Description:
Trying to make rips from TV-records on DVD-R with dvdrip.
My old install (glibc 2.13-5, ffmpeg 25679-1, transcode 1.1.5-5) was working fine.
This new, fresh install does not: it throws an error at the end of pass 1


Additional info:
* package version(s)
glibc 2.14-6
ffmpeg 20110923-1
transcode 1.1.5-6
* config and/or log files etc.
dvdrip's logfile.txt:
...

Steps to reproduce (my usual procedure actually, can't try other combinations):
Using dvdrip: 2-pass encoding to ffmpeg/mpeg4 w/ frame range and w/o any filters.

Is it fixed with ffmpeg 20111003-1 ?
Comment by Fabien COUTANT (fcoutant) - Tuesday, 04 October 2011, 16:38 GMT
Do you mean the version from testing ? (I'm not using it in pacman.conf, so had to download it manually along with x264.)
And no, I still get the same error.
Comment by Fabien COUTANT (fcoutant) - Sunday, 29 January 2012, 16:15 GMT
FYI
Still no fix for this.
Since several versions it now crashes right upon start of transcoding.
Current versions: glibc 2.15-4 ffmpeg 20120127-1 transcode 1.1.7-3

Comment by Maik Freudenberg (mfreud) - Friday, 17 February 2012, 14:33 GMT
Just to share my findings: The new crash (not really a crash) results from some bugs in transcode. Using mpeg4 as codec, it always tries to load a ffmpeg preset 'medium' which is hardcoded in transcode. So it looks for a file $HOME/.ffmpeg/medium.ffpreset
If transcode doesn't find that file, it exits, freeing memory it hasn't yet allocated which results in the backtrace. If you create that file and leave it empty, another bug in transcode is triggered, and it segfaults. So just create $HOME/.ffmpeg/medium.ffpreset with a line starting with #, just a comment, to work around it.
The original bug, which started this thread, is still existent. Seems like an incompatibility between transcode and newer ffmpeg, but: ffmpeg-guys says: ask transcode and vice-versa. Needs some more debugging.
Workaroud: Disable glibs' mallock-check: export MALLOC_CHECK_=0 && dvdrip.

upstream report?
Comment by Greg (dolby) - Monday, 15 October 2012, 08:23 GMT
Still a problem?
Comment by Fabien COUTANT (fcoutant) - Thursday, 18 October 2012, 17:43 GMT
I didn't check, since I have fallen back to using an old Arch install for video encodings.
I will try to check latest versions (assuming you mean it's corrected in ffmpeg 1.0) next weekend.

Hi
Got some time to test an upgrade: transcode 1.1.7-6 with ffmpeg 1:1.0-1 (also tested 1:0.11.1-1).
Now I think it's worse, I get this instead of a stacktrace:
transcode: symbol lookup error: /usr/lib/transcode/export_ffmpeg.so: undefined symbol: avcodec_thread_init
Also, there's no log of any .ffpreset file missing, now I've got
export_ffmpeg.so warning: Error opening configuration file ./ffmpeg.cfg: No such file or directory
I don't know whether this voids the trick from Maik (didn't test before upgrade).

Try transcode-1.1.7-12 in [testing]. I've added new and updated ffmpeg patches which seem to include a fix for this issue. Please test and let me know if it works.
