[Ambulant-users] Ambulant Linux 2.2b2 inBoundsEvent, audioVisualFade, oversized region smilText fade/in issues

[Kees Blom]

Hello Jose,

thank you for your interest in SMIL 3.0 and Ambulant, we appreciate that.

Also many thanks for your detailed bug report and extensive example.
I've filed these in our bug tracker at sourceforge.net # 2957973.

1. The Ubuntu build problem is probably caused by not having the libxml2 
package installed.
     ./configure should have given a warning for this.

2. <transition type="audioVisualFade" /> has not been implemented yet.
     The Linux player (gtk) indeed crashes when it tries to tell you that,
     as it also does when it tries to tell you that some <region/> does 
not fit in the
<root-layout/> specified.

This is an error in the error reporting code, needs to be fixed ASAP, 
but not so easy to do.

Probably "audioVisualFade" is easy to add, since the underlying components
have already been implemented.

3. I've not checked yet on your comment that smilText fades out but not  in.

4. The "inBoundsEvent" is indeed generated 10 pixels below the expected spot
     on Linux/gtk, not on Linux/qt; but there the TOC images are misplaced.
     Did not check on WinXP yet.

Regards,

Kees Blom.
