Joining multiple video files!

[Pascha]

Hi,

is it possible to merge/join multiple video files with gstreamer
framework?

Best regards,
Pascha

Mixing multiple videos could probably be done with the 'videomixer' element. The fastest way to construct and try your pipelines is probably using the 'gst-launch' utility - do this before you write any Java code. Once you found a pipeline that works for you, copy it verbatim and launch from Java using the Pipeline.launch() method, after doing the necessary Java gstreamer initialization.

Thanks.

But i am not quite sure, that "mixing" is the right way to solve my
problem, is it? I am trying to merge multiple video files in a
sequence like this:

1.ogg -> 2.ogg -> 3.ogg -> ... -> n.ogg = all.ogg

You will probably need to demux each ogg file, than mux all the various tracks back into the output ogg. See oggdemux, oggmux gstreamer elemens.

My first approach is as follows:

gst-launch multifilesrc location="%02d.ogg" ! oggdemux ! theoradec !
theoraenc ! oggmux ! filesink location=output.ogg

but after the first file i've got a EOS message and the pipeline
stopped. So the output file looks like the first input file.

Are you trying to a: concatenate the files to play sequentially, b: mux them - so the user may select which video/audio to play, or c: merge video, so video from file2.ogg will be overlayed on top of the video from file1.ogg?

a) i'am trying to concatenate the files ;)

any idea how i can do it? :/

I don't know if it works in gst-java, but take a look:

http://gnonlin.sourceforge.net/

I think it is what you want, right?

Just to better understand:

http://www.jonobacon.org/2006/12/27/using-gnonlin-with-gstreamer-and-python/

A tutorial for python, but has the same idea to do in Java. Gnonlin is a plugin, so I think you can use like any other gst-element.

Thanks, but afaik it's not possible to add sources to the
gnlcomposition, is it? :/

You may also want to ask on the main gstreamer IRC channel or mailing list. If they can suggest a pipeline that will achieve concatenation, it can be launched from inside gstreamer-java.
