The following line:

works perfectly with mencoder 1.0rc-2, but not with svn (trunk):

Something has changed between 1.0rc2 and the latest svn which

causes this.

Any hints? Thanks.

  • Resolution set to fixed
  • Status changed from new to closed

The solution also was to compile with my own flags (-O2 -march=native). As I said before, the excessive optimization causes the compiler to generate bad code.
