You probably built the app_transcode application with an ffmpeg lib that
you downloaded and when it runs, it loads uses another library that may
come with your system.
Check how many ffmpeg libs you have and which version you are using. The
symbol that you mention is most probably from the libswscale.so (used to
resize the pictures).
