Ok, to preface, I am trying to test dvdrip's functionality with
Transcode v1.0 and greater on Gentoo, so if any of these bugs are
transcode related, please by all means, let me know, but I'm trying to
isolate the ones that I think may be related to transcode. Gentoo is
moving to Transcode 1.0, and I'm trying to help ensure dvd::rip survives
the transition.
Now, there are a few general bugs I have run across in my testing, they
are as follows:
1) lsdvd incorrectly reads NTSC content for which transcode can recover
the full progressive content directly. (FILM is the term used in Windoze
ripping utilities...) These entries in the TOC are designated to have
29.979 fps, however, when transcode goes to rip them, dvd::rip throws up
an error message because transcode correctly detects that the frame rate
will in fact be 23.976. I am working to duplicate this on another DVD,
but I do not believe it to be specific to this DVD, as when I remove
lsdvd from my system, and re-read the TOC, the correct frame rates of
23.976 are reported.
2) in the "RIP Title" dialog, the "View selected title/chapter(s)"
button attempts to launch mplayer. It however specifies the selected
angle value, which dvd::rip (and i assume transcode) count from 1,
whereas mplayer counts from 0, so it tries to select angle 1, an oft
non-existent angle according to mplayer.
3) in the "Transcode" dialog, if you set in your preferences a default
container of "ogg", the "AC3" tab for Audio encoding doesn't appear
until you manually re-select the "ogg" container format. Then it shows
up as normal.
These are a few of the bugs I ran into that could well be
Transcode-1acting up:
1) When transcoding frame ranges, w/o PSU, one or both of the passes
will often fail right at the end. CPU at 0%, encoding usually near 100%,
sometimes over, but no activity. Cancelling successfully removes all the
tc* programs, but encoding never finished.
2) One particular DVD rips with _very_ odd errors, including black
screen/silence for first 3 minutes, and audio disappearing at a
seemingly random point shortly past 6 minutes. I suspect this may be the
particular DVD however, and will test further with other discs.
Please let me know if these bugs are worth further attention, I would be
glad to supply further/more information, or even work on a patch if
someone can point me in the right direction for fixing. =]
