[Libav-user] FFmpeg libraries in Ubuntu

[JunHorng]

Thank you for your reply. I have done what you said, but the error message:

undefined reference to `avcodec_decode_video2'

is still shown. Besides, a warning message:

‘dump_format’ is deprecated

is also shown. Would you please advice me how you compile FFmpeg in    the
Ubuntu system?

Best regards,

Jun-Horng Chen
