Hi Guys -
Well after a very long session at the keyboard (fortunately for domestic
harmony, my wife is away on a business trip) I am pleased to report that
I can now once more capture MPG straight from IVTV into dvdauthor
without the need to remux.
Thanks to everyone for their help. I will post the details in a new
thread so that other users may have a better chance of finding them but
in summary:
1) I used v4l2 stream_type 3 with 2 B-frames and closed GOPs but
no additional NAV packets. Using insert_navigation_packets=1
causes dvdauthor to report 'SCR moves backwards' then segfault.
2) I had to revert to my old version of dvdauthor (0.6.11) and
apply the patches I previously developed to make it handle IVTV
streams. Thank heavens I'd taken a backup for once.
I'll post the dvdauthor patch and a HowTo on the IVTV website later
today; and I'll see if I can update the patch to make it work on the
current version of dvdauthor (0.6.14).
In the meantime here is my working config:
