>Description:

transcode doesn't compile on recent -current systems due to gcc changes.
It will complain about unknown symbols ff_pw_20 and ff_pw_3 while linking.

The fix has been provided on the transcode mailinglist by Peter Knaggs.

>How-To-Repeat:

Try to make transcode in /usr/ports/multimedia/transcode
The error will happen in ffmpeg/libavcodec
