[gst-devel] combine movie clips???

Thu Feb 8 12:03:10 CET 2007

I need to combine the clips in the command line though or through
executing a script...

Does gstreamer or pitivi provide a command line API which will let me
combine two movie clips and make them one???

this is hard to see if we can be of help without seeing what you wrote
down in your app for instance...
could you please post the code in which you use a bin to encapsulate
your element ?

do you link your sink pad with anything ?

The latest 1.8.x libmjpegtools release didn't include a required header
file (mpeg2enc/mpeg2syntaxcodes.h), so if you don't have that installed,
we won't build the plugin. Some distros have fixed their packages to
include it, others haven't.

In general, the config.log file will usually give you more information
about what exactly the configure script checked for and what failed.

Hi,

I would like to know if I could be able with gstreamer to combine to
movie clips, or a movie and a sound clip.

For example if I got two .avi files am I able to combine them and
produce a final .avi file which includes both of them?

Or if I got an mp3 file and a .avi file am I able to combine these with
gstreamer?

IF yes could you please point me to where I can find information about
how to do this as I have gone through the manual and I am not able to
see where it talks about it.

Regards,

Ioannis

Hi,

  You can use the PiTiVi video editor to combine several videos
together. It should work fine with latest 0.10.2 version. You can find
more information on the website : www.pitivi.org

    Edward
