Public bug reported: In k3b you can rip DVD's. There are two filetypes you can use: MPEG4 (FFMPEG) and XviD. The latter one works, the first NOT.
1) The first error it receives is this: *** glibc detected *** /usr/bin/transcode: munmap_chunk(): invalid pointer: 0x00007fb245badc25 *** > See also backtrace 1 below 2) After advice from https://bugs.archlinux.org/task/26208 I created ~/.ffmpeg/medium.ffpreset with one dummy line starting with #. The video is starting to encode, but there is another error: *** glibc detected *** /usr/bin/transcode: free(): invalid pointer: 0x00007f5e1e16879a *** > See also backtrace 2 below 3) When I try to start (on the command line) one of the transcode commands I've found at the end of the log file: /usr/bin/transcode --nice 19 --log_no_color --progress_meter 2 --progress_rate 272 -i /dev/sr0 -x dvd -T 1,-1,1 -a 0 -j 0,0,0,0 -R 1,/tmp/kde-jeroen/k3b_0.log -y ffmpeg,null -o /dev/null -F mpeg4 -w 1200 -Z 768x576 ... it started to encode, but I receives this: "Segmentatiefout (geheugendump gemaakt)" < Dutch for Segmentation fault (memory/core dumped) Backtrace 1) [export_ffmpeg.so] Using FFMPEG codec 'mpeg4' (FourCC 'DIVX', MPEG4 compliant video).
