GES Timeline

[Eloi Bail]

Hi all,

I was using GESTimeline to play continuously a media split in several files.

It was working fine so far ( I can chain my split media files and playback
them).
However, I need more feature and am struggling to know how to use classes
such as Asset, Clip, Track, TrackElement, Layout...etc

I would like to manage my playback in this way :

- manage multi-audio tracks. For the moment I am able to discover multi
audio tracks using GstDiscoverer but I do not know how to set / change an
audio track to my timelinepipeline
- manage audio and/or video tracks duration. For the moment I am setting a
global duration by media.
              sometimes have - audio track from file 1 = 1:59:50
                             - video track from file 1 = 2:00:00
                             - audio track from file 2 = 2:00:10
                             - video track from file 1 = 2:00:00

              I would like to have no gab on audio playing. So I would need
to deal with duration per track

I have several solution: Track, Clip, Asset and do not know what is the
best for my purpose (BTW I am using Gstreamer SDK 2012.11-1)

Could you please give me some advice ?

Thanks,

Eloi
