Revision history for Perl extension Video::DVDRip
0.35 Wed Mar 13 2002, joern
Features:
- Cluster mode:
- added test procedure which checks if a node is
configured correctly: ssh connection, r/w NFS access
and transcode version match are checked. Currently
this works by comparing the output of a test script
executed on the node and the machine where the dvd::rip
GUI runs on. You can execute the test procedure
from the "Edit Node" window.
- the "audio processing" job is now splitted into two
jobs: audio transcoding and a/v multiplexing. This
enables running the audio transcoding in parallel with
other jobs, e.g. video transcoding. Finally the audio
and video chunks have to be multiplexed, what is
single threaded again, but much faster than the old
audio processing job, which blocks the project nearly
at the end for a longer time, what was really
frustrating ;). Thanks to Rainer Lay for his idea.
- minimum chunk count is now (online nodes + 1) instead
of 2.
- you can start dvdrip with option -c to open the
cluster control window without opening a main window
Bugfixes:
- audio bitrate was always set to AC3 passthrough bitrate
when a project was opened from file
- Cluster mode:
- in rare cases and when there was heavy traffic on the
network, the Cluster Control Daemon erroneously
determined that a node is offline and aborted the
current job. Now the offline state is checked twice,
so this shouldn't happen anymore.
0.34 Sun Mar 03 2002, joern
Note:
- Cluster mode: you need the pstree command on the cluster
control computer from now
Features:
- Cluster mode:
- now you can reset a single job, if something went wrong
with it, so you don't have to start the whole project
again. All dependent jobs are reset automatically.
Thanks to Sloan Poe for his suggestion.
- cluster mode scheduler optimization regarding the
delegation of IO intensive jobs preferably to nodes
with local resp. fast file system access. In earlier
versions a local node could be blocked too early by
a non-local job, so local jobs later had to be
delegated to non-local nodes. The scheduler now
tries delegating local jobs to local nodes first,
and then normal jobs to idle nodes, if there are any.
- you can optionally let dvd::rip delete the VOBs
after finishing, making bigger project queues possible,
even with little harddisk space (but is risky, if
something goes wrong).
- AC3 audio passthrough support. If you're upgrading and
you have an existent project, you need to rip the title
again, because the necessary probing is done directly
after ripping. There is no restriction for new projects.
- Currently it's not possible to use AC3 passthrough in
cluster mode, because I hadn't the time to test it.
- the layout of the Transcode Tab changed slightly, to get
space for the AC3 radio buttons.
- all directories are now created with mode 0775, to
prevent file access problems in cluster mode, if
the user ids of all nodes doesn't match. Suggested
by Sloan Poe.
- range transcoding: default for the start value is 0.
default for end value is number of frames. Until now
you had to fill both values to get a range transcoding.
Suggested by Douglas Bollinger <dcb AT 321.net>.
Bugfixes:
- Cluster mode:
- on some systems stopping a node didn't work (dvd::rip
hung). Now the child process is killed explicitely and
this should work on any system. You need 'pstree' on
the cluster control computer from now. Thanks to
Sloan Poe, who helped me debugging this problem.
- in multipass mode dvd::rip tried moving the AVI file
to its final destination after the first pass. This
threw an error message, but had no other effect.
Anyway it was useless and confusing.
- switching off avisplit of a just added project didn't work
- removed DVD mount point from preferences, because this
isn't needed anymore
0.33 Tue Feb 19 2002, joern
Bugfixes:
- The node name/hostname feature didn't work. The cluster
control daemon always tried to fping the node name instead
of the hostname. Thanks to Rainer Lay for the bug report.
0.32 Mon Feb 18 2002, joern
Features:
- (one feature so this isn't only a bugfix release ;)
You can enable a transcoding preview window. You need
the filter_preview transcode plugin, which is build
automatically if you have libdv installed on your system.
Also your X Server must have XV support.
Really nice feature. Useless, but fancy ;)
Warning: closing the preview window will kill the
transcode process.
Bugfixes:
- Some cluster jobs were aborted due to timeout accidentally.
Because there occur some really strange problems with
the output of avimerge, I disabled the timeout completely.
This shouldn't matter, because it was added to prevent
hanging ssh sessions which prompt for a password. This
case is catched anyway not using a timeout, so everything
should work better this way. Thanks for the reports to
Andrew Yantis and Rainer Lay.
- project progress didn't count aborted jobs. They are now
added to the waiting value. Thanks to Rainer again for
this one.
- nice -n made problems with tcsh. Using /usr/bin/nice
instead. Guess who reported this one? Yes. Thanks Rainer ;)
- no progress was shown on avisplit due to a bug in the
avisplit output parsing regex.
0.31 Sun Feb 17 2002, joern
Features:
- You can provide additional transcode options on the
Transcode Tab. These options are added to the
internal transcode call, resp. they override corresponding
options already computed by dvd::rip. This is for experts
who want to use special transcode features not currently
officially supported by dvd::rip (or to fix dvd::rip bugs
which are not fixed yet ;).
- adjusting the nice level of the transcode process per
project (also used in cluster mode) on the Transcode Tab.
Suggested by Hrvoje Husic.
- Cluster Mode:
- error handling for remotely executed commands. The last
lines received from the command are logged, so you can
see what's going wrong. Also the corresponding node will
be aborted. You have to start it again, otherwise no jobs
will be scheduled to it. This prevents infinite job
execution on a false configured node.
- internal node name and hostname of the node are now
distinguished (useful to address multi processor machines
as multiple nodes). Suggested by Rainer Lay.
- additional transcode options per node (samy funcionality as
described for non cluster mode above). One good example
for this is increasing transcode threads if you have a multi-
processor node (e.g. -u 4,2). Suggested by Peter Lohmann.
Bugfixes:
- cluster daemon hung if ssh prompted for a password.
- made TOC list wider so content should fit better
0.31_05 Tue Feb 13 2002, joern
Bugfixes:
- All regarding the cluster mode and reported by
Rainer Lay <Rainer.Lay AT informatik.uni-erlangen.de>
- command execution via the hardwired 'ssh -CP' command
made problems, at least with OpenSSH. You now can
configure the ssh command per Node in the Edit Node
window. Default is 'ssh -C' which should work on most
systems.
- many commands had a construct "test dir || mkdir -p dir",
where the "test" command is a nop, because "mkdir -p"
doesn't fail, if the directory exists. Removed the "test"
command.
0.31_04 Tue Feb 12 2002, joern
Features:
- Added a job list to the cluster mode, accompanied by
rewriting some internals. This was necessary to get rid
of the PSU problem without messing up the internal
cluster workflow. The advantage is, now you can exactly
see what steps have to be done.
Bugfixes:
- cluster mode now supports titles encoded in more than
one program stream unit. Thanks to Thomas Östreich for
his help.
- Net::Ping was loaded in cluster mode, but is not
required anymore.
- Hrvoje Husic told me, that 760 MB seems to be the maximum
to burn on an 800 MB medium, so I corrected the
corresponding disc popup entry.
- Layout of the Transcode Tab was somewhat messed up, at
least with the default Gtk theme. I shrinked the buttons
so now everything should fit. Thanks to Torsten Howard
<torsten AT inetw.net> for reporting this "buglet"
(his word ;)
0.31_03 Sat Feb 09 2002, joern
Note:
- Cluster mode is currently useless for titles with more
than one program stream unit (that means: many DVDs
are affected). I'm working on this issue, resp. am
in contact with Thomas Östreich to check, whether
transcode or dvd::rip should fix this.
- WARNING: first finish all your cluster projects before
upgrading to this version, because cluster file names
changed.
Features:
- Cluster Mode
- multipass encoding now supported
- show ETA for transcoding and audio processing states
- optional avisplit and cleanup after transcoding. you
can edit these project properties in the Cluster Control
window
- cluster control daemon can be shut down from the GUI
- multipass encoding: omit audio on first pass,
thanks to Norbert Preining for his hint.
- better NTSC Support, suggested by Norbert Preining
- set frame rate by default to 23.976, but user can
overwrite it
- set transcode options: -g 720x480 -M 2
- disc popup now has an entry for 800 MB discs,
thanks to Hrvoje Husic <husic AT zyn.de> for his hint.
Bugfixes:
- Cluster Mode
- adding a node with an existent name crashed the
cluster control daemon
- dvd::rip GUI now handles cluster daemon exits cleanly
- View AVI works now for cluster transcoded titles
- adding chapter mode titles to the cluster is
prevented now
- project removal threw an exception, sometimes
- no volume rescaling was done
- daemon crashed if a log client sent something
- Storable module was required, even when no cluster
stuff was activated. Thanks to Timothy Harris
<tim AT pongle.net> and Torsten Howard <torsten
AT inetw.net> for their bug reports.
0.31_02 Mon Feb 04 2002, joern
Bugfixes:
- sometimes dvd::rip stopped transcoding too short.
This release should fix this problem. Thanks to
Doug Shea for his bug report and
<ulmo AT garozzo.franken.de> for the hint, which
led me to the solution (omitting the transcode
-c 0-n parameter).
0.31_01 Sun Feb 03 2002, joern
Features:
- all generated files and directories now have names
with correct alphanumerical order. Thanks to Doug Shea
<doug_shea AT alumni.ucsd.edu> for his patch.
WARNING: First finish all projects before upgrading
to this version, because dvd::rip 0.31_01
will badly fail finding files generated with
previous versions!!!
- this is the first public pre-release with cluster
transcoding support. Please refer to the dvd::rip
homepage for documentation about this.
- omit '-J skip="0-2"' in chapter mode if transcode
version >= 0.6 is detected. Thanks for the hint go
to Norbert Preining and Ron Smits <rons AT ronsmits.com>.
Bugfixes:
- opened project was not closed, if you opened it via
command line option and opened a new project via
menu
0.30 Sat Jan 19 2002, joern
Features:
- Christian Lambert sent me an enhanced version of my
fast resize calculator kspread file.
Bugfixes:
- creating a new project failed with an exception,
thanks to Christian Lambert for his bug report.
- splitpipe did not work correctly if you use transcode
0.5.x, thanks to Marc Wäckerlin <mrw AT atheismus.ch>
for his bug report.
- opening the "Show transcode commands" window without
an opened project threw an exception.
0.30_01 Sat Jan 12 2002, joern
Quick pre-release, because I like this feature so much ;)
Features:
- added fast frame grabbing using the vob navigation
information created by 'tcdemux -W' for transcode
>= 0.6.0pre. Frame grabbing now needs a constant
amount of time (2-3 seconds on my A1000 workstation),
regardless of the frame number, you entered.
transcode 0.5.x is still supported, using the -c
option, which is slow because it decodes all precedent
frames. Thanks to Thomas Östreich, who helped me
demystifying the navigation logfile ;)
0.29 Thu Jan 10 2002, joern
Features:
- transcode version is detected on startup, so different
behaviour for different transcode versions is possible.
- preparing for cluster mode: dvd::rip already creates
the neccessary vob navigation logging data.
Bugfixes:
- ripping progress bar enabled for transcode >= 0.6.0
(you *must* use at least transcode-0.6.0pre2-20020107.
Older 0.6.0 pre-releases will cause dvd::rip to fail
badly or just freezing it). dvd::rip uses the new -W
switch of tcdemux to get the progress in the ripping
stage. This gives even enough information to calculate
fps. Coooool... ;)
- You can use dvd::rip with transcode 0.5.x (x>=3),
but the ripping progress bar will be disabled.
0.29_01 Sun Jan 07 2002, joern
Bugfixes:
- DVD TOC reading completely reorganized. Should work now
more reliable with all DVDs. Due to this there is currently
no progress bar for ripping available.
- DVD TOC missed scrollbars
- transcode progress bar did not work with transcode 0.6pre
0.28 Fri Jan 04 2002, joern
Features:
- I added a contrib directory to the distribution, currently
containing a KSpread file which helps calculating fast resize
values. I'm planning to integrate a native and quite more usable
version of this sheet into dvd::rip, but maybe this helps someone
while this feature is not finished. On the other hand the
presets are working well for most DVDs, so this is currently
a nice to have feature for me.
Bugfixes:
- avisplit progress bar missed percentage and ETA.
- fast resize option did not always complain about illegal
values, thanks to Christian Lambert <clambert AT csd.sgi.com>
for the bug report.
0.28_03 Thu Jan 03 2002, joern
Features:
- Full viewing angle support, requested by Certron DiSoni
<certron_80 AT yahoo.com>. You can select the viewing
channel after reading the TOC. Only the selected angle
will be ripped from the DVD. This way I was able to rip
german Star Wars Episode I, with the german intro.
Bugfixes:
- transcode progress bar missed percentage and ETA.
0.28_02 Thu Jan 03 2002, joern
Again a pre-release due to major changes in the progress module
and chapter mode code. Please test it. Thanks.
Features:
- enhanced chapter mode suggested by Tim Currie <jtcurrie AT
mediaone.net>: dvd::rip now shows a multi selection list
of avaiable chapters per title. Now you can decide which
chapters should be ripped and transcoded. Currently no progress
bar is shown in the chapter selection mode, only the elapsed
time will be printed. Also avisplit is currently not available
in chapter mode. I'm not shure, if transcode reports the correct
number of chapters. Often the higher chapters are empty or
at least *very* short.
- major code cleanup in the progress bar module. Among other things
a Gtk input handler is used instead of a Gtk idle function.
This way the GUI responses much better. Also all calculations
(elapsed time, ETA, fps) are done by dvd::rip now and available
for all tasks.
Bugfixes:
- fixed chapter mode transcoding progress bar / logging problem
- dvd::rip failed if the project path was not absolute. Thanks to
George Farris <george AT gmsys.com> for the report.
0.28_01 Fri Dec 28 2001, joern
This is a pre release for testing the new Chapter Mode feature.
Please use this version only, if you're interested in this feature
or if you want to test it in general. Also non-Chapter-Mode ripping
may be affected or buggy.
Features:
- Chapter Mode, suggested by Norbert Preining.
You have to enable this on the RIP Title Tab before ripping,
because each chapter will be ripped into a separate directory.
Transcoding in chapter mode will lead to one AVI file for
each chapter. The progress bar guesses sometimes wrong, but the
result should be Ok. Splitting in Chapter Mode is not supported
and makes no sense in general.
- removed the tcprobe-random-title-permutation workaround,
because this tcprobe bug is fixed in transcode 0.5.3
Bugfixes:
- dvd::rip didn't work with transcode 0.5.3 due to changes
of tcprobe output. Thanks to Thomas Speck <thomas-speck
AT gmx.de> for his bug report. This release has a workaround
fixing this problem. Another solution is to patch transcode
0.5.3 with a patch published by Thomas Östreich on his
transcode homepage.
0.27 Tue Dec 18 2001, joern
Bugfix:
- this release fixes only a minor bug in the debugging window
and log file output. The snapshot command missed the
frame number, so the -c option was malformed.
0.26 Sun Dec 16 2001, joern
Bugfix:
- tar.gz distribution was incomplete. Updated MANIFEST.
0.25 Sat Dec 15 2001, joern
Features:
- create logfile of all processes, display it in a separate
logging tab
- renamed "Snapshot Directory" to "Temp Directory", because
it's used not only for the snapshot images. DivX4 analyze logs
and the dvd::rip log are also stored here.
Bugfixes:
- "transcode & split" did not work
- spaces in project name not allowed, thanks to
Matthias Rieber <matthias AT lsoe.uni-karlsruhe.de>
for the bug report. dvd::rip did not work correctly
with spaces in the project name. Checking of other
user supplied values is still on my TODO list.
0.24 Thu Dec 13 2001, joern
Just a major release, no changes since pre-release.
0.24_02 Tue Dec 11 2001, joern
Features:
- You can open a debugging window, which shows all transcode
commands executed by dvd::rip by pressing Ctrl+T or selecting the
"Debug/Show Transcode Commands..." menu item. Thanks to
Norbert Preining for his suggestion. This should help finding
bugs in dvd::rip, where wrong transcode options are genereated,
or something similar.
- modified 16:9 anamorph fast resizing Preset: added 2nd Clipping
to get rid of 4 black top and bottom lines
- Added a transcode title number field to the rip tab. This way
you can workaround the transcode/libdvdread bug which results
to wrong assigned titles. Please use this with care and only
if you know, what you do. This fields changes only the title
number passed to all transcode commands. The dvd::rip filenames
will be named with the orignally (maybe wrong) scanned title nr.
Thanks to Bjoern Buerger <b.buerger AT tu-bs.de> for his
suggestion.
Bugfixes:
- Preset "16:9 Anam. Enc., No Letterbox, Fast Resize" did not
switch fast resizing on
- Fast Resizing: 32 pixel boundary must be given only for
axes which are resized. Thanks to Norbert Preining for
his patch.
- dvd::rip now checks, whether VOB files are already ripped,
even if the project file says, they're not (e.g. if you
forget to save after ripping, restart dvd::rip and create
a new project for this DVD). Thanks to Norbert Preining
for the hint.
- dvd::rip now checks if the needed programs (transcode,
ImageMagick etc.) are installed and complains if not.
Thanks to Michal Szymanski <msz AT astrouw.edu.pl> for his
bugreport.
0.23 Sun Dec 09 2001, joern
Bugfixes:
- fast resizing: 32 pixel boundary check ommited checking the
clip1 size
- transcode progress label did always show the "split afterwards"
message, even if started without splitting.
0.22 Sun Dec 09 2001, joern
Features:
- Support of the fast resizing algorithm of transcode
(transcode-0.5.2-20011206 is recommended because of
a bug in the horizontal fast resize code in earlier
versions). Fast resizing presumes 32 pixel boundaries.
If you break with this rule, you'll get an error window
on transcoding. I'm planning a wizard which helps
calculating the correct values, because this can be a
brain squeezing task ;)
- Added two new Presets for anamorph transcoding using the
fast resizing algorithm. They should bypass the time,
until the fast resizing wizard is finished.
- Support of multipass DivX encoding.
- Added a button to the Transcode tab for viewing the
transcoded non-splitted AVI file.
- transcode progress label shows, whether started with or
without splitting
Bugfixes:
- applied Perl 5.005 patch supplied by Norbert
Preining <preining AT logic.at>. Thanks.
- DVD read-toc code always tried a mount, even if the
DVD was already mounted. This could confuse systems
using automounter.
0.21 Sat Dec 01 2001, joern
Features:
- transcode 0.5.1 supports 4GB AVI files, so max.
filesize for the bitrate suggestion is now 4000 MB
(was 2000 MB with transcode 0.5.0)
Bugfixes:
- fixed color problem with snapshot images
0.20 Tue Nov 27 2001, joern
- First public release. Should be usable but is not tested
with thousands of DVDs.
