  • ffmpeg create video from a sequence of images

    1er février 2021, par t97

    I have a sequence of images as follow :

    


    img_1.png
img_2.png
img_3.png
...
img_1799.png


    


    From the documentation I run this command

    


    ffmpeg -f image2 -pattern_type glob -framerate 24 -i 'img_*.png' test-size.mp4


    


    but it doesn't generate the video correctly. I also looked online but wasn't able to find the correct command.

    


    what's the command to run to merge all the images so the output video is 30s long at 24 fps ?

    


  • Got incorrect audio duration from ffmpeg

    8 septembre 2021, par Remeraze

    I used an ffmpeg command to export parts of an audio clip :

    


    ffmpeg -i {path} -acodec copy -ss {start_time} -to {end_time} {output_path}


    


    Unfortunately, this has the side effect of not changing the time duration in the file's details section, making many programs I use think the time of the cut audio files is much more than it really is.

    


    Is there a way to either make ffmpeg change the duration, or find a command in python that can change an audio file's "length" stat so I can do it manually ? I couldn't find any way online.

    


    Thanks.

    


  • any solution to Matlab VideoReader on compressed avi file on Mac ?

    3 décembre 2016, par Peng JL-Zhulin

    I am working on some video gamma correction. And I used some sample avi uncompressed clips from online, everything works just fine.
    But once I try to use our own .avi video 1280x800 20 second about 400mb, Matlab can not read file through ’VideoReader’.

    I’m really sure the problem is that my video is compressed avi. And I have tried the following to solve it :

    1. some say in mac os, download gstreamer 0.10 may help. I did, but problem remained.
    2. i tried to use ffmpeg to convert the compressed avi to uncompressed avi (i dont think i am supposed to do this tho). but the new uncompressed video became a mess.

    So, I was thinking, when working on compressed avi file in MATLAB in mac, is there a godd routine that people follow ?

    Thanks a lot.
