I read it and applied what was necessary

+ temp_buffer = temp_buffer & 0xfffffff0;
+ switch(temp_buffer){
+ case VIDEO_OBJECT_START_CODE: VO++; break;
+ case VIDEO_OBJECT_LAYER_START_CODE: VOL++; break;
+ }
+ }
+ }
+
+ if (( VOP >= VISO) && (VOP >= VOL) && (VO >= VOL) && (VOP > 0))
in the patch it searched for the VOL and VO.

Is checked

Not correct for a probe, This happens not frequently in a random 2k
buffer. In a test stream it only happens at +/- 16k. And I think this
is too large for a probe buffer.
