Package: lives Version: 2.4.0~ds0-1+b1 Severity: normal Some of my clips fail to encode (with the x264 encoder) because the generated audiodump.wav is empty (44 bytes long, which I expect is the wav header, no actual data).
I've traced that to smogrify being called with a negative value for "end of audio". For example with arguments: save 483408242 25.000 /home/master/Videos/FOO.mp4 1 54931 44100 2 16 1 0.0000 -1698.4000 I first thought of an integer overflow, because: - a clip of 1200 seconds works - a clip of 2197.24 seconds fails So I thought maybe overflow at 2048 (11 bits?), but then I tried a clip of 2000 seconds, and then smogrify is called with: save 927025633 25.000 /home/master/Videos/FOO.mp4 1 50000 0 0 0 1 -nan -nan This seems to be linked to the end of the to-be-encoded selection audio being more than some specific value of seconds after the beginning of the clip seconds... Further observations: - 1800s works - 1920s works - 1999.96s doesn't work - 1999s doesn't work - 1998.96s doesn't work - 1997.28s doesn't work - 1960s doesn't work - 1940s works - 1950s doesn't work - 1946s works - 1948s doesn't work - 1947s works - 1947.40s works - 1947.80s doesn't work - 1947.60s works - 1947.68s works - 1947.76s works And that's it... 1947.80s is 48695 frames and 1947.76s is 48694 frames. That's where the overflow/NaN starts to happen. -- System Information: Debian Release: 8.2 APT prefers stable APT policy: (500, 'stable'), (400, 'testing'), (200, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.16.0-4-amd64 (SMP w/8 CPU cores) Locale: LANG=fr_LU.UTF-8, LC_CTYPE=fr_LU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/bash Init: systemd (via /run/systemd/system) Versions of packages lives depends on: ii frei0r-plugins 1.4-3+b1 ii imagemagick 8:6.8.9.9-5 ii libasound2 1.0.28-1 ii libatk1.0-0 2.18.0-1 ii libavc1394-0 0.5.4-2 ii libavutil-ffmpeg54 7:2.8.2-1 ii libc6 2.19-18+deb8u1 ii libcairo-gobject2 1.14.0-2.1 ii libcairo2 1.14.0-2.1 ii libgdk-pixbuf2.0-0 2.31.1-2+deb8u3 ii libglib2.0-0 2.46.2-1 ii libgtk-3-0 3.18.5-1 ii libjack-jackd2-0 [libjack-0.116] 1.9.10+20140719git3eb0ae6a~dfsg-2 ii libmjpegutils-2.1-0 1:2.1.0+debian-3 ii libpango-1.0-0 1.38.1-1 ii libpangocairo-1.0-0 1.38.1-1 ii libpng12-0 1.2.50-2+deb8u1 ii libpulse0 5.0-13 ii libraw1394-11 2.1.0-3 ii libswscale-ffmpeg3 7:2.8.2-1 ii libunicap2 0.9.12-2 ii libweed0 2.4.0~ds0-1+b1 ii libx11-6 2:1.6.2-3 ii lives-data 2.4.0~ds0-1 ii lives-plugins 2.4.0~ds0-1+b1 ii mplayer2 [mplayer] 2.0-728-g2c378c7-4+b1 ii ogmtools 1:1.5-3+b1 ii perl 5.20.2-3+deb8u1 ii procps 2:3.3.9-9 ii python 2.7.9-1 ii sox 14.4.1-5 Versions of packages lives recommends: ii dvgrab 3.5-2+b2 ii icedax 9:1.1.11-3 ii libogg0 1.3.2-1 ii libtheora-bin 1.1.1+dfsg.1-6 ii libtheora0 1.1.1+dfsg.1-7 ii mencoder 2:1.2-1 ii mkvtoolnix 8.5.2-1 ii pulseaudio 5.0-13 ii x11-utils 7.7+2 ii youtube-dl 2015.11.10-1 Versions of packages lives suggests: ii libdv-bin 1.0.0-6 ii mjpegtools 1:2.1.0+debian-3 -- no debconf information _______________________________________________ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/pkg-multimedia-maintainers
