  • capturing x11grab display from ffmpeg giveing "segmentation fault1 q=0.0"

    26 juin 2019, par user2369563

    In Debian 9, I am trying to record screen using ffmpeg over x11grab. it's working great but sometimes its give error as shown below.
Any idea what causing this ?

    



    exec error: Error: Command failed: ffmpeg -y  -f x11grab -s 1920x1080 -framerate 30 -i :1.0+0,0 -vsync 1 -c:v libx264 -preset ultrafast -crf 0 -pix_fmt yuv444p output.mkv

  • avformat/matroskaenc : Avoid seeking when writing level 1 elements

    20 avril 2019, par Andreas Rheinhardt
    avformat/matroskaenc : Avoid seeking when writing level 1 elements

    Up until now, the writing process for level 1 elements (those elements
    
for which CRC-32 elements are written by default) was this in case the
    
output was seekable : Write the EBML ID, write an "unkown length" EBML
    
number of the desired length, then write the element into a dynamic
    
buffer, then write the dynamic buffer (after possible calculation and
    
writing of the CRC-element), then seek back to the size element and
    
overwrite the unknown-size element with the real size. The seeking and
    
overwriting part has been eliminated by not writing the size initially.
