  • 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).

  • 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.

  • Convert Videos with FFMPEG to PowerPoint 2016 compatible video format [closed]

    11 septembre 2020, par Sebastian S.

    I am trying to convert a bunch of videos to a video format that is natively supported by PowerPoint 2013/2016 on a Windows 7 system.

    


    Microsoft recommends on their website mp4 with h264 and aac.

    


    Video and audio file formats supported in PowerPoint

    


    


    In PowerPoint 2013 and later, and in PowerPoint 2016 for Mac, for the best video playback experience, we recommend that you use .mp4 files encoded with H.264 video (a.k.a. MPEG-4 AVC) and AAC audio. In PowerPoint 2010, we recommend that you use .wmv files.

    


    


    


    We recommend using .m4a files encoded with AAC audio. In PowerPoint 2010, we recommend that you use .wav or .wma files.

    


    


    Audio is not important for me.
I tried to convert my videos with ffmpeg using the following options :

    


    ffmpeg -i Input.avi -c:v libx264 -preset slow -crf 22 -c:a copy Output.mp4


    


    However I cannot import the video to PowerPoint 2016 (32 or 64bit, I tried both). I always get a missing codec error.

    


    PPT Error when including video files

    


    Has anyone successfully encoded videos to a natively supported PowerPoint video format (on Windows) ?
