New Filter: DVInfo

[WarpEnterprises]

This FILTER grabs the timestamp and recording date info out of a DV-AVI.
It should work with Type-1 and Type-2, standard AVI and openDML.

You can specify the time/date as an expression which is then Subtitle'ed on the video clip.

Simplest example:

LoadPlugin("c:\myprojects\dvinfo\release\dvinfo.dll")

file="c:\myprojects\type2.avi"  # so you don't need to type the filename twice

Avisource(file) #open the video content
DVInfo(file, "rec_time") # reads the recording timestamp

The filter does NOT read the video content, it only reads the timestamps of the framenumber currently passed through!

You may also look here for something closely related...


Technical note:
it uses AVI-file code from "kino", which I had to modify a little.

[WarpEnterprises]

Small Update:
* added parameter "show_error" to switch off error messages
* updated AVI code to latest version of kino
* added default value for "output" so it's enough to write DVInfo(filename)
* made docs nicer

WarpEnterprises,

Thanks for the filter. It is really cut down a lot of step to have recording time and date inserted into the clip. Before this I used DVSubmaker, subresync, textsub for this job. BTW, is there anyway to have AM/PM instead of 24-hours time format? Perhaps, it is good to have this feature inserted as well as different language option.

Thanks.

[WarpEnterprises]

it's there, well hidden, read the readme

It uses the current (windows) localisation!

Example for result like: "26.Juli 2003 04:01 PM"

dvinfo(file,"rec_time",rec_format="%d.%B %Y %I:%M %p")

Here are all format specifiers:

Codes for output formatting 
%a Abbreviated weekday name 
%A Full weekday name 
%b Abbreviated month name 
%B Full month name 
%c Date and time representation appropriate for locale 
%d Day of month as decimal number (01 – 31) 
%H Hour in 24-hour format (00 – 23) 
%I Hour in 12-hour format (01 – 12) 
%j Day of year as decimal number (001 – 366) 
%m Month as decimal number (01 – 12) 
%M Minute as decimal number (00 – 59) 
%p Current locale‚s A.M./P.M. indicator for 12-hour clock 
%S Second as decimal number (00 – 59) 
%U Week of year as decimal number, with Sunday as first day of week (00 – 53) 
%w Weekday as decimal number (0 – 6; Sunday is 0) 
%W Week of year as decimal number, with Monday as first day of week (00 – 53) 
%x Date representation for current locale 
%X Time representation for current locale 
%y Year without century, as decimal number (00 – 99) 
%YYear with century, as decimal number 
%z, %Z Time-zone name or abbreviation; no characters if time zone is unknown 
%% Percent sign  
The # flag may prefix any formatting code. In that case, the meaning of the format code is changed as follows. 

%#a, %#A, %#b, %#B, %#p, %#X, %#z, %#Z, %#% # flag is ignored.  
%#c Long date and time representation, appropriate for current locale. For example: “Tuesday, March 14, 1995, 12:41:29„.  
%#x Long date representation, appropriate to current locale. For example: “Tuesday, March 14, 1995„.  
%#d, %#H, %#I, %#j, %#m, %#M, %#S, %#U, %#w, %#W, %#y, %#Y Remove leading zeros (if any).

Great...

Thanks.

As an alternative the same kind of plugin which I have done for myself long time ago but didn't announce widely: http://mvideo.nm.ru
Unlike DVInfo, my plugin has function for automatic time stamping when date/time changes by some value more than given threshold.

[WarpEnterprises]

New version (2003-12-16): I added the autoframe-features to DVInfo, too.

http://www.avisynth.org/warpenterprises/

[Basilik]

New features added to my plugin DVTimeStampEx (note, name changed a bit):
1) you can define a timeoffset from original taping time
2) you can force the timestamp to appear in auto mode if no DV time change occured for a long period
3) multiline support
4) font is fully customisable
5) visual effects added (same as in my SubtitleEx plugin)

See all details on my site.

does DVinfo support DV files larger than 4GB? I have problems with it when processing a 6GB DV AVI, but it works OK on files smaller than 4GB...

[WarpEnterprises]

1) how did the error / problems look like? (error messages or the like)
2) What AVI Type (1 or 2) did you use?
3) Was there any sound inside?

[whwhwhwh9]

#LoadPlugin("decomb521.dll")
LoadPlugin("TDeint.dll")
LoadPlugin("DVinfo.dll")
#LoadPlugin("MPEG2Dec3dg.dll")

filename = "g:\uvs050806-003.AVI"

v = DirectShowSource(filename)

### for mpeg2: DirectShowSource("test.mpg")
### for DV AVI: DirectShowSource("test.avi")

AssumeFieldBased(v)
AssumeBFF(v)

v2 = TDeint(v)
v3 = BilinearResize(v2, 352, 288)

DVinfo(v3, filename) # <---- Line 19

[WarpEnterprises]

two more questions:
- does the error occur when you open the AVS or after you do some seeking beyond a frame?
- does it crash without AssumeFieldBased(v) ...BilinearResize(v2, 352, 288) ?

[whwhwhwh9]

To your question #1: I didn't even have chance to seek. I just opened the AVS file in VirtualDub, then it took 100% CPU cycles, then about 2~3 minutes later, error message pops up.

To your question #2:

LoadPlugin("decomb521.dll")
LoadPlugin("dvinfo.dll")
LoadPlugin("TDeint.dll")
filename = "\tt.AVI"
v = DirectShowSource(filename)

#AssumeFieldBased(v)
#AssumeBFF(v)

#v2 = TDeint(v)
#v2 = FieldDeinterlace(v)
#v3 = BilinearResize(v2, 352, 288)

dvinfo(v, filename) # <==== line 14

[WarpEnterprises]

get the new version (2005-08-11)
http://www.avisynth.org/warpenterpri...ex.html#dvinfo

Thanks for reporting, it was indeed a bug for files > 4GB.

[whwhwhwh9]

got the new version, and it works great.

WarpEnterprises: Could you (or possibly someone else) make it possible to display the timecode whenever the day of month changes?

[WarpEnterprises]

Isn't that the same if you use a large "threshold" value (e.g. 10000 seconds) or do you really want to display the timecode exactly at midnight with your video actually spanning over midnight?

[Boulder]

I sometimes have stuff that is shot before midnight and then continued during the early hours of day. It would be much easier to have a single option for displaying when the day of month changes than calculating the threshold for each instance

[WarpEnterprises]

After some thought it turned out to be trivial AND general, check it:

Is it still GPL (since source is not included)?
