I wanted to test transcode (specifically, tccat). Usually I use lsdvd (not in the book) to see how the DVD is organized, but on this particular DVD that just gives some error messages from libdvdread about failing to read blocks, then segfaults.
So, I tried running tccat "blind" : tccat -i /dev/dvd -T 1,-1 >filename.vob That reported some failures in libdvdcss, then scrolled up and eventually seemed to end in error: [dvd_reader.c] critical: Read failed for block 1854485 libdvdread: Can't seek to block 1946410 [dvd_reader.c] critical: Read failed for block 1915639 libdvdread: Can't seek to block 2017234 [dvd_reader.c] critical: Read failed for block 1986463 But interestingly enough I have 187M for the start of the program (a bit under 2 minutes). Perhaps it is just this DVD. Nope, tried another one - libdvdread: Found 7 VTS's libdvdread: Elapsed time 1 libdvdread: Can't seek to block 191821 [dvd_reader.c] critical: Read failed for block 0 libdvdread: Can't seek to block 208444 [dvd_reader.c] critical: Read failed for block 16623 libdvdread: Can't seek to block 384185 [dvd_reader.c] critical: Read failed for block 192364 libdvdread: Can't seek to block 614799 [dvd_reader.c] critical: Read failed for block 422978 etc and this time the output file was empty (this one is a DVD where I got the vob file on another box back in May). Looks as if my last attempts to use tccat and lsdvd were in May. There were also reports like libdvdread: Error cracking CSS key for /VIDEO_TS/VTS_01_1.VOB (0x0002ed4d)!! on both DVDs, but the first one eventually managed to produce that couple of minutes of video, so libdvdcss seems ok. For the moment, I think libdvdread is broken in 7.9. ĸen -- This email was written using 100% recycled letters. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
