Re: [Openvip-users] real-time playback

[<ton...@po...>]

Hi,

I'm not quite sure if I understood your question correctly. Are
you asking about real-time video rendering? This is unfortunately
too slow to be possible.

But you can observe the effects of different module parameters
using the GUI: There is a preview included in every
filter/transition settings dialog and you  can also open the
preview window using the View menu. Regards

No, but the warnings are there for a reason.  It means this isn't
supported, and might break in the future.

I didn't check recently but in the past things like this could prevent
the automatic rebuild rules from working.

[Openvip-users] real-time playback

[Anthony G. <gr...@sp...>]

Hello -

	Are there any examples of real-time audio and/or video playback using
openvip.  I have an idea of how it might be done, but a worked example
would be a better start.

	To be clear, by "real-time" I mean in a way that allows for real-time
tweaking of module parameters during playback - not simply by playing
buffered output popping out the end of a fixed network.

Thanks,

AG

[Openvip-users] UPF Makefile buglet

[Tom T. <tr...@re...>]

From upf/Makefile.am:

SUBDIRS = tools/omniidl include src tools tests examples

This is technically wrong, and newer versions of automake will
complain about it.

One fix would be to rearrange directories so that omniidl is its own
top-level directory.  Another possible fix would be to arrange it so
that all of "tools" can be built first.

For my utter surprise the setting dialog file for my plugin is not being =
recognised by openVIP. I have used the following code to check/debug in =
the settingsDialog. py file
/code
def LoadContent(self, plugin):
        """Loads settings dialog for plugin 'plugin'."""
        classname=3DNone
        try:
            try:

                wxMessageBox(classname)
                exec 'import settings_dlgs.%s%s' % (plugin, =
self.GetClass())
                classname=3Dplugin+self.GetClass()
                wxMessageBox(classname)
            except ImportError:
                wxMessageBox(plugin)
                exec 'import settings_dlgs.%s' % plugin

                wxMessageBox(classname)
        except ImportError:
            wxLogError("Import Error: No settings available for '%s'." % =

I get the name of the file exactly as existing. But I get always import =
Error. The supplied crossfade etc also give same expected nmessages but =
it goes thru without any error. Is there any other list to which I need =
to add my plugin class (same as python file)? This is perplexing.

I replied on 7th Aug, but did not get any further response. So repeating.
1. By the use of LogError function I could check on the input frame numbers.
They start at #1 (not #0 as to be expected)and end at 1 less than the
m+length. But immediately on this last frame I get message that unable to
read frame #720 and shuts down with error. This happens with all
transitions( including crossfade and sweep).  Also the transition starts
only after a little right of the Left boundary of transition in the GUI. The
last frame also ends a little right of the right boundary. Is there a
mismatch between GUI and Processing?
2. Removing in_vfawvi.dll made it not recognising avi file. So it did not
force to ffmpeg to read it.
Do you want any further testing?

        I do not know how to do it. I checked for n==0 and n==m_length. It
didnt work. I inserted a printf statement  to print every frame number
requested in my transition right at the begining of process, but could not
see any output on screen, eventhough the transition is working. Pl advise
where I can put a "message display" if such a thing exists. There must be
someway of communicating in case of errors in parameters input. I find that
the param check done at set params  stage do not have access to frame and
clip info so that some params which have limits depending on frame width,
height or length of clip, I am unable to report such errors. Presently I am
checking them and if outside then forcing them to be within acceptable
limits.

     in_vfwavi.dll , when deleted I could not read the input file. It did
not recognise input file as a media file.

    I have only one avi file. I using the GUI, Insert  file in Edit panel,
first time place at the begining of time line on top video file, then again
insert file (the same file but at a later time on the lower video slot).
Then insert transition in the overlap area. View  by preview panel. I will
try having a copy of video file.

Re: [Openvip-users] Help

[<ton...@po...>]

It looks like there is a bug in
src/core/video_transition_proxy.cpp module. To be sure, could you
check the numbers of frames that the core asks your plugin for?
Are they 0-719 or some other, too?

I'm also surprised with the message 
"unable to read frame 720. Giving an empty frame". I think it
didn't come from OpenVIP but rather from Video for Windows
library. What happens if you use just ffmpeg (try to delete
in_vfwavi.dll)? 

What does the sentence "I use same file as
 inputs but offsetted" mean? Do you try to make transition
between two clips corresponding to the same video file? If yes,
does it help to make a copy of the input file so that the two
clips correspond to two different files?

[Openvip-users] mildly confusing doc. comment

[Tom T. <tr...@re...>]

I found the documentation comment for
create_thumbnails_generator a bit confusing.  Right now it says:

        Note that the output is image representation in both cases, with
        dimensions \a width x \a height, with \a frames in total.

How about changing this to something like:

   Note that the output is an image in both cases, consisting of
   \a frames total, arranged left-to-right.  Each frame has dimensions
   \a width x \a height.

I wasn't originally sure whether `width' referred to the width of an
individual frame, or the overall width.

[Openvip-users] "install" problem

[Tom T. <tr...@re...>]

I wrote a simple little program using the highlevel API, and I found
that it didn't run properly unless I ran it with pwd == openvip/bin.

I think this code form networkload.cpp is to blame:

    #define OPENVIP_DTD_CATALOG   "data/dtd/openvip-catalog.xml"
  [ ... ]
    xmlLoadCatalog(OPENVIP_DTD_CATALOG);

I suggest that openvip_create() change to take a base directory as an
argument, and then openvip look in <base>/plugins for its plugins and
<base>/data for the DTDs.  What do you think?

Also, ideally openvip would have some kind of "make install"
step... is use of bjam a permanent thing?  I notice upf uses auto*.
Anyway, if `make install' worked, we could put all this stuff in
$libdir/openvip/.

Re: [Openvip-users] Help

[V.C.Mohan <mo...@ho...>]

I have tried the preview with my transitions as well as crossfade and sweep.
with all transitions I get the message "unable to read frame 720. Giving an
empty frame'. however with some of my transitions the processing continues.
With others the application closes. The debug info  for crossfade
'unhandled exception access violation. pythonw.exe(python22.dll) . Incase of
sweep once I got error and closing message but a second attempt only
produced unable to read frame 720, returning a empty frame. For some of my
dlls I get div by zero as the unhandled exception. context shows
(mytransition.dll, but code displayed is in assembler ). By inserting a line
of code in my transition at the start "if(n>=m_length) return b; I could not
get rid of the error. At frame 720 there should be no call to the transition
dll. My input consists of 720 frames avi type 2 file. I use same file as
inputs but offsetted.
I have tried rendering also. The result is same error.

I am using python23 and have wxpythonwin32-2.5.1.5-PY23-exe
vdub does not show any error in my input.  Also if I just process with
openvip this input by any filter and preview I do not get any error.

Hi,

I have tried both crossfade and sweep on a few files but I didn't
manage to get any errors. Does the error occur with every input
file or just with a single one?

In case you are not able to upload your files anywhere could you
find out (using the debugger) the module (i.e. the source file)
which caused that error?

Antonin Slavik

I have tried using crossfade as well as sweep which are transitions included
with pack and have the same result. It appears that I get this error in the
preview stage when I click on the 720th frame i.e. just after transition.
The error at last frame occurs after rendering with any transition. Since
the original source avi file will be very large,  sending will be a problem.
Which exactly you want me to send? Shall I save timeline and send it?

You should probably install some codec package such as K-Lite
Codec Pack, Codec Pack All in 1 etc. I've tried these two
packages together with WM Player 9 which was able to play
OpenVIP-rendered files (both avi and mpeg with default codecs)
without any problems.

I'm afraid it is not possible to solve this problem unless you
send us the code of your transition together with a timeline or
network which causes the error.

Re: [Openvip-users] Compilation Problems

[<ton...@po...>]

Hello,

all compiled plugins reside in the "bin" directory (it is a
subdirectory of the toplevel directory).

If you run bjam from command line it always reports the number of
succesfully updated targets and the number of targets which
failed to compile.

It is also possible to list all available plugins by running the
script "list_plugins.py".

Regards,

Antonin Slavik

[Openvip-users] Compilation Problems

[V.C.Mohan <mo...@ho...>]

Sir,
    Further to my last message, atlast I am able to compile my plugins =
sources in VC++ as well as with bjam. I am able to compile both in dbug =
and release modes of VC++. In case of bjam I see a lot of screen =
activity and finally closing off. But I did not see any dll in the =
openVIP plugins directory. If it compiled then where is the dll located? =
If it did not compile then why all that screen activity for a long time? =
If theres an error how do I get to know of it? I am not sure that I will =
be able to catch it with break button as it goes very fast.

Mohan

As I have very little experience with VC++ I can't identify the
problem. When compiling using bjam you should use

bjam -sTOOLS=msvc

for debug mode compilation and

bjam -sTOOLS=msvc -sBUILD=final

for release mode.

The numbering in case of a clip with 720 frames is really from 0
to 719. You should not ask for any frames outside this range.

Yes, it is case sensitive.

[Openvip-users] compilation problems

[V.C.Mohan <mo...@ho...>]

Thanks for the reply I could see in the lists page. I have edited the =
jamfile included in the distribution for windows and inserted those two =
lines by typing afresh and not copied your entries. That file should be =
correct as it is doing something when these two lines are =
omitted/commented out. However as I mentioned in my another mail sent a =
little while back, I could compile in my regular VC++ compiler in debug =
mode by inserting a line #define DLL_BUILDING MODULE at the beginning of =
code. Curiously same code could not be compiled in release mode. =
Probably some definitions in either compiler configurations or jamrules =
or some other file need to be setup as otherwise each plugin will be a =
fat 450kb+ size.

I have another problem. While previewing the working of the transition =
with a clip of 720 frames long, I get a message stating could not open =
frame 720, inserting a frame. This insertion is a blank frame with a lot =
of noise. In such cases can it not insert the previous frame? Also why =
this error at all? If the numbering of frames is from 0 the last will be =
719 and not 720. Since I always ask for the same frame number as =
received in the call there should be no such error!

In the setparams part of coding in case of strings is the input case =
sensitive? If a parameter say "direction" is specified as "north" or =
"North" or "NORTH" will be treated differently?=20
