  • Taking a high resolution picture with FFMPEG and Webcam

    13 mai 2016, par user2088176

    I have a Microsoft LifeCam VX-3000 and I want to capture a single image from this video source.

    I have tried DirectShow :

    ffmpeg -f dshow -video_size 1280x960 -i video="Microsoft LifeCam VX-3000" -vframes 1 file.jpg
    

    
[dshow @ 01D69340] Could not set video options

    and
    Microsoft WDM Image Capture :

    ffmpeg -f vfwcap -video_size 1280x960 -i video="Microsoft LifeCam VX-3000" -vframes 1 file.jpg
    

    
[vfwcap @ 01D79340] Could not set Video Format.

    If I lower the video size to 640x480, it works, but every sites tells me that 640x480 is the maximum video resolution, but the still picture maximum resolution is 1280x960. Like here

    I would like to capture the image at the highest resolution possible. Is there a way to do it with FFMPEG ? What command-line options should I give it ?

    Thank you very much.

  • FFMPEG Converting a bunch of PNG images to a video

    7 février 2017, par user2419553

    I have a folder full of 600 .png’s that I’d like to convert to a video using FFMPEG. The .png filenames are as follows :

    f_001.png

    f_002.png

    f_003.png

    ...

    f_600.png

    I’ve been trying to use the following command to try to convert them :

    ffmpeg -r 10 -i root/Record/frames/f_%03d.png -vcodec libx264 -crf 0 /root/Record/"$(date +"%Y_%m_%d %I.%M %p")".mkv

    But I keep getting the error :

    Could find no file with path 'root/Record/frames/f_%03d.png' and index in the range 0-4
    
root/Record/frames/f_%03d.png: No such file or directory
