  • FFMPEG "Segmentation fault" with stream source and watermark

    4 mars 2020, par Magikey

    I use release : 4.2.2 (static) from "https://johnvansickle.com/ffmpeg/"

    Final code will be on "Amazon AWS lambda"

    Goal : use a url stream and add watermak

    Link to video : ​https://feoval.fr/519.mp4

    Link to Watermak : ​https://feoval.fr/watermark.png

    ./ffmpeg -i "https://feoval.fr/519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

    return "Segmentation fault"

    I have the same error on my computer and on AWS Lambda server

    ./ffmpeg -i "https://feoval.fr/519.mp4" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

    work (but not watermak)

    ./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

    work (but not with stream)

    Thanks you very much !

  • Ffmpeg video length is not as expected

    29 juin 2016, par Karnivaurus

    I have a folder containing 500 images, of that format image0.png, image1.png, ..., image499.png. I want to use ffmpeg to convert these images to a video with a frame rate of 50. This should meant that the total video duration is 10 seconds (= 500 / 50).

    To do this, I used the following command :

    ffmpeg -r 50 -f image2 -i image%1d.png -vcodec libx264 -crf 15 -pix_fmt yuv420p video.mp4

    However, the video which was created, had a duration of 2.5 seconds. Otherwise, the video displays the images correctly, and runs from the beginning to the end as expected.

    Why is the video length not as I would have expected ?


    The full output from the console is :
