Description Adrien SCH. 2014-04-22 13:57:26 UTC 
Environment : GST 1.2.4

Use case : 
Concatene video files with the playbin element.

Scenario : 
Load a playbin element with a video file and link the video-sink to a ( mux ! filesink). Use the about-to-finish signal to switch the source location and switch at least 2 times.

Observation : 
The first segment (generate by the playbin change state) is correct, the seconds (file1 -> file2) is also correct (base value of the segment is correctly calculated), but after two switch (file2 -> file3) the segment event didn't contain a correct base value (set to 0). 

Test case : 
Will do asap.

Ping?
Comment 2 Adrien SCH. 2014-05-14 21:24:28 UTC 
I completly forgot to make a test case for this issue, and im still very busy..

I fixed this on my side but its probably cause by the stream sync inside the playbin that miss calculate the segment base.
Comment 3 Thiago Sousa Santos 2014-05-14 22:33:49 UTC 
Do you use a file with both video and audio and or only video?
Does it happen with every file?
Comment 4 Adrien SCH. 2014-05-15 08:15:26 UTC 
only video.

It happens (for me) with the matroska demux. On this case, I appended multiple video files without decoding the stream. I think that this is working when the playbin decode the stream, but I'm not quite sure about this.

Can you provide a testcase for this?
