Description

This patch fixing ocasional frontend crash and video stuck during DVB-S live tv playback when using hardware deinterlacer (detailed log included).

I using Radeon X1300 with oss drivers. In order to fix this issue i tried update mesa classic to galium but without success.

The problem is than "OpenGLLocker ctx_lock(gl_context)" was issued two times in the same context in functions:

VideoOutputOpenGL::SetupDeinterlace?

OpenGLVideo::AddDeinterlacer?

This also fixed ocasional log messages "VidOutGL: Couldn't load deinterlace filter" whish was related to this problem. The fix is valid for trunk and 0.24-fixes. This fix may be related to #9216 #9272

This patch is invalid since we use recursive qmutex. The problem must be hidden somewhere else, so please close this ticket.
