Bug Description

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)

I'll concur with this. Whether or not the problem is in transcode or ffmpeg is a good question; but wherever it is, it renders k3b inoperative.

Attached is my log after creating "~/.ffmpeg/medium.ffpreset". I think this happens on the second pass.

The details in the ArchLinux bug about MALLOC_CHECK_ seemed like it was going to work, but then is crashed out again. I'll post a send log file.

This bug affects me too, 64 bit Kubuntu 14.04.
I found relatives:
Bug reported in debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=697558
which points to the bug at transcode, where a patch is proposed:
https://bitbucket.org/france/transcode-tcforge/issue/4/segfault-at-end-of-pass-1-ffmpeg-mpeg4

Anybody here capable of verifying if this fixes the issue?

It still has this bug.

I worked around it by using k3b to Copy Disc to the hard drive as an iso.
Then mounted the iso and used HardBrake to rip the contents.

I rebuilt k3b (https://bugs.launchpad.net/ubuntu/+source/k3b/+bug/1686089) and transcode with this patch for Ubuntu 17.04, and that resolved those particular problems.
The k3b bug is a very new one, however this one is from 2014 so I'm wondering that patch hasn't made it into packages yet.

Got this same error with Ubuntu 17.10 and k3b.

The k3b debug window shows

...

*** Error in `/usr/bin/transcode': munmap_chunk(): invalid pointer: 0x00007efd97e43f3a ***

------------------

However: If I run that same command in bash it creates an ok file. It appears that this error message from transcode causes k3b to delete the file even though it appears the file was created ok by transcode.
