subtitles from SRT file

[Shay Tessler]

hello all , i have seen an example for showing text over using the
"textoverlay"

but i was look for a way to play subtitles from a SRT file
i know gstreamer can do this via "GstSubParse"
is there an example of using subtitle file in gstreamer-java

thank you

Why not create a "subparse" element and use it?

[Roberto Faga]

I'm using subtitles with subparse module:

videoComponent = new VideoComponent();

Element videosink = videoComponent.getElement();
Element textoverlay = ElementFactory.make("textoverlay", "textoverlay");
subtitle = ElementFactory.make("filesrc", "filesrc");
Element subparse = ElementFactory.make("subparse", "subparse");

// Set subtitle file location
subtitle.set("location", "/home/faga/Temp/subtitle.srt");

Bin bin = new Bin("myBin");

bin.add(subtitle);
bin.add(subparse);

bin.add(textoverlay);
Pad pad = textoverlay.getPad("video_sink");
GhostPad ghostpad = new GhostPad("sink", pad);
bin.addPad(ghostpad);
bin.add(videosink);


// Set params of textoverlay (position, font, shaded, etc)
textoverlay.set("valign", "top");
textoverlay.set("halign", "right");
textoverlay.set("shaded-background", "yes");
textoverlay.set("font-desc", "Sans Bold 16");

Element.linkMany(subtitle, subparse, textoverlay, videosink);



Then you have the bin to play, pause or do what you want. You still
need to point to a video file, and I pasted this code into original
VideoPlayer class (from org.gstreamer.swing.*)

thank you all for quick comment ,
this example is not working , i see black window
this happened when adding ,the subtitle and subparse and then linking
them all

here is my code here

thank you again

Hi again,

I pasted my class which is working perfectly:

http://pastebin.com/K89vWS4s

However, I see that you're using Gstreamer on Windows, you can try
first running on CMD "gst-inspect subparse" to see if this element is
available. Last version of OSSBuild which I tried (I think on January)
there isn't this module, so subtitles was not possible to work on
Windows.

also seems that i had to put this line of code before creating the
player :

Gst.init("Swing Player", new String[]{strMovie});

other wish i get this error :

Hi Shay,

You can create first a Java File to subtitle, check if it exist and
pass as parameter "getAbsoluteFile()". You're using URI where it
should be the absolute file path:

String strSubtitle = "file:///Y:/Movies/500 Days Of Summer (720p)/
500.Days.Of.Summer.720p.BluRay.x264-METiS.srt";

to

String strSubtitle = "Y:\\Movies\\500 Days Of Summer (720p)\\
500.Days.Of.Summer.720p.BluRay.x264-METiS.srt";

(yes, it's different from playbin, which uses URI)

Try this one, I don't have a windows machine to check if this now
works. If still not, try creating a Java File (from java.io), check if
it exist and then pass as parameter: "subtitle.set("location",
srtFile.getAbsoluteFile());"

[Shay Tessler]

ok this is what i do
mediaPlayer = player;

videoComponent = new VideoComponent();
Element videosink = videoComponent.getElement();
Element textoverlay = ElementFactory.make("textoverlay",
"textoverlay");
subtitle = ElementFactory.make("filesrc", "filesrc");
Element subparse = ElementFactory.make("subparse", "subparse");

File file = new File("Y:\\Movies\\500 Days Of Summer (720p)\
\500.Days.Of.Summer.720p.BluRay.x264-METiS.srt");
///THIS PRINTS 'TRUE'
System.out.println("SRTVideoPlayer.SRTVideoPlayer() file:"+
file.exists());
subtitle.set("location", file.getAbsoluteFile());


//TRY THIS FOR OTHER RUN ,ALSO NOT WORKING
//subtitle.set("location", file.getAbsolutePath());

Bin bin = new Bin("myBin");
bin.add(subtitle);
bin.add(subparse);
bin.add(textoverlay);
Pad pad = textoverlay.getPad("video_sink");
GhostPad ghostpad = new GhostPad("sink", pad);

.....

VideoComponenet still not playing the movie , and i see a black
rectangle instead
the problem is that the movie not plays at all

all so this is my main ,just to verify i did ok

public static void main(String[] args){
String strMovie = "file:///Y:/Movies/500 Days Of Summer (720p)/
500.Days.Of.Summer.720p.BluRay.x264-METiS.mkv";

strMovie = strMovie.trim();
strMovie = strMovie.replace(" ", "%20");

Gst.init("Swing Player", new String[]{strMovie});

SRTVideoPlayer p = new SRTVideoPlayer(strMovie);

JFrame f = new JFrame();
f.setSize(800 ,600);
f.setLayout(new BorderLayout());

f.add(p ,BorderLayout.CENTER);
f.setVisible(true);

}

[Roberto Faga]

Yes, it means there is something wrong on the code. By the way, if you don't want to change the sub position from bottom-centered, you can use the suburi and "subtitle-font-desc" on a playbin. Try this code, I tested successfully there:

http://pastebin.com/wkVyhqbr

I think it's easier, since you don't need to build a bin and can use or not a subtitle file. And as a suggestion to gst-java MediaPlayer class, it can has a setSubtitle() and setSubtitleFontDesc() to optionally pass a subtitle location and desc.

[Roberto Faga]

Ah, and here there is a list of all playbin2 properties:

thank you . i also set
playbin.set("subtitle-encoding", "Windows-1255");
to put hebrew subtitles :)

What happend when i want to replace subtitle while playing
or change subtitle offset
can i do that ?

thank you .

I'm not sure, but I think you need to stop (not pause) and play the pipeline again if you change the sub file. And I think it's easier to change the SRT offset, even if you write on a temp file, as I think it'll be hard to change the offset on subparse element (I didn't found doc about its properties)

or it will be more easy to read and parse the subtitle files my self
and display them using the "textoverlay" ?

Try getting a video only pipeline working. Use basic examples as your starting point. Make sure your pipeline actually runs with gst-launch - then you can use exactly the same pipeline using Pipeline.launch().

i was at gstreamer irc channel
they told me that change subtitle delay at playbin2 is not yet
available
and its possible but complicated
i will try to parse subtitles using java , and play with textoverlay
and i will post here when i am done
maybe someone will be interested in my code
