[DVDnav-discuss] Debugging non-playable movie

[Hans Petter Selasky]

Hi,

A friend of mine which does not know so much about computers bought a movie and wanted to play it under Linux. Unfortunately the movie doesn't play, due to some strange formatting, which I think is done by purpose by the movie maker

First error observed:

./libdvdread-4.2.1/src/ifo_read.c

The ifo_filename needs to be extended one byte, hence the filenames are one byte too long and snprintf's need to be updated too.

char ifo_filename[14];

Second error observed:

  if(vts_ptt_srpt->nr_of_srpts > info_length / sizeof(*data)) {
    fprintf(stderr, "libdvdread: PTT search table too small %d %d.\n",
        (int)vts_ptt_srpt->nr_of_srpts, (int)(info_length / sizeof(*data)));
    goto fail;
  }

vts_ptt_srpt->nr_of_srpts = 99

info_length / sizeof(*data) = 2

After making these changes only the copy warning is playable.

I can test patches in libdvdread. Please keep me CC'ed hence I'm not subscribed to this list.

How to proceed next?
