  • gdb not stopping at even trivial breakpoints

    18 novembre 2015, par baruch

    I am trying to debug ffplay (a debug build) compiled using mingw-w64 on msys2 on Windows 7 64bit. I tried setting breakpoints using gdb, and they seem to be set fine, but the program does not stop. So i tried issuing start, and again it didn’t stop. I tried manually setting a breakpoint at main, but it still didn’t stop. I verified that main is found, and it is. Here is a portion of the session. Any explanation what might cause this ?

  • What ffmpeg filters can I use to achieve shrinking a video and keeping original aspect ratio ?

    3 août 2020, par sivano

    I am trying to do some specific video editing with ffmpeg and am lacking the correct terminology to describe it (and thus read online how to achieve it). Can someone help describe this using standard (ffmpeg/video editing) terminology ?

    


    The below describes it verbosely, and you can see it visually at the end (this was done manually for one image).

    


    I have a video with aspect ratio 1280x720. At some point in the video, I want to shrink the video diagonally (i.e. maintaining aspect ratio) so that it only takes up half the original width (i.e. 640) and then pad what is left with black. The purpose of this is to then overlay some other image on the left hand of the modified video.
