>Description:

MesaLib-21.3.9nb3

Both xine(1) and vlc(1) crashes, in various contexts, but always in MesaLib with vdpau and dri r600 drivers.

See PR pkg/57760 and pkg/57761.

For now:
- xine(1) can't do anything;
- vlc(1) plays mp4 but not DVD;
- ogle (not depending on hardware accelaration) plays DVD.



>How-To-Repeat:
On a node with a radeon (r600), try reading a DVD with vlc(1) or invoke without arguments xine(1).

 The bug is independent from screen depth.

 Was seen with a Screen depth of 16 bits. Switching to 24 bits doesn't
 circumvent the problem that lies, at least, with r600 radeon driver in
 MesaLib/gallium.
