[Libav-user] undefined reference to sws_getcontext

[Dmitry Adjiev]

Please let me know if  I understood something wrokt, but if this is libs
issue,  try to use the fllowing command line for compilation:
-lavdevice -lavformat -lavfilter -lavcodec -lswresample -lswscale -lavutil
-lbz2 -lm -lz -lpthread -lpostproc
Libs should be exatrly in this order
