  • 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).

  • lavfi/drawtext : ignore final LF of textfile.

    30 novembre 2020, par Nicolas George
    lavfi/drawtext : ignore final LF of textfile.

    A standard text file ends with a final LF.
    
Without this change, it is interpreted as an empty final line,
    
and visible with the box option.
    
The current behavior can be achieved by actually having
    
an empty line at the end of the file.
    

    Fix trac ticket #7948.
