This actually looks to me as an issue in libavcodec. However, your commandline is pretty convoluted.
Any chance to reproduce this with avconv? Also, was this commandline generated by a frontend? If yes, which one was that? ** Summary changed: - Mencoder error 64 bit U12.04 + Mencoder error: Error, Invalid timestamp=1, last=1, encoding to mpeg4 ** Changed in: mplayer (Ubuntu) Status: Confirmed => Incomplete ** Changed in: medibuntu Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1000973 Title: Mencoder error: Error, Invalid timestamp=1, last=1, encoding to mpeg4 To manage notifications about this bug go to: https://bugs.launchpad.net/medibuntu/+bug/1000973/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
