  • 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.

  • Threads creating process in infinite loop

    10 décembre 2013, par bhupinder

    In my application a thread runs while(1){} in it so thread terminates when my app is terminated by user.

    Is it safe to do like this ? I am using while(1){} because my app continuously monitors devices on system.

    After some time I am getting "(R6016) not enough space for thread data" on ffmpeg.

    I read this but did not get solution of my problem :

    http://support.microsoft.com/kb/126709

    Thread description :
    Thread uses ffmpeg and handle utility (http://technet.microsoft.com/en-us/sysinternals/bb896655.aspx). within while(1){} loop.

    ffmpeg and handle is running through QProcess which I am deleting after process ends.

    while(1){} loop waits for 5 seconds using
    msleep(5000).

  • Convert from webm to gif using FFMPEG with minimal loss in quality

    27 novembre 2017, par Neo Herakles

    so I want to convert all my webm files to gif but the quality degraded incredibly, there’s some barely visible lines along the picture, tried using crf to improve it but it doesn’t, could you help me ? Here’s my code :

    @echo off
    
setlocal
    
for %%G in ("%~dp0\webm\*.webm") do (
    
    ffmpeg -i "%%G" -pix_fmt rgb24 -crf 17 "%%G.gif"
    
    )
    
)
    
endlocal
    
pause

    Also, could you instruct me in a way in which I can remove the .webm from the output filename ? it outputs as "(file name).webm.gif"
