Public bug reported: Came across this problem using OGMRip in ubuntu 13.04. The rip broke down at the last step: merging the video-, audio- and chapters-files into a complete mp4. Tried the same rip in Ubuntu 12.04. Same result. Which was odd, because OGMRip has always worked fine for me in 12.04 in the past.
Submitted a post, including a full log-file, about this failure at the developper's web-page at sourceforge. Find it here: http://sourceforge.net/p/ogmrip/discussion/258034/thread/dc196114/ I then started experimenting with MP4Box as a stand-alone ap, to see if I could narrow down the source of the failure: Thus I interrogated / re-packaged one of my old mp4s with MP4Box. To get a record of the material in the source-file I did: azed@azed-N110:~/Desktop$ MP4Box -info LesTroyensAct2.mp4 * Movie Info * Timescale 600 - Duration 00:25:21.898 2 track(s) Fragmented File: no File suitable for progressive download (moov before mdat) File Brand mp42 - version 0 Created: GMT Sat Apr 20 20:39:29 2013 File has root IOD (9 bytes) Scene PL 0xff - Graphics PL 0xff - OD PL 0xff Visual PL: AVC/H264 Profile (0x15) Audio PL: AAC Profile @ Level 2 (0x29) No streams included in root OD Chapters: Chapter #1 - 00:00:00.000 - "Act 2, Tableau 1.1 Sc�ne et R�citatif - "O lumi�re de Troie !"

No problems, thus far. [The omissions in the chapter- headings, above, can be ignored (I assume), as being caused by limitations on the characters available to the terminal] Re-packaged this mp4, without including a chapters file, with: azed@azed-N110:~/Desktop$ MP4Box -fps 30000/1001 -add LesTroyensAct2.mp4#video -add LesTroyensAct2.mp4#audio ../LesTroyensAct2.mp4 IsoMedia import LesTroyensAct2.mp4 - track ID 201 - Video (size 608 x 336) Warning: track ID 201 has references to a track not imported IsoMedia import LesTroyensAct2.mp4 - track ID 202 - Audio (SR 48000 - 2 channels) Warning: track ID 201 has references to a track not imported Saving to ../LesTroyensAct2.mp4: 0.500 secs Interleaving azed@azed-N110:~/Desktop$ Thus no problems here either – produced a new out-file at the stipulated location; and the new file played fine. Finally, I tried adding a chapters-file to the mix: azed@azed-N110:~/Desktop$ MP4Box -new -fps 30000/1001 -add LesTroyensAct2.mp4#video -add LesTroyensAct2.mp4#audio -chap LesTroyensAct2Chaps.txt ../LesTroyensAct2.mp4 IsoMedia import LesTroyensAct2.mp4 - track ID 201 - Video (size 608 x 336) Warning: track ID 201 has references to a track not imported IsoMedia import LesTroyensAct2.mp4 - track ID 202 - Audio (SR 48000 - 2 channels) Warning: track ID 201 has references to a track not imported Segmentation fault (core dumped) And so the re-mux aborted at the add-chapters point. I am wondering: does this behaviour, in both precise and raring, have anything to do with the update of libavcodec-extra-53 which both systems recently received. As I understand it, libavcodec-extra-53 handles x264-encoding and is a dependency of gpac. Final point: since chapter-imorting cannot be "turned off" in OGMRip, this bug (if such it be) effectively kills OGMRip as a DVD ripper. ** Affects: gpac (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1176596 Title: MP4Box crashes in Precise and Raring when importing chapters text-file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gpac/+bug/1176596/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
