lls1 taken fromff130d7This is incompatible with libavcodec version 55.18.100 to 55.43.100 except 55.39.101 This incompatibility is caused by these libavcodec versions depending on a libavutil 52 which is ABI incompatible with the previous ABI 52 you can avoid this incompatibility by upgrading your libavcodec so it does no longer depend on the invalid ABI See:502ab21af0See:cc6714bb16See:41578f70cfSee: Ticket3136 Tested-by: marillat Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
