  • src/libFACL/stream_decoder.c : Fail safely to avoid a heap overflow.

    20 novembre 2014, par Erik de Castro Lopo
    src/libFACL/stream_decoder.c : Fail safely to avoid a heap overflow.

    A file provided by the reporters caused the stream decoder to write to
    
un-allocated heap space resulting in a segfault. The solution is to
    
error out (by returning false from read_residual_partitioned_rice_())
    
instead of trying to continue to decode.

    I want to overlay some video on the image frame and rotate it and output it as the resultant video. However the command is running successfully but it is producing some weird output video with both the top and bottom portion with black layer, but however the rotation of the video over the image is successful but the top and bottom portion are getting black.

  • Got black screen when recording screen by x11grab device

    30 janvier 2014, par shawnzhu

    I'm trying to record video from a firefox run by xvfb-run but it always output nothing in the video file except black screen.

    Here's what I did :

    start a firefox, open google.com :

    $ xvfb-run firefox https://google.com

    Then it will use the default display server number 99. I can see the display information by command xdpyinfo -display :99.

    A screenshot works very well by command :

    $ xwd -root -silent -display :99.0 | xwdtopnm |pnmtojpeg > screen.jpg

    Start using ffmpeg to record a video :

    $ ffmpeg -f x11grab -i :99.0 out.mpg

    When I play the video file out.mpg, there's black screen all the time.

    Is there any parameter I missed ?
