be very small. It should be same as YouTube Videos Branding Watermark.

    


    Currently I am resizing image using Pillow module to 100x100. But in some videos which are in less quality, the 100x100 watermark getting bigger.

    


    What is the solution ?

  • Trying to scale a webm video to 50% of its resolution using FFMPEG but keep getting an error (video has transparency btw)

    6 février 2021, par DistantDigit

    I'm trying to scale down a webm video with transparency using this line of commands (based off of an answer in this stackoverflow question @ How to keep transparency when scale webm file with ffmpeg) :

    


    ffmpeg -c:v libvpx -i in.webm -c:v libvpx -vf scale=400:416 -auto-alt-ref 0 out.webm

    


    but I keep getting errors (for example) :

    


    [libvpx @ 00000128eb6123c0] Invalid sync code 310042.
[libvpx @ 00000128eb6123c0] Failed to decode frame: Bitstream not supported by this decoder
