I could not see --avformat-vdpau getting mentioned in mlt's configure script. As I said, I do NOT have libvdpau_va_gl on this machine because it did not work. But regardless, mlt works for me (but seems to hang at the end, needs Ctrl-C to kill it). I do not get anything like your [producer avformat] message. ĸen -- This email was written using 100% recycled letters. -- http://lists.linuxfromscratch.org/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
