empty DATE in tagsFound of Bus.Tag #37

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. setup playbin and connect Bus.Tag listener to bus
2. set input file (mp3 or ogg)
3. output tagsFound in listener

What is the expected output? What do you see instead?
The files contain a Date (tested with mp3 and ogg) but I see only that a
tagName "date" is found but tagData is an empty String. Other tags (title,
artist, album, track-count, track-number etc. work fine)

What version of the product are you using? On what operating system?
OS:
Linux 2.6.31.12-174.2.22.fc12.x86_64 #1 SMP Fri Feb 19 18:55:03 UTC 2010
x86_64 x86_64 x86_64 GNU/Linux

gstreamer-0.10.25.1-3.fc12.x86_64
gstreamer-java-1.3-2.fc12.x86_64
jna-3.2.4-3.fc12.x86_64

Please provide any additional information below.
I tried it with java 1.6 and java 1.7

java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) 64-Bit Server VM (build 16.0-b13, mixed mode)

java version "1.7.0-ea"

as usual:-) is it with native gstreamer?

Native gstreamer is OK. Even the TagList argument of tagsFound(...) shows the 
date
when printed with System.out.println(arg1):

taglist, 
album=(string)"You\ Rock\ My\ World", 
comment=(string)Single, 
title=(string)"You\ Rock\ My\ World\ \(A\ Cappella\)", 
artist=(string)"Michael\ Jackson", 
date=(GstDate)2001-01-01, 
genre=(string)Pop, 
track-count=(guint)5, 
track-number=(guint)5, 
encoder=(string)"Xiph.Org\ libVorbis\ I\ 20040629", 
encoder-version=(guint)0, 
audio-codec=(string)Vorbis, 
nominal-bitrate=(guint)160000, 
bitrate=(guint)160000;

But I think the GstDate-Type seems to be not implemented.

There is a type defined in gstreamer-java called GDate that I suspect is what 
should
be used here. However its implementation seems incomplete (the class only has a
constructor and a dispose method).
The only reference to this type is in GstStructureAPI.java, and it is just a
commented out method:
boolean gst_structure_get_date(Structure structure, String fieldname, GDate 
**value);
Not sure how to finish this functionality.

can you attach a small example code?

#r347 add support for GDate try with the latest svn or send example code.

Attached test class. Compile it and run it with

java at.td.gst.Test AUDIO_FILE

It first prints the raw arg1 from tagsFound(...) which shows the 
"date=(GstDate)"
entry with a value, and then the list which I get from a loop over 
arg1.getTagNames()
and arg1.getValues(tagName).

With the current version the tag "date" in the loop is present but empty.

Please ignore my Java-code-style. I copied it from my current project and 
merged it
into a one-file-test to keep the testing simple.

OK, I attached a file and the output I see is the following (interesting: the
"date=(GstDate)2001-01-01" in the raw arg1-output and the line with "date: " 
but no
value in the output-loop over tag names and values):

processing:
taglist, container-format=(string)Ogg;
container-format: Ogg
processing:
taglist, album=(string)"You\ Rock\ My\ World", comment=(string)Single,
title=(string)"You\ Rock\ My\ World\ \(A\ Cappella\)", artist=(string)"Michael\
Jackson", date=(GstDate)2001-01-01, genre=(string)Pop, track-count=(guint)5,
track-number=(guint)5, encoder=(string)"Xiph.Org\ libVorbis\ I\ 20040629",
encoder-version=(guint)0, audio-codec=(string)Vorbis, 
nominal-bitrate=(guint)160000,
bitrate=(guint)160000;
album: You Rock My World
comment: Single
title: You Rock My World (A Cappella)
artist: Michael Jackson
date: 
genre: Pop
track-count: 5
track-number: 5
encoder: Xiph.Org libVorbis I 20040629
encoder-version: 0
audio-codec: Vorbis
nominal-bitrate: 160000
bitrate: 160000
