           Summary: avconv does not respond to sigint under debian
                    unstable when compiled with configure option
                    "--enable-libopencv"
           Product: Libav
           Version: git HEAD
          Platform: X86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: Normal
         Component: utilities
        AssignedTo: bugzilla at libav.org
        ReportedBy: jonathan-vola at hotmail.com


avconv doesn't respond to sigint (via ctrl+c terminal shortcut or via kill
command) when the following command is used under debian unstable:

    avconv -f pulse -i default -acodec copy out.avi

It fails under terminal emulators and TTYs. Killing the program with SIGKILL is
not really possible as this corrupts the video file it's supposed to make.

Running under valgrind it suddenly does respond to sigint despite not showing
any errors.

Configured with:

    ./configure --arch=amd64 --enable-pthreads --enable-runtime-cpudetect
--libdir=/usr/lib/x86_64-linux-gnu --enable-bzlib --enable-libdc1394
--enable-frei0r --enable-gnutls --enable-libgsm --enable-libmp3lame
--enable-librtmp --enable-libopencv --enable-libopenjpeg --enable-libopus
--enable-libpulse --enable-libschroedinger --enable-libspeex --enable-libtheora
--enable-vaapi --enable-vdpau --enable-libvorbis --enable-libvpx --enable-zlib
--enable-gpl --enable-swscale --enable-libcdio --enable-x11grab
--enable-libx264 --enable-libxvid --shlibdir=/usr/lib/x86_64-linux-gnu
--enable-shared --disable-static --prefix=/home/j/projects/libavbuild

I have however bisected the configure flags to find that the offending option
is: --enable-libopencv

Without that option avconv runs as expected.
