Hello, I am afraid I need more help with this. I do not understand. Are you saying that a file did not compile or just that I need to recompile with different options? (or both?). How can I tell which file did not compile? make completed and the binaries were created so I assumed it was ok. How can I compile a specific file with -O1, I assume I will need all the other complier options used in a normal build. Can you give me the actual commands? Let me know Thanks Matt -- Gee Broadcast Systems Telephone: +44 1256 810123 Web: www.geebroadcast.co.uk _______________________________________________ libav-user mailing list libav-user@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/libav-user
